Nintendo of Japan have updated their pages with the second competition for June.
From Sunday June 15th 2008, players will be able to go head to head with the world racing backwards with the Mushroom Kingdom's finest mushroom fella, Toad. Taking to the Mushroom Gorge is seems that racers will need to do things in reverse, according to Wii Fanboy.
