2. Don't use anyone's 3rd kart; the first ones are always more effective.
3.In DK pass when you first start to the side there's a bunch of pine trees. Drive over to where those trees are and you should drie right through them. Then you'll be driving up a hill in which an item box lie on top. Even if you're in 1st place the itembox will give you bullet bill or star or king mushroom. It's pretty cool yeah
4. In rainbow road when you bump into the sides it makes a pretty sound. Hehe. The tip is NOT to get speed bursts cause then you could fall off. You should only get a speed burst if you're looping.
5. In Balloon Battle get an item box. When you get an item box with a mushroom, triple mushroom, or king mushroom in it don't waste it. (Have less than 3 balloons blown up) Find your target, preferably a team opponent. Make sure you're about to bump into them, then use the speed burst. Congratulations, thief! You have successfully stolen a balloon!
