Hippopotas is a quadruped, hippo-like Pokémon that is most commonly found in deserts and other arid places. Its skin color depends on gender: if male, it is tan with dark brown patches, and if female, its coloring is reversed. It has a large snout with round nostrils and eyes that protrude from the top of its head. It torso has mottled coloring and a small hole on its back. Each of its feet has two blunt claws, and it has a small tail. Hippopotas spends its time bathing in sand and avoids water at all costs. It covers itself in sand as a protective measure against germs and expels sand instead of sweat. When it walks through the sand, it shuts its nostrils. It prefers to travel in groups of ten.
