Mario and Luigi embark on the adventure of their dreams in a hilarious
action RPG that combines the resort world of Pi'illo Island with the
wild landscapes of Luigi's imagination, where anything can happen. Meet
a host of hilarious characters as you strive to rescue Princess Peach
and help Prince Dreambert free his petrified Pi'illo people from the
bat-king Antasma's curse.

Features:

Spawn hundreds of Luigis that mold into different forms like bouncy
towers, wrecking balls and giant hammers for special attacks or to
pass obstacles.

Poke, tickle and move a sleeping Luigi on the lower touch screen to
alter the dream world on the upper screen.

Master two worlds by switching between controlling both brothers when
battling in the real world and controlling Mario and an army of Luigis
in dream-world battles.

With the Nintendo 3DS system turned sideways like a book, experience
larger-than-life Giant Battles with a gargantuan-size Luigi on one
screen and the enemy on the other screen.

Find new items and gear to customize Mario & Luigi to fit your play
style.

To help players through the adventure, the game offers various support
features, like a Hint System that offers tips on surviving a
particular engagement, or an Easy Mode to make a particular battle
easier.
