Lore

Ruby
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.

Sapphire
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.
