What was Pokémon Pokopia’s first expansion, released in August 2026, called?

Pokémon Pokopia’s first expansion was called Bubbly Basin.

Bubbly Basin released in August 2026 as the first part of a paid three-part expansion pass. The additional content expanded Pokopia after its March 5, 2026, launch and formed part of the game’s continuing post-release plan.

The expansion pass was structured in three parts. Bubbly Basin was the first installment, while the other two parts were scheduled for late 2026 and 2027 respectively. This makes Bubbly Basin different from the game’s free update, which was separate from the paid expansion pass.

Pokopia’s expansion content also introduced aquatic-themed elements, including the ability to dive into water and reach previously unexplorable regions. Those additions brought new Pokémon and furniture connected with the water-focused material.
