The Croc is a giant female crocodile in Fox's Peter Pan & the Pirates.
Peter Pan fed Captain Hook's hand to the crocodile when he assumed that she had eaten Tootles and Nibs while they were captured by the pirates. The crocodile has the only clock in Neverland inside of her which controls the time of day.
Unlike in most adaptions where the crocodile exclusively targets Captain Hook, she tries to eat anyone within her reach, regardless of who the person may be.
For some reason her teeth are square like human teeth, and she has a gold tooth.
