What was the title of the first Pokémon Pokopia expansion area released in 2026?

Bubbly Basin was the first Pokémon Pokopia expansion area released in 2026.

Bubbly Basin is the opening part of Pokopia's paid three-part expansion pass. It arrived in August 2026, adding new content to the life-simulation game after the main release earlier that year. The expansion pass is designed to extend the world with additional areas, Pokémon, and features.

The title is especially associated with water-themed content. Official expansion information describes later exploration involving diving, aquatic Pokémon, and underwater furniture, while the broader pass is divided into three planned waves. Bubbly Basin is the name of the first released part, not the name of the entire pass.

Players may confuse it with later expansion content because the remaining two parts are scheduled for late 2026 and 2027. Those future waves have separate release timing, whereas Bubbly Basin specifically identifies the first 2026 installment.
