Marill, the Water Mouse Pokémon. Its sensitive ears can detect distant sounds and the round rubbery tip on its tail can expand and contract, assisting Marill in the water.
Cool facts about Marill:
- Its arms and feet are short and possess no visible digits.
- There is a blue, bubble-like ball at the tip of its zigzagging black tail that is full of oil. The oil is lighter than water, and keeps Marill afloat in the water.
