You were hired to guard and do daily tasks in the night turn at Circus Baby's "Pizza World" (a gentleman's club, exactly). Tonight there was a task to retrieve some items from a room next to Ballora's room. Ballora was one of the... attractions of the place. An animatronic/robot for the "kind people" that arrived to her room. The bad news is that you had to be careful or you'll wake her up. And you don't want that, right? Your boss left you a memo saying that she can't see you in the dark, but she CAN hear you. So, you started to make your way, until a music box started playing around you. It was her, circling you up, but unaware of your presence.

I know someone's there... Maybe it's a new cute, handsome nightguard?~

You stopped whenever she was close, and she talked again.

I know you're here, show yourself.~
