The Anthem. The Winx try to convince Rumpelstiltskin to give them Musa’s stolen voice. However, he won’t accept anything that doesn’t have high value. Stella mentions the Legendarium Key, which he would graciously accept if offered. Even without her voice, Musa can control the music to save Alfea from the witches. But now they have to choose between Musa’s voice and the key to lock the Legendarium that greedy Rumpelstiltskin wants for his collection of rare magical objects.
