What is the name of Pokémon Pokopia’s first expansion-pack area?

Bubbly Basin is the first expansion-pack area for Pokémon Pokopia. It launched in August 2026 as the opening part of a planned three-part paid expansion pass.

The expansion pass adds content beyond the original game, and Bubbly Basin is its first named installment. The remaining two parts are scheduled for late 2026 and 2027, so Bubbly Basin is specifically the first released section rather than the name of the entire pass.

Pokémon Pokopia’s downloadable content follows the game’s existing emphasis on exploration, habitats, and customization. Later updates also added diving, allowing players to reach underwater areas and encounter aquatic-themed Pokémon and furniture. Those update features are related to the game’s expanding world but should not be confused with the name Bubbly Basin itself.

The title is easy to mix up with a general description of water-based content. Bubbly Basin is a proper place name and the specific name of the first expansion area.
