Santa's fallen sick this winter holiday. Ms. Claus has been cooking some of her most powerful chicken soup, but even that's not powerful enough! Santa won't be able to make his first deliveries until much later than usual -- but that is TOO late. You and other elves have been chosen to help make up for Santa's missed time! Fly over cities and drop presents down chimneys. Maintain a 70% success rate to save Christmas! Watch out for planes - you don't want to crash!
