Place it at the end of a short setup, after the joke is clear, so the gag lands as the punchline. Lead in with the Classic Fart Sound, then follow it with the Vine Boom Sound for a bigger reaction.

This is a short squealing poop sound effect lasting about 3.7 seconds, turning a bathroom gag into a sharp, cartoonish squeak. It feels gross, silly and deliberately juvenile, the kind of noise that gets a laugh and a cringe in the same moment. It lands best as a sudden punchline, not as something to leave running in the background.
