What this site does
The habitat list, the Pokédex and the material lists exist already, as separate tables. This site joins the three together, because that join is where the practical questions live.
- Every source habitat per Pokémon, not one primary habitat. 19 of the 50 Pokémon can come from more than one habitat, and every card here lists all of them, so you can pick whichever you were going to build anyway.
- Value ranking across all 36 habitats. Pokémon spawned divided by distinct material types, calculated here. The best row on the current data is Basin tall grass at 4.00.
- Material totals for a plan, not for one habitat. There are 74 distinct material types across the whole region; the planner only totals the ones your remaining Pokémon actually require.
- Progress that survives closing the tab. Collecting 50 Pokémon, 48 of them across 36 habitats, is not a one-sitting job, so the tools keep your ticks in this browser.
What is free, and what the $34.99 actually buys
This is the single thing most people get wrong on the way in, so it is worth being blunt about it. Two things shipped on 5 August 2026: a free update, Ver. 2.0.0, and a paid one, Expansion Pass Part 1. Dive — the move everyone associates with the underwater update — is in the free half. You can learn it, and you can swim with it at Bleak Beach, without spending anything. What the money buys is the place: Bubbly Basin, the region the 36 new habitats and 50 new Pokémon live in.
Free — Ver. 2.0.0
- Dive itself — underwater breathing, underwater habitats, and interacting with the ocean Pokémon
- Buoyant Blocks, which let a structure sit at any height in the water column instead of only on the seabed
- New hair colours and new emotes
- Bulk storage transfer and shared storage
Expansion Pass — $34.99
- The Bubbly Basin area itself
- 36 new habitats and 50 new Pokémon
- Dream Island, an extra dream island
- A new Ditto outfit
- New furniture and ocean-themed decorations
- An in-game watermelon
- The Sharpedo submarine, which makes a room a bit like a secret base
- An enhanced Surf move
The price covers all three Parts rather than just this one. Part 2 is due late 2026, which two independent outlets report, though nobody has published a date. What is in Part 2 is a thinner claim: according to Nintendo Life, and we have not found a second source, it is wearable accessories for your character and your Pokémon, more Pokémon, more furniture, and no new town. A third Part has been announced to exist, with neither contents nor date attached.
On the Pokémon themselves: the 50 lean heavily Water, and there are no Legendaries at all. The two Mythicals, Manaphy and Phione, are the two that no habitat produces — which is exactly why a tracker that counts habitats instead of Pokédex entries ends up reporting the wrong total.
The launch trailer, if you want to see the place first
Nintendo's own trailer is the honest way to answer “is this worth $34.99 to me” before reading anyone's opinion, ours included. It stays cold until you press play — no request leaves this page for YouTube beforehand, and the card is drawn here rather than copied from them.
The four tools, and the question each one answers
They share two lists — the Pokémon you have ticked and the habitats you have marked as built — so work you do in one shows up in the others. Both lists live in this browser and nowhere else.
What the numbers say once the tables are joined
Everything in this section is arithmetic over the habitat table, not a figure lifted from a guide. It is also the part no single source publishes, because it only exists once the habitat list and the Pokédex are put side by side.
Which habitats pay back most per material
Divide the distinct Pokémon a habitat spawns by the number of distinct material types it asks for and the spread is wider than it looks in a list. Basin tall grass and Swaying flower bed sit at the top with 4.00 — 4 Pokémon each for a single material type. Mermaid's Gym sits at the bottom with 0.13, asking for 8 distinct material types to produce 1. That is roughly a thirtyfold difference in what a build gives you back, and it is the reason the order you build in matters more than the total number of habitats you eventually put up.
The ratio is a rough guide and nothing more. Quantities are not in it: Basin tall grass asks for Seabed Tall Grass ×4 and still counts as one material type, which is a large part of why it sits at the top. It also knows nothing about where any of those materials are found, because our dataset does not carry that, so it cannot tell you which build will eat your afternoon.
How many Pokémon have exactly one source
29 of the 50 are spawned by exactly one habitat. 16 have two, 3 have three — Totodile, Barboach, Luvdisc — and 2 have none at all. The first number is the practical one: for 29 Pokémon there is no substitute build, so however badly that habitat scores on value, it is not optional. Value ranking tells you what to build first; the source count tells you what you cannot avoid building at all.
