Beginning of the Guide. Goes, of course, from the beginning to the start of Koopa's Cruiser.
When it comes to beating the stuffing out of the bad guys, no one in the Beanbean or Mushroom Kingdom does it better than Mario Mario. When Mario learns of Princess Peach's predicament, he accepts Bowser's offer of transportation aboard the Koopa Cruiser and rushes off with his brother, hot on Cackletta's heels. However, Mario and Luigi will soon find out that not everything is as it seems out in the Beanbean Kingdom wilds.
Luigi Mario is Mario's brother, and the two share in the epic adventure. Although not quite as brave as his big brother Mario, Luigi has a heart of gold and is always ready to lend his brother a hand.
Princess Peach is the kind and noble ruler of the Mushroom Kingdom, adored by all of her Toad subjects. Peach's voice is stolen at the beginning of the game by the evil witch Cackletta, and replace with a highly dangerous, explosive vocabulary. Unless Mario and Luigi find a way to return her voice, Princess Peach must live out her days in silence.
Bowser is the brutish King of the Koopas and longtime enemy of the Mario Bros. His two main goals in life are to capture Princess peach and cause Mario and Luigi no end of trouble. Although he assists the Mario Bros. in reaching the Beanbean Kingdom by allowing them to board his speedy Koopa Cruiser, Bowser's true intention is to kidnap Princess Peach as soon as Mario and Luigi find the cure for her explosive voice.
The Great Cackletta fools Princess Peach at the beginning of the game, posing as the Goodwill Ambassador from the Beanbean Kingdom to get close to the Princess and steal her voice away. It is unclear why Cackletta would want to steal Princess Peach's voice, but there's no mistaking that her intentions are not good. Mario and Luigi set off to the Beanbean Kingdom in Bowser's Koopa Cruiser hoping to catch up with the evil, voice-snatching Cackletta.
Fawful is Cackletta's loyal servant and is perpetually found by her side. Skilled at making thoroughly evil devices, such as the one he used to steal Princess Peach's voice. Fawful would do just about anything to gain favor in the eyes of his evil mistress. Fawful is no fool, although he'd be nothing without Cackletta's guidance.
Toadsworth is an elderly Toad who does his best to keep Princess Peach out of harm's way. Loyal subject of the court of the Mushroom Kingdom, and trusted friend of Mario and Luigi, it is Toadsworth who gives Mario the most important item he'll ever receive-the Suitcase. Toadsworth pops up frequently over the course of the adventure to offer guidance and words of wisdom.
