Where did the carnival thing come from? Because I think that wouldn't make any sense considering that a bunch of unanswered questions lie in Fredbear's Diner.
1. What is the puppet, and where did it come from?
2. Why is it able to control other animatronics?
3. Why does it make the animatronics exclusively target night-gaurds and staff?
If there was another game, and it answered these questions, then Scott will be a god of indie game storytelling.
