I have a theory for all fnaf games. As we know purple guy is spring trap ,so we know who springtrap is. But how would the fnaf 2 and 1 animatronics be haunted. As in the minigames after completing a night we see purple guy breaking the animatronics. And in night 5 he dies. But in the minigame old bonnie is blue, and in the second game withered bonnie is blue. So and phone guy mentions a freddy fazbears pizza left to rot before fnaf 2. And we know it isn't fredbears diner, because there was only 2 animatronics in fredbears diner, golden freddy and springtrap, so we know there is four freddy fazbears buildings. And fnaf 2 is after the one left
