It was to this mythical, mystical place, Dinosaur Land, that valiant heroes Mario and Luigi traveled for a well-earned rest.

Our heroes set out apace to search the foreign land far and wide for their friend, the problem-plagued princess. Together, with their new dinosaur pal Yoshi, who his on his own quest to rescue his friends that are trapped by Bowser, they begin their selfless journey. Their journey will take them to places such as the vast and varied Donut Plains, the intimidating, tower-like Cookie Mountain, and the deep, dark Chocolate Island. Thus their adventure begins.
