imagine you you set all the animatronics' difficulty to extreme, and you check the parts and service cam (cam 05), and suddenly the endo is coming for you, too. it can come down both halls, and depending on the hall act like either Bonnie or Chica. or maybe it could come out and then get shoved into a suit of one of the 4 animatronics by one of the animatronics. i doubt this would be added as you're working on a fnaf 2 map and a lot of other things, but it would be cool.
