The sound comes from Five Nights at Freddy's 3, the third game in Scott Cawthon's Five Nights at Freddy's horror series, released in 2015. The Puppet, a character first introduced in the second game, is closely linked to a winding music box, and its quiet, unsettling melody became one of the series' most recognisable audio cues. Fans clipped the theme for YouTube lore videos, horror edits and TikTok, where it now signals an approaching threat even outside the games. Its soft sound makes the tension feel more personal than a loud jumpscare.