How many habitats a full collection really needs
Not 36. Running a greedy cover over all 48 habitat-bound Pokémon lands on 30 habitats; the remaining 6 spawn nothing that those 30 have not already produced. That is a coverage result rather than a cheapest-materials result, and it assumes you are starting from zero — the planner re-runs the same calculation against what you have actually ticked, so the number it shows you will be smaller.

Getting in, and what the game asks of you next
Learning Dive is a five-step errand with three prerequisites: the Jump ability, the Surf move, and the completed Bleak Beach request “Raise the environment level!”. With those done, you go to Bleak Beach, talk to Professor Tangrowth outside the Pokémon Center, walk the shoreline collecting five Seaweed, and hand all five to Manaphy on the island to the north. That delivery is the trigger. If you own the Expansion Pass, Bubbly Basin opens at that moment; if you do not, you still keep Dive. Four independent guides report the chain the same way.
What happens after that is on much thinner evidence. According to Nintendo Life, and we have found no second source for any of it, the sequence inside Bubbly Basin is: raise the Environment Level to 3 by discovering habitats and befriending Pokémon, build the Ocean Temple, rebuild the Pokémon Center once the rebuilding kit appears in its shop, then push the Environment Level to 5, with Manaphy encountered after the temple is finished. The same single source is where the temple's material quantities and the “needs 15 Pokémon” figure come from. We have left all of it labelled rather than dropping it, because it is the only account there is — but it is reported, not confirmed.
The practical reading is simple enough: whatever the later goals turn out to be, the first one is discovering habitats, and that is the thing this site is built to make faster.
Questions people are actually asking
Can I go underwater without buying the Expansion Pass?
Yes. Dive arrived with the free Ver. 2.0.0 update and works at Bleak Beach. The Expansion Pass buys the Bubbly Basin area itself, along with its 36 habitats and its 50 new Pokémon — 48 of them from those habitats, Manaphy and Phione from elsewhere.
How many new Pokémon does Bubbly Basin add?
50. Forty-eight of them come from the 36 new habitats; Manaphy arrives through the story and Phione through the Starmie Doll, so neither is tied to a habitat. They are mostly Water types, and there are no Legendaries.
How do I get Manaphy and Phione?
Neither is tied to a habitat. Manaphy comes through story progression; Phione comes with the Starmie Doll.
How much is the Expansion Pass?
It is $34.99, and that one purchase covers all three Parts. Part 2 is due late 2026 with no firm date announced.
What is in Part 2?
According to Nintendo Life, and we have not found a second source for any of it: wearable accessories for your character and your Pokémon, more Pokémon, more furniture, and no new town this time. Treat the whole list as unconfirmed, not just the part about the town. The late 2026 timing does have a second source.
Which habitat should I build first?
It depends on what you still need. If you are starting from nothing, Basin tall grass and Swaying flower bed pay back the most per material type: one material type each, four Pokémon each. Mermaid’s Gym is the worst ratio — eight distinct material types for one Pokémon — but it is the only habitat that spawns Starmie, so it is one to leave late only if Starmie is already ticked. A low ratio never means skippable when the habitat is a species’ only source.
How many of the 36 habitats do I actually have to build?
Thirty, if you are starting from nothing and want every Pokémon a habitat can give you. That is what a greedy cover over all 48 habitat-bound species comes out at on our data, and the other six habitats spawn nothing the first thirty have not already covered. It is a coverage figure, not a cheapest-materials figure, and it drops as you tick things off.
How many Pokémon come from only one habitat?
Twenty-nine of the 50. Sixteen have two source habitats, three have three, and Manaphy and Phione have none. The 29 single-source entries are the reason a habitat with a poor value ratio can still be compulsory.
What did the free Ver. 2.0.0 update add?
Dive itself, Buoyant Blocks that let you build at any height in the water column rather than only on the seabed, new hair colours and emotes, and bulk storage transfer with shared storage. None of that needs the Pass.
Does my progress sync between devices?
No. It lives in this browser only — no account, no login. Clearing site data clears your ticks.
Is this an official Nintendo site?
No. It is a fan-made reference with no affiliation to Nintendo, Game Freak or The Pokémon Company.
