49	1	"The Red Squirrel"[1]	Brandon Sawyer	Wolf-Rüdiger Bloss	March 13, 2010 (2010-03-13)	201a	4.3[2]
After the penguins discover him in an underground bunker, legendary penguin agent Buck Rockgut drafts them to assist with apprehending the Red Squirrel, a top penguin enemy once brought down by Rockgut who has since escaped. Severely paranoid that they may be Red Squirrel agents, Rockgut begins to detain several zoo animals. Throughout, only Private believes such is wrong. He eventually tries using Fred as a Red Squirrel stand-in to trick Rockgut, but it backfires when Rockgut suspects Private of being the Red Squirrel himself. The other three penguins soon recognize Rockgut's errant paranoia and get him to leave by telling him the real Red Squirrel was in a made-up place called "Grrfurjiclestan". Later, a periscope is shown and it is shown that the Red Squirrel is real. Special guest star: Clancy Brown as Buck Rockgut

After creating a time machine called the "Chronotron," Kowalski is in need of one final chemical before he can fire it up for time travel. However, when he and the other penguins are out to obtain it, Kowalski's future self appears to Private and instructs him to not allow his present self to complete the Chronotron, lest great chaos in the future result. Later, as Private has no success in foiling the Chronotron, another future Kowalski appears to Skipper to ensure that his future self instead build the Chronotron. Eventually, the three Kowalskis see each other, creating a black hole in space-time. Two Kowalskis use the Chronotron to travel back in time, thus becoming those who had appeared to Skipper and Private. The space-time hole is then shut when Rico throws the Chronotron into it.
51	3	"Gator Watch"[3]	Bill Motz & Bob Roth	Wolf-Rüdiger Bloss	May 15, 2010 (2010-05-15)	204a	3.8[4]
While the penguins are visiting with him in his sewer home, Roger, their alligator friend, states that he hates having to live there, but that he loves being in New York so much that he is willing to endure it. The penguins soon decide to help Roger find a better place to live in the city. They first hide Roger inside a log in a nearby pond, but a lady sees him and screams. They try hiding him as a display in a museum next, but Roger blows his cover by becoming "alive" when a boy pokes him. Following this, the penguins try to hide Roger on a rooftop as a gargoyle, but Roger, afraid of heights, soon falls into a public pool below. Throughout all this, the attempts to relocate Roger make TV news headlines, in a segment called "Gator Watch". While trying next to evade humans, Roger unwittingly enters onto a stage via a building's backdoor and is soon captured by animal control. The penguins then set off after the van transporting Roger to break him out, but they fail to do so before the vehicle arrives at its destination: a well-suited habitat at the Central Park Zoo.
52	4	"In the Line of Doody"[3]	Brandon Sawyer	Steve Loter	May 15, 2010 (2010-05-15)	204b	3.8[4]
In anticipation of the arrival of the zoo commissioner, a security detail quickly examines the zoo and its animals for threats. But as they leave, Skipper believes that the agents have done an inadequate job, so he and the other penguins take it upon themselves to ensure the zoo is safe for the commissioner's arrival to cut the ribbon on a new children's zoo. In doing so, they soon uncover that a pigeon, Frankie (Jeff Bennett), has plotted to "drop one" on the commissioner's suit in retaliation for his implementation of anti-pigeon park regulations. Skipper then tells the other penguins about how he had failed to act under similar circumstances when the previous commissioner had been attacked with bird droppings containing blueberries, vowing to not let the same happen again. The penguins then chase after Frankie, with Skipper flying through the air using a jet-pack, but the pigeon soon ends up releasing his blueberry-infused vendetta. Skipper dives in When Kowalski informs him that "The package has dropped" and takes the hit for the commissioner, and his team is horrified at the resulting look of their leader. Fortunately, however, Skipper reveals that he was wearing a "pigeon-proof vest" as he pulls it off his body. The vest is soon launched at Frankie via a makeshift cannon, resulting in the pigeon suffering the same fate he had intended for the commissioner. Guest star: Gary Cole as The Commissioner
53	5	"Can't Touch This"[5]	Bill Motz & Bob Roth	Tom Bernardo	June 19, 2010 (2010-06-19)	207a	3.7[6]
When the penguins hear the scream of a child, they soon learn it was the result of a boy having been bitten by a sheep at the zoo's petting zoo. Appalled by the sheep's attack, the penguins set off at night to retaliate against him. However, the sheep, Randy, soon tells the penguins that he was provoked to bite the boy because the boy had, among other things, beaten on him and had pulled out a clump of his wool. Convinced that they had wrongly judged Randy, the penguins decide to help him out to prevent further abuse by rowdy children. When their attempts at applying a slippery polymer, building up static electricity on Randy's wool, and hypnosis fail, the penguins decide to transport Randy to a farm to live out the rest of his life. Randy is soon taken to a farm by the penguins in a truck, but shortly after his arrival, Randy is horrified at the appearance of the other sheep there, who are sheered and appear to be in a cult-like trance. Consequently, Randy ends up back at the petting zoo, but when the same boy approaches him to attack him again, Randy kicks him away. It is then revealed that Skipper and Rico had taught Randy some of their commando fighting moves. Special guest star: Will Friedle as Randy
54	6	"Hard Boiled Eggy"[5]	Brandon Sawyer	Sean Kreiner, Fred Osmond and Christo Stamboliev	June 19, 2010 (2010-06-19)	207b	3.7[6]
While the penguins are engaged in a training exercise, Eggy the duckling enters the HQ, acting in a commando-like fashion. His mother soon locates him there, and tells the penguins that Eggy has been behaving that way ever since their egg-watching adventure. As requested by Eggy's mother, the penguins agree to work with Eggy to convince him that he is not suited to engage in their para-military operations. But when he persists in desiring to become a commando, Skipper leads Eggy to believe that he needs to have a "Penguin Commando License" in order to partake in their operations, and that being able to tackle all the zoo has to offer is requisite for obtaining such. Although briefly successful, this plan soon backfires when Eggy begins to take down all the zoo animals, using the specialized characteristics of each of the penguins that he had learned from them while still in the egg state. Eventually, Julien is the last animal that Eggy had not yet beaten, and thus the only thing standing between him and his "license". But Julien, upon learning that "[his] J.J." (Eggy) wanted to become a penguin, begins dancing to music, and Eggy fails to bring him down as a result. Eggy is then cured of his commando desires but, to the dismay of the penguins, now has taken up Julien's behaviors.
