This is a gaming guide from Destructoid explaining how players can obtain the Starmie Doll, a valuable collectible item in the mobile/life-sim game Pokopia, within the Bubbly Basin area. Dolls are important because they unlock access to special "Dream Islands" containing exclusive resources and Pokémon, but the Starmie Doll is notably difficult to find since it is hidden as an obscured treasure item invisible until collected, unlike most other Dolls in the game.

To acquire it, players must raise Bubbly Basin's environment level to three, then progress the storyline through Popplio before being directed to help Frillish, who leads players on a treasure hunt to an underwater cave in the area's north-west corner; the Doll is ultimately found by smashing rocks with the Rock Smash move. Once obtained, the Doll summons Drifloon to transport players to the Starmie Doll Dream Island, which offers exclusive materials such as sea grapes, small coral and grubby pearls, as well as the chance to recruit the Pokémon Phione.
