2nd click on "level and change it from "camp of Champions" to Alaska.
3rd travel down the slope untill you see the larger sized cliff, press the up arrow to stop then go then stop until you get to the pillow line.
4th once you are on the pillow line, do a 540 to 620 and stop.
5th click edit under the tool bar on the left hand side, and move the cliff you should still be on.
6th click ride under the tool bar and procede to the bottom and once you get to the top,(if you do it correctly) there should be all of the grabs listed below your rider.
