Climbing Help: If you want to get first on the tracks where you have to climb really fast or you'll get last place (e.g the Bug Trousers track) then there is a move that will help you up. Keep pressing R (or B+A but R jumps and grapples) and either left+up or right+up (diagnal). If you can climb fast using that technique and you can stay ahead of the other players you will win (unless they catch up to you on the final lap).
Get out of Snow Balls:
This trick will help you not to slow down. There is two ways:
Get Enemies out of Your Way: If and enemy is in your way there is 6 ways to get them out of your way.
Finish the Race if You Are Far Behind: If you are in 4th place, you probably aren't going to finish and you have a heli-grapple then you can use it to get into 3rd or 4th (you can only get into 3rd if the person in 3rd hasn't finished)
Refill Boost Meter: Tap JUMP while on a boost platform to refill your boost meter.
