The Global Music Box is a mechanic in the Ultimate Custom Night. It consumes extra power, but calms down The Puppet, Lefty, and Chica. The Global Music Box plays the music currently playing in the room Camera 4 is stationed. The music can be heard from the office. The player can activate the Global Music Box by pressing the "5" Hotkey. In addition to calming animatronics, it will wind up the Music Box at the rate of which it depletes, making it useful for minimalizing Camera time.
