Winx Club: Season 7, Episode 3

7 - 3: Butterflix

Kalshara, a junior fairy with very dark intentions, manages to have access to an old hall of Alfea College, where wild magic resides and is turned into an aggressive, animal-like shapeshifting creature. By crossing a source of wild magic, she becomes a shapeshifting animal-like creature. She then cruelly transforms her clumsy brother, Brafilius, into a similar creature and is the first one to be on the move with Kalshara to find the fairy animal who possesses the ultimate power, which will give her total control over all fairy animals. Roxy and the rest of the Winx girls manage to rescue the digmoles. As reward for their heroism, the Winx achieve the Butterflix transformation and return to the present.
