Plankton is the scheming, one-eyed villain from SpongeBob SquarePants, the long-running Nickelodeon animated series, and his exaggerated panic fits the show's cartoon style perfectly. Short clips of his voice have circulated widely on meme soundboards and in short-form video edits, where the tiny character's outsized reaction is used as a quick shorthand for defeat, fear and overreaction. As a scream meme, it keeps working because it is instantly recognisable, easy to drop over a fail and funny precisely because the threat is rarely as serious as Plankton makes it sound.
