There are many different things you have to do to unlock EVERYTHING on Mario Kart Wii. You have to complete some cups in first, second, or third place. Also you have to do some Nintendo online racing to unlock things like the Mini Monster Kart (For smaller characters) also you have to unlock some expert staff ghosts and do many other things. There are some very good websites if you look it up online. Good Luck!
You have to win all of the trophies from each place. You probably have to keep getting first place. I'll ask my friend because she unlocked all of them.
