Bubbly Basin now has a date. Nintendo confirmed during last month’s Nintendo Direct that Pokémon Pokopia Expansion Pass Part 1 — Bubbly Basin — launches on 5 August 2026. A seven-minute trailer released this week fills in everything fans were waiting for: the full Pokémon roster, a brand-new field move, and an extended look at the underwater world beneath Pokopia’s surface.
We first covered Bubbly Basin in June when The Pokémon Company announced the Expansion Pass with only a broad “August” window. Now we have the date — and considerably more detail.
Fourteen Pokémon Join the Roster
The trailer confirms 14 returning Pokémon making their Pokopia debut in Bubbly Basin — an appropriately aquatic lineup anchored by mythical and Water-type fan favourites:
- Manaphy, Popplio, Mudkip, Chinchou, Lanturn
- Buizel, Corphish, Totodile, Dhelmise
- Golisopod, Corsola, Frillish, Lumineon, Sharpedo
Sharpedo earns a starring role beyond its spot on the roster: the Brutal Pokémon doubles as a rideable submarine, letting you pilot it through underwater passages into a dedicated deep-sea chamber.
Dive: Free for Everyone in Version 2.0
One of the bigger reveals is the new Dive field move, which lets your Pokémon plunge beneath the surface to explore Bubbly Basin’s underwater zones. Dive arrives as part of the free Version 2.0 update launching alongside the DLC — so all Pokopia players can access it, Expansion Pass or not.
Smoothies and the Sharpedo Sub Room
Bubbly Basin adds two new mechanics to the mix. Smoothies are a crafting and food system built around ingredients found throughout the aquatic biome. The Sharpedo Submarine Room is a deep-sea area exclusively accessible by riding Sharpedo through the underwater tunnel network — a new type of secret area for Pokopia.

Expansion Pass: Three Parts, One Price
Bubbly Basin is Part 1 of a three-part Expansion Pass. Release windows and content details for Parts 2 and 3 have not yet been announced. The full Expansion Pass is priced at USD $34.99, with regional pricing available in local storefronts. As Pokopia launched simultaneously worldwide, Bubbly Basin is expected to go live in Singapore on the same date: 5 August 2026.
