This clip comes from Five Nights at Freddy's 2, the 2014 horror game by Scott Cawthon. Players know it as the music box linked to the Puppet mechanic, which made the tune memorable far beyond the game itself. Over time, it spread through YouTube, TikTok, and short gaming edits as a shorthand for looming danger, especially in FNAF content. It is still widely used because the melody is instantly recognizable to fans and creates tension without needing a jump scare.
