Friendship is the true magic!
PlotStella is busy designing her clothes while some insects enter her room. She screams, shouts and gets out of her room. Bloom, Musa, Tecna, and Aisha are also annoyed by the insects and see that they belong to Flora. Flora summons a Treemans Orchid to lure the insects back to their homes. Roxy enters the room and asks the Winx to help her transform Griffin back to her real form. Flora tells Roxy and the Winx to come to her room where she gives Griffin a potion she made from her plants immune system, the potion looks as though it is working, but it fails and Flora suggests Roxy to ask Professor Palladium for help. Roxy leaves the room after thanking the Winx, when Griselda comes in and informs the Winx that Faragonda has summoned them to the History of magic classroom. There, Daphne and Faragonda tell the Winx about the Legendarium and Eldora, a fairy godmother who used to be the keeper of the Library of Alexandria until it was lost. Daphne also tells the Winx about the Library of Alexandria which is located in Egypt, Earth. She tells that Eldora kept a diary, where all of the secrets of the Legendarium are written. Because of this, Daphne, Faragonda and the Winx plan to go to the Lost Library of Alexandria and reasons out that it is a field trip.
At Cloud Tower, the Trix spy on them and plan to steal the diary from them.In the other side, the students of Alfea, Lorie, Evy and Carol are ready to leave with the Winx while the Trix arrive and Darcy turns them into frogs. The Trix disguise themselves into the three girls. When the Winx, Daphne and the Trix (disguised as Lori, Evie and Carol) are about to leave, the Specialists and the Paladins come to visit Winx and Daphne. Tecna scolds the three of them, so Stormy gets mad and tries to attack her, but Icy calms her down. Stella takes her mini-fan out and creates a strong wind, which the Winx get mad for. Nex and Roy still fight over Aisha, so the Winx, Daphne, pixies and the Trix teleport to Alexandria. In Egypt, Daphne gives trivia about the library and continues to find the library. Aisha finds a hot air balloon, which they rides on to find the library easier. The Trix plan to "have fun", so Stormy creates a sand storm. Bloom uses her magic to save the Winx. Daphne becomes worried, so Cherie stops the storm, which Darcy finds ridiculous. Flora uses her magic to feel the plants and detects them underground. Down there, Flora destroys a big rock and all of them enters it. Icy talks to Selina, who is in Cloud Tower, watching all of them.
Stella, scared, puts her hand on a wall, but discovers the entry and the others congratulate Stella. The Winx come into the library, and are surprised. Everything is full of gardens and palm trees, and Daphne says the Legendarium was between the walls that are in the library, but they do not know where to look because everything is great. The Winx begin to look, but there are thousands of books. Meanwhile, Selina summons some mummies and she orders them to attack the library. The mummies start attacking the team, and the Winx and Daphne transform. The Pixies help the Winx, and a mummy attacks the Trix but Tecna puts them in a cage to be saved. In the cage, the Trix say here they will begin to watch the fight and get to laugh, and the episode ends.
