Wigglytuff is a balloon-like Pokémon with leporine features, a bean-shaped body and stubby arms and legs. There is a fluffy, curled tuft of fur on its head, which is described as perfectly heavenly. It has long, rabbit-like ears with black insides and slightly lighter color at the tips. Its large, blue eyes are covered in a layer of tears that quickly washes away any 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 in total. While it is inflated, it is able to move by bouncing or floating. It competes with other Wigglytuff to see which one can inflate itself the most. Should it be caught in a bad mood, Wigglytuff will inflate itself to an enormous size in order to scare away its opponent. Being the result of an evolution via Evolution stone, Wigglytuff is rarely found in the wild, though they can be found in vivid green plains and grassy fields.
