This series follows a young girl who forms a special friendship with the moon, which encourages her to perform good deeds. When she feeds hungry birds on a rainy day, the moon rewards her by granting a wish, allowing her to fly to the moon and read it a story. Later, on a hot summer day, she waters thirsty trees, and the moon grants her another wish, turning her into a fish so she can visit the mermaid’s palace and hear the mermaid’s stories.
