In 4Kids version, when Stella is describing all of the schools to Bloom, Musa gets a cameo appearance (she is sitting at one of the Alfea tables) and two of the witches in Cloud Tower are wearing almost identical outfits to Bloom and Tecna.
In the original version, there is a scene where Mitzi complains about the noise from the fight, but it's edited out in the 4Kids version.
Stella's appearance was inspired by actress Cameron Diaz, according to Iginio Straffi, the creator of the Winx Club.
Some scenes of the Gardenia fight from this episode appear in 4Kids version of opening credits. The scenes, however, appear to have a completely different background which is either just a 4Kids edit or an old version that ended up unused in the aired episode.
