The sound comes from Five Nights at Freddy's, the 2014 indie horror game by Scott Cawthon, where running out of power leaves the player defenceless as Freddy plays his music box tune. Clips of that moment spread widely through gameplay videos and fan remixes on YouTube, and creators began extending the short jingle into longer remix versions like this one. It is now often paired with a FNAF jumpscare scream for edits and memes, and remains popular because anyone who played the game instantly recognises the danger it signals.
