Plankton is the tiny, scheming villain from SpongeBob SquarePants, the long-running Nickelodeon cartoon, and his high-pitched voice makes even a simple groan sound dramatic. Clips of his exaggerated ahhhhh have circulated online as a short reaction sound, shared on soundboards and in meme edits where creators need an instant burst of frustration. Like other cartoon scream meme clips, it works because the character is instantly recognisable and the sound needs no context. That simplicity has kept it in regular use for fails, gaming clips and over-the-top reaction videos.
