What was the title of Pokémon Pokopia’s first paid expansion-pack installment?

Bubbly Basin was the first installment of Pokémon Pokopia’s paid expansion pass.

The expansion pass was planned as a three-part release. Bubbly Basin launched in August 2026, while the second and third parts were scheduled for late 2026 and 2027. This structure extends Pokopia’s world beyond its original release while preserving the game’s emphasis on exploration, construction, and Pokémon habitats.

The later content also expands the kinds of environments players can access. A subsequent update allows Ditto to dive underwater, reaching previously unexplorable areas and encountering aquatic-themed Pokémon and furniture. Those features are connected with the game’s continuing development after launch.

Bubbly Basin should not be confused with the name of the entire expansion pass. It is specifically the first part of the three-part paid package. The distinction matters because the pass includes multiple installments with separate release timing.
