Cart Surfer is a mini game found at the mine. If you are playing Cart Surfer at ClubPenguin the faster you go, the higher score you get. To go as fast as possible you need to change your color to lime green. Go to the sports shop and buy the lime green color before playing Cart Surfer and you will have higher scores. To make the most points switch between doing Back flips (worth 50 to 100 points and done by pressing your down arrow key and then your space key) and Hand stands (worth 40 to 80 points and done by pressing the up arrow key twice).