55	7	"The Lost Treasure of the Golden Squirrel"[7]	Eddie Guzelian	Tom Bernardo and Christo Stamboliev	July 19, 2010 (2010-07-19)	205	N/A
One century ago, the Golden Squirrel places the key to a hidden treasure into a time capsule to be buried in commemoration of the opening of the Central Park Zoo. When the time capsule is opened in the present day, the race is soon on between the penguins, lemurs, Marlene, and Fred to reach the legendary treasure before King Rat and his minions do. However, matters become complicated for the zoo gang along the way when the rats catch up to them and carry away Marlene in a failed attempt to gain possession of the key to the treasure. Later, the group displays symptoms of infighting when they confront their individual depraved desires for what could be done with the treasure once claimed, a curse forewarned by a mysterious, elderly squirrel who had stated prior that the treasure had to be destroyed. Eventually, after having gotten a hold of the key, the rats locate the treasure, but the gang soon catches up to them. Following a little more fighting amongst the group, it is revealed that Julien, as the "pure-hearted one" among them, is immune to the treasure's curse, and he proceeds to dispose of the treasure. When the animals return to the zoo and discuss their adventure, a pigeon comes by and asks Private to guard a crystal feather, but everyone but Skipper soon disperses, not wanting anything to do with another ancient mystery. Special guest star: Debbie Reynolds as Granny Squirrel Note: This is a half-hour episode.
56	8	"Fit to Print"[8]	Eddie Guzelian	Steve Loter	July 19, 2010 (2010-07-19)	209b	N/A
The lemurs interrupt the penguins playing computer solitaire in the zoo office in order to sneak a peek at the zoo's new advertising campaign photo, which features the lemurs. After being chastised by the penguins for creating a threat of being seen by humans, Julien points out that the penguins can be seen in the background of the approved ad photo in commando fashion, seemingly unaware that their photo was being taken. Back at their HQ, the penguins decide to set out to digitally remove themselves from the image before it is sent to the ad agency. Whilst attempting to do so at the photographer's house, however, Kowalski inadvertently sends an enlarged version of the incriminating area of the photo to the ad executives. Their situation is made progressively worse when their visit to the ad agency results in the photo being sent to the printer with the caption "Killer Commando Penguins," and then when their attempt to reconfigure the 10,000-copy print job at the print shop instead results in a 1,000,000-copy authorization. When their final attempt to stop the presses results in the foursome being caught up in and inked-up by the machinery, they retreat to the HQ, convinced their covert ops will soon be exposed. However, the new ad which Alice reveals, of penguin body shapes splatted on a white background, keeps their operations secret.
57	9	"Operation: Cooties"[9]	Ivory Floyd	Tom Bernardo and Sean Kreiner	July 19, 2010 (2010-07-19)	210a	N/A
When Marlene comes to the penguins' habitat with leaves she says act as an "organic moisturizer," Private, Kowalski, and Rico rub them over their bodies, as does Marlene. Meanwhile, Julien observes a group of schoolchildren running around, some claiming to have gotten "cooties" from others. This observation soon starts a panic when he, Maurice, and Mort come to the penguins' habitat and report this ailment, which Kowalski concludes is spread by the touch of girls. When the group observes Marlene in Burt's habitat and both of them itching, they infer that the otter has cooties and should be avoided whenever she is around. When Mort is thrown at her by Julien, he is quarantined by the penguins, as are Private, Kowalski, and Rico when they exhibit itching symptoms. Eventually, Marlene comes to the penguins' HQ looking for a cure for her itchiness, but is sent away by Skipper after she chases and touches him. Alice soon finds her, however, and she and the penguins are placed in an oatmeal bath in the vet for relief from what they soon learn from the doctor is poison ivy – Marlene's so-called moisturizer. Private wonders if someone should tell Julien, but Skipper thinks it's no rush. Meanwhile, Julien, Maurice, and all the animals are in the shop itching like crazy.
58	10	"Mr. Tux"[10]	Eddie Guzelian	Wolf-Rüdiger Bloss	July 19, 2010 (2010-07-19)	211a	N/A
An armadillo who goes by "The Amarillo Kid" enters the penguins' habitat looking for someone he knows simply as "Mr. Tux". Private admits to being him, and the Amarillo Kid insists that Private engage in some sort of "unfinished business" with him, but Private refuses. Soon, the nature of Private and the Amarillo Kid's past is shown: Private was once a skilled mini golf player, but quit the sport after a tough game against the Amarillo Kid forced him to have to ricochet a ball off a young opossum girl's ice cream cone, ruining it. Private is blackmailed by Amarillo Kid to do another round of mini golf only after he sets the penguins' HQ to self destruct and locks-down the rest of the zoo. When Private's game-winning putt comes a mere fraction of an inch from going into the hole, the Amarillo Kid celebrates his long-awaited defeat of Mr. Tux. But Private's ball then rolls in, giving him the victory, with an assist by a cricket Private had avoided hitting earlier while driving the penguins' car.
59	11	"Concrete Jungle Survival"[10]	Brandon Sawyer	Steve Loter	July 19, 2010 (2010-07-19)	211b	N/A
Private desires a promotion after Skipper forbids him to look at a joke contained in a classified mission file. Skipper agrees to such a promotion, but only if Private can pass a one-on-one survival test against "the most fearsome beast in the concrete jungle" on the streets of New York, where he is soon taken. Left alone in an alley, Private is passed a cassette player by the other penguins containing audio instructions on how to outwit this enemy. However, Private's test is soon interrupted by the arrival of the lemurs, who believe they are on a camping trip and consistently get in the way of Private trying to follow the tape's directive. Eventually, Kowalski reveals the specificity of the enemy Private must confront through song: an evil, ghostly city bus notorious for making roadkill out of animals known as the "Graveyard Eight". In order to pass his test, Private must confront the bus and bring back a souvenir from it. This inevitable confrontation occurs when the bus comes by while the lemurs are "sewer fishing" and entangles their fishing lines in its bumper, taking them with it as Private races to catch up. Julien soon gets himself free, but goes inside the bus with Private to look for something sharp to free the others, which Private accomplishes with the name badge of the driver, a short, elderly woman with a deep, demonic voice. For his successful encounter with the Graveyard Eight, Private is promoted to Private First Class. He is finally able to read the joke, but in the end, he doesn't quite understand it.

