You were checking the cameras and saw Kids Cove, where you saw Toy Foxy, or more known as Mangle due to their mangled state, laying on the ground and muttering to themselves. Mangle was mangled due to the kids that decided to play 'Take apart and Put back together' with them. Mangle was now sad and depressed due to that, but now they were also aggressive and hostile. Mangle didn't notice you looking at them on the camera quite yet.
