The announcement, relayed through coverage by fan site Serebii.net, outlines a two-part rollout that combines a free game update with paid Expansion Pass content.
According to the official information summarized by Serebii, the free update arriving August 5 will enable underwater exploration for players, expanding how environments are traversed in Pokémon Pokopia.
Separately, the paid Expansion Pass content launching the same day will introduce a complete new town for players to explore, adding additional locations and activities beyond the base game.
In journalistic terms, The Pokémon Company stated that the August release will include a complimentary update that unlocks underwater diving mechanics, while the paid Expansion Pass will provide a full new town and associated content.
The company also confirmed a second part of the Expansion Pass scheduled later in 2026 that will let players dress up their Pokémon companions with new appearance options.
Serebii published accompanying artwork tied to Expansion Pass Pack 2 showing character and Pokémon imagery, which the outlet posted alongside its coverage on July 29, 2026.
The site’s social posts noted artwork featuring multiple Pokémon associated with the expansion materials.
Beyond the DLC timing, The Pokémon Company also announced an in-game event titled Fetching Scales for Feebas.
That event is scheduled to run from August 13 through August 28, 2026, and will enable players to befriend Feebas and Milotic during the event window.
Players who own Pokémon Pokopia should watch the Nintendo eShop and official Pokémon channels for the update and Expansion Pass availability, and check Serebii.net for early coverage and artwork releases.
The Pokémon Company’s announcement gives clear dates for both the Bubbly Basin launch and the subsequent Feebas event, allowing fans and retailers to prepare for the mid-August activity in Pokémon Pokopia on Nintendo platforms.
