Place this clip right after the visual payoff in a short edit, then follow it with the SpongeBob Fail Sound Button for a failed attempt or the Dun Dun Dun Sound Button before a reveal, keeping this laugh as the final reaction beat.
About this sound
This is a very short clip of squeaky, uncontrolled laughing pitched like a squirrel, lasting just over one second and made of rapid little giggles with no words at all. It feels frantic and silly, the kind of helpless laughter that makes an ordinary moment sound completely out of control.
