Deep in the Glade of Dreams, the hero Rayman, his best friend Globox, and two Teensies are relaxing when their loud snoring accidentally disturbs a grumpy old granny in the Land of the Livid Dead. In retaliation, she unleashes a horde of Darktoons and other wicked creatures that spread across the world, capturing its little Electoons, imprisoning the nymphs, and plunging the once-peaceful land into chaos. Roused from their nap, the heroes set out to undo the damage. Their quest to rescue the Electoons and free the nymphs will take them across the many strange and colorful lands of the Glade.
