History YMMV / SgtFrog

** The Space Octopus scene with Momoka in Episode 6. The [[GagDub English Dub]] makes it worse by having the narrator get grossed out and off-handedly mention an octopus egg implanted in her stomach. Thankfully, that's a story that never comes to pass.

** The part in one of the earlier episodes where a half-drowned Momoka gets... CPR'd/molested just off-screen by a tentacle monster alien while the others look on with horrified looks on their faces -- and then they all agree not to ever tell her that it had happened. The dub takes this to the next level, stating that the "Life-o-puss" laid an egg in Momoka's stomach. When the creature zooms by in the scene after the eyecatch, Momoka asks if it planted something in her, which Fuyuki denies.

* CrossesTheLineTwice: As seen in the 1st Season's 25th Episode, Keroro will '''not''' hesitate to blow up Earth [[EvilIsPetty if one damages his hard work (mostly his plastic model kits)]].

%%* CreatorsPet: Joriri. ''He just keeps showing up!'' %%How is he disliked?

** Some of gory violence can be hard to stomach, especially in the original manga. Natsumi has even done acts to Keroro such as: whipping him several times, crucify and burn him, attempt to punish him via the extremely gruel "ishidaki", and even outright tear him in half!

* DesignatedHero: While the Keronians do cause a lot trouble, Natsumi's beatings of are extremely brutal, bordering onto horrific. Likewise, she will severely punish Keroro over things that aren't even his fault.

* JerkassWoobie: Keroro. He may cause trouble, but a lot of the harsh retributions he receives can make him UnintentionallySympathetic. There are also many times when he is brutally abused for no good reason, with almost no one trying to protect him or call out the abusers. It becomes worse in newer stories, since he learns to act more considerate and nice towards others.

** Viper. The first Viper is treated by the Keroro Platoon as a deadly serious threat, who easily captures one and brings the rest to their knees. From that point on, despite each successive Viper tending to upgrade in some way, they became a steadily decreasing threat, to the extent entire armies of them weren't more of a menace than any other of the platoon's humorous daily misadventures.

* DesignatedHero: While the Keronians do cause a lot trouble, Natsumi's beatings of are quite brutal, bordering onto horrific. Likewise, she will punish Keroro over things that aren't even his fault.

* {{Fanon}}: The fan theory that the Hinata family's DisappearedDad is named 'Haru' (or any name similar, like Haruki) in line with the family's TemporalThemeNaming[[note]]'''Natsu'''mi = Summer, '''Fuyu'''ki = Winter, '''Aki''' = Autumn, hence Spring = Haru[[/note]] is particularly popular.

* JerkassWoobie: Keroro. He may cause trouble, but a lot of the harsh retributions he receives can make him UnintentionallySympathetic. It's even worse when he hasn't done anything wrong, and yet is still brutally abused by others.

** Purists tend to be incredibly vocal about Funimation's dub of the anime here, although in the minority, but even in its original form the anime attracts a lot of scorn from fans of the Manga. Common complaints are that the show was sanitized for younger viewers, reworked into a marketing gimmick, and the [[BadAssDecay changing of Dororo]] from a TechnicalPacifist who routinely stood up to his friends when they tried doing something wrong into a whiny ButtMonkey who barely even interacts with them.

* ValuesDissonance: This is one reason why the anime ultimately failed to become a hit in North America, despite ADV Films and Funimation's attempts to promote it. While the anime is TamerAndChaster and generally more family-friendly than the original manga, it still has some moments of fanservice that Americans would consider to be too risque for a kid's show, and the RunningGag of Dororo contemplating suicide whenever he's depressed would also be viewed as rather shocking.

* WhatDoYouMeanItsForKids: The manga is [[ShonenDemographic shonen]], but it has a very raunchy sense of humor and the female characters are often a source of {{Fanservice}}. The anime is TamerAndChaster as a result of being made more family-friendly, but there's still some mild fanservice left in as a ParentalBonus, and Dororo frequently contemplates suicide as a RunningGag.

* GermansLoveDavidHasselhoff: The show notoriously failed at being a hit in the United States, but it would be an understatement to say it succeeded in Spain, as it became almost as popular there as it was in Japan. The reasons were a quite good dub, a ''very'' clever adaptation of the original language puns, and an excellent marketing job, all of which caused a success in the country which was compared to that of the legendary ''Manga/BoboboboBobobo''. It even became a GatewaySeries to anime and manga for many Spaniards, as its release coincided with the expansion of internet otaku culture in the country, fitting the frequently parodic/referential humor of the series (which also helped to introduce many famous anime series that hadn't reached Spain, as well as re-introduce some which did but were less known to younger viewers).

* ValuesDissonance: Regarding the Funimation dub. Many Westerners find Dororo's suicidal contemplation tendencies to be rather shocking for a kid's show from Japan.

** Giroro was billed as the galaxy's most dangerous frog in his introduction, but his transformation into yet another ButtMonkey for the platoon impeded any badassery. He still has some moments of competence and is not afraid to terminate with extreme prejudice when irritated (fortunately Keronians are MadeOfIron), but he only sporadically gets any serious fights where he wins. This is a show where ''all'' male characters are inherently far weaker than their female counterparts, after all.

** Keroro in Tamama's eyes who laments that the legendary Gunsou san he's heard in stories is just a silly man child. Of course in that particular episode/chapter (episode 336 and chapter 140) the readers [[spoiler: and Zoruru]] see a glimpse of [[{{CrouchingMoronHiddenBadass}} Keroro we've never seen before]].

** Natsumi Hinata. She is either a [[{{Jerkass}} conscending bitch]] or a well-developed {{Tsundere}}, especially with her moments with Giroro.

* DesignatedHero: While the Keronians are [[HarmlessVillain not really saints themselves]] and Natsumi's beatings of Keroro are mostly justified, sometimes, she even beats the crap out of him even when he's [[UnwantedAssistance trying to help]].

* ValuesDissonance: Many Westerners find Dororo's suicidal contemplation tendencies to be rather shocking for a kid's show from Japan.

* UnpopularPopularCharacter: [[SpellMyNameWithAnS Kururu/Kululu]]. In universe, he is the least popular among the platoon (not counting Dororo who everyone just forgets) with his toy selling worst out of them all. In real life ([[GermansLoveDavidHasselhoff mostly in America]] thanks to the dub), he is frequently at the top of peoples favorite character list, usually in front of or behind Giroro.
