Igglybuff is a small, bipedal balloon-like Pokémon that is completely pink. Its body can change to deep pink when the temperature increases. It has a rounded tuft of hair on top of its head, a small swirl-like pattern on its forehead, and red eyes. Igglybuff has small, stubby limbs. This small Pokémon is extremely elastic and can bounce like a ball, although it may not be able to stop if it does this.
It smells sweet to calm the emotions of its foes. Although it has singing abilities, it is not able to sing for long periods due to its underdeveloped vocal cords. It often gets a sore throat from singing too frequently. Igglybuff tend to live in the grasslands close by freshwater streams. It uses water from the streams to gargle in its sore throat.
Instead of walking with its short legs, it moves around by bouncing on its soft, tender body.
