You don't unlock the New Goblin. You just do the game and later on you'll fight him.
You are not able to play as the new goblin in the regular WII version
If you want to get the new goblin, then go the the spiderman 3 section on the xbox marketplace and download him for i think about 250 ms points. Im not too sure how to unlock him during the game (as he is not automatically unlocked) but i think it might be one of two ways 1)Beat him in the storyline after the download 2) Beat the game after the download Im working on unlocking him now as i have recently downloaded him Good Luck!
u unlock Black suit at very start but there isn't any more costums sadly....iv finished it 5 times but no more costumes

They call it Super Mario Bros Wii for a reason
Do all of the tracks avalible.
Do ALOT of races do the Grand Prix and othre missions to unlock new ones.
First beat 2 cups and you unlock a new cup
Win first place on the cups you already have. They'll unlock the new ones.
there is no goomba to unlock in Mario kart wii
you play it and race. Bit of advice grab a hammer and smash the wii up
