Codename: Kids Next Door is an 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.".{{Cite web |year=2000 |title=Cartoon Network's Codename: Kids Next Door Challenges Tyrannical Rule of Adults Starting Tomorrow – December 6 |url=http://findarticles.com/p/articles/mi_m0EIN/is_2002_Dec_5/ai_94934182 |url-status=dead |archive-url=https://web.archive.org/web/20090325221916/http://findarticles.com/p/articles/mi_m0EIN/is_2002_Dec_5/ai_94934182 |archive-date=March 25, 2009 |access-date=2009-02-04 |website=Businesswire.com}}{{Cite web |date=February 2, 2009 |title=PR: Codename: Kids Next Door Embarks on Its Final Mission |url=http://news.toonzone.net/article.php?ID=20846 |url-status=dead |archive-url=https://web.archive.org/web/20080928004424/http://news.toonzone.net/article.php?ID=20846 |archive-date=September 28, 2008 |access-date=2008-10-25 |website=Toonzone.net}} 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. The pilot was broadcast in 2001 as part of the network's The Big Pick II event, a marathon of similar pilot shorts resulting in a viewer poll to determine which series should be greenlit for a full series, and "No P in the Ool" won that poll. The series follows the adventures of a diverse group of five 10-year-old children who operate from a high-tech treehouse, fighting against adult and teen villains with advanced 2×4 technology. Using their code names (Numbuhs 1, 2, 3, 4, and 5), they are Sector V, part of a global organization called the Kids Next Door.{{Cite book |last=Erickson |first=Hal |title=Television Cartoon Shows: An Illustrated Encyclopedia, 1949 Through 2003 |date=2005 |publisher=McFarland & Co |isbn=978-1476665993 |edition=2nd |pages=207–208}}

Each season consists of 13 episodes, most of which are composed of two 11-minute stories, making about 26 segments per season. There are also several full-length 22-minute episodes. Each title is in the form of an acronym that gives the viewer clues as to what the plot is. Tie-in media includes comic books, trading cards, toys, and two compilation DVDs released in 2004 and 2005, titled Sooper Hugest Missions: File One and File Two.

However, in their attempt to get the recipe, an ice cream trap was set off, freezing over 5000 KND operatives. It took 10 years to thaw them out, and all were decommissioned since they were technically too old to be KND. All were found except Numbuh 19th Century, the operative sent in to get the recipe and set off the trap, until the current KND recently discovered him. After being thawed out, he's confused by the new modern era, especially with the fact there are now girls in the KND.

|ShortSummary=The enemies of the Kids Next Door, led by Benedict Wigglestein (Father), join forces to resurrect the ultimate evil, Grandfather, a tyrant who once ruled the world many years ago when most of the villains were children themselves. However, Grandfather disgraced him that he cannot even try to destroy the KND and the villains were quickly betrayed when they are turned into Senior Citizombies, creatures that are immortal and can transform any human being or any animal (can use the term: Senior Animal Zombies) into one of them and slaves who are forced to make tapioca to refuel Grandfather so he can find and destroy the Book of KND. Once the villains are zombified (but not the teenagers and babies), Grandfather unleashes his wrath on the world, transforming almost all of humanity into old beings, turning the KND tree houses into tapioca factories, and the Kids Next Door including the Gallagher Elementary School exclusive KND Operatives rallies in defense, but are quickly overrun and zombified. Numbuh 1 is the only surviving KND operative to locate the KND's only hope for salvation, the legendary hero Numbuh 0 who turned out to be Montgomery Uno, Numbuh 1's father. In the process, Numbuh 1 discovers shocking information about the KND, Father and the Delightful Children from Down the Lane, and even his own family. Realizing that he is the only one standing, he makes a daring task to find Numbuh 0 and to save the world.

Guest voice: Neil Ross as Grandfather.

|ShortSummary=While Billy's dad is underwear shopping, Billy, wearing his dad's lucky pants, accidentally rips them with Grim's scythe. Billy opens the door to his house suspecting the Powerpuff Girls, but the portal leads to the Sector V operatives instead. Numbuh 1 disguises as Billy while Billy is taken back to the Deep Sea Lab. Mandy, arriving at Billy's house knowing Numbuh 1 is not Billy, tortures Numbuh 1 into revealing the truth. Meanwhile, the Delightful Children from Down the Lane and Billy accidentally fuse with the scythe's power to create the Delightful Reaper. Mandy takes over the KND by fooling Numbuh 362 along with the entire KND, but Numbuh 5, knowing she is not Numbuh 1, is taken to the med lab. The Delightful Reaper assimilates nearly all of Endsville (including Numbuh 2) and grows more powerful and gigantic. Numbuh 1 and Grim try to get the KND to see the truth, but are imprisoned. Numbuh 5 escapes and finds Numbuh 1 and Grim. Grim and Numbuh 1 fuse with the Bone of Barnacles and become the Skeleton Samurai. Mandy, in her M.A.N.D.R.O.B.O.T. (Monkeys And Nice Dogs Relax On Bellies Of Turtles), fights the Delightful Reaper, and so does the Skeleton Samurai, but they cannot defeat it. Grim finds out that the pants belong to Billy's dad (which are shown to be immune to lasers, supernatural energies and mustard). Mandy is their only hope to defeat the Reaper, but instead she fuses with the Reaper. Billy's dad takes off the pants, and the Samurai Skeleton destroys the Delightful Reaper, freeing all of the assimilated children inside it. Mandy becomes furious with Numbuh 1 and Grim, and escapes to vow revenge. Numbuh 1 is mistaken to be Billy by Billy's dad, who punishes him for ruining his lucky pants, as Billy, on the other hand, disguises as Numbuh 1, causing the KND to throw various objects at him in response to prevent what happened that day.

|ShortSummary=Numbuhs 2–5 as adults are recommissioned by an unnamed, unseen interviewer and tell him what happened to Numbuh 1 on their final mission. They are told by the interviewer that the effects of decommissioning have been temporarily reversed so they could be interviewed regarding their final mission, in which Sector V and the younger Sector W compete in a scavenger hunt, alongside most of the series' characters, to win the Delightful Children's birthday cake. Though behind for most of the hunt, Sector V must aid Sector W when they go too far and try to steal Father's pipe. Numbuh 1 is then introduced to the secret organization behind the Splinter Cell: the Galactic KND, an intergalactic KND that battles adulthood on multiple planets, and that he has been selected to become the first operative from Earth. He is able to say goodbye to both his parents and to Sector V. At the end of the events of the film, it is revealed that after Numbuh 5 eventually resigns as the leader of Sector V once again, she and Numbuh 2 get married; Numbuhs 3 and 4 also get married. The interviewer is revealed to be Father in disguise. The series ends with Numbuh 5 pulling out a KND communicator, hinting that either she or the entire sector are all still KND operatives. She tells Numbuh 1 that they will meet him back on the Moonbase, revealing that they lied to Father about Numbuh 1 never being able to come back.

  • Notes: The events of this special take place after the final episode of the series.
