Place it at the reveal cut in a gameplay edit, after a dramatic dun dun dun sound builds the setup and before a Fortnite death sound effect marks the failed attempt, so the scare stays the peak moment between them.
About this sound
This is a 1.5-second harsh, distorted burst that plays when Plushtrap lunges at the player. It feels startling and threatening, turning a quiet moment tense in an instant with its abrasive attack. The clip comes from Five Nights at Freddy's 4, from the Fun with Plushtrap challenge in the 2015 game.
