Azumarill

Azumarill (Japanese: マリルリ Marilli) is a -type Pokémon introduced in Generation II.

Appearance
Azumarill's physical appearance includes two large, floppy ears. It's blue on the upper half, and white on the lower half. In the middle are white circles of various sizes. Azumarills have short, stubby, blue arms with no fingers. One significant feature is its zigzag tail with a blue ball at the end, which is a trademark to one of Azumarill's pre-evolution, Azurill.

Evolution
Azumarill evolves from Marill at level 18. It is the final evolution of Azurill.

Trivia

 * Lady Azumarill is a friend of the Pichu brothers.
 * In Pokémon Mystery Dungeon Explorers of Time, Darkness, and Sky, after Azurill and Marill leave the Kecleon Store for the first time (on-screen), Kecleon explains that their mother has sadly grown ill, which explains why they are doing the shopping. It is possible that their mother is, of course, an Azumarill.
 * Azumarill's name is a mix of it's previous evolutions, Azurill and Marill.
 * Black 2 and White 2 are the only games to have an underleved Azumarill.
