An underwater laboratory sits near the bottom of Bubbly Basin's deep trench. It contains anchor-patterned furnishings and a wallpaper recipe. Bring Dive, Rock Smash and a reliable light before searching: the entrance is far below the bright streets, so a surface-level sweep will miss it.

Follow the vertical route down
- Locate the broad vertical gap beside the central cultivated terraces and fenced plots. Swim down between the large rectangular stone structures rather than following a street-level house entrance.
- Keep descending along the wall into the dark section. Look for the stone doorway beside the orange coral and inspect the opening; clear any breakable blocks that obstruct your approach.
- Enter the room with metal flooring, computer equipment and anchor-patterned furniture. Open the golden Poké Ball to learn the colorful-anchor wallpaper recipe.
Take furniture for the two patterns
The room contains both colorful and darker anchor designs. Keep patterned furniture or object-mode photos of it if you want to teach the designs to Smearguru. A patterned block is not a substitute for a furniture reference, and the wallpaper recipe does not unlock every solid block version.
Mark the return route before leaving
Place a light outside the doorway and another at a recognizable point higher in the shaft. Check their visibility while swimming upward so you can find the room again. Leave objects you cannot carry for a second trip instead of demolishing the landmarks that identify the entrance.
