A baby plays in the sand and falls asleep on his sandcastles. A bird then steals his beloved blankie.
Upon waking, the baby is not happy at all to have lost his blankie. He is offered plenty of others, but a blankie is irreplaceable!
He sets off on a quest and faces three trials that will help him grow up.
Finally, to everyone's delight, he finds his blankie, so white, so soft, and unfurls it as a sail for a new imaginary journey.
