Croconaw is the evolved form of Totodile. It has 48 fangs in its mouth. When it bites something, it never lets go until it loses a fang. Despite its size, I would expect a tough voice, since it looks like it has a tough personality.

Feraligatr is the final evolution of Totodile. Once it opens its large mouth and shows its fangs, it is intimidating its foe. Usually it moves slowly, but moves at a blinding speed if trying to catch prey. It can tear up the victim when biting with its powerful jaws and shaking its head. As it gets to the final evolution it would have a more huskier sounding voice compared to Croconaw.
