Summary Roving Eye announces a superhero fitness test during which the Superchums create a great mess in Crumptonville. Amongst the clutter Mr. Bad and Appliance find the plans of a giant screw holding the city to Mount Crumptonville. They decide to unscrew it and let Crumptonville fall into the sea, but the bolt creates a very loud rusty squeak. Mr. Bad visits the Mayor disguised as a cowboy and lies that there is a large diamond inside Mt. Crumptonville. The Mayor hands him some dynamite to retrieve the diamond, and orders the city to wear earmuffs to protect their ears against the blasting. Eric and the Superchums discover the World's Largest Screwdriver has gone missing and rush to the mountain to stop Mr. Bad. They are too late, but when the screw is turned a giant diamond ring is ejected throwing Mr. Bad and Appliance out to sea.
