Just a few more to go.

INVINCIBILITY:
This is the best item to get in the game. While in effect, the user is completly invincible, along with a noticable increase in speed and handing. Any object that comes in contact with the user is destroyed, and other drivers flip over if they touch the user.

Tips-
-Use this item to cut across grass and dirt while mantaining a constant speed.
-Be careful on open sided tracks, you might not be used to the change in handling. It is easy to fall off while invincible.

BULLET BILL:
This item can only be obtained if the driver is in or near last place. While in use, the driver is transformed into a bullet bill and flies down the track at incredibly high speeds. Any driver hit by the user is flipped over.

-When an opponent uses it, be careful to stay out of their way.
-If you use it, use caution on open sided tracks. You are transformed back into a racer without warning and you could wind up shooting off the side.

LIGHTNING:
The last item, lightning, is a very effective way to get ahead in the race. When used, all racers other than the user are struck by lightning, and shrink to less than half their original size. While under the effect, speed is cut in half, and it is very easy to be bumped. The effect wears off starting from last place to first.

Tips-
-Since lightning causes you to lose your item, try to keep an eye on the bottom screen to see if someone has it.

Well that should be all of them. If I forgot any please let me know.
