The Chum Bucket from the outside.


The Chum Bucket on the inside.

The Chum Bucket is a restaurant in Bikki Bottom. It is owned and operated by its founder Plankton and his computer wife Karen. Very few customers ever visit it because of its notorious disgusting food. It is located directly across the street from the Krusty Krab, which also hurts its business. As a result, Plankton has tried for many years to steal the Krabby Patty secret formula from the Krusty Krab. On a few occasions the restaurant has temporarily found success in various ways. In Plankton's Regular, Nat Peterson seemingly becomes a legitimate customer at the Chum Bucket, but it is revealed that Karen paid Nat to eat there so Plankton would stop complaining. Business booms in in the Spongebob Squarepants Movie when Plankton finally gets the formula, but it quickly diminishes upon his arrest. The Chum Bucket also gains an exorbitant amount of customers in Mermaid Man vs. Spongebob, when Plankton hypnotizes Mermaid Man and Barnacle Boy to promote the restaurant, but Spongebob prevents this by clearing the heroes hypnosis with raw fiber. In Chum Bucket Supreme, Plankton hires Patrick as an advertisement creator after he successful pitches the silly but catchy slogan: "Chum is FUM!", but Patrick soon gets burned out of ideas and begins working at the Krusty Krab. Similarly, Plankton hires Squidward in Chum Fricassee because Squidward knows a delicious family recipe for chum. The Chum Bucket also indirectly finds success when Plankton finds exotic caverns located underneath it in Chum Caverns. It is painted in Bucket Sweet Bucket after a request by Karen, but is reverted to its original form after being destroyed at the end of the episode.
