ItemsIn Maple Treeway, the leaf piles sometimes give you mushrooms that lay on the floor - you can use them well if they aren't in an awkward place to reach.
Also, Throwing turtle shells at the ant-like creatures on some of the roads gives you mushrooms too.
Plus in manual, to hold an item behind you, you press left or right on the control pad.
On Mario Raceway, near the end of the lap, there is a green tube. If you ride on the side of it, you can do a trick at the edge and it will give you speed boost!
Mario Kart Wii is not really an ending game, but you will see a special picture when you get gold in all the cups and classes. That can be an achievement.
