Totodile look like small, bipedal blue crocodiles with red spines on their back and tail, the one on their back being larger with additional ridges next to the back spines. Totodile's head is large, with crocodilian ridges above its eyes, and much of the head's size is composed of Totodile's snout and strong jaws. There are two visible teeth on the tip of its upper jaw, and two rows of three teeth on each side of its lower jaw. Totodile's mouth is often depicted open. On its chest is a yellow, somewhat V-shaped pattern that extends to Totodile's arms, with a line bisecting the pattern at the middle. Totodile have five sharp claws and three toes. Its eyes have red irises, and there is a dark blue or black pattern around the eyes.
Despite their small size, Totodile are very powerful, especially when underwater. Totodile have a very large set of jaws for a Pokémon its size, just a playful nip can be painful. It can also bite with ice cold fangs.
Totodile have a habit of biting anything they see, including their Trainers. It is unwise to turn one's back on a Totodile. Totodile also have a genuine playfulness about them, they are always ready for a good laugh. There is a tough side to Totodile though, as they can quickly react to difficult situations in a battle and bounce back with boosts of their Water-type moves.
Totodile live close to the water. Being reptilian, they prefer tropical climates and are typically found around large rivers and ocean shores.
Due to their strong jaws and sharp teeth, it is most likely that they are a carnivorous species.
