Isle Delfino

From Mariopedia

Isle Delfino is a sun drenched island in which Super Mario Sunshine takes place. It was protected by 120 Shine Sprites that gathered at the Shine Gate before Bowser Jr. as Shadow Mario wrecked havoc on the island causing them to flee.Mario gets framed for causing havoc among the island and he can't leave until he gets all of the shine sprites back. It also appears in Super Smash Bros. Brawl as a default stage.
