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 feelings 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 coloured hat?
