Since the Winx already have the power of Believix and Nabu appears alive even though he died in Episode 24 of Season 4, it is thought that the film takes place sometime in the middle of Season 4.
Sejak Roxy, peri hewan, tidak muncul di Alfea atau disebutkan dalam film ini dan Nabu muncul meskipun ia meninggal di Episode 24 dari Season 4, sekarang berpikir bahwa film berlangsung kadang-kadang di tengah-tengah Season 4.
