Switch 2's Bubbly Basin DLC Brings Underwater Pokémon Home
Underwater Pokémon has always been a handheld-first experience. Ruby and Sapphire let GBA owners sink beneath Hoenn’s waves; Omega Ruby and Alpha Sapphire recreated that dive on 3DS. Then the mainline series went open-world, and the ocean floor quietly disappeared from the rotation. Bubbly Basin, the first paid expansion for the Switch 2’s cozy life sim Pokopia, finally pulls the franchise back under — on the kind of hardware where this series has always done its best work. The DLC hands you the power of Dive, drops you into a submerged town, and fills the place with the sea critters a landlocked Pokédex has been missing: Horsea, Luvdisc, Sharpedo, Corsola, plus the chronically underrated Chinchou and Lanturn.
Underwater Pokémon Was Always a Handheld Sport
The drought isn’t a coincidence — it’s a structural shift. Once Pokémon moved from random encounters to visible overworld spawns in Scarlet and Violet, true water-dwellers stopped fitting the format. You can’t wander the ocean floor if there’s no ocean floor to wander. Dive has been absent since the 3DS era, and with it went the franchise’s most atmospheric biomes. Bubbly Basin is Omega Force’s answer: a full biome built around a mechanic modern Pokémon forgot. The Dynasty Warriors studio is also exactly the right team for it — filling a reef with schooling Finneon and patrolling Sharpedo is, technically, just another crowd to render.
For Switch 2 players, that lineage matters. Pokopia is a Switch 2 exclusive — a game designed around short, on-the-go sessions — and its portable mode is where the cozy loop actually lives. Life sims are the perfect suspend-and-resume genre: ten-minute sessions to check habitats between errands, longer docked stretches when the schedule allows. Bubbly Basin doesn’t change that equation — it extends it, turning idle handheld time into aquarium time. Watching Horsea twirl in happy circles or cringing at Stunfisk’s flat-page insecurity beats any checklist chore. Even the DLC’s busywork, growing watermelons and assembling submarines, stays firmly in the “pick up, put down” lane.
Bioluminescence Was Made for Switch 2’s HDR Screen
This is a DLC that rewards the right screen. Chinchou and Lanturn are bioluminescent anglerfish — Lanturn’s entire identity is a glowing lure — and underwater light scattering is exactly the kind of visual data that pops on Switch 2 hardware. The hybrid’s 7.9-inch 1080p panel supports HDR and VRR in portable mode, which matters more here than in any dry-land biome Pokopia has shipped.
Neither Omega Force nor Nintendo has disclosed performance targets for Bubbly Basin in handheld mode, and water effects are notoriously expensive — flooded-town transparency, particle-heavy currents, and that fish school all stack up against a portable GPU. But the studio’s history rendering hundreds of simultaneous on-screen agents in Musou games is the right résumé for the job, and VRR smooths the frame-pacing dips that would scream on a fixed-refresh screen. If Polygon’s read is right — that Bubbly Basin previews how the upcoming Pokémon Winds and Waves handles sea life — the bar it sets here matters beyond one DLC. The Switch 2 inherits Pokémon’s underwater legacy, GBA to 3DS to hybrid, and it’ll be judged on how that plays in your hands. Play it in handheld mode, brightness up, and let Lanturn do the rest.
