The sound comes from the Five Nights at Freddy's series, where the Marionette, also called the Puppet, is a tall animatronic known for its music box mechanic in Five Nights at Freddy's 2. Its scare noise became a staple in fan made games like Fazbear Tycoon and in horror edits shared online. Creators often pair it with the FNAF jumpscare scream for a bigger hit, and the short length makes it easy to reuse across memes, streams and Halloween videos without losing its shock value.
