Marshtomp (Japanese: ヌマクロー Numacraw) is a dual-type Water/Ground Pokémon.

It evolves from Mudkip starting at level 16 and evolves into Swampert starting at level 36.


Marshtomp is an amphibious bipedal Pokémon. Its body is primarily light-blue with a lighter shade of blue for its underside and an orange belly. Marshtomp's head has an angular black fin, orange eyes, and orange gills on the ends of both cheeks. It has long arms with three-fingered hands. Its feet have three small toes, and it has two black fins for tails. This Pokémon has a thin, sticky film enveloping its body that enables it to live on land. Its body weakens if its skin dries out, so it plays in the mud on beaches when the tide is low to replenish fluids. It is capable of moving faster through mud than water. With its sturdy legs, it has good footing in mud that allows it to overwhelm struggling opponents. As its former signature move, Muddy Water is another special capability of this Pokémon. Marshtomp lives in swamps and other wetlands.
