With help from Yoshi, the helpful little dinosaur who joins them for the first time, they set out to save Princess Peach from the Koopa King. They'll have their work cut out for them as they travel through nine huge worlds to hunt down Bowser and his evil Koopalings: Wendy O., Iggy, Larry, Ludwig Von, Lemmy, Morton Jr., and Roy. Along the way, Mario and Luigi will ride Yoshi, search for P-Switches, find secret paths, blast fireballs and soar into the skies with the help of the Cape. Their quest won't be easy: Dino Rhino, Chargin' Chuck and a host of unforgettable enemies await in one of the Mario Bros. biggest and most challenging adventures ever.
