No, the only way you can unlock him is to get a rank star in all 100cc races I'm afraid. (but I've done it so you'll get it soon!)
There is no other way.
You can't
you have to unlock mii a & b then finish special cup on mirror cup then you can unlock him.na im just kiddin you just unlock boo then go to time trial beat the staff ghost for boos stage,but!you have to beat it 1:00 minute if this doesnt work than you must be: retarded,your not doing it right,or go to Mario kart wii.com . then look for the words seceret characters click ti find dry bones and walla it tells you how you unlock him &if that doesn't help then go to rejected cartoons and it gives you an easier way to unlock him hope this helps losers :P

no matter what game system, you unlock stuff in Mario kart the same way. you unlock stuff by winning races, getting ranks, and by doing time trials.

to unlock the special cup is simple. You need to get either 1st, 2nd, or 3rd in all of the tracks you have in Grand Prix! and if you do that on all of them you get a new track such as the special cup! from my own experiance, if you do really good in like the leaf cup and star cup, then sometimes you get a new cart for yoshi, mario, baby mario, peach, and theres a little pink player I have but I don't know her name! GOOD LUCK BECAUSE THE SPECIAL CUP IS HARD! BEWARE OF THE RAINBOW ROAD!!!
Adventure with the other 25 guys on normal 3 lives no continues. He`ll be on VS. MODE! That's a rumour. And Giga Bowser is not playable, only by a Gameshark. And the damage limit is 999%.
The only way to play as Giga Bowser is to use Bowser's final smash in Super Smash Bros Brawl.
