This screech comes from Five Nights at Treasure Island: The Revenge, a fan made horror game in the Five Nights at Freddy's tradition, catalogued under FNaF and FNaTI collections. The character Laila gives a short shout that players associate with sudden encounters in the game, similar in use to a classic FNAF jumpscare scream. Clips from fan games like this circulate in archives and soundboards, where short scare sounds are saved, shared and reused in edits long after the original gameplay moment.
