''The Ninja Kids'' is a side-scrolling [[ArcadeGame arcade]] BeatEmUp made in 1990 by Creator/{{Taito}}. It received no ports until its inclusion in the ''Taito Legends'' CompilationRerelease in 2005. The story is about an evil sect trying to summon "The Satan" on July 1999 (as foretold by Nostradamus), and only a group of four ninja can stop them.

Pretty standard fare for a videogame, except for the fact that almost every character is a puppet. No, not PeoplePuppets, just regular (?) puppets. Everything about this game is very tongue-in-cheek, though, so it also can be seen as a StealthParody of typical cheesy brawler [[ExcusePlot storylines]] and settings.

!!The game provides examples of:

* {{Acrofatic}}: The fat mafiosi attack by, among other things, cartwheeling over you.
* BloodlessCarnage: Enemies are constantly sliced and diced, heads and limbs are falling, but since everyone is a puppet there's not a single drop of blood.
* BlowYouAway: Sasuke
* ColourCodedMultiplayer
** Hanzo - wears blue and is a JackOfAllStats
** Sasuke - wears yellow and is a LightningBruiser
** Akame - wears red and is a FragileSpeedster
** Genta - wears green and is a MightyGlacier
* ConservationOfNinjutsu: Level four is a great example of this trope. In this level, called "A bad ninja appears!", the heroes take a break in fighting the satanists and instead fight the ninjas from a rival dojo or something. Throughout all the level you fight dozens of ninjas that take a few hits to die, then you get to the boss, which is almost identical to them but is (obviously, being the boss) a lot harder to defeat.
* DemBones: Right before the final boss, the ninjas find themselves in a crypt full of bones underneath an abandoned church. Suddenly some skeletons spring to life and attack them.
* DishingOutDirt: Genta
* {{Engrish}}: Various examples, such as the constant saying of "The Satan" and such lines as "WRETCH! NINJA KIDS!" and "HERE IS A GRAVEYARD OF YOU!"
* EvilIsPetty: Not sure how kidnapping an employee of a fast food store and turning him into a werewolf (1st boss) can help the resurrection of The Satan and/or to bring forth world domination...
* ExactlyWhatItSaysOnTheTin
* FlashOfPain: As a nod to most {{Konami}} arcade brawlers, bosses flash white when hit and [[TurnsRed turn red]] when low on health.
** Large mooks also flash white when hit.
* FollowTheLeader: This game is pretty much Taito's answer to Konami's TeenageMutantNinjaTurtles beat'em up that came up one year earlier and was a smashing success. Let's see: up to four players multiplayer, four colour-coded ninjas that fight with different weapons (although in TNK they're mostly blades), the ability to throw scenery elements against the enemies, plus one of the levels (a burning apartment complex) is remarkably similar to the first level in the TMNT game.
* IncendiaryExponent: The second boss is a living fireball.
* MagicPants: The employee-turned-werewolf at the end of level one has them; also a Magic Shirt, in that he rips apart his clothes when transforming, but still has them when defeated and turned back to human.
* MakingASplash: Hanzo
* MolotovCocktail: Some enemies that look like stereotyped Middle-Eastern terrorists who attack by throwing molotovs. When you defeat them, they [[HoistByHisOwnPetard explode]].
* PlayingWithFire: Akame
* RocksFallEveryoneDies: One of Genta's special moves is named "Rock Fall" and does just that.
* [[RunningGag The]] {{Satan}}: The final boss, drawn in a very serious style that [[NonstandardCharacterDesign contrasts]] with the general wackiness of the game.
* ShoutOut: The third boss is basically the Power Loader from ''Film/{{Aliens}}''.
** Characters from earlier Taito titles like ''VideoGame/BubbleBobble'' and ''KikiKaikai'' appear as background elements (graffiti, pictures...).
* TimeStandsStill: The "Time Stop" ability.
* TopHeavyGuy: The [[GiantMook giant mooks]] are this. DO YOU FEEL OUR POWER, indeed.
* WallCrawl: Seen for example at the beginning of level 2.
* XmeetsY: It's ''SesameStreet'' meets ''TeenageMutantNinjaTurtlesTheArcadeGame'' meets ''GoldenAxe''.
* XRaySparks
* ZombieApocalypse: The graveyard in level five is pretty much this. Level three had you facing them at a construction site.
