The Evil Turtle is likely an African softshell, the only living member of the Trionyx genus. She has a long, wrinkly neck and a small, protuding snout. Her carapace and head are olive in coloration, while her plastron is mint. Darwin notes that she smells "like a belly button."
She focuses all of her efforts into biting people. She is also practically invincible, being able to survive a direct hit from a car and leave an explosion unscathed.
