13 years after the original series, Timmy Turner has grown into a 23-year-old man, but maintains a lifestyle of a 10-year-old to keep his fairy godparents, Cosmo and Wanda, and his godbrother, Poof. Timmy's refusal to mature greatly irritates his parents, who desperately encourage him to move out so that they can sell the family house and travel the world; and Jorgen von Strangle, the chief instructor of the Fairy Godparent Academy, who schemes to entice Timmy into giving up his fairies. One day, Timmy reunites with Tootie, a childhood acquaintance who had an obsessive crush on him for years. Once a socially awkward child, she has grown into a beautiful activist, causing Timmy to fall for her instantly. After Timmy secretly uses wishes to help Tootie protest against the felling of a historic tree, Cosmo and Wanda desperately try to repel Tootie, afraid that Timmy is outgrowing them. Timmy is torn between his love for Tootie and his desire to keep his fairies, which culminates in his hesitating to kiss Tootie. Annoyed, Tootie leaves him, telling him to be more mature. Meanwhile, Timmy's fairy-obsessed schoolteacher Denzel Crocker teams up with oil tycoon Hugh J. Magnate, Jr., to kidnap Timmy's fairies and use their magic for their own gain. Magnate deceives and kidnaps Tootie while Crocker captures Cosmo, Wanda and Poof, imprisoning them in a device programmed to use their magic to grant anybody's wishes. However, Magnate betrays Crocker, wishes he falls into a bottomless
ballpit, and tortures the fairies by adjusting the wish-granting machine to electrocute them each time a wish is made. Timmy tracks down Magnate at his headquarters, which resembles a children's entertainment center, to rescue his fairies and Tootie. He battles both Magnate, who apparently had a troubled relationship with his father and suffers from his own maturity issues, and a toy robot brought to life with the fairies' magic. Timmy saves his fairies from being destroyed by Magnate as he tells Tootie he loves her and kisses her, but in doing so, loses ownership of his fairies, who disappear out of containment. Magnate childishly laments losing his source of magic before his secretary Janice inadvertently incapacitates him. Although Timmy is saddened by Cosmo, Wanda, and Poof's departure, he is happy to be free to finally pursue more mature endeavors, as he had longed to do. Jorgen returns to inform Timmy that, because of his courage, a new law was passed in Fairy World that will now permit him to keep his fairy godparents as long as he only makes unselfish wishes to help others. Tootie, Timmy, and his fairies form a charity organization to grant wishes that will mend all of the world's problems or travesties, flying away in a magical van, which turns around in midair and flies towards the camera. Magnate is sent to a mental hospital after claiming that fairies exist, and Janice becomes the new CEO of the company, turning it into an environmentally-friendly enterprise. Crocker finally falls out of the ball pit onto the Turners' front lawn, where Mr. and Mrs. Turner are "vacationing" to celebrate Timmy moving out, and frustratedly walks away. ==Cast==
