The King and Queen of Sparks and Bloom's biological parents, King Oritel and Queen Marion, might still be alive. Bloom and the Winx give the search for Blooms family, one last shot. Winx Club 3D: Magical Adventure (Italian: Winx Club 3D: Magica Avventura) is a (CGI) animated film that was released in Italy on October 29, 2010. The film is a sequel to Winx Club: The Secret of the Lost Kingdom. It was first thought to have taken place right after the fourth season. Since Roxy, the fairy of animals, does not appear at Alfea or is mentioned in this film and Nabu appears even though he died in Episode 24 of Season 4, it is now thought that the film takes place sometime in the middle of Season 4.

At Alfea College, Stella, Aisha, Flora, Musa, and Tecna all graduate and become fairy guardians of their home planets. But, Bloom must watch graduation from the sidelines. The Winx try to save Bloom's parents and the planet.
