The plumbing brothers return to the RPG world in yet another quirky game with Mario and Luigi: Bowser's Inside Story. Once again developed by Alpha Dream, Bowser’s Inside Story has Mario and Luigi controlling their immortal enemy Bowser from inside his body thanks to a trick by Fawful, who is returning from the first game to take on the role of villain. Specifically, Fawful feeds Bowser a magic mushroom and the King of the Koopas begins to suck in everything around him, including Princess Peach.

There's plenty of the drama and silliness and players will get to experience both thanks to the versatility of the DS. Players can switch between storylines at will. Any actions and events that happen inside of Bowser's body affect the events outside of his body, creating the perfect opportunity for fun puzzles, interesting situations, and lots of silly dialogue.

The simple-to-learn button-mashing gameplay the series is known for returns once again to make battles fun and challenging. Bowser himself will also grow in size, and give players the opportunity to blow into the DS's microphone to simulate his fire breath attack.

The silly adventure will be gracing the DS fall 2009.
