Pooh's Adventures of Winx Club Season 3 is the third Winnie the Pooh/Winx Club crossover project planned to be made by RatiganRules. It is planned to be made after Bloom's Adventures of Pooh's Heffalump Movie.
Previously banished to the Omega Dimension, the Trix are able to escape with Valtor, an evil sorcerer (whom Brer Fox, Brer Bear, Jessie, James, and Meowth of Team Rocket, Plankton, Pete, Professor Ratigan, Fidget, Jafar, Iago, Maleficent, Scar, Shenzi, Banzai, Ed, and Chernabog work for) partially responsible for the destruction of Bloom's home world Sparks, seventeen years ago. They choose to forge an alliance and plan to invade several areas in the realm of Magix and seek vengeance on those who imprisoned them by stealing their exceptionally strong, magical and mystical treasures and immeasurable power sources of each realm. With their newly strong Enchantix powers, Flora, Stella, Layla, Tecna, and Musa are able to use strong, incredible power and can miniaturize themselves at will. Bloom, however, cannot miniaturize herself due to the fact that her Enchantix is not complete. The Winx (along with Winnie the Pooh, Brer Rabbit, Ash Ketchum, SpongeBob SquarePants, Genie, Simba, Mickey Mouse, Littlefoot, and their friends) begin their third and final year at Alfea, learning about their unique Enchantix transformations, acquired by selflessly sacrificing themselves for someone from their home world (or even everyone from every world, in what ends up being Tecna's case) and showing great bravery and courage in doing so. With no one from her home world to save, Bloom must acquire her Enchantix form and tremendous power on Pyros, the island of dragons. She also learns more about her home world of Sparks, as well as the truth about where her birth parents, Oritel and Miriam, are.
