Mudkip (Japanese: %u30DF%u30BA%u30B4%u30ED%
u30A6 Mizugorou) is a Water-type Pokémon.

It evolves into Marshtomp starting at level 16, who evolves into Swampert starting at level 36.

Along with Treecko and Torchic, it is one of three starter Pokémon that can be chosen at the beginning of Pokémon Ruby, Sapphire, and Emerald.

Physiology
Mudkip are small blue Pokémon with large heads with orange external gills. They also have a fin on the top of their heads and a light-blue fin for a tail. They move around on all four legs.

Gender differences
None.

Special abilities
Mudkip can use the fin on their heads to detect subtle changes in air and water currents, and can detect nearby bodies of water in this way. They can also detect danger. Like most water Pokémon, Mudkip can shoot water from their mouths. When in water, Mudkip breathe using the gills on their cheeks. On land, they can powerfully lift large boulders by planting their four feet and heaving. They sleep by burying themselves in soil at the water's edge. Their large tail fin propels them through water with powerful acceleration. If they are faced with a tight situation in battle, Mudkip will become strong enough to crush rocks bigger than themselves.

Behavior
Mudkip are more mellow than their evolutions, but are protective of their kind and because of their powerful strength they group up in numbers and easy overpower their foes.

Habitat

Water's-edge PokémonMudkip and members of its evolution family dwell in swamps or other wetlands, deep inside isolated islands, because of their dislike of fresh water lakes and ponds. Soon after birth on beautiful beaches, they swim to swamps deep within islands. Very few have been known to hatch in swamps.

In the Manga
In Pokémon Special, When Ruby was attacked by Sapphire's Torchic, Professor Birch told him to look in his briefcase, to pick up the Poké Ball with a blue Pokémon and to throw it. The Poké Ball released a Mudkip and he nicknamed it Zuzu. At the beginning Ruby was dissaponted with it because it wasn't pretty enough like his other Pokémon and it couldn't particpate in any Pokémon Contest. He tried with different conditions and then he decided that Tough Contests would be perfect for it. Zuzu eventually evolved into a Marshtomp and then into a Swampert.

In the manga Pokémon Mystery Dungeon: Ginji's Rescue Team, Ginji's partner and first friend is a cautious Mudkip.
