Wigglytuff resembles a pink blob with stubby arms and legs. There is a fluffy, curled tuft of fur on its head, and it has long, rabbit-like ears and large, blue eyes. A layer of tears covers its eyes, quickly washing away any debris. It is covered in pink fur with a white underbelly and ear tips. This fine layer of fur is so soft that those who touch it, including other Wigglytuff, will not want to stop. Its body is soft and rubbery, allowing it to inflate by inhaling.
Wigglytuff can inflate itself up to 20 times larger. 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. Wigglytuff can be found in vivid green plains and grassy fields.
Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness and Explorers of Sky: Wigglytuff is the head of the main guild in Treasure Town. His personality tends to be erratic, but he cares about all his friends in the guild, especially his close partner Chatot. He also has a love (some would say obsession) of Perfect Apples, and is basically all he eats. He can often be seen bouncing one off his head during dinner. He is described as peculiar and weird in the game, although he is exceptionally strong, defeating the whole of Team Skull and Kabutops and the Omastar Brothers, as well as numerous others, with ease. Chatot warns not to annoy or disrespect Wigglytuff, as he is liable to explode with anger.
Wigglytuff has the highest base HP of all Fairy-type Pokémon.
In its earlier appearances, Wigglytuff's white stomach did not always extend above its mouth; however, it always does this in modern appearances.
Wigglytuff appears to be based on a balloon. Its ears resemble that of a rabbit.
Wigglytuff's name is a combination of wiggly and tuff, referring to its wobbly shape and either its toughness or the tuft of hair on its head.
