The music box is a recurring motif in Five Nights at Freddy's, the indie horror game series where cheerful animatronic characters become a threat after dark. A gentle, toy-like tune that should feel comforting instead signals that something is watching, and that contrast made the sound instantly recognisable to fans. Clips of it spread through gameplay videos, fan edits and short-form memes, where creators reuse the chime to hint at danger without showing it, keeping it popular long after players first heard it in game.
