Super Mario World's story begins with Mario and Luigi taking Princess Toadstool for a vacation. Like previous games in the series, she is suddenly kidnapped by Bowser and it becomes the goal of Mario, Luigi, and Yoshi to rescue her. However, unlike previous Mario games, which take place in the Mushroom Kingdom and surrounding areas, Super Mario World takes place in a new place called "Dinosaur Land". During the course of the game, Mario and Luigi travel through the eight worlds, defeating the Koopaling in each one. After defeating Bowser, the final boss, at the end of the eighth world, Princess Toadstool is saved.
