It is an island located off the south coast of Renbow Island in the Obliviaregion. One of the three major areas of Dolce Island is Southern Beach (Japanese: みなみのはまべSouth Beach) which is where the player washes up on shore after crashing into the Western Sea. North of South Beach is Heights (Japanese: たかだいHighgrounds) where the player first meets Ukulele Pichu and Booker. Heights is home to Ukulele Pichu and its friends as well as being the part of Dolce Island where one of the five beacons that need to be activated later in the game is found. Eastern Beach (Japanese: ひがしのはまべEast Beach) is the area closest to Renbow Island. There is a pier on this beach that is used for docking the boat that transports the player to and from the island. Later in the game, players will not be able to access the island, as the Societea launched the cannon in the Sky Fortress that shot a huge destructive blast of energy which had vaporized the entire island with a blast of energy. The Pokémon originally located here can be found on other islands in the Oblivia region afterwards, since residents of Cocona Village on Renbow Island evacuated all of the Pokémon to save them from the explosion.
After the main storyline has been completed, Nema initiates a quest which leads to her creating a model of Dolce Island where the player can find the previous boss Pokémon that can be re-battled there.
