With her fairy staff Astrella wishes herself every night to the sky. There she counts and cleans the stars sparkling and sings her wonderful song. But the starry fairy can much more: She can conjure the sun, the moon or even a rainbow to the sky, in addition to continue to stop the rain with her singing and knows so much to tell about sun, moon and stars.

Sometimes, however, something goes wrong with magic, but then the knight Konrad comes to help, who accompanies her on the grand piano. Thanks to the energetic support of the young audience, the dilemma is quickly resolved.
