What changes in gameplay within the new aquatic biome
By accessing the bottom of the sea, virtual builders will be able to build their aquatic metropolis with the help of partners like Popplio and Ditto, solving tasks proposed by local creatures. The underwater environment requires different strategies and brings completely new game systems:
- Planting watermelons gains prominence in submerged farms, requiring aquatic species, such as Mudkip, to encase the seeds in oxygen bubbles, while allies with the Grow gift help shorten harvesting times.
- Engineering gains new proportions with floating blocks, tools that enable the assembly of suspended structures at different depth levels, guaranteeing a unique three-dimensional look.
- The lighting infrastructure and bubble machines depend on energy generated by specific monsters, like Chinchou, who use the Generate ability to keep the city running.
The decoration catalog receives themed additions, even allowing the assembly of a Sharpedo-shaped submarine to function as a private hiding place. Outside the city limits, adventurers can investigate a shadowy cave lit only by bioluminescent corals or use a Starmie doll to gain access to Dream Island, a space focused on multiplayer interaction. The news package also includes new costumes, improvements to Surfing mechanics and the possibility of preparing refreshing vitamins.
Next steps in the paid upgrade schedule
The second stage of the Expansion Pass, which arrives in the final stretch of 2026, focuses on visual customization, delivering outfits that combine the protagonist’s style with that of his teammates. Although it brings a renewed range of furniture and captureable species, this intermediate phase will not expand the map with new cities.

The promotion covers purchases made until August 31, 2027, with redemption via Mystery Gift released until September 30 of the same year.

New exploration technique revolutionizes game engineering
The arrival of version 2.0.0 implements the long-awaited Diving function, guaranteeing total freedom of movement through the game’s oceans. The legendary Manaphy is responsible for teaching the movement, but he only joins the team after the player advances through the “Bubbling Basin” arc, completes the mission “Increase the level of the environment!” and already have jumping and surfing skills.
With this new capacity for locomotion, the construction of parks and farms on the ocean floor becomes a tangible reality. The system even allows the installation of railways that cross the surface and descend into the depths, facilitating the transport of resources by carts and highlighting how the Nintendo Switch 2’s advanced hardware allows scene transitions without loading screens, something essential for sustainable urbanism at the bottom of the sea.
Seasonal quest focuses on capturing rare creatures
The game’s calendar will host the “Collecting Scales for Feebas” festival, scheduled to take place between 5am on August 13th and 4:59am on August 28th, in the UTC+9 time zone. The community’s goal will be to gather prismatic scales to exchange for marine decorations, which serve as the perfect bait to attract and recruit the coveted Feebas and Milotic to the metropolis.
Access to the temporary event requires that the software is updated to version 2.0.0 and that the player has already completed the reconstruction work at the local Pokémon Center. Furthermore, it is essential that the console’s internal clock is synchronized with the internet, as any divergence in date and time will prevent special missions from being activated.
