Mr. Krabs is the money-focused crab character from SpongeBob SquarePants, the Nickelodeon animated series that debuted in 1999. His laugh became a familiar reaction sound online because the character is strongly associated with greed, business and exaggerated cartoon humor. Short clips of the laugh spread through meme edits, SpongeBob compilations and reaction videos, where creators use it to underline jokes about profit or opportunism. It remains popular because even a brief laugh immediately evokes the character and the show’s fast, absurd comic style.
