Ricco Harbor is the second main stage of Super Mario Sunshine. Located on Isle Delfino's southern coastline, this busy port consists of several structures built along the docks, as well as a complex series of support beams and catwalks hanging over several seafaring vessels moored in the harbor's waters. This stage becomes available once Mario has collected at least three Shine Sprites and defeats the Polluted Piranha that has engulfed Delfino Plaza's Boathouse; it can be then be reached though the "Rainbow M" portal on the side of the Boathouse. "Ricco" is the Italian word for "rich," likely referring to the profitable commerce conducted through the harbor.
Mario is dropped into the level in a small paved area with a number of warehouses. Near this area there are two boats and stretching out across the water there is a long and winding system of scaffolding. Along one side of the level there are a number of coastal shops, a helipad, and a lighthouse with scaffolding around it.
