Friendship is the true Magic!
The Winx go to Lynphea College for special training with the Specialists and Paladins, skilled warriors. When Selina sends the Treants to attack, the Winx are stripped of their powers and forced to return to Alfea.
PlotMiss Faragonda calls Roxy to her office. She asks Roxy to determine what the injured crow is trying to tell everyone as she is the only one that can understand animals best. In the Winx's room, the Winx are trying to cheer up the pixies due to their sadness after all the pixies disappeared during the last battle at Pixie Village. Musa uses her music power and makes a pop music through a speaker, she increases the volume of the music until the maximum volume which make the Winx and the pixies frightened. But, Tecna miniaturizes the speaker to reduce the music volume. So, Aisha used her new Morphix power and create Morphix Gym Equipments to make the pixies happy. Then, Tecna's cellphone rings and Kiko is so eager to ask to pick it up. It is Timmy, who invites the Winx to join them at Linphea College for their battle training with the Paladins. Tecna thanks him for the invitation while Flora is so excited to meet her little sister Miele who has just enrolled Linphea College. Before they go, Stella is about to design for the Winx some new outfits with a wild theme since Linphea is the magical kingdom of nature. But instead, she makes the Winx wearing bushy plants, which is too wild. Suddenly, Griselda comes to the Winx's room to check out for the pixies' conditions and Stella hurriedly hides her secret boutique while the Winx disguise as plants. When Griselda leaves, Stella gets creativeness and designs for the Winx the new dresses suitable for their occasion.
The Winx ride on ladybugs to travel to Linphea College and land. When they land, Flora is looking for her little sister, Miele, around the college compound. Then, a few fairies from the college greet the Winx, and Stella gave them her autographs, as she likes being famous. While Flora is looking for her sister and about to surprise her when she finds her, the Winx go to the battle arena to watch the Specialists' training by riding a leaf-shaped ship.
The Winx arrived at the battle arena where they have found the Specialists training. Bloom tells the Winx that Sky and Thoren is in action for their training. Everyone gasps as Thoren knocked his powerful hammer weapon and create an earthquake to hit Sky but Sky manages to overcome it with his laser sword. Stella shouts towards Brandon to tell him that she and her friends are there. Then, Nex is trying to impress the Winx when it is his time for action which makes Aisha irritated, causing Roy to be jealous. Helia comes over and asks where Flora is and Tecna replies saying that she is seeing someone which surprises him. A battle training between Roy and Nex starts but Roy loses and falls down, but luckily, Aisha saves her with her Morphix power to prevent him from falling. After this incident, Aisha is furious with Nex, and tells him that all he is doing is showing off his power.
In the meantime, Flora who was searching for Miele found her around her college and surprises her. Miele was so happy to see Flora and Flora is so surprised to see her little sister has grown up. Then, Flora and Miele chat for a while about Miele's college life. At Alfea, Roxy returns to Miss Faragonda's office as she managed to make the crow talk to her by using vocalisation spells. The crow explains everything to Miss Faragonda about what happened. Faragonda and Roxy finally find out that the Trix have returned and the crow is actually Griffin.While Flora is talking with Miele, they see Cloud Tower floating in the sky of Lynphea. Flora is shocked and about to warn the Winx and the others. Meanwhile at Cloud Tower, the Trix asks Selina whether there are any good legendary creatures to be summoned at Linphea. Selina then summons the Treants to attack by waking them up.
Flora orders the Specialists to stop because something was not right. The Treants wake up and attack Lynphea College. Bloom and the Winx transform to Sirenix form to stop the chaos that is happening by flying up to Cloud Tower. While the Specialists and the Paladins help Lynphea fairies fight the Treants. At Cloud Tower, the Winx fight against the Trix but lose the battle. Bloom then sees a bubble protecting Selina. When they attacked the shield defending Selina, who is protected by the Legendarium, they lose their powers except for Bloom.
The Specialists give the Winx a ride back to Alfea where Faragonda and Daphne are waiting for them. The Winx explains what happened while Bloom is still curious of why she did not lose her powers. Faragonda tells her the reason that her power is made up of an inextinguishable Dragon's Flame and is the source of the Magic Dimension. Bloom then shares her Dragon's Flame power to each of her friends. Faragonda then tells the Winx to keep the share of the Dragon's Flame safe, as it will bloom into a new fairy power/transformation. The Winx are really thankful to Bloom after Faragonda explains this to the Winx.