Private is distraught when cockroaches appear in the HQ, taken in by Rico when threatened by an exterminator. In order to help the cockroaches return to where they originated, the penguins and roaches set out on a mission to defeat the exterminator. Following a long stakeout, Officer X, now an exterminator, arrives on the scene, and soon manages to tie up Skipper, Kowalski, and Rico as Private slips away. To save his teammates and defeat X, Private temporarily suppresses his feelings of disgust and covers himself with numerous roaches, which crawl off him and into X's clothing when the lights are turned off. X subsequently runs out of the building and Private suffers a delayed case of "the willies". Special guest stars: Jerry Trainor as the lead roach, Zand Broumand and Brian Posehn as other roaches

After securing pretzels from a pretzel cart, the penguins notice that a boy on a school field trip had observed their operation, and believe him to be composing a dossier on them. Rather than take immediate action against him, Skipper instead wants to focus on the boy's "spy master," and they soon discover a museum brochure which has an exhibit on Madagascar, further adding to Skipper's suspicions on the boy. Julien then comes by and notices that his "royal booty scratcher" was in the photo of the museum display and requests the penguins get it back for him. When they turn him down, Julien assembles a ragtag "team" of his own to do the mission instead, with Mort taking on the role Skipper would for the penguins, Fred for Kowalski, Maurice for Rico, and Julien himself for Private.[12] Meanwhile, the penguins observe the boy, Ronald, telling his teacher about having seen their operations, but the teacher rejects his account. Shortly after, the school group leaves for the museum. At the museum, the lemur-led group pursues Julien's booty scratcher and the penguins attempt to get a hold of Ronald's notebook, leading him to again tell his teacher about being pursued by the zoo penguins. The penguins ultimately fail to obtain Ronald's notebook before the children leave the museum, in part because they got Julien's scratcher for him, but they successfully use a brainwashing helmet on the teacher after she reads Ronald's report. Special guest star: Nathan Kress as Ronald

Afraid, Private begins to panic, but Marlene drags him to the exhibit to meet the badgers and get over his fear. When the two meet the friendly badgers, Becky and Stacy, all four soon become friends and spend the rest of the day together. But after the badgers surprise Marlene in her habitat that night, make her partake in undesired adventures, and fail to leave her alone, Marlene insists that they stop "badgering" her. Becky takes the remark as an insult, and Marlene soon fears retaliation from the angry badgers. Later, in a chase, Marlene and the badgers end up in the park, knocked into it by tennis balls launched by Private, where Marlene reverts to her wild form and easily takes down Becky and Stacy in a one-sided tussle.

