The Pesties are the six tiny henchbugs to Huxley who first appeared in The Adventures of Elmo in Grouchland. According to the press kit, their names are M'Lady, Tanya, Lyle, Little Ricky, Howard and Sydney, but while the last three are named in the film (the red, orange, and blue ones specifically), the other blue one is referred to as Charlie. The colors for the remaining characters are lavender and tan.

Three of the Pesties appeared in the sing-along video The Adventures of Elmo in Grouchland: Sing and Play. They later made a cameo in Sesame Street 4-D Movie Magic as part of Oscar's polluted vision of Sesame Street, where they scurry through people's legs in the theater. In season 42 (episode 4260), they appear alongside Jason Jones on the program Grouchology.

The Pesties were performed by Kevin Clash, Fran Brill, Stephanie D'Abruzzo, Jerry Nelson, Martin P. Robinson and David Rudman.
