Ando Prime Shortcut:

On any of the Ando Prime Snow levels, do one 
lap as usual. Then, when you come up to the 
starting line, veer off to the left and and 
you should see that one of the tents is open. 
If you manage to go through the shortcut 
unscathed, you should be comfortably ahead of 
everyone else. You can repeat this on lap
three also.
