Santa's Coming

Santa on his sleigh races to children who are waiting for his gifts, but he could not foresee that the evil troll can ruin the way in which it will move, and now he has to be very careful to move that would not fall into the abyss which is very deep and get out of it is not turn out! You also have to give orders to the deer that he would have jumped in front of every cliff and jumped to the other!
