These are just some things I noticed about the FNAF 3 trailer, these aren't confirmed facts.
Could Shadow Bonnie be Golden Bonnie?
All of us FNAF fans know there's going to be a third game, and in the trailer there seems to be Golden Freddy, but as Bonnie. After watching this, I couldn't get this out of my head. I soon realized the similarities between Golden and Shadow Bonnie. You see, the eyes of Shadow Bonnie are bigger than the other animatronic eyes, and the eyes of Golden Bonnie are more exposed than they should be. Adding to that, the teeth are extremely similar. If you notice any more, please add them in the comments. Thanks for reading!
