Pokémon Pokopia Bubbly Basin DLC: All 50 Pokémon and Where They Come From

Bubbly Basin adds 50 Pokémon, and 48 of them arrive by building the right habitat. The Pokémon Pokopia Expansion Pass — Part 1: Bubbly Basin arrived on 5 August 2026, opening an underwater town reached with the new Dive move. Below is every one of the 50, the habitat that brings it, and the short list of builds that covers the lot.

This is a Nintendo Switch 2 game and the DLC is Switch 2 only. The base game is required, the Expansion Pass is $34.99 and covers all three parts, and Part 1 itself is a 3 MB download — the content ships inside the free Ver. 2.0.0 update, and the purchase is the key that unlocks it. Checked on 6 August 2026, rechecked on 7 August.

How do you unlock Bubbly Basin in Pokémon Pokopia?

Finish the request “Raise the environment level!” in Bleak Beach, then learn Dive, which arrives with the free Ver. 2.0.0 update.

Both halves matter. The update is free and everyone gets it, but Dive alone does not open the Basin — the request is the gate. And the Expansion Pass has to be on your account before any of the 50 will register, which is what the Basin Pokédex means when it refuses to fill in.

What are all 50 Bubbly Basin Pokémon and where do they come from?

Here is the full Basin Pokédex in game order, with the habitat or habitats that attract each one. Where a Pokémon has more than one, any of them works.

Two entries in that table are not habitats at all, and they are the two the planner cannot help with. More on those below.

Which Bubbly Basin habitats are worth building first?

The cheap ones, by a wide margin — Coral Congregation costs three pieces of material and brings four Pokémon, while Mermaid’s Gym costs thirteen and brings one.

The pattern behind the chart is that the productive habitats are the plain ones. Basin Tall Grass is four pieces of seabed tall grass and nothing else, and it brings Totodile, Feraligatr, Mudkip and Buizel. The elaborate set pieces — the gym, the concert stage, the teatime table — are one-Pokémon builds, because they exist to attract one specific resident.

How many habitats do you need to register all 50?

Thirty of the 36 will register all 48 that a habitat can produce, and the first nine of those get you 27. Reading the table below: build best-first, and the last column is how many new Pokémon the next habitat after that point brings.

The elbow in that curve is the useful part. Building best-first, the ninth habitat is the last one that brings more than one new Pokémon; from the tenth onwards you are paying a whole habitat for a single entry. If you want the dex filled quickly, the order that gets you there is Coral Congregation, Basin Tall Grass, Swaying Flower Bed, Sandy Digging Spot, Swaying Flower Bed & Coral, Muddy Playtime, Ocean Treasures, Marine Mossy Rest Spot and Chimney Rocks Dig Site.

Our Bubbly Basin habitat planner does this for whichever ones you are still missing, rather than for the whole dex, and totals the materials.

If you are working through the Switch 2 release schedule, our Splatoon Raiders beginner’s guide covers the other big Nintendo launch of this stretch, and every weapon location in Beast of Reincarnation is the same kind of completion list as this one.

Which Bubbly Basin Pokémon are not habitat spawns?

Phione and Manaphy. No habitat produces either, which is why a build list that covers “everything” still stops at 48.

Phione comes from the Starmie Doll. Manaphy comes from progressing the Bubbly Basin story. Both are registered in the same Basin Pokédex as the other 48, so a checklist that shows 48 of 50 with every habitat built is not a bug — it is the last two waiting on something that is not construction.

Do any Bubbly Basin Pokémon only appear at certain times?

Four of the 50, and weather never matters for any of them.

Everything else in the Basin is listed as all day and all weather, so the only reason to wait is these four. Staryu is the one that catches people out, because Swaying Flower Bed also attracts three Pokémon that will turn up in daylight — the habitat looks like it is working while the one you wanted is not due for hours.

What do the 50 new Pokémon add to your workforce?

Water and Chop, mostly — nine Pokémon each — with the DLC’s rarest additions being the two that can Grow and the two that can Burn.

Most of the 50 have two specialties, which is why the numbers add up to more than 50. For a town that has just gained an underwater district, the Water bias is the point — but the Burn shortage is worth knowing before you plan around it, because Frillish and Jellicent are the only two that bring it, and both come from the same corner of the Basin.

What else does the free Ver. 2.0.0 update add?

Dive, underwater building, and railways that run from land into the water.

The update landed the same day as the DLC and is free to everyone who owns the base game. Alongside the Dive move it allows building structures and crop fields underwater, and laying railway track from the land down into the sea. None of that requires the Expansion Pass; only Bubbly Basin itself and its 50 Pokémon do.

What is in Part 2 and Part 3 of the Expansion Pass?

Part 2 arrives in late 2026 with more Pokémon, furniture and accessories but no new town. Part 3 follows in 2027, and that one does add a town.

One purchase covers all three, which is the main argument for buying the pass rather than waiting — there is no per-part price to compare. Nintendo has not given a Pokémon count for either future part, in keeping with not having given one for this part.

The bottom line

Build Coral Congregation, Basin Tall Grass and Swaying Flower Bed first: eleven pieces of material between them, twelve of the 50 Pokémon. Work down the cheap habitats before you touch the set pieces, because the expensive builds are all one-Pokémon builds. And when your Basin Pokédex sticks at 48 of 50 with every habitat standing, nothing has gone wrong — Phione and Manaphy were never going to come from a habitat.
