Mavilla thanks the Winx and Roxy for their intervention in the Fairy Animals' exhibition, and asks them if they are from another school. The Winx are hesitant to reply so as to not let Mavilla know they are from Alfea of the future, but Roxy proudly answers by saying they are from a place where all Fairy Animals live free in their natural habitat, insinuating Mavilla's teachings are immoral. Mavilla rebukes her saying that their program is based on the Tome of Nature, a book that contains all there is to know about Fairy Animals.
