Pipì, Pupù and Rosemary are three little friends in search of Mapà, a mysterious character, both a mother and a father, and the Narrator entrusts them with a delicate task: Mapà composed a score for the Great Concert of Midsummer for all the animals of the Woods but the musical notes disappeared and nobody knows where they are. There is only one way to find them: notes are attracted by music so our three little heroes must play a concert.
