Azurill love to play in water, but can’t swim yet. If swept up in a current, Azurill can only wait to wash ashore somewhere else.

Marill’s buoyant ball lets it swim without drowning, but can be a vulnerability if left alone. Tyrogues that see the ball are known to snatch it and use Marill as exercise equipment.

Azumarill’s constant diving sometimes leads to a power that dwarfs other Pokémon in the area. It is said that nature photographers would rather swim through a river filled with Feraligatrs than Azumarill.
