Ditto reaches Bubbly Basin in Pokémon Pokopia by learning Dive during the free Version 2.0.0 update, then following a short quest that begins in Bleak Beach. The underwater town itself is paid content: you need the full game and the Pokémon Pokopia Expansion Pass. Before the quest will appear, raise Bleak Beach to Environment Level 5 or higher, and make sure Ditto knows Jump and Surf. This guide separates the free ability from the paid destination and walks through the Manaphy and Popplio objectives in the order they occur.

Nintendo explains that environment levels rise through ordinary settlement work: befriend Pokémon, build habitats, improve comfort and complete requests. If the request is not available, keep developing Bleak Beach rather than searching for a hidden entrance. Nintendo’s preparation guidance has the full prerequisite explanation in its preparation guide.

Is Dive free, or do I have to buy the Expansion Pass?
Dive is free; Bubbly Basin is paid. Installing Version 2.0.0 gives every player the new underwater-exploration ability, but entering the Bubbly Basin town requires Pokémon Pokopia plus the Expansion Pass. Nintendo states plainly that both are needed to visit Bubbly Basin in its official access article.
That distinction matters if you own the base game but have not purchased the pass. You can still complete the Dive teaching sequence after the free update; the gate will not become an accessible DLC destination until the pass is installed. Conversely, buying the pass does not replace the update or the in-game prerequisites.
The Pokémon Company describes the pass as a package of three content drops. Bubbly Basin is the first; a June 2026 announcement scheduled Part 2 for late 2026 and Part 3 for 2027, although release timing can change. Nintendo’s US article lists regular prices of $69.99 for the game, $34.99 for the Expansion Pass and $104.99 for a game-and-pass bundle. Those are US prices from the cited publication and may differ by region or storefront.
How do I start the Dive quest in Bleak Beach?
Once Bleak Beach meets the level requirement and the game is updated, Professor Tangrowth starts the chain. The following sequence combines Nintendo’s access requirements with the detailed objective order reported by Video Games Chronicle’s walkthrough.

- Finish “Raise the environment level!” Continue improving Bleak Beach until its Environment Level reaches at least 5. The request is the gate for the new content, not a suggestion.
- Confirm Jump and Surf. You need both abilities to navigate the route Nintendo describes. If one is missing, complete the earlier progression that grants it before looking for Tangrowth.
- Speak to Professor Tangrowth in Bleak Beach. Tangrowth identifies a newly available island and directs Ditto toward it. The conversation is the practical start of the Dive quest.
- Travel to the island. Follow the newly indicated route and locate Manaphy. The island is where the materials for the next objective are collected.
- Collect five bunches of seaweed. VGC’s walkthrough specifies five bunches around the island. Pick up all five and bring them to Manaphy.
- Let Manaphy teach Dive. After receiving the seaweed, Manaphy teaches Ditto Dive. This is the free-update ability, so the teaching event is not itself a separate purchase.
- Complete Manaphy’s follow-up request. Manaphy sends Ditto to retrieve an item in a small cave. Enter the cave, collect the requested item and return to Manaphy to report back.
- Return to Bleak Beach. After the cave objective is complete, go back to the beach rather than trying to swim straight to the DLC area.
- Speak with Popplio. Popplio points out the underwater gate. Use Dive at that location to begin the route into Bubbly Basin.
The seaweed count and the small-cave retrieval are secondary-walkthrough details; Nintendo’s official pages establish the required environment level, abilities and Popplio’s role but do not publish every intermediate collection step. If your journal appears to pause after Tangrowth’s conversation, check the island carefully for all five seaweed bunches and then revisit Manaphy.
Where is the Bubbly Basin entrance?
The entrance is an underwater gate in the Bleak Beach area, and Popplio reveals its location only after Ditto finishes Manaphy’s requests. Do not expect the gate to function immediately after installing Version 2.0.0: the game uses the Tangrowth, Manaphy and Popplio sequence to unlock the route.
Recommended Free Tools
After Popplio’s conversation, return to the water around Bleak Beach and look for the indicated gate. Dive at the opening to transition into Bubbly Basin. If the gate is visible but does nothing, check the three most common causes: the cave item has not been delivered to Manaphy, Popplio has not been spoken to after that delivery, or the Expansion Pass is not installed on the same Nintendo Switch 2 user account that is running the game.
What should I do if the request or characters do not appear?
Progression is conditional, so work through the checks below in order.

