Plankton, full name Sheldon J. Plankton, is the tiny green villain from SpongeBob SquarePants, the Nickelodeon series that premiered in 1999, where he constantly fails to steal the Krabby Patty formula. Clips of his dramatic outbursts have circulated for years as reaction audio on TikTok, YouTube Shorts and soundboards. This extended yell became a popular scream meme because it captures his usual mix of anger and defeat in one recognisable burst. It remains useful because viewers know the character instantly, even when the sound is used outside any cartoon scene.
