yes. for beating one complete horizontal line of cups you unlock the ability for your charachtars to use 7 different carts. for beating all cups you unlock 15cc mirrror where all the turns are reversed. (for beating 150cc mirror you unlock r.o.b.)
You can't. Sorry!
win the 150cc star cup!
win 150cc in the lightning cup, and leaf cup.
you have to beat all cup tour on 150cc
You have to beat the Nitro Grand Prix in 150cc Mirror. That is how you earn R.O.B.
Get one or more stars in all 150cc WII cups
The mirror cup can be played after you complete 50cc,100cc,150cc cups
You get 1st place in all 50cc,100cc,150cc,and mirror mode in grand prix.
The Mirror cup is basically the same thing as 150cc, but the whole place is backwards. So if in the normal 150cc you were supposed to turn right, you would be turning left.
go to 150cc then try it!!!!!!!!!!!!!!!!!!!!(it`s not that hard :D)
You complete all cups by being Mario on 50cc 100cc 150cc and 150cc mirror. Then you will unlock baby Mario
150cc is just a faster engine class for advanced players.
