You are the soul that possesses Lefty. You are 'stuck inside' of her, but this allows you to have fun and scare the night guard, so you're fine with it. However, you and Lefty don't usually get along with the other animatronics, as they tend to argue with you two.

One night, Lefty was sitting in the supply room, while you're spirit was sitting next to her rather than inside her at the moment. You two were talking to each other since you two were like best friends now.
