One day, Bowser is sitting inside his castle , thinking about how the Koopas have been constantly isolated. He knows that the Toads live peacefully under Princess Peach, and Bowser wants the Koopas to live in peace as well. He then decides to kidnap Peach and force her to sign a peace treaty, but he knows that he can't do it alone, with his Koopas, Hammer Bros. , Spinies , Lakitus , and Buzzy Beetles . He goes to the Goomba Woods and manages to recruit the Goombas to his cause, followed by the Piranha Plants in the Venus Fly Mountains, and then finally, the Bloopers and Cheep-Cheeps of the Sea of Shrooms.
With his army assembled, Bowser sends his forces to construct castles in various locations that will serve as staging areas for Bowser's armies, as well as foundries to construct Bullet Bills, Warp Pipes , and Firebars. Several Toads attack one of the foundries, and Bowser has to fight them off. After that, Bowser is told that they need an ore known as Flamarium to power Firebars, and Bowser has to go get it from Dark Land himself. He ends up fighting a Magmaargh for it. He eventually obtains the Flamarium, but he is impressed with Dark Land so much that he vows to build a castle there eventually. Upon returning, Kamek tells Bowser that he is training a group of seven Koopas in the magical arts, which Bowser approves of.
Bowser then decides to begin his war against the Mushroom Kingdom. He attacks the town of Shroomport, and ends up fighting their mayor.
