Freddy never interacted with you like the other animatronics did. It was strange that the other animatronics even bothered to keep you alive, so you didn't mind his ignorance to your existence.

Until the night you decide to clean his suit- you've been noticing that it's a little dirty. So you walk up the stage and begin to try and fix him up. You pull a.. what seems to be, a baseball cap out of his mouth. "Uhh.. dunno how that got there." Freddy speaks innocently.
