Put this clip just before the reveal in your edit, then follow it with the dramatic dun dun dun for the fallout and the MLG air horn for the punchline after the chaos lands.

This 3.9-second clip is a standalone siren effect built around a loud, sustained emergency wail. It feels tense and urgent, as if something has just gone wrong and needs attention right away, and its sharp tone is strong enough to cut through music or talking. It works as a quick warning rather than long background noise.