- Check the software version. Bubbly Basin launched with Version 2.0.0 on August 5, 2026. Close the game and install the available update before attempting the quest.
- Recheck Environment Level. The threshold is 5 or higher in Bleak Beach. Raising another area’s level does not substitute for the beach requirement.
- Verify both abilities. Nintendo’s preparation instructions call for Jump and Surf. If the beach has reached the required level but Tangrowth is not advancing, confirm that Ditto has learned both.
- Finish every active Manaphy objective. The five seaweed bunches are followed by the small-cave item. Returning to Bleak Beach early will not trigger Popplio’s gate instruction.
- Install and verify the pass. The free update can teach Dive without the DLC, but the town requires the Expansion Pass. Check the console’s downloadable-content management and make sure the pass is attached to the account that owns the game.
- Speak to characters again. Talk to Tangrowth, Manaphy and Popplio after completing each objective. Some progression flags are set by the follow-up conversation rather than by collecting an item alone.
These checks distinguish a progression condition from a missing purchase. If Dive works but the town remains closed, the ability is functioning correctly; the remaining issue is usually the unfinished Popplio step or DLC entitlement.
What is actually included in Bubbly Basin?
Bubbly Basin is more than a single underwater corridor. Nintendo describes it as an underwater town with new Pokémon, restoration tasks and building-focused activities. The area adds furniture and outfits, introduces watermelons and smoothies, and includes buoyant blocks designed for floating underwater buildings.
Quick wins for a faster PC:
Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →The Expansion Pass content also includes a Starmie Doll Dream Island. That is separate from the basic route into town but gives builders another themed space to develop. The design emphasis is therefore on extending Pokopia’s settlement loop underwater rather than treating Dive as a one-time traversal animation.
Because Dive is part of the free update, owners of the base game can learn the ability even if they decide not to buy the pass. The paid entitlement determines whether the underwater town and its additional restoration and construction content can be entered.

Which version, platform and date apply?
Pokémon Pokopia launched on March 5, 2026, and the Bubbly Basin content arrived with Version 2.0.0 on August 5, 2026. Nintendo identifies Nintendo Switch 2 as the platform for the game and its Expansion Pass. This guide applies to that release and date; storefront availability, regional pricing and future pass schedules can change.
Nintendo’s access article says individual DLC parts cannot be bought separately. Purchasing the Expansion Pass grants the three planned content drops as they release, while the game-and-pass bundle combines the base game with the pass. Confirm the current price and regional listing in your own Nintendo eShop before buying, especially if you are comparing a bundle with an existing copy of the game.
What is the shortest checklist for reaching Bubbly Basin?
- Update Pokémon Pokopia to Version 2.0.0 or later.
- Raise Bleak Beach to Environment Level 5 or above by completing requests, improving comfort, building habitats and befriending Pokémon.
- Make sure Ditto knows Jump and Surf.
- Talk to Professor Tangrowth in Bleak Beach.
- Travel to the newly identified island.
- Give Manaphy five bunches of seaweed.
- Retrieve Manaphy’s requested item from the small cave and report back.
- Return to Bleak Beach and talk to Popplio.
- Use Dive at the underwater gate Popplio reveals.
- Install the Expansion Pass before trying to enter the Bubbly Basin town.
The key point is the order: the update supplies Dive, the Bleak Beach and Manaphy objectives teach it, Popplio reveals the gate, and the Expansion Pass authorizes the destination.
Frequently Asked Questions
Can I learn Dive if I do not own the Expansion Pass?
Yes. Dive is part of the free Version 2.0.0 update, so the teaching event with Manaphy does not require the pass. Without the pass, however, the Bubbly Basin town remains unavailable.

Is Bubbly Basin available on the original Nintendo Switch?
The official materials identify Nintendo Switch 2 as the platform for Pokémon Pokopia and this Expansion Pass content. They do not announce an original-Switch version, so check Nintendo’s current regional listing rather than assuming cross-generation support.
Does the Expansion Pass include later Pokopia areas?
It is described as a three-content-drop package. Bubbly Basin is Part 1; the June 2026 announcement planned Part 2 for late 2026 and Part 3 for 2027, subject to schedule changes.
What can I build underwater after entering Bubbly Basin?
Nintendo highlights buoyant blocks for floating underwater buildings, along with new furniture and outfits. The area also adds watermelons, smoothies, new Pokémon and a Starmie Doll Dream Island for additional themed building.
