Mindy, as usual, insults Mandy's appearance, which causes Mandy to wonder whether she is truly pretty or not. (She asks Grim and Billy which caused them to burst out laughing continously over the course of a few days) Mandy decides to enter the school beauty pageant, titled "The Little Miss Scurvy" pageant for the "scurvy prevention week". Grim summons the Underworld Makeover Artist, Crabena, who says that Mandy has no chance winning the pageant if she keeps her sour attitude. They all try to make Mandy smile. At the grand finale of the pageant (while Mandy is singing "Over the Rainbow"), Mandy finally smiles, causing reality to be torn asunder.
Grim, Billy and Mandy wake up and find they've been transformed into the Powerpuff Girls, with Grim as Blossom, Mandy as Bubbles and Billy as Buttercup. After flying off to answer a call from the Mayor, they agree to return to Endsville and never mention this incident again.
