Place it just before the reveal in a short edit, after Dun Dun Dun sets up the reveal and before Vine Boom lands the punch. That order keeps the snake moment as the turning point, with the first sound preparing the viewer and the second sound paying it off.

This is a very short Python clip, lasting just 0.72 seconds, built around a single sharp snake-like sound that arrives and ends almost at once. It feels tense and a little startling, the kind of quick jolt that makes a listener look up before they have time to laugh. Its brevity keeps the focus on that one sudden moment, with nothing extra to soften it.
