Plankton, full name Sheldon J. Plankton, is the tiny villain from SpongeBob SquarePants who constantly schemes to steal the Krabby Patty secret formula. Online, fans turned his exaggerated expressions and shrill voice into meme edits, with ugly or distorted versions of the character spreading through TikTok and soundboard communities. Loud re-uploads like this one strip the joke down to pure impact, making the clip easy to reuse across reaction videos, edits and memes long after the original post has faded.
