Glo Worm

Glo Worm is a stuffed toy for young children, designed by Hasbro's Playskool division, and made in Pawtucket, Rhode Island. Introduced in 1982, the plush, pajamaed worm body^[1] contained a battery-powered device that when squeezed would light up the toy's vinyl head from within, creating a soft glow.

The original Glo Worm, released in 1982, was the same shape until 2005

This article is about the 1980s toy series. For the insect larvae, see Glowworm.

The original toy, upon release, was such a success^[1][2][3] that Hasbro released a new Musical Glo Worm and Glo Bug in 1984, and a Glo Butterfly in 1985. A series of story books, night lights, videos and other merchandise was also produced until the early 1990s. However, in late 2005, the product was criticized for harming children;^[4] its plastic head was softened with phthalates, which can be dangerous if swallowed by children.^[5] The Glo Worm is still made today, although with an updated appearance.

Glo Friends

Playskool expanded its brand of "Glo" toys made of soft vinyl that glowed,^[6] and released The Glo Friends animated series in 1986.

American fast food chain Wendy's released a series of Glo Friends soft vinyl toys as a promotion in 1989.

In collaboration with Playskool, toy company PlayMonster expanded the Glo Friends with Wigglebug in 2022.^[7]
