Story:
Mario had a dream in which he climbed a high set of stairs leading up to a door. Once at the door, he opened it, and right there was a vast new land--complete with a tour guide. He pleaded for Mario's help and told him how Wart and his underlings hated vegetables.
Mario had a picnic the next day with Luigi, Toad, and Toadstool. They decided to search inside. There, Mario found the door from his dream; the people were about to get help from the plumber and his friends!
