Marshtomp

“The surface of MARSHTOMP’s body is enveloped by a thin, sticky film that enables it to live on land. This POKéMON plays in mud on beaches when the ocean tide is low.”

— Pokémon Ruby

“MARSHTOMP is much faster at traveling through mud than it is at swimming. This POKéMON’s hindquarters exhibit obvious development, giving it the ability to walk on just its hind legs.”

— Pokémon Sapphire

“Its toughened hind legs enable it to stand upright. Because it weakens if its skin dries out, it replenishes fluids by playing in mud.”

— Pokémon Emerald
