What was Pokémon Pokopia’s first paid expansion-pass town called?

Bubbly Basin was the first paid expansion-pass town for Pokémon Pokopia.

Bubbly Basin launched on August 5, 2026, as Part 1 of the Pokémon Pokopia Expansion Pass. It adds a new town to explore along with additional Pokémon and furniture, extending the base game’s focus on creating and enjoying Pokémon habitats.

The expansion also connects to a free update that adds the move Dive. With Dive, players can go beneath the waves and explore Bubbly Basin’s underwater town, giving the expansion a distinct aquatic setting.

Bubbly Basin is only the first of three planned expansion-pass parts. Part 2 is scheduled for winter 2026 and adds accessories, Pokémon, and furniture without introducing a new town. Part 3 is scheduled for 2027 and includes another new town.
