What was the first released expansion-pass part for Pokémon Pokopia called?

Bubbly Basin was the first released expansion-pass part for Pokémon Pokopia.

Pokopia has a paid three-part expansion pass. Bubbly Basin became the first part to release, arriving in August 2026. The remaining two parts were scheduled for late 2026 and 2027, respectively.

The expansion pass is separate from the base game released on March 5, 2026. That distinction helps avoid mixing up the original launch date with the later downloadable-content schedule.

Pokopia's post-launch content expands the game's world beyond its initial habitats. The game's basic premise remains the same: players shape environments, build spaces, and interact with Pokémon. Because the pass is divided into multiple parts, “Bubbly Basin” identifies the first installment rather than the name of the complete DLC package.
