Cyndaquil is a small, bipedal Pokémon with bluish fur on top of its body, and a milky color on the underside. Cyndaquil seems to be a composite of features from the echidna and the shrew. The echidna features are the flames from its back, while its general body shape is shrew-like. Its eyes are often closed and it has a long, thin snout. It lacks claws on its forelimbs, but has a single claw on each hind foot. Cyndaquil is usually timid by nature and often curls into a ball when intimidated. It has four red spots on its back from which its flames erupt. Cyndaquil is capable of defending itself using these flames. The fire grows more powerful as Cyndaquil becomes more angry or defensive.
