Celeste lives on Houseboat Pig with Vivaldi the flute playing cat. In this enchanting story they meet a very strange looking bird who is not quite what he seems. Vivaldi plays a lovely tune on his flute then tells them about lots of different animals.
One evening Celeste's friend Arthur the sailor asks her to look after two pretty lovebirds for their owner Mrs Clacket. Vivaldi plays a tune that sounds just like a bird and Celeste gets a lovely reward from Mrs Clacket.
Celeste's cousins have come for a visit and they've brought their train set. Vivaldi plays some train music then they go to the park, swim and have tea but the littlest cousin is only a baby and she just sleeps.
