Swoobat is a primarily cobalt (teal in the anime), batlike Pokémon. Its pointed ears, with lighter-colored insides, are attached and thus resemble the triangular shape of a metronome. The large pink snouts of Swoobat sport a single, heart-shaped nostril, and the mouth is wide and toothed. A mane of white fur covers its neck and body. It black, batlike wings have 'thumbs', and its lower limbs are also black-colored. The lowermost segment of its body is blue, and its bare, pink, ratlike tail has prongs at the tip that may be described to form a heart shape. It also has three-toed feet extending from the underneath its mane.
