As I played Mario Kart Wii last night I saw that in Wario's Gold Mine there was a secret path that boosted you 3 places ahead. The path is hard to see when you play. When you go into the cave and launch into the air you will see the purple track that the carts full of gold are on. As soon as you can follow on that purple track all way out. You will land on a secret path after you jump off the purple track. This isn't the only secret path there are so many.
Another secret path is in Daisy Circuit. This one is extremely hard to see but it boosts you forward 4 places. It's a pink house with stairs in the middle that go straight up and out the roof.
There are so many secret paths. I will do one more and continue later on. The last one you should have a boost which is a mushroom or mushroom king. (mushroom but gold with a crown) This one is at coconut mall. When you go up the first escalator go to the right past the down escalator and go into a store on the right side. It's hard to find but you'll get it eventually. Make sure you don't follow the path farther than getting out of the store because it slows you down unless you have the mushroom king.
UNTIL NEXT TIME!!
