Yet another of Creator/FujikoFujio's innumerable {{manga}} co-productions, ''Chinpui'' is basically ''Anime/{{Doraemon}}'' for girls. Most of the former's cast are replicated in some form or another, right down to a [[{{IdenticalStranger}} lumbering Gian lookalike.]] The main difference is that the "hero" is a girl and the [[{{RobotBuddy}} Magical Helper]] is an extraterrestrial mouse (as opposed to a robotic cat).

Eri Kasuga is a high spirited Japanese {{Tomboy}} who -- for totally inexplicable reasons -- has been chosen to marry Prince Lulealv of the Planet Mal. In light of this momentous occasion, two envoys have been sent to Earth to announce the upcoming betrothal: Chinpui, an oversized, wish granting mouse; and Wandayuu, a lethally annoying talking dachshund. Like most of Mal's [[FunnyAnimal anthropomorphic population,]] they can perform miracles by simply [[{{MagicalIncantation}} shouting their names]] (with the usual disastrous results).

Needless to say, Eri is none too thrilled with the prospect of marrying an alien she's never even met, particularly since she's only eleven years old (in addition, she already has a "[[JustFriends sort of boyfriend;]]" Uchiki-chan, the [[NiceGuy quiet]] [[TheSmartGuy smart kid]] who lives down the road).

Faced with this overt rejection, Wandayuu departs to discuss the situation with the Royal family, leaving Chinpui behind to serve and protect "their future princess." While Eri initially regards Chinpui as a nuisance, he soon proves himself a loyal and trustworthy friend, especially when it comes to solving the inevitable problems caused by Wandayuu's meddling schemes. [[HilarityEnsues Hilarity naturally ensues,]] as Eri is besieged by spacefaring freeloaders, bickering aliens, [[{{NakedPeopleAreFunny}} unexpected nudity,]] and at least one [[{{TheResenter}} superhuman rival]] bent on eliminating the competition.

!! Tropes:

