List of characters

Sheldon J. Plankton, more commonly known as Mr. Plankton, is the owner of the Krusty Krab in "The Algae's Always Greener." He appeared when Plankton and Mr. Krabs switch lives. He is the same as the regular Plankton. The only difference he has from the real Plankton is that he has clothes exactly like Mr. Krabs.


  • In this Universe, Plankton is wearing clothes and Mr. Krabs is not wearing any clothes.
  • It is possible that technically, the main universe Plankton also switched lives with the Actual Mr. Plankton meaning that Plankton and Mr. Plankton have also switched souls making the actual Mr. Plankton getting the Main Universe Plankton's Body in the Main Universe for a while since there was a picture of Mr. Plankton and Alternate Universe Pearl as a memory, for example.
