From GamersInfo.net: "You begin with this lovely, adorable, saccharine planet (the planet Roo) that gets all of its nauseating cuddliness from falling shapes. (I know...just stay with me because the story is for the kids, the game is for you.) The King wants all of the shapes for himself, because as we all know, power corrupts! When he starts collecting the shapes, the poor Roogoos turn into the nefarious Woohoos and everything goes awry. It is your job to ensure that the pieces land safely on the planet.
How you ask? How can I save the poor Roogoos?"
