Tom loves Granny McColl and her house full of animals but he does not love her knitting. Tom thinks that the last thing he wants is another bright and badly knitted jumper for Christmas.  All Tom wants for Christmas is a pet of his very own. Tom is longing for a pet and has shown he is ready to take care of one, but has anyone else noticed? Granny is knitting furiously and mum and dad are busy rushing around.  It’s Christmas Eve and the snow is starting to fall, can a warm wooly jumper turn out to be the best gift of all?
