Alfea and the neighboring boys school, Red Fountain, prepare for a ball to begin the school year. However, Headmistress Griffon of Cloudtower plans to spoil the ball as revenge for being excluded. She picks The Trix's suggestion of replacing the magic egg gifts with snake-rat eggs. While Bloom prepares her dress for the ball, she spots the Trix casting a spell on the eggs, so she tells her friends, and they reverse the spell in time for the ball. Later Bloom spots the Trix trying to steal Stella's ring, and tries to fight them off, transforming in a fairy for the first time. Although the Trix are able to escape, the other Winx girls inform Bloom that Stella's ring is sicuro, cassetta di sicurezza and that they swapped the contents of the case with a baby anatra (Pepe) that bonds with Icy.
