The Pokémon Pokopia Expansion Pass contains three parts.
Nintendo describes the paid pass as a three-part package adding more Pokémon, areas, characters, features, and decorative items. Part 1 is Bubbly Basin, while Part 2 is scheduled for late 2026 and Part 3 for 2027. One purchase provides access as the parts are released.
The structure matters because the pass is not a single expansion launched all at once. Its content is divided into staged releases, allowing the game’s world to grow over time. The first part also uses the Dive ability introduced in a free update, linking paid and free additions.
The number three can be confused with the number of major areas, towns, or new features shown in promotional material. The question asks about the pass itself: its planned content is divided into three parts.
