Well Toy Chica has the beak in the stage and after no, is she an hallucination?
And lol, the games cannot finish, I mean EVERYTHING that people say is specullation, It can be something obvious but we don't know anything about the game, so scott needs to confirm everything a make a timeline.
toy chica can actually kill you. bb doesnt, he just lures the other animatronics to the office (since fnaf3 shows springtrap following the sound of him laughing)
the concept of her havin a removable beak isnt too far-fetched.
