Why is Nightmare Chica's eyes orange, and no pupils?
Balloon boy has is hollow
Pig has different eye colours
Why is there a bucket with 1 dilated eye, a cage with no smile and nothing to hold, and a balloon with a drawn smile?
Why does golden freddy have wires coming out of his eye socket, and why is there green on his head
Why is lefty missing his left eye
Why does foxy have a parrot, and they both have the same eye patch placement (right eye)
Why is there 2 toys of each main character except foxy?
Between foxy and mangle, only one can be chosen per form (1 original foxy, then 1 toy mangle, then 1 nightmare mangle, then 1 toy foxy)
Why do foxy and mangle have the same eye colour, and animal?
Why is ennard using a party hat?
Mini theory: There are 2 toy chains, one has foxy and the other has mangle, maybe the one that has mangle is the one truly intending to hurt, as mangle was the nightmare one. Also the toy series that has mangle seems to be trying mainly to be happy, while the other has different emotions
