What is the name of Pokémon Pokopia’s first paid expansion?

Bubbly Basin is the first paid expansion for Pokémon Pokopia.

It is part of a planned three-part Expansion Pass. Bubbly Basin released in August 2026, adding the first major paid-content chapter after the base game’s March launch.

The expansion is associated with the game’s later aquatic content. A related update allowed players to dive underwater and reach previously unexplorable parts of the map, with new water-themed Pokémon and furniture. That means Bubbly Basin is not simply a cosmetic pack or a renamed seasonal event.

Players may confuse the expansion with free updates or limited-time in-game events. The Expansion Pass is paid content, while Pokopia also features other additions and events that do not share the same naming structure. The remaining two Expansion Pass parts were scheduled for late 2026 and 2027, making Bubbly Basin the first installment rather than the complete DLC plan.
