Poliun swims by using its two ears to propel itself through the water, cheering on any other swimmers it sees. These same large ears make it clumsy on land, as it can easily topple over.

At a meeting of Pokémon academics, it was announced that simultaneous exposure to electricity from a Plusle and Poliun will promote circulation and boost vitality. It is possible to see this Pokémon's spiral innards right through its thin skin.
