Instructions
Go to your Igloo and take your black Puffle for a walk. Go to the Mine and begin a game of "Cart Surfer." Hold either the "Left" or "Right" arrow button down while riding the cart until you start to wobble. Release whichever button you were holding to regain your balance and earn the "Great Balance" and "Puffle Power" stamps.
Press the "Down" arrow key, then press either "Left" or "Right" to perform a grind. You need to perform these grinds around corners; approaching corners are signaled by yellow arrows along the wall indicating the direction of the turn. Grind around eight corners to earn the "Mine Grind" stamp.
Press the "Up" arrow key, then press either "Left" or "Right" to perform a surf move. Surf around eight corners to earn the "Surf's Up" stamp. Press "Down" and then "Space" to perform a back flip. This has to be done on a straight section of the track because you'll lose control if you try a back flip while going around a corner. Perform 20 back flips during one run to earn the "Flip Mania" stamp.
Perform any 20 tricks while riding with the black Puffle to earn the "Ultimate Duo" stamp. Press the "Down" arrow key twice to walk on the rails. Do this 10 times in one run to earn the "Mine Mission" stamp.
Perform 14 different tricks in one run to earn the "Trick Master" stamp. Possible tricks include: Press "Space" to jump; "Up" and "Space" to perform an ollie surf jump; "Space" and "Down" for a slam cart jump; "Up" twice for a handstand; "Space" and either "Left" or "Right" to spin in the air; "Down" and either "Left" or "Right" to do a surf lean; "Space" and "Up" to do a flying and flapping move; "Left" or "Right" to lean; "Up" and either "Left" or "Right" to slide; and "Down" for a wheelie. Do all of these tricks along with the tricks listed in previous steps to earn the stamps for "Trick Master" and "Mine Marvel."
Collect 350 coins in one game to earn the "Cart Pro," "Cart Expert" and "Cart Master" stamps. Coins are earned by performing any of the tricks listed in previous steps, with more coins awarded if you perform a variety of tricks.
