His right hand is missing the skin, revealing the endoskeleton hand. His right foot is also missing the skin. He has holes all over his body and wires poking out. He now has two buttons on his chest. Both of his ears remain. he has two red eyes that identify the locations of his costume eyes, which have disappeared with his face.
Bonnie is easy to handle if you see it on the camera in the Left Air Vent but on later nights you will have to put the mask on every time you put the monitor down.
