Withered chica.

Withered Chica's appearance is almost identical to Chica's appearance from the second game of the core series but smaller. Her jaw is completely unhinged and her arms appear to be permanently outstretched. Her hands are missing entirely, with wires protruding from her wrist stumps. There's also a lack of toe nails from Chica's feet.
 * Unlike the other withered animatronics, only Withered Chica's main parts are broken and/or lost, while the other parts appear undamaged.
 * When battling Withered Chica, her bib is switched. This is due to the battle sprite being flipped so a new one would not have to be made.
 * This also happens to Nightmare Chica and Phantom Chica.
 * Despite having an unhinged jaw, she appears to have a "Bite" attack.
 * When attacking, her eyes appear to change in size.
 * Her loading screen is based on her appearance.
