Season 7 of Winx Club carries on the theme of recent season by carrying a strong environmental message. In this adventure, the fairies discover the importance of the Fairy Animals, which they must save from Kalshara, an evil shape-shifter and her clumsy brother, Brafilius. The theme of endangered animals recurs throughout the series as the Winx establish an Animal Rescue Park on Earth, where they look after vulnerable animals such as pandas and tigers. The girls also undertake missions in the Magic Dimension and Earth to raise public awareness about the animal cause. This builds to their final mission – to discover the ultimate power of the Fairy Animals, which can give control over all the animals of the Magic Universe.
