Timmy Turner has never had any reason to grow up since that would mean saying goodbye to his fairy godparents, Wanda and Cosmo, forever! Now 23, Timmy is doing everything to remain a kid--he still lives at home, is still in 5th grade, and most importantly, has never fallen in love! But when the formerly geeky and annoying Tootie returns to Dimmsdale as a stunningly beautiful woman, Timmy might be falling in love, which would mean he's finally growing up! Meanwhile, evil billionaire oil tycoon Hugh J. Magnate plans on tearing down part of downtown Dimmsdale. Will Timmy give in to his grown-up feeling and lose Wanda and Cosmo forever to help Tootie save Dimmsdale? Will he try to remain a kid forever? Will he ever get a different colored hat? Find the answers to these questions and more in A Fairly odd movie: Grow up, Timmy Turner!
