Nightmare Bonnie is one of the twisted animatronics from Five Nights at Freddy's 4, released in 2015, where players must survive nights in a child's bedroom while the nightmares hunt them. The jumpscare plays when Bonnie reaches the player, ending the night in a sudden scare. Clips of that moment spread through YouTube playthroughs, TikTok edits and fan soundboards, where the audio was separated from the game and reused on its own. Like the classic FNAF jumpscare scream, it remains popular because it instantly signals horror, danger and a failed run to fans who recognise the franchise.
