Introduction
There is peace in the Mushroom Kingdom. Mario and Luigi have once again defeated Bowser, and they went to their summer home in an island near the coast of Isle Delfino, and Yoshi and Birdo joined the Mario Bros. and their respective princesses (Peach and Daisy) in their vacation. On the day this story begins, Yoshi, Mario and Luigi were playing Super Smash Bros. Brawl in the house while Peach, Daisy and Birdo were shopping in Coconut Mall. In short, all was well in their vacation. Well, almost everything. See, in Bowser's last scheme, he had really gone too far, so when he was defeated, Toadsworth suggested that the once mighty King Koopa be sent to prison. Not just any prison, though; Toadsworth had said to send him to Shy Guy Prison. Shy Guy Prison was an island far, far off the coast of Lavalava Island. However, only the very worst of villains were sent there, for it was extremely secure, with a million Shy Guy guards to keep very few prisoners inside. But even Shy Guy Prison couldn't retain the anger of King Koopa… or could it?
