Five Nights at Freddy's, Scott Cawthon's 2014 indie horror game, made its end-of-night music-box chime iconic among horror fans. After each survived night, a short, warped melody plays over the paycheck screen, rewarding players before the next, harder shift. Clips of that moment circulated on YouTube and TikTok as the series exploded into a franchise of sequels, books and a 2023 film. Editors now lift the jingle to end videos, because even eight seconds of it tells viewers something unsettling just happened.
