Sorry, need to continue this: XD

Maybe Burgerpants can be Withered Bonnie? I mean, it WOULD make some sense for him to be jealous of Toy Bonnie then.

The Nicecream guy could be Lolbit, or Medo? As they are vendors...

Monster Kid could be The Crying Child from FNAF 4, (striped shirt) and Gaster could be Shadow Freddy?

Perhaps the most influential is this.

Asriel Dreemur could be Golden Freddy, the battle version could be Withered Goldie, and the Absolute God of Hyperdeath would be like....Nightmare Golden Freddy....

And...perhaps The dog squad could be some of the foxes? Like, Doggo is Withered Foxy (I can only see DARK objects...) Greater Dog can be Nightmare Foxy, Lesser Dog could be Phantom Foxy, and just for kicks, we could have The Dogi (Dogamy and the other one [I'm awful at remembering names.]) Could be Funtime Foxy and Pre-FNAF 2 Foxy? I dunno. Some ideas.
