Sing your heart out this Christmas with a whole choir of characters, in the showstopping new picture book from number one bestselling author David Walliams, illustrated by the artistic genius, Tony Ross! There's more than one star of the show this Christmas. In fact, there's a whole choir of them! Warble the walrus LOVES to sing. Unfortunately, she is not very good at it! And when her atrocious warbling causes an avalanche, the other walruses leave her all alone. But when you SING like no-one is listening, SOMETIMES, they start to hear you.
