Okay, so I do follow up on FNAF things such as gameplay by Markiplier, and TheGameTheorists' theories (even though the FNAF4 theory was so out there and incorrect- sorry MatPat, you missed key details and possibilities), and there's one thing that people have gone to assume: People assume that in the fourth game, the Bite of 87 was shown. That is not at all the case, or at least from what evidence shows. As Markiplier (I believe) has pointed out, something on the TV in the Atari-like mini games shows the year in the early 80s (1983, 1984). Therefore, the sequence of the child's head getting stuffed into Fredbear's jaws was not the infamous "Bite of '87" event. You have to pay close attention and find key details and Easter eggs to truly get an accurate theory or grasp of the games' true lore.

That is all. :>
