Mario, Luigi, Toad and Princess Peach find their way lost in the middle of the thought-to-be destroyed kingdom of Subcon, a desert country connected between the Mushroom Kingdom and Sarasaland. The four friends must help a new ally, Prince Imagin (Daisy's cousin) to take his land back from King Wart, and his alien second-in-command Tatanga, along with Mario and Luigi's no-good cousins, Wario and Waluigi. Meanwhile, Princess Daisy, and Toadette set out to find their friends with help from a new ally, a hungry dinosaur named Yoshi.
