The Shake Your Bacon Dance Competition was a contest held back when Mr. Wheelie was approximately a teenager. He, according to the episode Cheer Up, Wheelie, had trained to become part of the competition for years, and chose Nessie to be his dance partner. But, unfortunately, her blimp became involved in a freak weather accident, and Mr. Wheelie was disqualified. It was then that he decided never to dance and never to use his legs again.
