In the folklore of Cambridgeshire, the Shug Monkey is a creature that shares features of a dog and monkey, which reportedly haunted Slough Hill Lane. The creature, believed to have the body of a jet-black shaggy sheepdog and the face of a monkey with staring eyes, was believed to be a supernatural ghost or demon. Local writer and broadcaster James Wentworth Day, who first related stories of the Shug Monkey in Here Are Ghosts and Witches (1954), described it as a curious variation of Black Shuck, while local folklorist Polly Howat suggests that both share common origins in Norse mythology.
