* ProductDeliveryOrdeal: In one episode, Numbahs 2 and 3 have to deliver a large truck full of soda to its destination without being shaken up. [[spoiler:Turns out the truck contains a cake for the Delightful Children from Down the Lane.]]

The show has two {{Licensed Game}}s, ''VideoGame/OperationVIDEOGAME'' for consoles and ''VideoGame/OperationSODA'' for the UsefulNotes/GameBoyAdvance. The series also appeared in two MassiveMultiplayerCrossover games: the ''VideoGame/FusionFall'' MMORPG, with various characters from the show serving as [=NPCs=], and the fighting game ''VideoGame/CartoonNetworkPunchTimeExplosion'', with Numbuh One, Father and the Toiletnator appearing as playable characters.

** One possible example is Mr. Frybingle, Numbuh 1 and 2's history teacher from Operation A.R.C.H.I.V.E., whose actions appear to imply Nigel's insane, conspiracy-heavy report is actually true.

* CivilizedAnimals: Oddly common. Well-known examples include the KND hamsters, Bradley/Numbuh 6, the chicks from "Operation: C.A.K.E.D.-T.H.R.E.E." and the shark family from "Operation: F.A.S.T.F.O.O.D."

** The true scale of the [=KND=] itself only became clear in the later half of the first season. Before, it was implied Sector V ''was'' the [=KND=] as a whole. Related to this, Chad's actual role as KND's leader was something added only in Season 2.

* ContinuityDrift: The first season finale, "Operation: G.R.O.W.-U.P.", seems kind of off after viewing later seasons. Instead of getting decommissioned, Nigel just leaves the group and gets a job with his memories intact. It stands to reason that they had no reason to go after him. By the system he was still 10 years old and it wouldn't have alerted the decommissioning department. (That, combined with the fact that Numbuh 86 hasn't been introduced yet.) None of his team would report him, either, so as far as anyone outside his team knew, nothing had changed.

* TriageTyrant: In the episode [[Recap/CodenameKidsNextDoorS3E12BOperationHOSPITAL "Operation: H.O.S.P.I.T.A.L."]], Sector V has to get into a hospital to rescue an injured operative [[spoiler:who later turns out to be Bradley]] because operatives who are treated there are being assaulted. Numbuh One has no luck with the triage nurse; even though she seems friendly and harmless, she doesn't take his authoritarian demands seriously. Numbuh Five, who is more polite and often the OnlySaneWoman of the team, is luckier and gets some information, but is still unable to get them admitted formally. Despite this, seeing as AdultsAreUseless in this cartoon (the ones who aren't evil, anyway), sneaking in is surprisingly easy, and no one tries to stop them. Lucky thing too, [[spoiler:because Bradley ''is'' targeted by the assailant, who happens to be Numbuh Five's evil sister Cree.]]

* CivilizedAnimals: Oddly common. Well-known examples include the KND hamsters, Bradley/Numbuh 6, the chicks from "Operation: C.A.K.E.D.-T.H.R.E.E." and the shark family from "Operation: F.A.S.T.F.O.O.D."

* FunnyAnimal: Oddly common. Well-known examples include the KND hamsters, Bradley/Numbuh 6, the chicks from "Operation: C.A.K.E.D.-T.H.R.E.E." and the shark family from "Operation: F.A.S.T.F.O.O.D."

''Codename: Kids Next Door'' (2002-2008) is an [[Creator/CartoonCartoons original animated series]] from Creator/CartoonNetwork about a team of five ten-year-old 4th-graders who are members of an international organization that fights adult tyranny. It was created by Tom Warburton (credited as Mr. Warburton).

* [[SequelEpisode/CodenameKidsNextDoor Sequel Episode]]: Plenty of [[SequelEpisode these]] to go around, they might as well be {{Story Arc}}s.

Those five kids are Sector V, a FiveManBand in the worldwide organization known as the Kids Next Door: [[TheLeader Numbuh One]] (Creator/BenDiskin) is a ProperlyParanoid ConspiracyTheorist who is always seen wearing sunglasses (and has no hair); [[TheSmartGuy Numbuh Two]] (Diskin) is a pilot and inventor known for cracking {{pun}}s at inappropriate times; [[TheChick Numbuh Three]] (Creator/LaurenTom) is TheHeart of the team, constantly happy and serving as the team medic; [[TheBigGuy Numbuh Four]] (Creator/DeeBradleyBaker) is a BookDumb kid who holds an invaluable amount of street smarts and serves as a combat specialist and the team's enforcer; [[TheLancer Numbuh Five]] (Creator/CreeSummer) is [[OnlySaneMan the only sane girl]] trying desperately to keep the team together.

** Numbuh Three[=/=]Kuki, "[[TheChick The Flirt]] / TheDitz" -- Green

** In "Operation: H.O.T.S.T.U.F.F.", instead of the show's normal intro, the episode begins with Kuki's father sternly telling her not to turn up the thermostat (even though the house is freezing cold). In other words, a literal ColdOpen.

* NoPronunciationGuide: Invoked by Numbuh Two in "Operation: R.O.B.B.E.R.S." He constantly feels the need to point out "victuals" spelling is different from its pronunciation, "vittles".

* [[FourTemperamentEnsemble Five-Temperament Ensemble]]: Numbuh One = Melancholic, Numbuh Two = Supine, Numbuh Three = Sanguine, Numbuh Four = Choleric, Numbuh Five = Phlegmatic.

* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Numbuh One = Melancholic, Numbuh Two = Supine, Numbuh Three = Sanguine, Numbuh Four = Choleric, Numbuh Five = Phlegmatic.

* AsianAirhead: Kuki Sanban (a.k.a. Numbuh Three) is effectively like a younger, prepubescent [[WesternAnimation/{{WITCH}} Hay Lin]] (ironic, considering Kuki's [[Creator/LaurenTom voice actress]] also voiced Hay Lin's grandmother). An adorable, girly, kindhearted, rather prissy girl who is personified as being extremely scatterbrained. Website/ThatOtherWiki says that [[ObfuscatingStupidity she is only acting stupid so she doesn't feel sad]].
