What is the name of Part One’s new area in the Pokémon Pokopia Expansion Pass?

Bubbly Basin is the new area introduced in Part One of the Pokémon Pokopia Expansion Pass.

Bubbly Basin is an aquatic area explored underwater. Players reach it using Dive, a move added through a free update, and must also complete the required Bleak Beach request and know Surf before entering through the underwater gate.

The area adds more than scenery. It includes additional Pokémon, furniture items, a new outfit for Ditto, and new construction opportunities. The Expansion Pass is divided into three parts, with one purchase granting access to the content as it is released.

Bubbly Basin should not be confused with Bleak Beach or Rocky Ridges, which are base-game areas opened during the main adventure. Sparkling Skylands is another later location, but it is not Part One’s aquatic Expansion Pass area.
