Sheldon J. Plankton commonly known as Mr. Plankton is the version of Sheldon J. Plankton in the Mr. Plankton Universe. Unlike the main timeline of the show he is successful and owns the Krusty Krab. In this timeline, it can be reasonably assumed that in "Friend or Foe" he gets the Krabby Patty Secret Formula while Krabs gets the chum formula instead. Mr. Plankton only appears in the episode "The Algae's Always Greener."


He looks exactly like Plankton, but he wears Mr. Krabs' outfit.

Role in episode

He only appears in a picture with his daughter, Pearl. The rest of the episode has Plankton take his place.
