Reverse :
First off, become champion on Championship Expert Mode. Now, restart the game and choose Championship, Reverse. You play the game just like on Expert Mode, but, you run the courses backwards!
Change Racers' Colors:
On the character select screen, when you highlight a racer, hold the Up on the Analog Stick and the racer will change to its color (and number) in two player mode!
Instant Power Ups :
At the beginning of a race, hold both gas buttons as the last light beeps. The closer you get to the light, the more power you get.
Extra Points for Stunts :
In stunt mode, right after you do a stunt and the announcer is about to say something, pause the game. If you do it right, all sounds should stop except the announcer's voice, and you'll get a great deal of points even for simple stunts.
Baby Killer Whale:
Once becoming champion on Reverse mode, re-race on the normal circuit. At Southern Island there is now a baby killer whale jumping along side the bigger one.
More Dolphins :
Get into the warm-up mode for Dolphin Park. If you can follow the dolphin for three times around, two baby dolphins will show up. If you can follow for seven rounds, three babies will appear. If you follow around twenty times, a giant dolphin appears.
More Wild Life :
If you have 35 points before you enter Southern Island in the championship mode, you will see Killer Whales. If you have over 45 points prior to entering Southern Island, two baby Killer Whales will show up. If you take first place in every course during championship mode, you will see a penguin on the Cool Wave course.
Shortcut Through Southern Island :
On Southern Island, when the waters all the way up, go to the poles that are sticking out of the water and look for the jump with red and white warning at the bottom. Go off of it at around 110 mph and do a submarine dive underneath the dock. This really helps you out in the time trial.
Win Race:
At the main menu select stunt mode,choose any character,go into any race track,start the race and when ever you do a trick off of a jump press start as soon as you land now when you finish the race you should get tons of points (this trick works best with the double back flip)
