Race underground or in a spaceship, through a rural farmland or a strange alien planet. \

But don't eat the bananas! Watch for bowling balls, plungers, bubble gum, \
and cakes thrown by your opponents."

compete in one of several Grand Prix, \

and more! For a greater challenge, race online against players from all over the world \
and prove your racing skills!"
