I was looking at phone guys transcripts for night 1 on the first FNAF game and well, he talked about how animatronics used to walk around until the bite happened. It has me wondering, was it really fredbear that caused it?
...no, it was Mangle. Fredbears family diner was closed by then, probably
It wasn't confirmed it was mangle, although it does seem like a good idea with her broken jaw
What do you think?
