Season 0 of The Fairly OddParents refers to a collection of cartoon shorts on the Nickelodeon programs Oh Yeah Cartoons. The Oh Yeah cartoons series ran several cartoon shorts from in the late 1990's through the early 2000's as a type of "test run" to see how Nickelodeon's audience would respond to the cartoons. The Fairly OddParents was one of three cartoons which were green lighted for a regular series, the other two were I Was a Teenage Robot and Chalk Zone.  The Fairly OddParents shorts aired from 1998-2001. When FOP became a regular series, 8 of the 9 cartoons were "repackaged" as "three shorts episodes" and ran along with the regular series for about 2-3 years. This was undoubtedly due to the fact that FOP had so few episodes.  The Oh Yeah shorts introduced many of the characters that are still on the show such as Timmy Turner, Cosmo and Wanda, Mr. and Mrs. Turner and Jorgen Von Strangle
