Marshstompism

When Mudkipism evolves, it becomes Marshstompism, and proceeds to venture into less aquatic grounds in order to acquire further out territory. In naturalistic fashion, it leaves the mangroves it grew up in and, in this case, settles on the nearby beaches where it has a physical advantage when facing other Pokémon who struggle to move in muddy surfaces.

Personality
Marshstopism loves to roll around in and play in the muddy shores when the ocean's tide rolls down. When he is sleepy, he will borrow into the ground to repose.
