Their journey is lit by a huge full moon As it floats in the sky like a giant balloon. This story takes the form of a poem about a young boy called William, who dreams of Santa's crazy rush to deliver presents for William's Mum and Dad and his dog, Tessa. Along the way Santa has a few hitches but William finds out about the very first Christmas and why we give gifts at this time. William is shown to be a kinds and thoughtful little boy who lives up to the spirit of Christmas.
