What is the best way to get the Dive move and start building underwater in Pokémon Pokopia?
Forget basic sea-floor builds. Master Bubbly Basin with vertical floating hubs and the new 128-power generator limit. Build your undersea utopia today!
Key Takeaways
What: Bubbly Basin DLC introduces vertical underwater building and doubled power limits.
Why: To create efficient, multi-level floating hubs instead of standard sea-floor bases.
How: Use buoyant blocks for depth fine-tuning and 128 generators to power automated bubble machines and sensors.
The biggest mistake you can make in Bubbly Basin is looking down. While every other biome in Pokémon Pokopia forces you to build from the ground up, the Basin is designed to be suspended in mid-water. Most players treat the sea floor like a standard land plot, but the real advantage comes from ignoring the sand entirely.
Verticality and the Buoyancy Meta
Standard building logic suggests that a solid foundation is the first step. In this DLC, that logic is backward. By using buoyant blocks, you can create structures that float at specific, varied depths throughout the water column. This isn’t just a visual choice; it’s a functional one.
You can now fine-tune the depth placement of windows and doors, allowing you to stack rooms vertically without them touching the sea floor. Certain roof items have also been updated to block water, meaning you can create dry, breathable pockets inside these floating hubs. If you are only building on the bottom, you are missing out on the 3D space that makes this expansion different from a basic land reskin.
Powering the Deep: The 128-Generator Grid
Running a town underwater requires significantly more infrastructure than a sunlit village. To handle this, the Version 2.0.0 update quietly doubled the placement limit for power generators from 64 to 128. This extra capacity is vital because you’ll need it to run bubble machines and streetlights across multiple elevations.
For maximum efficiency, assign Pokémon with the Generate specialty to your town. They can power your grid while you focus on automation. You can also wire Tidal and Clear Bells to laser sensors and switches. This allows you to set up automated alerts that trigger when certain conditions are met, essentially turning your submerged base into a living, responsive machine.
The Sharpedo Submarine and Mobile Bases
If you want to move beyond a stationary town, you can blueprint a Sharpedo submarine. This isn’t just a vehicle for faster transit; it functions as a mobile Secret Base. You can design the interior rooms to serve as a portable headquarters, allowing you to take your crafting and storage with you as you explore the deeper trenches or head toward the mysterious hole in the sea floor.
Accessing the Basin: The Manaphy Sequence
Getting into the Basin requires a specific three-step checklist: the Expansion Pass, the Dive move, and reaching Environment Level 5 in Bleak Beach.
To get the move, talk to Professor Tangrowth outside the Bleak Beach Pokémon Center. He will point you toward an island to the north where you’ll find Manaphy. Feed Manaphy five bunches of seaweed to replenish its strength, and it will teach you Dive. Once you have the move, return to the Pokémon Center to find Popplio. Popplio will guide you to the underwater gate located behind a rocky overhang to the west.
Economic Shortcuts and Item Management
Managing resources in a submerged environment can be tedious without the right tools. The update adds a bulk move function, letting you shift items between your storage box and bag in one go.
For travel, prioritize the portal pod recipe. These pods cost 3,000 Life Coins and can be bought from the PC once you’ve leveled up Palette Town. Placing two of them creates a teleportation link, which is far more efficient than swimming back and forth to your house. Additionally, if you picked up the expansion pass before August 31, 2027, check your email for a serial code that grants 30 rare Pokémetal ingots to jumpstart your construction.
Comfort and Control Settings
Moving in a 3D underwater space can be disorienting. The developers added motion-sickness reduction settings for the camera specifically to help with the new vertical movement. You should also enable the setting that allows your character to keep moving while the move wheel is open. It makes navigating tight underwater corridors much smoother.
If you accidentally destroy a habitat while remodeling, don’t worry—Pokémon will now automatically move back in if you rebuild the same habitat in the same general area. This removes the frustration of having to re-assign residents after every minor architectural tweak.
