Super Mario World

During a vacation in Dinosaur Land, Princess Toadstool gets kidnapped, and a spell is cast on the inhabitants of the island. When they stumble upon Yoshi, a young dinosaur, Mario and Luigi learn that Bowser is responsible for the terrible misdeeds. Now, all Yoshis are trapped in magical eggs that Bowser has hidden throughout seven castles. Many hidden paths aid Mario in making his way to Bowser's castle, completing 74 areas, and finding all 96 exits. Discover items, including a feather that gives Mario a cape that allows him to fly or a flower that shoots fireballs, in layers upon layers of 2-D scrolling landscapes. You can even ride Yoshi and swallow your enemies!
