The adventures of the mermaid Alea Aquarius and her friends from Alpha Cru take listeners into a magical world. But even more, they resonate with today's children, as they address topics that couldn't be more relevant: environmental protection, saving the oceans, and sustainable management of valuable resources. In "The Magic of the Mermaids," the friends face an additional challenge: Sammy, a member of Alpha Cru, has disappeared. In their search for him, they encounter not only a carpet of plastic waste but also receive help from the magical mermaids. Narrator: Laura Maire.
