This sound is most closely associated with Freddy Fazbear in the original Five Nights at Freddy's, where a music box style version of the Toreador Song became one of the game's most recognizable audio cues. As FNAF videos, theories and reaction clips spread online, the tune turned into a shorthand for incoming danger and late-night panic. It still shows up in horror memes and is often paired with a FNAF Jumpscare Scream to escalate a scene from eerie to chaotic.
