SpongeBob and Squidward work as employees at a restaurant called the Krusty Krab in the underwater town of Bikini Bottom. The Krusty Krab, which is run by a greedy crab named Mr. Krabs, is famous for its Krabby Patty burgers. The recipe for Krabby Patties is top secret. The owners of a competing restaurant called the Chum Bucket, Plankton and Karen, often try to steal the recipe.
