Father Christmas and the Missing Magic Sack

Father Christmas is nearly ready for the big night. The Reindeers Magic Flying, Fly Berries are ripe. Its Christmas Eve but his Magic Sack is too heavy to carry across all those roof tops and to wide to go down the chimneys. Father Christmas leaves the heavy sack in the snow and goes to seeks help to carry the heavy sack back up the hill from the Elves. One Elf (Snaughty) nearly ruins Christmas with a idea! He will fly the reindeer, sleigh and the Magic Sack back up the hill to Christmas House himself, to help save time, which may end in happy consequences?
