A magical cat, an ice-cream van that makes delicious moon-creams and a quest to bring joy to those who need it most. Mr Hooper and The Cat with the Coloured Tail travel through the countryside in their ice-cream van. They enjoy looking for heart shapes (their favourite game) and making people happy with their delicious moon-creams. But a dark feeling is following the cat. Something is wrong. When the ice-cream van enters the forest, Mr Hooper and the cat realise the heart of the world is in danger. Will they be able to save it? A lyrical fable about love and healing.
