The Isle Delfino is a island-region in which the Mario game Super Mario Sunshine takes place. Isle Delfino is known for consisting of several attractions, including a four-star hotel and an amusement park. The stage Delfino Plaza from Super Smash Bros. Brawl is also set there, which serves as the main hub for Super Mario Sunshine. The themes of Delfino Plaza and Ricco Harbor are songs from this game, and are used in Brawl on the Delfino Plaza stage. Isle Delfino is a vacation destination for many members of the Mushroom Kingdom. The two species of natives are the Pianta and the Noki. Piantas are multi-colored and have what appears to be a palm tree sprouting from the top of their head. The Noki are small, shellfish creatures, but have humanoid aspects. Isle Delfino has a Shine Gate, which is where the Shine Sprites gather together, and produce the light to all of Isle Delfino. Isle Delfino itself is in the shape of a dolphin, hence the name.
In the game, Mario, Peach and Toadsworth travel to the island for a vacation. when they land at the Delfino Airstrip, a messy sight greets them. A humongous splat of a strange paint-like substance drawn in the shape of Mario's head. When they land Peach briefly see a clear blue version of Mario and a second after Peach looks away and then looks back, he is gone. Mario can jump off the ledge and swim to the other side and then get F.L.U.D.D.. F.L.U.D.D. will then introduce himself and his controls. Then you can start cleaning up the goop. A blob of the substance is located in the middle and when sprayed with water, a Piranha Plant-like creature will emerge from the goop. After Mario has defeated it, he will retrieve his first Shine Sprite in the middle of the Airstrip. After there will be a little cutscene where the Piantas wrongfully, forcefully and mistakenly charge Mario with the crime of the goop. Then Mario is assigned to clean up the entire island and return all the Shine Sprites to the Shine Gate. He is forbidden to leave until he does so.
There are various locations around the island where the goop is placed. Sometimes, civilians and Toads are trapped under there. When a particular number of Shine Sprites are collected, Mario will find that some areas in the plaza are covered in goop. When the mess is cleaned up, the landmark underneath will reappear with multi-colored 'M' drawn on it. These work in the same way as paintings in Super Mario 64 being able to teleport you to other places including Bianco Hills, Ricco Harbor, Gelato Beach, Pinna Park, Sirena Beach, Noki Bay, Pianta Village and Corona Mountain. Some bosses include Petey Piranha, Gooper Blooper, a massive Wiggler, Mecha-Bowser, King Boo, Eely-Mouth, and Shadow Mario who is later revealed to be Bowser's son, Bowser Jr.
