Pokémon Pokopia's upcoming Bubbly Basin DLC and a free update that introduces underwater exploration and building are potentially set for a release on August 5. This information surfaced following the appearance of a commercial announcing the expansion pass's first DLC, which was subsequently made private, suggesting it may have been released prematurely.

The Bubbly Basin DLC was initially revealed last month with an August release window. The accompanying free update will allow players to venture beneath the waves and construct creations in areas previously inaccessible due to drowning. Fans have noted the addition of new content, including "Asian temple-style kits," which are expected to appeal to builders who have already created themed environments with the base game's existing assets. The trailer also featured a live-action person wearing a Stunfisk hat, a Pokémon that has been the subject of previous leaks, offering some confirmation of its inclusion.

Confirmed Pokémon additions for the Bubbly Basin update include Mudkip, Crawdaunt, Staryu, Starmie, and Sharpedo, catering to enthusiasts of water-type Pokémon. While the official announcement has yet to be made, the private trailer indicates that further details and content may be revealed soon, making it an opportune time for players to consult existing guides for Pokémon Pokopia.