After Julien interrupts the penguins' mission to destroy classified files with an undisclosed problem, Skipper dispatches Rico to take care of the matter. At the lemur habitat, Julien complains to Rico about a nearby billboard which he finds bothersome, which Rico soon destroys with dynamite. Having been denied the usage of dynamite in the destruction of the files earlier, Rico greatly enjoys his work, even after the other penguins come over to investigate the blast. Julien then desires more things blown up, but when Skipper warns of the consequences of an uncontrolled, wild Rico, Julien and Rico agree not to continue. However, the two soon act to the contrary and engage in a montage of blowing things up. Eventually, dynamite-happy Rico reaches his breaking point due to all the "psychotic pressure" built up inside him in consequence to his frenzy of creating explosions, and he begins to use his own body as a walking wrecking ball. To protect the zoo from Rico's destruction, the penguins and the lemurs trap Rico underneath Julien's bounce house, which Kowalski believes will serve as an "ideal lunacy absorber". The plan works, and soon Rico falls asleep, tired out by his "48 hours of uncontrolled mayhem".

Kowalski has invented a helmet that turns thoughts into actions, essentially granting the wearer the power of psychokinesis, which he dubs "the Helmet". While the penguins are playing with its power, King Julien notices it and becomes incredibly jealous. Late that night, Julien steals it and claims it as a crown to use its power for himself. Now with unparalleled powers, King Julien fires Maurice, now no longer needing his services since the Helmet now provides everything he needs, and continues to abuse the Helmet's power for himself. However, upon setting its power to 10 (the highest), Julien's thoughts and words become reality and cause chaos in the zoo until it eventually creates a tornado of telekinetic objects. In the end, however, the penguins separate the helmet from King Julien's head, ending the telekinetic madness (but at the same time burning off all his head hair) and Maurice returns to serve King Julien by giving him his old crown back to hide his baldness.
65	17	"Night and Dazed"[16]	Kurt Weldon	Emmanuel Deligiannis	September 18, 2010 (2010-09-18)	206a	4.2[17]
In the course of testing the HQ's new evacuation system, Private is flung into the koala habitat. When it soon becomes night, the marsupial, Leonard, awakens, terrified of Private since he is one of the zoo's "dangerously psychotic" penguins. After assuring Leonard that he has no intent to hurt him, Private leaves the koala habitat, only to return the next day to find him unconscious. Fearing for him, Private brings the koala back to the HQ, where Kowalski explains that koalas are nocturnal and Leonard himself awakens from his slumber as night approaches. While there, Leonard is accidentally launched from the now-overhauled HQ evacuation system and touches down in Midtown, provoking the penguins to set out to find him and bring him back to the zoo. Soon after locating him, however, their situation becomes more difficult when Leonard falls asleep in the daylight. Eventually, the team manages to get the sleeping Leonard back into the zoo just shy of nightfall, and once night comes, Leonard awakens and spots Marlene and fears her in the same manner he had the penguins, which Skipper chalks up to Marlene apparently having a bad reputation herself. Special guest star: Dana Snyder as Leonard

When a boa constrictor arrives at the zoo from Hoboken, Skipper and Kowalski warn of the snake's dangers at a zoovenir shop meeting. Shortly thereafter, when Mort goes missing, the penguins confront the boa, Savio, to see if he had any role in the disappearance, but it is apparent from the configuration of his habitat that he had no means of escaping the enclosure. Later, when Maurice and Marlene go missing, the penguins continue to suspect Savio of eating the small mammals, and soon send Private out as bait, dressed as a monkey. When he disappears, the other penguins and Julien confront Savio once again, whereupon he breaks free from his enclosure by sending his tail through a ventilation shaft and deactivating his habitat's electronic locks via a keypad. Savio consumes Julien during the ensuing confrontation, but is ultimately defeated by Burt, who smacks Savio around before forcing those eaten to be expelled. Savio is then sent back to Hoboken the following morning. Special guest star: Nestor Carbonell as Savio

