What is the first paid expansion area released for Pokémon Pokopia?

Bubbly Basin is the first paid expansion area released for Pokémon Pokopia.

Bubbly Basin is Part 1 of the three-part Pokémon Pokopia Expansion Pass. It adds a new town to explore, along with additional Pokémon and furniture. The expansion launched in August 2026, after the base game’s March 5 release.

The content is connected to a free software update that adds the move Dive. By using Dive, players can travel beneath the waves and explore Bubbly Basin’s underwater town, opening a new aquatic area beyond the original regions of the map.

The remaining Expansion Pass parts follow a different schedule. Part 2 is planned for late 2026 and focuses on accessories, more Pokémon, and furniture without adding a new town. Part 3 is planned for 2027 and will introduce another town. Bubbly Basin is therefore both the first expansion part and the first underwater destination.
