I slipped beneath the surface and the world went quiet. For a heartbeat I thought Manaphy had slipped past me. You don’t come to Bubbly Basin unprepared.
I’ve spent hours cataloguing spawns, watching habitats shift, and comparing notes with Serebii and Moyens I/O screenshots so you don’t waste time chasing ghosts. I’ll point out which habitats actually matter, which Pokémon appear as gender variants, and which specials you want to farm first. Stick with me and you’ll build the right habitats in the right order.
All Bubbly Basin Pokémon in Pokopia
On my first swim I spotted a Cloyster tucked behind a swaying flower bed.
The basin is a treasure chest: coral, seaweed, and a few surprise spawns hiding in plain sight. Below you’ll find the official roster the game tracks for Bubbly Basin, plus the habitats each species prefers and the Specialities they offer. Use this as a practical checklist—build the habitats the table names, then rotate through them until the friends you need show up.

There are 50 Pokémon listed for Bubbly Basin in the game’s Pokédex (the count treats male/female variants as a single entry, so your own tally may read 52 if you separate them). Below is the full table — habitats, Specialities, and the exact order the official index uses — so you can prioritize habitat builds and requests on your Nintendo Switch while cross-referencing Serebii for spawn-rate notes.
How many Pokémon are there in Pokopia Bubbly Basin?

When I opened the Pokédex it showed 50 entries for this single underwater region. The game treats gender forms as the same entry number, so if you count male and female variants separately your personal list will read 52. Expect that number to creep up: additional Bubbly Basin Pokémon are slated for the Part 3 update of this DLC and may appear earlier in Part 2.
How many Pokémon are in Pokopia Bubbly Basin?
Answer: 50 official Pokédex entries (52 when counting gender variants separately). If you track spawn locations with Serebii while monitoring in-game requests on your Nintendo Switch, you’ll spot which habitats need fast upgrades.
Which habitats do I need to build for Manaphy and Phione?
Neither has a permanent basin habitat. Phione can appear on Starmie Doll Dream Island, while Manaphy becomes available only after you complete Popplio’s beautiful building request. Treat those as special targets: finish the associated building steps first, then funnel resources into the habitats the table names.
Where should I focus first to fill my Pokédex quickly?
Prioritize multipurpose habitats: Basin tall grass, Swaying flower bed, and the various coral spots spawn a large chunk of the roster. Your Pokédex becomes a living atlas if you map those three hotspots and rotate through requests and shop purchases.
Small practical notes: use Serebii for spawn confirmation, check Moyens I/O screenshots for visual cues, and keep an eye on community threads for Part 2/3 changes that may shift spawn behavior. Ready to chase the rares or would you rather argue whether Manaphy belongs in your party first?
