Hidden somewhere beyond the highest clouds is the castle of Destino, a school for very special students. They're the Melowies, little unicorns born with a symbol on their wings and a hidden magical power. The Melowies are required to perform a musical in front of all of Destino. Selene does not want to participate because she made a fool of herself the last time she performed publicly. With a little encouragement from her friends she auditions and wins the role of the moon! A rival Melowy sabotages her performance, throwing green paint all over Selene's costume before the performance. Can she overcome her fears and start singing again?
