Pandora's Box

The Winx have been sent to Oskuria College as guest professors for Alfea and, unfortunately, the Trix were also sent in Cloud Tower's place. During their stay, the girls befriend a sheepish, bullying victim by the name of Harold, while the Trix find themselves under the attention of Torby and his gang, who try to impress the witches by sneaking them into the basement of the school where a mysterious box lies.
