Boulder Canyon: Bell
You will see a bell in Boulder Canyon while racing in your hovercraft. Press (R) button and jump to hit it. If done correctly, a bell should start ringing. If you timed it correctly, some of the other players will be stuck in the water for a short amount of time, and allow you to take the lead. This is especially useful when you are ahead of T.T. in Time Trials mode.

Crescent Island: Shortcut
Although this trick only works with a hovercraft, it is highly effective. In regular adventure mode, go the front of the ship, but do not board the ship. Instead, turn left into the water and go around the ship. You will eventually arrive at the exit of the ship. This is much easier than going in the ship. In adventure 2 mode, turn right and go around.

Darkwater Beach: Ammunition
When you start, go to the is land which is a little bit away from the mainland. There will be a balloon on the island and one on the land. Keep going back and forth to get the ammunition. One balloon is a shot. Two balloons is an accurate shot. Three balloon is ten shots.

Dino Domain: Shortcut
When about half way up the hill (not the flat beginning, but the tightly turning hill), you should see a pillar (about the second or third one that has bushes on the right after it). Go through the bushes and you should enter a cave through the mountain. Get the blue balloon to use until you hit the zipper. If you are close enough to the Boss when you enter the cave, you should get in front of him or close enough to him that you can pass him at the finish line.

Greenwood Village: Shortcut
There is a well in Greenwood Village just before you exit the village enter the tunnels. Slow down and run into the well. You will fall in and get a big shortcut with a zipper about halfway through.

Haunted Woods: Shortcut
After the announcer says "Go", you will see a fountain. Go across with the hovercraft to take the lead and get in into first place. Note: This can be done in tracks mode.

Controlling T.T.
When your are turning with T.T., hold (A) but lightly press the (B). You may have to press (B) a few times before he turns well. Do not hold (B). T.T. should turn very well, making him the ultimate racer in the game. In hover, hold (R) for good turning.
