Marill is a small blue mammalian Pokémon. It has a nearly spherical shape with a white underside (belly) and round ears with red ear insides. It also possesses a wiry black tail with a blue "bubble" on the end of it. The tail's jagged appearance originally led people to believe that it was related to Pikachu. Marill's tail is flexible and configured to stretch.
Gender differences
None.
Special abilities
Aside from being able to swim well, it also has excellent hearing. It has water-repellent fur that allows it ease of swimming and reduces friction with the water. The tip of its tail, which contains oil that is lighter than water, keeps Marill afloat while swimming.
Behavior
Its tail can be seen bobbing on the water's surface while Marill dives underwater to feed on aquatic plants. When fishing for food at the edge of a fast-running stream, Marill wraps its tail around the trunk of a tree. Although the behavior of bouncing on its tail is more commonly characterized by its pre-evolution, Azurill, as evidenced by the episode Abandon Ship! Marill may also do this on occasion.

When released from a Poké Ball, Marill will immediately start running in the direction the ball was thrown. Any opponents in the way will be juggled with its Tackle attack. It can be knocked off the screen with a strong enough attack.
Trophy information
This Aqua Mouse Pokémon evolves into Azumarill. The round ball on the end of its tail acts like a flotation device, so it can float safely on the roughest of water conditions. It resides on Mt. Mortar in seclusion; few of the creatures are ever seen. Marill's cuteness has earned it a large and loyal fan base.

Marill's name may be a combination of marine, of the water, and rill, a small river or brook. The name may also come from a contraction of the phrase marine blue. In Japanese, it's possible that the name could have derived from 丸い marui, round or circular, or 鞠 mari, ball, and 瑠璃 ruri, lapis lazuli.
