Place this clip second in a scare sequence, after an enemy spotted cue and before the reaction beat, then follow it with a FNAF jumpscare scream for a bigger payoff or a Roblox oof if the victim's reaction is the punchline.
O tym dźwięku
A very short clip of the Pyro from Team Fortress 2 letting out a muffled 'boo' through the gas mask, lasting about a second and a half. The muffled delivery turns a simple scare into something silly and teasing, more startle-prank than horror, which is why it reads as playful mock-menace rather than a real fright.
