Codename: Kids Next Door is a 78-episode American animated television series created by Mr. Warburton and produced by Curious Pictures. The series debuted on Cartoon Network in the United States on December 6, 2002, and ended on January 21, 2008, with the special episode, "Operation: I.N.T.E.R.V.I.E.W.S.".[1][2] Warburton originally pitched "Diseasy Does It", his Hanna-Barbera-produced short for a series titled Kenny and the Chimp, with "Those Kids Next Door" planned as recurring characters. When the plot was refined to have the "Kids Next Door" as main characters, Warburton created "No P in the OOL", a series pilot produced by Cartoon Network Studios.
