Five Nights at Freddy's, released in 2014, tasks players with surviving a night shift from midnight to 6 AM while animatronic characters roam the restaurant. Reaching 6 AM ends the night, and the cheerful chime that follows became one of the series' most recognisable audio cues. As playthroughs, animations and memes spread across YouTube and later TikTok, the sound moved beyond horror fans and became shorthand for making it through something difficult. It remains popular because that contrast between fear and morning relief is instantly understood, even by viewers who have never played the game.
