Dexter plays with one of his limbless dolls as "Mr. Jones" and puts him in a toy car he uses as an Urban Terrain Vehicle, and he uses a toy dinosaur as the villainous Gordonzilla who then snatches up Mr. Jones, and the latter calls Dexter for help. Dexter is about to grab a wrench when Dee-Dee (clad in a karate outfit) grabs his arm, yells "Ashitake!", and throws him at the window, leaving a crack in it.
