The Dumps are a rowdy group of Ankylodumps who enjoy jumping ramps, racing and crashing into each other. No one knows when the Dumps first formed, but they first appeared in "Racetrack" when Drag-O, Wrecka and Scoot reunited with Ton-Ton, who used to be a member. The Dumps were too rowdy for them, so they built a racetrack for racing and used that same racetrack to decide who would make the rules. They also appeared whenever there was a big project such as in "Slide" and "Volcano". Also, Wrecka appeared in "Garby's Gang."
