The curled hair on Politoed’s head is proof of its status as a king. It is said that the longer and more curled the hair, the more respect this Pokémon earns from its peers. If Poliwag and Poliwhirl hear its echoing cry, they respond by gathering from far and wide. Whenever three or more of these get together, they sing in a loud voice that sounds like bellowing.
