Place it at the end of a slow build-up, after a danger alarm cue and before a second scare, so the edit escalates instead of peaking too early. Follow it with the FNAF jumpscare scream for a bigger reaction, then cut to a quiet reaction shot.
About this sound
This 3.4-second jumpscare clip is a sudden, jarring burst of sound built to catch a listener off guard, with an unsettling energy that makes it feel like something has just lunged into view. It is startling and tense rather than playful, creating a quick jolt of alarm. It comes from the Baldi's Basics Character Calamity Series, where it is used as Mr. NiceNasty Guy's jumpscare.
