I think the level should be like this: Somebody has abducted some of the animatronics (any animatronics accept for Freddy, Foxy, Bonnie or Chica, because they would be playable), so it's up to the 4 animatronics to get the rest of the animatronics back. The bosses could be Golden Freddy, Nightmare, & the final boss, Purple Guy. Also, Purple Guy would be the person stealing animatronics.
