Timmy is almost a normal child, but only almost. Because the toddler has something very special: two elves named Cosmo and Wanda. Through the magic power of his elves, Timmy experiences the craziest adventures. The Fairly OddParents is an American animated television series created by Butch Hartman for Nickelodeon. The series revolves around Timmy Turner, a 10-year old boy who is granted two fairy godparents named Cosmo and Wanda. The series started out as cartoon segments that ran from September 4, 1998 to March 23, 2001 on Oh Yeah! Cartoons and was later picked up as a series. The series is produced by Frederator Studios and, as of season 6, Billionfold, Inc. For the first four seasons, it was distributed outside the United States by the Canadian company, Nelvana International. Having aired for more than 16 years, The Fairly OddParents is the longest-running fantasy TV series in American television history, and currently stands as Nickelodeon's second longest-running animated series (behind SpongeBob SquarePants). Tired of being a kid, Timmy wishes he could be older in order to go adult things, but his wish backfires when "Da Rules" states that now that he is an adult, Cosmo and Wanda can't grant him any wishes or turn him back into a kid until he is a kid or acts like a kid.
