Place it at the end of a scene, right after the final line and just before the cut to black. Follow it with the Vine Boom sound for a second beat, or lead into it with the Metal Pipe Clang, then let the next scene start clean.

This is a short, sharp slam from the Hanna-Barbera cartoon sound library, built around a heavy impact that lands in just over a second. It feels abrupt and comic, like a door shutting hard in the middle of a scene, with a burst of cartoon energy that makes a cut feel sudden and final. It comes from the classic Hanna-Barbera effects used across the studio's animated shows.
