Full name of Mr. Krabs' nemesis Plankton on "Spongebob Squarepants" who works at the Chum Bucket. He frequently tries to steal the Krabby Patty secret formula, but also frequently fails. The closest he got to the recipe was the recently new epsiode entitled, "Plankton's Army" (Where his full name was also revealed).
Haha! Sheldon Plankton! What a funny name...
