The Winx are wearing their second/third season civilian outfits from the original Winx Club.
The theme song is a remix of the fourth season's theme song. The new lyrics were written by McPaul Smith.
Bloom's homeworld is referred to by its original Italian name Domino, rather than Sparks (which was used in third-party English dubs).
Stella is now referred to as "The Fairy of the Shining Sun" rather than "The Fairy of the Sun and Moon".
The basic fairy form is referred to as Charmix, not to be confused with the season two upgrades of the same name.