After being accidentally knocked under a pile of pennies, Private is ordered to get rid of the coinage. While at the zoo's fountain to do so, Private notices Mort biting into a penny and advises him to toss it into the fountain to make a wish instead. Wishing for gumballs, Mort tosses the penny in and, to the serendipitous surprise of Private, gets them, leading Private to conclude that the fountain is magic. After telling the other penguins, Skipper warns that the fountain should be kept secret for fear of a careless wish wreaking havoc or exposing their operations, and limits his men to one wish each. However, Julien soon learns of the fountain's power through Mort, as does the rest of the zoo through Julien's exposure. Following the penguins warning the other animals about the potential dangers, Alice spots Private out of his habitat, but he manages to get away from her. But Alice then finds a penny and tosses it into the fountain, wishing she knew what the story was with the penguins. Her wish triggers Kowalski to accidentally blow his plasma blaster, which he had wished for, through the top of the penguin habitat, exposing their HQ to Alice and soon resulting in the foursome being caged to be studied and dissected by the government. But just as the penguins' future looks bleak, Private manages to get a penny into the fountain as the caged penguins pass by it and unwishes everything, setting things back to normal. Kowalski then convinces Private that his belief in the magic fountain was a delusion caused by Private's bump on the head, but Burt is seen with a French baguette and wearing a beret, and since he had wished for a trip to Paris, suggests that it may not have been a delusion after all.
68	20	"April Fools"[18]	Bill Motz & Bob Roth	Emmanuel Deligiannis	October 2, 2010 (2010-10-02)	208b	3.8[19]
After Julien discovers that Mort ate his fudge pops, Mort claims "April fools" in defense. After stating that April fools is not going to suffice due to it now being August, Maurice explains to Julien about how the April Fools' Day concept works each April 1. Enthused, Julien then decides to set about pulling pranks on the zoo animals, claiming that it is OK to do so in August because he had only just learned of the concept. After pranking Burt and Mort, Julien pranks the penguins three separate times claiming falsely that he was in need of their help. After the third occasion, the penguins assemble to engage in "prank resistance training" so they can resist the urge to respond to Julien crying wolf in the future. Meanwhile, Roy becomes infuriated at Julien for drawing on his backside with marker, which soon escalates to the point where Julien now has a real reason to request assistance from the penguins. Now trained to resist, however, the penguins reject that Julien is in dire need, but they later catch up in time to launch sleep grenades at Roy (Danny Jacobs) to save Julien from the rhino's charging wrath. When Roy soon awakens and begins to charge again, however, it is the penguins who have the last laugh when a stuffed penguin takes the blow and Julien momentarily believes it was Skipper.

After Julien tells Rico to do whatever the doll says, which Rico takes to the extreme, eventually turning into a hippie, but when the doll suggests to Rico that they become "special friends" Rico is devastated, believing that she no longer loves him.

Hans states that he has come to make peace with Skipper for past injustices, but Skipper refuses to accept the puffin's apologies. Eventually, widely due to the pressure of the other penguins and Marlene, Skipper offers Hans his "flipper in friendship," but the group is soon tied-up by Hans via an "exploding rope bomb" – the whole apology act was a sham. Hans soon brings the group to Julien's plastic volcano to trap them, but the penguins soon escape, leaving Marlene alone. After a chase, Hans locks himself in the penguins' HQ and begins eying their weapons cache. Eventually, after the penguins' failed attempt to steam Hans out of the HQ, Hans and Skipper meet up and fight using fish as swords. Held at fishpoint, Hans begins to cry, stating that he has no home and that his takeover of the HQ was mainly so he could have a place to live. Skipper then arranges to ship Hans to the Hoboken Zoo, a place he describes as a "disease-riddled cesspool".

Despite Skipper forbidding him to invent, Kowalski defies him and constructs an invisibility ray. While testing it in the park, the device itself is accidentally turned invisible when Fred falls on it; shortly, it also gets loose on the streets of New York because of Julien's meddling, firing its laser randomly and rendering objects in the city invisible. The four penguins soon go on a mission to stop the device, Skipper believing Dr. Blowhole is behind the mayhem. The team manages to ram the unseen ray with a bus and Kowalski successfully defuses the device following a resulting overload. Objects once invisible, including the ray itself, become visible again.

When he shows emotional indifference to a device-predicted fall of a child's ice cream, Private mutters "... detect this!" and chucks a fish at him, which Kowalski dodges, but it sets in motion a chain reaction, resulting in a baby stroller rolling out of the zoo. The penguins save it from the peril of traffic, then attempt to calm the baby by changing his diaper and giving him a stuffed penguin.

He hastily tries to rebuild it, using one of Kowalski's latest inventions, The "Neurotronic laser targeting system". Rico feels guilty for what he's done to the car, meanwhile the automobile soon begins to act "haunted" as it attempts to vengefully run down Rico repeatedly. The penguins soon catch and they attempt to stop the car from hurting Rico. After the car knocks Skipper unconscious, Rico finally gains the courage to save Skipper and destroy the car with a bomb. After the car is destroyed, the Penguins notice Kowalski's targeting system was placed inside and thus Rico admits that he disobeyed orders when he took the car out at night.

Meanwhile, Kowalski unveils a thought-reading device to the other penguins, but it soon catches fire due to its "cheap circuit board". As Mort continues his focus on his new game, Julien becomes disappointed that Mort is no longer obsessing over his feet and giving him the thrill of kicking him off. After failing to get Mort interested in his feet again, Julien teams with Kowalski, who wants to use the game's circuit board for his invention, to separate Mort from the game. The plan works, but the other penguins' disappointment in Kowalski's selfishness prompts him to want to return the circuit board, though it, too, soon malfunctions. The penguins and Julien then procure a new device from a toy store, only to find that Maurice had given Mort a cell phone to pacify him in the interim, which he now finds enjoyment in.

