Pokémon Pokopia’s Expansion Pass Adds Bubbly Basin in August

Nintendo Direct announcements often set the tone for what players can expect next, and Pokémon Pokopia’s latest reveal is a clear example. The game’s Expansion Pass is set to begin in August with the underwater Bubbly Basin town—and that same month, every player will receive a free update that unlocks the Dive ability.

Bubbly Basin lands this August as the Expansion Pass opener

Pokémon Pokopia launched earlier this year on March 5, exclusively on Nintendo Switch 2, and today’s Nintendo Direct confirmed the start date for its Expansion Pass content. The first major addition is Bubbly Basin, arriving sometime in August as a new town built around an entirely underwater biome.

As the name suggests, Bubbly Basin is designed for underwater exploration. To access and develop the biome, players will need the new Dive ability. That ability is not given automatically; it must be earned by raising the environmental level in another location, Bleak Beach. Once that requirement is met, Dive becomes the key to building and experiencing what Bubbly Basin has to offer for underwater pocket monsters.

A free underwater update for everyone, not just Expansion Pass owners

Alongside the arrival of Bubbly Basin, Nintendo also confirmed that August will include a separate, free software update for all players. This update grants the Dive ability universally, meaning the underwater town’s core mechanic is supported even if someone does not yet engage with the Expansion Pass.

In other words, August is shaping up to be a two-part moment for Pokémon Pokopia: Expansion Pass owners get the new underwater town, while the broader player base receives the capability that makes that underwater gameplay possible.

What’s next after August: more features in late 2026, a new town in 2027

Bubbly Basin is described as the starting point for the Expansion Pass, but it is not the end of the roadmap. The Expansion Pass will expand further with additional features arriving in late 2026. Then, in 2027, a brand-new town will be added.

This staggered release plan suggests Pokémon Pokopia is moving toward longer-term content cadence rather than a single large drop. For players who enjoy progression and exploration, that also means the game’s world is expected to keep growing well beyond the initial August update.

Key points

• Bubbly Basin, an underwater town, is scheduled to be added in August.
• Dive is required to build and explore the underwater biome.
• Dive will be granted to all players via a free update in August.
• The Expansion Pass continues with more features in late 2026 and a new town in 2027.

Expert View

Pokémon Pokopia’s August rollout signals a strategy focused on sustaining engagement: it pairs a headline new location with a gameplay enabler delivered to the entire community. That approach can help reduce friction around new content—players who may not buy the Expansion Pass still get the core mechanic needed to participate in the underwater theme. For the broader market, it’s also a reminder that handheld-exclusive-style launches on newer platforms can quickly transition into multi-year post-launch plans, keeping the franchise’s community active between major town additions.
