Listed as part of the FNAAB3 demo, this scream belongs to Nightmare Withered AnomalyBot, a withered animatronic variant designed for horror gameplay. Its sound follows the same tradition as the FNAF jumpscare scream, using a loud distorted shriek to punish a missed cue or trigger a game over moment. Clips from demos spread quickly among fan game players who record reactions and edits, and this one has stayed in use because the timbre is instantly recognisable, abrasive enough to startle even when viewers expect a scare coming.
