I am Plankton. GIVE ME THE KRABBY PATTY FORMULA, here is my story. Plankton is the nemesis and former best friend of Mr. Krabs.[7] He is the owner of the Chum Bucket, a fast food restaurant located directly across the street from Krabs' restaurant, the Krusty Krab.[8] The Chum Bucket primarily sells chum (bait consisting of fish parts), which is considered mostly inedible by the other characters. As a result, his restaurant is a commercial failure.
