Azurill is a round, blue mouse Pokémon. It has circular ears with pink insides. There are two white dots on its cheeks, and it has black eyes. Its thin, black, zigzagging tail has a large blue ball at the end. The ball is bouncy and packed with the nutrients it needs to be able to grow. The ball can also be used as a flotation device. It can be seen bouncing and playing on this rubbery tail. The tail can also be spun around like a lasso. When the tail is thrown, the body can go as far as 33 feet (10 meters). It uses its tail for fighting opponents bigger than itself. It lives at the water's edge.
