Isle Delfino is where Mario, Princess Peach, Toadsworth, and Toad have traveled to unwind and take it easy. On the other hand, once they arrived, they found out that the island had been polluted, which had caused its primary source of energy, the Shine Sprites, to vanish. The perpetrator physically resembles Mario, who is therefore held responsible for the mess. As a result, the portly plumber is obligated to clean up the island. Mario is provided with a device known as FLUDD, a backpack equipped with several water nozzles to assist him in cleaning up the graffiti and mud and locating the true villain. The gameplay consists of a mix of action and solving puzzles. It has a large number of stages, each of which has multiple episodes, as well as a large number of hidden secrets and unexpected occurrences.
