Saving Santa

Santa has a huge problem!    His elves have been working so hard to improve security that they changed some of the codes around the North Pole.....   the only problem is that they have forgotten the codes.   Now Santa's sleigh is locked away, and they need your help to get to it before Christmas is ruined for everyone!  The Elves need to get into Santa's workshop, find all the codes for the locks and ignitions.... and even get past the guard elves.  Help them before it is too late.   Good Luck!
