All hands on deck for an island-hopping adventure starring Mario and Luigi. The brothers return for a brand-new adventure on the high seas! Set sail with Mario and Luigi on Shipshape Island (part ship, part island) and journey through the vast world of Concordia. Launch out of Shipshape’s cannon to visit, explore, and quest your way through islands that range from tropical rainforests to bustling cities. Meet new friends along the way, like Connie and Snoutlet (definitely not a pig), and encounter familiar faces from the Mushroom Kingdom like Peach and Bowser, who may help—or hinder—you on your journey!
