Chachi is an elf who wears green and Piruli a fairy who likes mauve. The two are great friends and live in a beautiful forest furrowed by a river. At night, Chachi and Piruli go out in search of dreams: the fairy catches them with a dreamcatcher before they vanish forever. One night, after several adventures and some accidents, they catch a precious dream in which some children bathe in the sea. What a good idea! The next morning, Chachi and Piruli put on their swimsuits and go to the river, followed by the animals of the forest. They swim, they dive, they do pirouettes, but suddenly Piruli realizes that Chachi has turned red, really red, and does not want to leave the water. What will happen to him?