Said shuffling results in the lemurs being tasked with obtaining a Christmas tree, while Skipper has to take on the role of Santa. In hopes of being able to find "Santa's magic," Skipper and Private set out to locate the jolly old man, only to encounter multiple bell-ringing Santas and such look-alikes. Meanwhile, as the lemurs hunt for a tree before ultimately stealing one akin to the one in Rockefeller Center, chaos ensues at the zoo between different groups of animals over whether decorations should be rock and roll-themed or Dickensian.

The truth is finally revealed, however, when Frances puts Skipper down a chute into the ground, where he meets his teammates and the real Hoboken Zoo animals. Kowalski then explains that Frances had used the massage chairs to copy each animal into an android so as to have a clean zoo and be free of its "dirty" animals.

Alone on a secret mission in Shanghai, Skipper walks into a trap set by Hans and Dr. Blowhole which results in Skipper's memories being taken from him by Blowhole's "mind jacker" device before he falls into the ocean. Blowhole plans to use the mind-jacked information to aid in assaulting the penguins' HQ. Later, Skipper washes up on an island, confused about where he is and how he got there. To aid in helping him regain his memory, Skipper's mind hallucinates a "spirit guide" for him to follow in the form of Alex, a lion who had once been a Central Park Zoo neighbor. With "Alex" accompanying him, Skipper sets out to return to New York. Meanwhile, Blowhole has unveiled his Diaboligizer invention to his lobster minion Red One, a device which transforms those hit by its ray into evil creatures of destruction. Blowhole plans to use the Diaboligizer on Kowalski, Rico, and Private, and heads to Manhattan to carry out his plan. He enters the penguins' HQ at the same time Julien and Mort are attempting to pilfer Kowalski's experimental power cell, which Julien wishes to use to replace the dead battery in his MP3 player. With the power cell inside, the Diaboligizer's ray hits it instead of the penguins, resulting in the device increasing in size, floating in the air, and creating an energy bubble which causes the whole zoo to speak only through song. Blowhole manages to exploit this development by singing to tame the mutant MP3 player in order to take control of it and then leaves the zoo with it to unleash his wrath against the city. Skipper then returns and the penguins and lemurs then set out to stop Blowhole, which is accomplished when Skipper's singing serves as a distraction so that the power cell can be removed from the MP3 player. Skipper then activates Blowhole's mind jacker on him and Blowhole returns to Coney Island to perform as "Flippy". Back at the zoo, Skipper thanks "Alex" for being a helpful "spirit guide" and helped him to get back to the zoo.

Kowalski unveils his latest invention: "nanites," tiny robots which are capable of operating any mechanical object, thus freeing the penguins of time spent on chores. Skipper initially fears the nanites will become another of Kowalski's disastrous inventions, but changes his mind after Kowalski demonstrates that the nanites are programmed to not allow any harm to come to a penguin. Unfortunately, the programming has the unintended consequence of the nanites becoming overprotective, first by inhibiting the team's rescue of Barry the poison-dart frog when his tongue is caught in the cotton candy machine- although they are able to outmaneuver the nanites and save Barry anyway- and later by containing them in their HQ. The nanites fight back against the penguins' attempts to shut them down by assembling a large robotic form from various pieces of technology around the zoo, but are unstoppable until Kowalski is injured after his attempt to hit the robot with an EMP causes it to fall on top of him, with the nanites then self-terminating because they had violated their penguin non-harm protocol.

However, the Red Squirrel then shows up and it is revealed that Rockgut himself was Red's sleeper. Rockgut is then ordered to take out the penguins with a T-shirt cannon, but the penguins manage to confuse him, by wearing eye patches, into thinking they were also Red Squirrels. The real Red is then captured.

Against Alice's prohibition, a woman named Gladys sneaks various snacks to the zoo animals, as she had done previously. The animals all appreciate her, except for the lemurs, who Gladys believes are cats and are given cat food. When Gladys slips on a mango pit in front of the lemur habitat and hurts her arm, Julien is faulted by the other animals for throwing the pit into her path. They then seek to punish him by allowing Kowalski to use his "Rump-Whomper" device to spank him. All the while, Skipper's gut—literally, through grumbling—keeps telling him that Julien is innocent, and he seeks to clear the lemur of any wrongdoing. In the end, Skipper takes the punishment for Julien after determining through video that he had inadvertently set off a chain of events that led to the pit landing in Gladys' path.

