#258 Mudkip - The fin on Mudkip’s head acts as highly sensitive radar. Using this fin to sense movements of water and air, this Pokémon can determine what is taking place around it On land, it can powerfully lift large boulders by planting its four feet and heaving. In water, Mudkip breathes using the gills on its cheeks, and its large tail fin propels it through water with powerful acceleration. It sleeps by burying itself in soil at the water’s edge.
