Here is part 4. I should have all the parts done shortly.

TRIPLE MUSHROOM:
This item works the same way as the single mushroom, exept you get three of them. Use this when taking longer shortcuts that need more than one boost.

GHOST:
This is probably the next best powerup after invincibility. Not only does it make the user invisible, but while it's in effect, the driver is invincible and steals an item from a nearby opponent.

Tips-
-Similar to how invinciblity works, you can cut right across grass and dirt, and go right through items. This makes it a valuable item to have.
-If an opponent is using this item, they might try to steal your item if you are nearby. You can avoid this by using your item right away.

BOMB:
This useful item has an effect similar to the spiny shell. Within seconds of its use, it explodes and creates a large blast that sends the racer into the air. However, they can be a pain to shoot, because they fly so far and it is hard to aim.

Tips-
-When an opponent is close behind, drop the bomb directly in the path of the other driver. If done a particular way, it can be a certain hit.
-Drop it in a narrow space. When the track thinner and has less steering space, drop it and it becomes almost impossible to dodge. A good track to do this at would be Choco Mountain, since there is little space at certain parts.
