I always thought Freddy's handprints came from Phone Guy.

That, and the fact that there's far more evidence pointing to Mangle doing the bite of 87.

If the withered animatronics did it, why repair them? If a Toy did the bite, they'd have a reason to both scrap the new ones and use the old ones again.
