The number of coins in the sand will increase after Episode 4. The sand will also reveal several yellow coins, blue coins, and fruit if the player sprays along it. The beach runs along the eastern coast of the island, has several palm trees, a Pianta-shaped tree with a papaya known as the Deku Tree, and is home to the Great Sunflower and the Sunflower Kids. Pinna Island is split between two locations: a beach and a theme park. The Roller Coaster, the Ferris Wheel, and the Pirate Ships as seen in the Super Mario Sunshine intro Outside of Super Mario Sunshine, Pinna Park makes a cameo in the background of the Delfino Plaza stage in Super Smash Bros. In addition, it is the only location that contains two Yoshi eggs, one in the park and one on the beach (although the one found in the park is only available during Episode 6). Pinna Park is also unique in that it is the only location in the game where Yoshi is available in all 8 episodes after being unlocked. Instead, part of the beach theme uses a rearrangement of the secret levels that take place in the sky, making this the only main area in the game to use a cover of a secret level's music. Pinna Park is one of the few locations that features music that is not a variation of Delfino Plaza's music. It is also one of two locations that does not contain any nozzle boxes, the other being Sirena Beach. It and Gelato Beach are the only locations on Isle Delfino that are never covered in goop. Looking toward Pinna Park from Pianta Village during one of the episodes that takes place at night, the player can see that it is lit up, revealing that the park remains open at night. Additionally, Pinna Park is the only location from which Sirena Beach can be seen in the daytime.

Pinna Park can be seen from every location except for Noki Bay and the Delfino Airstrip.

A single boat sits in the water at the level access point, but it cannot be used by the player. This level is unlocked after a total of ten Shine Sprites have been collected, after which Mario can access Pinna Park by using a cannon found in the northwest corner of Delfino Plaza.

It is located just off the coast of Isle Delfino's mainland, and forms the "tail fin" of the dolphin-shaped island, hence its name: "pinna" is the Italian term for "fin" (additionally, a yellow Toad near the cannon leading to the island claims the island is called "the pineapple": "pinna" being a pun on "piña", the Spanish word for pineapple). Pinna Park is a large amusement park island found in Super Mario Sunshine, the overall island being known as Pinna Island.
