About Five Nights At Freddy's 2

Towards the Destroyed Animatronics of Freddy's 1.

1 - Probably they belonged to some other company as mascots who ran out of business due to bankruptcy and were bought as ideas to study and create NEW animatronics all along.
2 - The fact is heavily reinforced because they look terribly fucked up, Bonnie doesn't even have a face, which I guess made the designers for the Toy animatronics to make Toy Bonnie the way he is out of pure creativity, I think the old ones were bought as a manner of studying for creating the true animatronics. But well, they didn't knew the shit they were going for.
3 - Their redesign plays a huge roll as you can see they look totally different in Freddy's 1. More friendly, less fucked up than in Freddy's 2.

Towards the Bite of 87.

1 - There's a killer who use a costume of Golden Freddy, which explains the imagery of the Animatronic Skeleton and the fact Golden Freddy has no fucking eyes.
2 - He kidnaps 2 to 4 kids. As that, either Toy Bonnie or Mangle have some sort of face recognition system that captures the killer, all animatronics have this.
3 - When the bastard goes to hunt the 5th kid, Mangle does the bite on the Killer, which scares the owners of Fazbear Pizza, decomissioning Mangle, destroying her, which ends up having her in the roll call as a destroyed animatronic.

Towards the game's ending.

FUCKING SPOILERS

1 - As you get your check, you see clear as day the date of the check, 1987. Goddamn, if this isn't a prequel, then I'm Jesus incarnate.
2 - The news journals all around the check suggest clear as day that the building you work on will close, with a big budget cut and with big hopes of striking again big time. Which matches perfectly what Freddy's 1 description of the restaurant sounds like.
3 - Having no doors seemed fresh as an Idea at first, but when I mashed the potatoes togheter, I noticed that they arranged many things as a prequel, and it is a very subtle and very well put one. Good work mister Scott.
