I need to get some people for mario kart wii but i dont know how to get them i know that you have to unlock them by the expert staff ghosts but i dont know how to unlock them !!!!!

I REALLY wanna unlock baby daisy in mario kart for wii, but what the websites tell u is confusing. Tell me exactly what to do plz!
EX: Race in all of the races and get 1st in all. (idk i am just using an example) THANX!

i have seen the list many times of how to unlock characters is mario kart wii.. for some reason though i am now getting characters for races played.. example: yesterday i unlocked baby daisy for racing 1950 races and not getting a star rank on all 50cc cups.. can i unlock all the rest of the characters i dont have this way?

I was playing Mario Kart Wii WFC and I saw one player that had a japenese looking bunny as a charactor, and another that had a, well I guess a sexy looking Peach as another. Can someone on the World Wide Web tell me how to unlock these charactors for Mario Kart Wii?
Thanks!

I don’t have a Super Mario Galaxy save file and I don’t have Super Mario Galaxy either. I heard u can unlock her by getting 1 star or more on all retro Cups on Mirror. Is that true? or is it u have to get a 1 star ranking on all the cups on Mario Kart Wii? Plz help. Thnx!
