Lily is helping her mother get ready for Christmas - she makes cards, and puts up Christmas streamers, not to mention decorating the tree, and wrapping up parcels. And in everything she does, she does one special one: 'Just for you, Blue Kangaroo'. And Blue Kangaroo is very touched - he feels very loved, and wants to do something for Lily. One evening, he sitting nibbling his paws, when Father Christmas comes down the chimney, so he asks him what he can do. The next day there is a little blue heart hanging on the tree, and Lily cannot imagine whom it might be for!
