It has a large head with a blue fin on top and a light-blue tail fin, black beady eyes, orange star-shaped gills on its cheeks, and can detect changes in air and water currents using its head fin. Mudkip is capable of moving or crushing boulders larger than itself and has a powerful acceleration provided by its large tail fin to propel it through the water.

In the wild, it sleeps by burying itself in soil at the waters edge.
