During the last Nintendo Direct this June, we learned that Pokémon Pokopia would be getting a DLC in August, as well as a free 2.0 update introducing diving.

According to a Japanese ad released a few hours ago, the first expansion will be called Bubbly Basin and will be available starting August 5. Nintendo has yet to confirm this, though there’s really no doubt about it at this point.

This DLC is the first in a series of three, included in the game’s Season Pass, which is available for purchase already. It adds a new underwater city to the experience, offering plenty of new things to explore and new Pokémon to add to your Pokédex.
