Springtrap - Shadow Bonnie or Springtrap? (read desc.)

But Shadow Bonnie looks exactly like Toy Bonnie except for the teeth (and the color obviously).

I don't know why people come to think of that this is the new Animatronic from FNaF3. I mean, it looks nothing like it, except for the teeth maybe.

But Shadow Bonnie has much puffier cheeks.
