Trevor "Doom" Buck Huntley runs away from his hometown, Sunshine Hills, since he's angry at his mom for taking away his cellphone. He runs to Magnificentopolis, because it's "more swag than Sunshine Hills". Meanwhile, Little Grey, Ondelez and the rest of their family are taking a holiday in Magnificentopolis. Doom's face appears on a giant TV in the middle of the city declaring that he's taking over. Little Grey has a hammer, which he accidentaly throws, and since Doom's obnoxious square tooth is a magnet for hammers it flies in his face and knocks out his tooth. Ondelez and Little Grey run off because of this, and find help along the way.
