What was the first named part of Pokémon Pokopia’s three-part expansion pass?

Bubbly Basin was the first named part of Pokémon Pokopia’s three-part expansion pass.

The expansion pass adds post-launch content to the base game. Bubbly Basin released in August 2026, while the other two parts were scheduled for late 2026 and 2027 respectively.

The expansion content builds on Pokopia’s core idea of exploring and cultivating environments with Pokémon. Official material described later content as introducing aquatic-themed exploration, including diving, new Pokémon, and new furniture.

Bubbly Basin is the name of an expansion component, not the game’s main setting. The base story takes place in a post-apocalyptic version of Kanto, so players may incorrectly assume every named location is part of the original campaign rather than downloadable content.
