Once upon a time, there were four friends who never left each other, they had too much fun together. For several weeks, however, the gang was terribly bored because it was raining incessantly. Fortunately, they had the fabulous idea of going on a picnic sheltered from the water. They decided to repair a large boat to cross the river and go to the Blue Mountain. Accompanied by several friends, including a weasel, a fox and a wolf, they set off for this new land where they would all be so wonderfully, wonderfully, wonderfully happy! This musical tale will make children laugh like never before. The story is carried by a few well-known traditional songs and a dozen compositions that are as tender as they are funny. Very fine illustrations accompany this joyful and unbridled journey.
