Leaf through the pages and listen to the story of Rachele, who travels on the back of a dolphin and meets the mysterious creatures of the sea: colorful fish and sparkling jellyfish, mischievous octopuses and musical crabs. Is it a dream or reality? A sound book that comes to life when the pages open: the sound allows those who can't yet read to immerse themselves in the story, while with the pop up the characters come to life.
