Set sail on an island-hopping adventure starring Mario and Luigi The brothers return for a brand-new adventure on the high seas! A mysterious power has fractured the world of Concordia into many scattered islands, and it’s up to Mario and Luigi to reconnect them. Venture out on Shipshape Island (part ship, part island) and launch out of its 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.
