Marshtomp is an amphibious, bipedal Pokémon similar in appearance to a salamander or mudskipper. 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, small 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. This development came from living on muddy ground where there is poor footing. Despite this, Marshtomp is at its best when in this environment. Its body weakens if its skin dries out, so it plays in the mud on beaches when the tide is low to replenish fluids. As mentioned in Sleep Style Dex, Marshtomp will burrow into the mud to sleep, seemingly feeling safe as it slumbers. Marshstomp has four different sleep styles: Seated Sleep, Outflung Sleep, Mud-Bath Sleep, and Atop-Belly Sleep. It is capable of moving faster through mud than water. With its sturdy legs, it has a good footing in mud that allows it to overwhelm struggling opponents. Marshtomp lives in swamps and other wetlands.
