One of the animatronics the player is up against (she doesn't look like it in the picture, but just trust me on that). She's an eccentric girl with far too much energy, and a can-do attitude. Her lid is also very easy to blow. 

Like the Snarky Young Guy's voice, I don't think I have very much in mind for this character's voice. Something "normal" might be alright. However, for some of her voice clips (like the first two audition lines), I imagine an "evil" or sadistic kind of tone. We won't need this tone too often, though, as it takes up a very small amount of this character's script.

Her speaking lines are very few and far between, actually; the only times she gets to talk are when she talks to the player after killing them a-la Ultimate Custom Night, and during the ending sequence of the game.
