Mega Mushroom: Mario Kart Wii: Turns you into a mega-sized racer, meaning you can squish everyone for a limited time. Mushroom: Super Mario Kart: Gives you a speed boost when you eat it.

Super Mario Galaxy 2 improves over the original in every way - a task we didn't even think was possible - to create not just the best Wii game available, but one of the best Mario games of all time.
