Which town was added in Part 1 of the Pokémon Pokopia Expansion Pass?

Bubbly Basin was added in Part 1 of the Pokémon Pokopia Expansion Pass.

The first expansion-pass part released on August 5, 2026 and introduced Bubbly Basin as a new town to explore. It also added additional Pokémon and furniture, expanding the creative and social possibilities of the main game.

Bubbly Basin is distinct from the Withered Wasteland, where the base game begins. The wasteland is the original story setting that Ditto works to restore, while Bubbly Basin is downloadable content released later as part of a three-part paid pass.

Part 2 was scheduled for winter 2026 and was described as adding accessories, more Pokémon, and new furniture without introducing a new town. Part 3 was planned for 2027 and was set to add another new town, so Bubbly Basin specifically belongs to Part 1.
