Plankton, full name Sheldon J. Plankton, is the tiny villain from SpongeBob SquarePants, the Nickelodeon cartoon that premiered in 1999 and follows his endless failed attempts to steal the Krabby Patty formula. Short clips of his frustrated reactions have circulated widely on soundboards and in meme edits, where a single groan can stand in for any scheme going wrong. The augh clip stays popular because Plankton's over the top disappointment is familiar to generations of viewers and instantly recognisable even out of context.
