Bloom, Musa, Tecna, and Flora are four magical girls who attend the Alfea sorcery school and together form the Winx Club. When their good friend, Princess Stella of the planet Solaria, is transformed into a hideous monster by her evil future step-family--at Stella's own Princess Ball, no less--it's up the Winx girls to save the day. What they didn't count on was a surprise visit from the nefarious Baltor. This exciting 13-episode story arc kicks off WINX CLUB's jam-packed third season.
