Ocean Doors are one of the pieces you need to finish the ocean temple that Popplio asks you to build in Bubbly Basin. Unlike most of the parts for that structure, you can’t pick these up lying around the region. They exist only as a crafted item, and the recipe is buried in the rubble at the build site itself.
Quick answer: Clear the debris at the top of the stairs in the middle of Bubbly Basin, grab the Poké Ball hidden in that pile to unlock the Ocean Doors recipe, then craft two Ocean Doors using one Star-Spotted Rock each.
Where the Ocean Doors recipe is hidden in Bubbly Basin
The recipe sits inside a Poké Ball concealed by sand and debris at the top of the stairs in the center of Bubbly Basin. This is the same spot Popplio wants cleared to make room for the big building, which is above the cave entrance that leads to the Bubbly Basin Pokémon Center.

Note: If you’re bulldozing the site quickly, there’s a good chance you’ll scoop up the recipe without noticing. It counts toward finishing Popplio’s cleanup either way, so you don’t have to stop and hunt for it separately.

Once the recipe is unlocked, Ocean Doors are cheap to make. Each door costs a single Star-Spotted Rock, and the temple build needs two of them, so gather two Star-Spotted Rocks before you head to a workbench.
| Detail | Requirement |
|---|---|
| Recipe source | Poké Ball in the rubble at the top of the central stairs |
| Material per door | 1 Star-Spotted Rock |
| Doors needed for the temple | 2 |
| Total Star-Spotted Rocks | 2 |
Star-Spotted Rocks are extremely common throughout Bubbly Basin, and you can also collect them on the Dream Island you reach with the Starmie Doll. If you already cleared Popplio’s construction plot, you likely broke enough of these rocks to cover both doors without any extra farming.

How to confirm you have the recipe
You know the recipe is unlocked when Ocean Doors appears in your list at a crafting station. Because the Poké Ball is easy to pick up mid-cleanup, check your recipe list before assuming you missed it. Many players find it already sitting there after finishing the construction site.
If it isn’t listed, return to the plot at the top of the stairs and break any remaining blocks you skipped. The recipe is tied to that specific area, so continuing to clear it is the only thing you need to do.
Other ways to use the Ocean Doors recipe
The recipe stays available after the temple is done, so you can keep crafting Ocean Doors for your own projects. They work well when you’re setting up dedicated Pokémon homes across the Bubbly Basin Habitats, and they slot into any decorative build you want in the region as you bring the underwater area back to life.
