Wigglytuff is a balloon-like Pokémon with leporine features, a bean-shaped body and stubby arms and legs. A fluffy, curled tuft of fur on its head is described as perfectly heavenly. It has long, rabbit-like ears with black insides and a slightly lighter color at the tips. Its large, blue eyes are covered in tears that quickly wash away debris. It is covered in pink fur with a white belly. This fine layer of fur is so soft that those who touch it, including other Wigglytuff, will not want to stop. As a result, Wigglytuff is a highly sought-after Pokémon because of its bouncy body and fur. It sheds seasonally, and people gather the fur to spin into yarn. It is proud of its fine and delicate fur.

Its body is soft and rubbery, allowing it to inflate by inhaling. Wigglytuff can inflate itself up to 20 times larger, though it has no limits to how far it can inflate. While it is inflated, it can move by bouncing or floating. It competes with other Wigglytuff to see which can inflate itself the most. Should it be caught in a bad mood, Wigglytuff will inflate itself to an enormous size to scare away its opponent. Due to evolving via Evolution stone, Wigglytuff is rarely found in the wild. However, they can be found in vivid green plains and grassy fields. As mentioned in Pokémon Sleep, Wigglytuff is known to stroke its belly while sleeping, possibly to feel its soft fur.
