Let's take a bath!
New Event Distribution
Let's take a bath with a new Pokémon species that has recently been discovered in Emera Town! These Pokémon like to play in the water where they create huge piles of foam. They leave trails of foam wherever they go - the mayor of our town has already issued a decree that these Pokémon should not be taken to the Emera beach. The consequences would be fatal!
If you are a responsible trainer, however, then you can obtain an egg of this species in our new Event Distribution. Good luck!
