The Pokémon Company has set August 5 as the release date for Bubbly Basin, the first paid DLC drop for Pokémon Pokopia, arriving alongside a free version 2.0.0 software update that adds a new Dive move to all players regardless of whether they purchase the expansion (Gematsu).

Bubbly Basin introduces an underwater exploration area accessible via that Dive move. The underwater zone resembles the ruins of Cerulean City, a location longtime Pokémon players will recognize from the original Game Boy-era titles. The DLC also adds buoyant floating blocks that enable three-dimensional underwater builds, as well as a new crop: watermelon (Engadget).

The structural decision worth noting is how The Pokémon Company has chosen to distribute this content. Bubbly Basin cannot be purchased on its own. It is available exclusively through the Pokémon Pokopia Expansion Pass, which costs $35 and includes all three planned major DLC drops. Part 2 is scheduled to arrive in late 2026, with Part 3 details still to be disclosed (Pokémon official expansion page). Expansion Pass purchasers also receive bonus recipes and 30 rare Pokémetal ingots as an immediate perk.

Meanwhile, the Dive mechanic itself is being distributed as a free update to the base game. Anyone playing Pokémon Pokopia, not just Expansion Pass buyers, will have access to the move when version 2.0.0 goes live on August 5. This is a familiar distribution pattern in the games industry: gate the new area behind paid content, but make the underlying mechanic that enables traversal freely available so the player base doesn't fragment. We have seen analogous approaches with vehicle or movement updates in live-service games where the base capability ships free and the content built on top of it is monetized.

Pokémon Pokopia launched on March 5, 2026 as a Nintendo Switch 2 exclusive (Pokémon official news). It is a life simulation game in which players take on the role of a Ditto, the shape-shifting Pokémon known for its transformative abilities (Pokémon official site). The game is available in both physical and digital formats, while the Expansion Pass itself is digital-only (Nintendo UK store; Nintendo US store).

A Nintendo Switch 2 + Pokémon Pokopia hardware bundle was released on July 23, 2026, roughly two weeks ahead of the Bubbly Basin announcement (Nintendo). The Pokémon Company formally announced Part 1 of the Expansion Pass on July 29, 2026 (Pokémon press release).

The cadence here is deliberate. A hardware bundle aimed at new adopters drops first, expanding the installed base. Then comes the first paid DLC wave, giving those new players, along with early adopters from the March launch, a reason to invest further. With three DLC drops planned under a single $35 pass and Part 2 already slotted for late 2026, The Pokémon Company is committing to a content roadmap that keeps Pokopia in the active rotation through at least the end of this year and likely into 2027.

The underwater build mechanics are the most technically interesting addition for anyone who follows game design. Buoyant floating blocks that function in a three-dimensional underwater space suggest a physics system that accounts for buoyancy, water resistance, and gravity simultaneously. Life simulation games with construction systems have historically struggled with underwater building because the physics interactions get complicated quickly. If Pokopia's implementation handles this gracefully, it would be a meaningful addition to the genre's toolkit, not just a content drop.

The free-to-all Dive move also matters for multiplayer and shared-world considerations. If Pokopia follows the pattern of other life simulation titles where players visit each other's builds, having Dive available universally means underwater constructions are at least theoretically accessible to any visitor, not just paying customers. That keeps the social graph intact while still giving pass holders the exclusive content to build with.

For a game that has been on the market under five months, the pace of the first major content delivery is brisk. The August 5 launch gives The Pokémon Company a summer-window content spike, with Part 2 following before year-end. Whether three DLC drops over roughly twelve months will satisfy the player base or strain the development pipeline is an open question that only the release cadence will answer.