Kowalski is ecstatic to learn that the Invexpo science convention has come to Central Park, only to be unable to attend after accidentally pulling a billboard down on himself, which fractures his legs and confines him to the nursery for a 30-day recovery. To liven Kowalski's spirits, Private suggests that he, Skipper, and Rico attend Invexpo instead; Skipper reluctantly agrees, finding the event surprisingly fun. Meanwhile, Kowalski's sanity quickly deteriorates from the boredom of confinement and the inability to attend Invexpo himself. But later, when he notices a space squid landing and the rest of the team unaware, he gets Marlene's attention to assist. After it takes Kowalski's Extend-o-Grab invention because of the hand–finger capabilities space squids lack, the creature returns to the sky after Marlene uses the invention to poke at the invader. Afterward, Kowalski no longer feels upset about not attending Invexpo, as he had "already witnessed the greatest invention this world has to offer"—his own.

After getting a splinter in his rear from sitting on his throne, Julien wishes to replace it with a new one. Meanwhile, at the penguins' HQ, Rico accidentally brings a long-hidden project, S.T.A.N.K., into view. S.T.A.N.K., a stink bomb-armed toilet once intended to trap Dr. Blowhole, was abandoned after the penguins discovered that dolphins do not use toilets. To now permanently get rid of it, the penguins decide to transport it to a highway rest stop. But Julien, desiring it for his new throne, pursues with Maurice and Mort and subsequently gets himself strapped to the S.T.A.N.K. upon sitting on it. With the S.T.A.N.K.'s core approaching meltdown, Kowalski and Maurice return to the zoo to try to figure out how to safely free Julien without the bomb detonating. It is ultimately determined that sodium chloride will short out the lock on the restraints, and that tears would be an effective solution. After Julien is unable to cry on command, Skipper thinks of all the time he had wasted with Julien and sheds a single tear, unlocking the restraints just before the S.T.A.N.K. explodes.

Following the fourth failure of Kowalski's "Nextoskeleton" invention in many months, Private spots something more horrific than Kowalski's crash: an unflattering doodle of himself on a nearby wall. Private then asks the snail that drew it why he had done so, and learns that the snail, Dale, hates him for having stepped on him the previous spring in the park. Private has no memory of the incident, but wishes to make things right; his efforts result in accidentally crushing Dale twice more, causing the other animals to believe that Private is a monster. King Julian tries to help Private, but ends up making things even worse for him. Later, Dale gains access to Kowalski's Nextoskeleton and wishes to exact poetic justice: to step on Private the same way he had been stepped on with the suit, leading to a battle between the penguins and Dale. But when Private points out that the suit belonged to Kowalski and that it was he who stepped on Dale, not Private, Dale realizes his mistake and apologizes to Private for the misunderstanding, agreeing to tell the others that Private is not a monster, but after he takes his revenge on Kowalski. Special guest star: Lewis Black as Dale

