Complete 20 multiplayer challenges with bandages
In order to do this you will need to find a cosmetic clinic that will give you a nose, lip or any other face jobs available, now you need to have enough money on you in order to pay for it. Once it's done you will get bandages around your race, now all you need to do is start a race against another player and finish it 20 times. However the bandages will come off after a short period of time, if you are lucky you can get 2-4 races in before they do.
After you have the bandages press to go to the big island map and go to 'Multiplayer Challenges', now press to try and get a match quickly.
I never did that one, but I would imagine it would count.
