Nintendo DS classic, Mario & Luigi Bowser’s Inside Story, is back for more gut-busting adventures in Mario & Luigi: Bowser’s Inside Story + Bowser Jr.’s Journey for Nintendo 3DS family systems.

Mario and Luigi have been tasked with finding a cure for the blorbs, a disease threatening all life in the Mushroom Kingdom. But, thanks to Fawful, both brothers have been devoured by Bowser!

And so, their journey takes them deep into the belly of the beast, leaving Bowser to scour the kingdom for the cure. The only way forward is to change between the Bros. and Bowser.

The big bad will even beef up for monstrous boss battles fit for a king! Take ‘em down in this action-packed RPG, and find out what happens behind the scenes in the untold story of Bowser Jr.

In addition to the game’s revamped graphics and refined gameplay, a new side story follows Bowser Jr. as he gathers an army, creates formations, supports his allies with an arsenal of moves and generally causes chaos (in the best way possible).
