If you mean by gaining a Mega Mushroom or growing to a large height, you cannot. You are able to in Mario Kart Wii.
I last played on 'Mario Kart Wii' about 2 months ago, but from what i can remember, they are them big sliver blocks that float in the air. And when they see you coming, the drop down to try and crush you. They are in alot of maps. For example Bowsers Castle.

To unlock a big vehicle, first you have to have a big character. All the big characters out there areRosalinaBowserDry bowserFunky kongWarioWaluigiDonkey kongKing booThey all come with big cars and bikes. To unlock the bikes and cars, you have to do different acheivements such as get a rank star on a race or at least get into first place. You may have to get all stars in retro cups or in wii cups.If you have unlocked the mirror grand prix, you have even more to unlock!
Go to You-tube.com they have videos that show you how to unlock characters for Mario Kart Wii. (Note:There is 1 secret hidden character and that's Roselina to unlock her you need a save file on Super Mario Galaxy.) Haha!just kidding to get Roselina you have to beat star cup, special cup, leaf cup, and lightning cup MIRROR MODE and get STAR RANKS on all of them. ITS LIKE IMPOSSIBLE. if not do the first option but at least try. I got it. And this last paragraph is wrote from a different person than the first few sentences of the answer. By the way Roselina is a big size character.
the only way is to moonjump(hack\cheat)
no, unless you have cheats for that game
Go on the Mii Channel on the Wii home Menu and edit your selected Miis size so that he is quite big and then go back on to Mario kart wii and look at your mii. He or she will be an adult mii.
When you start the big bully level star with a rocket boost then when he's at the edge use a mushroom to knock him down.

Depends on the type. If you're talking about the shortform for Super Mario Kart, they either don't sell anymore or are at a flee market. MK64 and MKSS(GBA Mario Kart) have probably the same condition. MKDD(GCN Mario Kart), MKDS, and MKW sell at low cost stores like Gamestop and MKW and MKDS sell at Big stores like Wal-Mart. Not so sure about MKDS though.
