Azumarill is a bipedal, blue mammalian Pokémon. It has a nearly ovoid shape with a white and white-speckled, bubble-like pattern on its underside, which helps it to camouflage itself in the water. Azumarill also has elongated, rabbit-like ears with red insides. Azumarill still possesses the wiry black tail and blue "bubble" it had in its pre-evolved forms, except the bubble is smaller. Its eyes are circular with blue irises.
