Feral Ann acts a lot like a feral wild animal, even to the point of resembling prehistoric human behaviors, hence her nickname. She can be seen often climbing trees, swinging on vines, and capturing animals. She can speak English but very, very barely. One of her only lines was "Rub, rub, rub!" when she wanted Banana to rub her feet (which were very dirty since she obviously lacks hygiene.) This caused her to quickly fall asleep. She seems to have a large disliking for her prey to attempt to escape.
Feral Ann has pale skin, red-orange hair and several buck teeth. Her hair has a few bones holding its place, which further represents the prehistoric stereotype. She is usually seen smiling with rosy cheeks and standing with her back hunched over. She wears a long yellow dress (likely made from cheetah fur) and black boots.
