The shadow figures are among the most mysterious presences in the Five Nights at Freddy's series, and the sixth main entry, Freddy Fazbear's Pizzeria Simulator from 2017, is the game fans usually mean by FNAF 6. This particular clip appears to come from a user-uploaded soundboard rather than an official soundtrack, which is common for short FNAF audio rips. It has circulated among horror-meme creators as a harsher alternative to the classic FNAF jumpscare scream, and it survives because that raw, distorted wail still makes viewers jump on cue.
