The Music Box is a returning feature from Five Nights At Freddy's 2. The player must wind it up so the music box doesn't go off and the Marionette doesn't get hostile. This game mechanic is used with Chica as well.
Ultimate Custom Night
The Marionette
It bears the same mechanics in using the music box from the second game, winding it up so the Puppet cannot go hostile and cannot attack the player, if the player dosen't wind up the music box, the Puppet will play a jingle and attacks the player, ending the night run. If the player uses a Death Coin in the kitchen when Marionette is active, the Music Box will instantly go up since Marionette is gone.
Chica
Chica can be affected with the music box, as a different mechanic, if the player hears pots and pans falling off making noise, she is neutral, she gets agitated if the same music repeats over and over, and if she stops making noise the player needs to go to the Kitchen camera and change the music time fashion before she gets out of the Kitchen and jumpscares the player, ending the night's run.
