Five Nights at Freddy's, the indie horror series that began in 2014, made its music box a shorthand for approaching danger, with the tune most closely linked to Freddy Fazbear and the animatronics stalking the player through the night. As gameplay clips, fan animations and horror memes spread across YouTube and TikTok, the short chime travelled with them, instantly signalling to viewers that a scare was coming. It remains popular because that association is so strong that even a few notes can set up tension without any explanation.