Hunter, a young leopard seal pup, is accidentally brought to New York inside the fishing nets of Antarctic poachers Cecil and Brick. Though fearful of her at first, after he rescues Hunter from a fish-processing hopper, Private asks the other penguins to help return her to Antarctica. Though Hunter presents herself as a non-penguin-eating "fishetarian," the others fear her predatory instincts and decide to help her only as far as launching her from the HQ into the East River with the instruction "go south". Not wanting Hunter to have to travel to Antarctica alone, Private launches with her, forcing the others to have to follow by submarine. In Antarctica, a group of leopard seals led by Hunter's father wishes to eat Private, but he is quickly declared off limits after Hunter tells of Private saving her. The other three penguins, however, are slated to become a meal. Hunter and Private try to explain that seals and penguins need not be predator and prey, but the message is lost when Hunter shows off a friend move she and Private had done together involving shaking Private in her mouth, which is misinterpreted as a hunting technique. After feeling sad that she is not understood, Hunter, along with Private and Julien, who had been a submarine stowaway, rescue the other penguins, though the hungry seals pursue. But when Private saves Hunter's father from falling off a ledge in the process, he accepts that natural instincts are not everything. Note: This episode was a half-hour special Special guest stars: Ciara Bravo as Hunter and Ed O'Neill as her father
111	63	"The Big Move"[53]	Thomas Hart	Tom Bernardo and Carson Kugler	January 16, 2012 (2012-01-16)	239a	N/A
After the lemurs enjoy a night out in the park that had also given the penguins a better night's sleep, Skipper decides to help the lemurs continue to slip into the park via a secret tunnel, though the other penguins express concern. Julien is instructed to keep quiet about the arrangement, but soon spreads the word anyway, resulting in many of the zoo's animals venturing into the park at night. Skipper believes everything will be OK when the penguins discover this, only for Burt to complicate matters when he jackknifes himself inside the tunnel once morning comes, creating a traffic jam of sorts for the AWOL animals. While Kowalski tries in vain to free Burt, the other penguins attempt to delay Alice and the visiting Commissioner McSlade from discovering the absences. Ultimately, Julien unintentionally frees Burt when he opens a water main, believing it is a "smoothie pipeline," which blasts the animals back into their respective habitats.
112	64	"Endangerous Species"[53]	Gabriel Garza	Sean Kreiner	January 16, 2012 (2012-01-16)	239b	N/A
The penguins wish to bring an extinct Waitaha penguin back to life, but end up cloning a dodo instead due to Skipper's grabbing of the wrong feather from the museum during a hasty retreat. The cloned bird, Dode, after introducing himself as a daredevil, manages to subsequently blow himself up with Rico's flamethrower just as the penguins begin to discuss how to help him. Dode is then cloned repetitively, only to manage to get himself killed through various reckless actions each time, which Kowalski attributes to dodo DNA having evolved to lack fear genes through centuries of having no natural predators. The penguins then insist that their next Dode wear safety gear, and chase after him when he refuses. In the process, Kowalski's cloning machine is accidentally tipped over, cloning untold numbers of dodos before exploding and losing its life-giving Higgs boson particle, making future cloning impossible. These final Dodes then recklessly kill themselves, except for one which the penguins manage to save by daring him into having a staring contest with a taxidermied dodo at the museum, which he begins doing for perpetuity. Special guest star: Brian Stepanek as Dode
113	65	"Loathe at First Sight"[54]	Justin Charlebois	Fred Osmond	February 11, 2012 (2012-02-11)	227a	N/A
In an effort to make Doris the dolphin wish to be more than just friends with him, Kowalski invents the "Love-u-Laser," a device designed to render the subject of a laser blast in love with a pre-selected target. But after proving its capabilities on few zoo subjects, Kowalski is ordered by Skipper to reverse the actions. But in the process of doing so, the Love-u-Laser jams and then fires unexpectedly at Private, who within moments angrily tackles and yells at Kowalski. Kowalski believes that Private's state can be reversed, but after procuring the necessary compound for the Love-u-Laser, it once again malfunctions, casting its beam of hatred across the zoo and resulting in Kowalski being violently loathed by everyone else. As they surround him wishing to do him harm, the Love-u-Laser's effects are finally reversed when it falls into the fountain and causes a loathe-reversing beam to be cast across the zoo. In the end, a disheartened Kowalski destroys the Love-u-Laser, but Private enlightens him with the fact that maybe he and Doris will get together one day.
114	66	"The Trouble With Jiggles"[32][54]	John Behnke & Rob Humphrey	Sean Kreiner	February 11, 2012 (2012-02-11)	227b	N/A
Kowalski is court-martialed for having intentionally failed to destroy his gelatinous "Jiggles" creation. Through flashbacks beginning when Skipper discovered that Kowalski still possessed Jiggles, it is shown that Kowalski believed Jiggles could now be safely kept because he had altered it to consume whipped cream instead of fruit. Skipper, however, still believing that Jiggles is dangerous, attempts to smash it with a baseball bat, only for Jiggles to unexpectedly subdivide from the impact. The situation is exacerbated when Skipper continues to hit the resultant "Jiggli," producing more and more with each blow, and when the cubes escape the HQ, they multiply more as the zoo animals impact them without realizing the consequences. A plan by Rico to lure the Jiggli with a mound of whipped cream and then blow them up instead results in Jiggli raining from the sky. At the end of the court-martial, Rico attempts to pour some whipped cream onto a pie, only to attract the Jiggli into the HQ, where they are eventually neutralized by Kowalski's idea to lower the temperature of the HQ to freeze them. The frozen cubes are then loaded onto a rocket which lands on Mars, where the revived Jiggli then attack a group of space squids.
115	67	"Alienated"[55]	Bill Motz & Bob Roth	Sunil Hall and Robert Lence	March 31, 2012 (2012-03-31)	217a	N/A
"Lemmy" the life-emulating robot returns to the zoo from Mars with an unwelcome visitor: a space squid which bursts out of his chest compartment, damaging him. After the squid immobilizes Mort with a phlegm-like substance, the penguins, lemurs, and Lemmy's head begin to hunt it down in order to protect the zoo and ultimately the planet from further invasion. Now larger in size, the space squid soon renders each penguin and lemur immobile. The alien is ultimately defeated by Lemmy, once his body had reconfigured itself through an automated process, using a combination of dance and fighting moves under the verbal direction of Julien and Skipper.
116	68	"The Most Dangerous Game Night"[56]	Brandon Sawyer	Emmanuel Deligiannis and Brian Hatfield	March 31, 2012 (2012-03-31)	232a	N/A
Marlene plans a zoowide game night, hoping that it will bring the animals closer together. Skipper, however, questions if Marlene can handle a game night and warns that her idea could turn on her. As the other animals partake in game night, Skipper observes to ensure that everything remains orderly, and stays behind when Maurice, Mort, and Kowalski leave the zoo to procure more party mix from a local snack store after Julien eats all of it. While they are gone, Skipper's earlier fears begin to come true as the animals begin to not get along with each other due to the games. Meanwhile, a silent alarm is set off at the snack store, summoning the police and trapping Maurice, Mort, and Kowalski inside. When the zoo animals learn of the three being trapped on TV, Skipper seeks Marlene's help to rescue them by organizing the animals to improvise various games on the street to take down and distract the police. The plan succeeds, as does Marlene's original goal of bringing the zoo together.
