Sheldon J. Plankton, more commonly known only as Plankton, is a green planktonic copepod who is Mr. Krabs' business rival. He runs an unsuccessful restaurant called the Chum Bucket alongside Karen, a waterproof supercomputer who is his sidekick and wife. The Chum Bucket is extremely unpopular in Bikini Bottom because it serves chum, a type of bait made from fish meat.
