"Christmas Eve was here at last. The countdown clock was ticking fast. But yikes! When Santa turned the key (the reindeer need some help you see). The engine didn't start, it spluttered, That isn't right, the elves all muttered." When Santas sleigh stops working on Christmas Eve the elves all rally round to help. Maybe they could use a slingshot? Or the owls could help? How about polar bears? Will they be able to sort the sleigh out before it is too late? Things are not looking good until one small elf has a bright idea!
