Faragonda is showing the Winx and Roxy the Alfea Natural Park, where the Fairy Animals from the Magic Dimension live, when a wicked bird of prey abducts the last specimen of Digmole...
In order to find out who the mysterious enemy is and what he/she wants, the Winx have to find another specimen of Digmole and they only have one chance to do it: travelling back in time with the Stones of Memories that Faragonda gave them.
Once arrived at Alfea in the past, the Winx meet Kalshara, an evil fairy who wants to trap the Digmoles with the help of her brother Brafilius. The Winx, however, manage to rescue the Digmoles, obtaining in this way the Butterflix power. Magical!
Kalshara and her brother Brafilius are hunting the Fairy Animals because they are looking for the Animal with the Ultimate Power, which allows to give immense power. The Winx must stop them at every cost...
On the tracks of Kalshara and her continuous attacks to the Fairy Animals, the Winx get to Magix prehistory. There they find Squonk, a cute creature that magically bonds with Aisha.
On Lynphea, the MagiWolves species is in danger! The Winx are off to Flora's home planet...there, Flora also magically bonds with a Fairy Animal: Amarok.
The Winx travel to Medieval Italy where even Musa, thanks to the Butterflix power, finds her Fairy Animal, after saving her from Brafilius clutches: it's Critty, the Quillcat.
Oh no! Kalshara abducts Critty and the Winx are forced once again to chase her. They then arrive to their enemies' hiding place, where the Fairy Animals are imprisoned. Among the Fairy Animals there is also the Shinygreed Shiny that, thanks to the magical bond with Stella, sends away Kalshara and Brafilius.
The Techquirrels, the magical animals from the Zenith planet, are chased by Brafilius. And once again, it's the Winx job to sort things out. Thanks to her power, Tecna manages to magically bond with the Techquirrel Flitter and to save his species.
In the meantime, on the Earth, Roxy founds the Animal Rescue Park for the terrestrial animals in danger. How nice! They'll finally have a place to live in, free and safe!
Emergency from China! Pandas are threatened by a shape-shifting creature. Once arrived there, the Winx find out it's a unicorn under a spell, named Elas. Thanks to the special bonding she gets with him, Bloom manages to break the spell and to rescue the pandas.
The six Fairy Animals that bonded with the Winx find out they are the Keepers of the Ultimate Power and give the Winx the Tynix bracelets, thanks to which the six fairies become tiny and they can explore the magical MiniWorlds.
The Winx continue their battle against Kalshara and Brafilius, in a series of journeys between the past and the MiniWorlds in order to save all the endangered species. The loyal Specialists and Paladins are always next to them.
Kalshara and Brafilius think the animal with the Ultimate Power is one of the Fairy Animals bonded with the Winx. After setting a trap to the six fairies, Brafilius casts a spell making the Winx become kids again. In the meantime, Kalshara tries to capture their Fairy Animals!
After many journeys, the Winx find out the Fairy Animal that has the Ultimate Power is actually at Alfea! It's a diamond Digmole!
Unfortunately, though, Brafilius manages to get the Ultimate Power, which he uses straight away to make the most terrible of all actions...he frees the Winx legendary enemies: The Trix!!! The three witches are determined more than ever to conquer Alfea once and for all. Oh no!
The battle between Winx and Trix is very fierce! The Fairy Animals arrive to help the fairies and decide to do the definite magic and turn into the beautiful Infinite Swan. The Swan absorbs the Ultimate Power defeating all the enemies once and for all!
Hurray, it's time to celebrate! Another incredible adventure ended and all the Fairy Animals are safe thanks to the Winx!
