A young boy,Timmy Turner, has two fairy godparents, Cosmo and Wanda, who grant his every wish, inadvertently causing problems that Timmy must fix. In the beginning of the series, Timmy's babysitter Vicky was the main antagonist. As the series progressed, more villains were added. For example, his teacher, Mr. Crocker, firmly believes in fairy godparents and has been searching for them a very long time, suspecting that Timmy has fairy godparents. He is dangerous to Timmy because, according to "Da Rules", a large rulebook that defines what children can and cannot wish for and how fairy godparents must behave, nobody else can know about his fairy godparents, or else they will be taken away from him (although he doesn't remember, Cosmo and Wanda were once Crocker's fairy godparents, as the rule doesn't apply to people who currently have their own or once had fairy godparents)...
