Place it right on the punchline beat, then follow it with Vine Boom to underline the reveal and keep the edit moving. For a failed joke, put SpongeBob Fail just before it so the miss sets up the reaction, then let it close the moment.
About this sound
Kaa is a roughly five-second vocal clip built around a single clipped utterance that lands fast and cuts through a scene. It feels abrupt and funny, like a tiny interruption that makes a reveal or an awkward pause hit harder. The sound stays simple and low-context, so it works as a quick reaction beat in short edits without needing any setup or explanation.
