1x12 - The Adventures of Teddy Ruxpin

Tweeg sets out to sell miracle cures to the residents of Gimmick's Valley in order to pay his MAVO membership dues. He winds up talking the Trio into buying "cures" for "ailments" by playing on their insecurities (Gimmick's baldness, Teddy's shortness, and Grubby's lack of handsomeness). The Trio eventually realize they've been swindled, and vow to be happy with the way they are.