* ActionGirl: Eri [[{{ClothesMakeTheSuperman}} powers up]] on several occasions, usually with [[strike:unexpected]] [[strike:catastrophic]] [[{{HilarityEnsues}} the usual consequences]].
* AnimatedAdaptation: 112 episodes broadcast between 1989 and 1991, along with a 40 minute animated movie ''(Chinpui: Eri-sama Katsudō Daishashin,'' aired in 1990). Both were surprisingly faithful to the original manga.
* BadFuture: Inverted to some degree when a [[{{TimeTravel}} time traveling visitor]] informs Eri that she's destined to marry Lulealv within three years. Despite her initial misgivings, it appears that she ''will'' actually fall in love with the Prince at some point.
** Almost inevitably, the time traveler turns out to be [[KidFromTheFuture her own son]], who wanted to meet his mother when she was ''his'' age.
** The family resemblance suggests that Lulealv is not only human, but drop-dead gorgeous to the bargain.
* BarbieDollAnatomy: Averted in the manga, especially when Eri receives a life-sized ''anatomically correct'' "boyfriend doll" from Prince Lulealv (which she promptly returns). The anime version wasn't quite as explicit (though it was pretty damned close all the same).
* BeCarefulWhatYouWishFor Wish Fulfillment. See last three examples for details.
* BlandNameProduct: The [[{{Franchise/Barbie}} PARPY]] doll that is popular with the girls.
* BewareTheNiceOnes:
** Eri when anyone threatens Uchiki-chan.
** Chinpui when anyone threatens Eri. We're talking [[PlanetEater Galactus mode]] here, folks.
* BookDumb: Both Eri and Ooeyama are not too good in studies.
* TheBully: Ooeyama, the series' resident Gian clone. The difference is that, being the main character a girl, he just play pranks like lifting her skirt. He has no problem instead to punch boys like Uchiki.
* ButtMonkey: Eri's long-suffering Father, for some unknown reason. Whenever one of Wandayuu's [[RubeGoldbergDevice Rube Goldberg contraptions]] malfunction, poor old Mr. Kasuga always seems to wind up with egg on his face.
* CanNotSpitItOut: Eri ''really likes'' Uchiki-chan, but just can't quite spit it out. For his part, Uchiki is just too darned thick to notice they're way past the [[JustFriends friendship zone]].
* CoolShades: Majiro, the talking anteater referenced above. Beats the living crap out of Ooeyama after he teases Eri in the street.
* CowardlyLion: Uchiki-chan. Despite his diminutive stature, Uchiki constantly stands up for smaller children being bullied by Ooeyama, (and frequently takes a beating for his trouble).
* DirtyKid: Ooeyama often lifts Eri's skirts.
* DreamingOfThingsToCome: Eri sometimes has dreams where she has married Lulealv and moved to Mal.
* {{Expy}}: Few from ''Anime/{{Doraemon}}'':
** Chimpui of Doraemon.
** Ooeyama of Gian.
** Sunemi is a DistaffCounterpart of Suneo.
* ExtremeDoormat: Eri's sweet-natured father is constantly [[HenpeckedHusband henpecked by his domineering wife]], who rules her domain with an iron fist.
* TheFaceless: Prince Lulealv. Although never actually seen in person, Eri often dreams that he ''literally'' has no face.
* HammerSpace: Chinpui stores an infinite number of reality-warping devices in his ears (Yes, that's right - ''in his ears''). This being a Fujio series, most of his gadgets cause more trouble than they're worth.
* JerkJock: The bully Ooeyama is weak in studies, but best at sports.
* JerkWithAHeartOfGold: Whenever Eri finds herself in a jam, Chinpui agrees to help out ''if'' she promises to marry Prince Lulealv. Eri adamantly refuses, but Chinpui helps her anyway.
* LaserGuidedKarma: Ooeyama when he gets beaten up by various aliens, the most famous being a badass talking anteater with the [[{{CoolShades}} coolest shades]] in the cosmos.
* LoveTriangle: Eri and Sunemi have both a crush for Uchiki.
* NiceGirl: Hotaru. She is sweet and careful girl in Eri-chan's class. She is good in studies and has many friends. She likes Chinpui as a pet and thinks that Wandayuu is a funny dog.
* NoSenseOfPersonalSpace: Alien visitors seem to have no concept of privacy, frequently turning up while Eri is taking a bath (like Shizuka in ''Anime/{{Doraemon}}'').
* PantyShot: The principal form of {{Fanservice}} with Eri (that never wears pants).
** For example, as an [[CuteClumsyGirl exuberant tomboy]], Eri constantly tries jumping the fence on her way home, often landing flat on her face with her skirt over her head.
* RelationshipSabotage: Wandayuu when trying to sabotage Eri's relationship with Uchiki, so she can marry the Prince.
* ReluctantFanserviceGirl: Any photograph taken of Eri will inevitably turn out to be a PantyShot or a nude. This is because both the interstellar paparazzi and the universe in general are determined to embarrass her.
* TheRival: Darusa, a superpowered contender for the throne. Comes to Earth several times, planning to remove Eri from the equation, only to discover that Chinpui has a badass streak of his own.
* RobotBuddy: Chinpui. OK, while he's not technically a robot, he occupies precisely the same role as ''Anime/{{Doraemon}}'', right down to {{Time Travel}}ing excursions to the Jurassic era.
* RubeGoldbergDevice: Many of Wandayuu's grandiose schemes involve ridiculously complicated doo-hickies, all of which [[{{HilarityEnsues}} backfire on the usual suspects]].
* RunningGag: Running gags involve slapstick and domestic comedy, particularly the chaos wrought by Wadayuu's unwelcome visitations.
** Wandayuu always [[BadNewsInAGoodWay announces his arrival by shouting "congratulations!!"]] and showering Eri with confetti and streamers. The resulting mess requires a miniature black hole to remove it.
* SpoiledBrat: Eri's neighbor, Sunemi. An insufferable blowhard, she spends most of her time bragging about her family's wealth. Frequently upstaged by Eri's [[{{GirlNextDoor}} down-to-earth modesty]].
* StrongFamilyResemblance: Eri is very similar to her mother.
* {{Tomboy}}: Eri-chan, without a doubt. In Japanese culture, jumping fences and storming in through the back door is [[{{ValuesDissonance}} considered extremely unnatural]] for [[{{DoubleStandard}} girls of any age]].
** Eri's mother's [[MarsAndVenusGenderContrast despairs that she'll ever find a husband]], as she avoids housework like the plague and can't cook ''anything'' apart from ramen. Fortunately, this happens to be Chinpui's favorite dish.
* TomboyAndGirlyGirl: Eri friends, Sayaka and Hotaru.
* TrademarkFavoriteFood: Chinpui likes to eat ramen. He gains energy from it and uses it for his powers.
* UnwantedSpouse: Eri ''really'' doesn't want to marry the prince. Unfortunately for her, ''everything'', from a glimpse of her future in a crystal ball to a visit from her KidFromTheFuture, seems to indicate that she WILL become the prince's bride one day.
* WeirdnessCensor: Neither of Eri's parents seem to notice the stream of talking animals flowing through the household (although her father is initially [[OhCrap freaked out]] by the "weird blue monkey" in the living room).
** It's also worth noting that Mrs. Kasuga absolutely ''hates'' door-to-door salesman, considering them less human than any of Eri's unearthly visitors.
* WhyDidItHaveToBeSnakes: Chinpui fear anything that even vaguely resembles a cat - even one of Eri's stuffed animals.
