Cyndaquil is small, bipedal Pokémon with bluish fur on top of its body, and a milky colour on the underside. Although called the Fire Mouse Pokémon, Cyndaquil seems to be a composite of features from the echidna, seen in the flames erupting from its back, and the shrew, the general shape of its body. Its eyes are often closed, as it is still young. It has four red-colored spots on its back from which its flames erupt. It lacks claws on its forelimbs, but has a single claw on each hind foot.
