Natsumi: Alright, let's get this over with. Who and what are you? Keroro: Uh, I'm Keroro. I'm the house inspector. Good house. Fuyuki: You look more like a house maid. Natsumi: Don't engage it in conversation! Fuyuki: It's a talking frog! Keroro: That's "Mister Sexy" to you! Oh...
Aborted Arc: Giroro's crush on Natsumi. Its last appearance was in Episode 10 before Giroro turned his affections toward Dororo, though this was foreshadowed a few times. The sudden drop finally gets addressed in Episode 18: the emotional stress of courting Natsumi to no avail made Giroro lose interest. Presumably he turned his attention to Dororo shortly after.
Giroro: "You know what? Forget it. I like cock now."
Abridged Series: Not the first abridging of Sgt. Frog, but by far the most successful. It became one of the few abridged series to have a conclusive ending on November 2012. For a time.
All There in the Script: Aki's husband stuck in the Hinatas' basement, who was eventually confirmed to be Todd Sirkowski, was originally written in the SFA2 script as "Haru", the Fan Nickname for the unseen Hinata patriarch in Sgt. Frog.
Alternate Continuity: The in-universe explanation for SFA1R, SFA2R and SFA3R is that they are how the timeline was going to be before Future Kululu began time-hopping. Out-of-universe, the writers just didn't like them.
American Accents: Pururu is given a Brooklyn accent. It's actually voice actor LillyLivers' natural accent.
Angrish: Tamama's incoherent babbling to Giroro in Episode 8.
Arc Welding/Continuity Creep: The series started with the intent of being as Negative Continuity as the original. Then Episode 10 arrived and, alongside a heaping helping of retcon, developed its own plots and subplots. As creator Yoshi put it:
Artifact Title: Defied with SFA: Reset. Reset was originally going to be the title of a second SFA series, but the title would have lost its meaning right after the first episode, so it was simply shortened to a special as a lead-in to SFA Season 3.
Keroro (and occasionally other characters) have random bouts of Spanish. While Funimation did this with Angol Mois just for laughs, The Midnight Frogs did it because project leader Yoshi is actually Dominican.
Fun with Subtitles often happens at the same time, especially in cases where the supposed Spanish is actually gibberish, or is an actual Spanish statement being passed off as gibberish. Episode 1 also featured Spanglish interplay between Keroro and the caption.
Keroro: "Soy un major yes." Caption: I am grande si.
Future Kululu's random placement of the numerals 4 and 9 become hints when the Japanese language is involved.
Keroro uses Morse code in Episode 12 to send a message to Giroro. It's assumed that he's sending the Serious joke he is saying at the same time; he's actually tapping out Dororo's catchphrase, "I'm lonely".
With the remake of Episode 1, Kululu's brief appearance at the beginning turns into one when the viewer reaches Episode 10.
In Episode 2, Fuyuki thanks Keroro after singing a song, though Keroro can't hear him. In the Post-Credits, Keroro suddenly says "No problem, Fuyuki!" and has no idea why he said it.
The Episode 8 Post-Credits includes a voice saying "Dang, man! Mop need him a cigarette!" The end of Episode 10 features a mop coming out of nowhere and saying "And I'm a talkin' mop!"
The Narrator also leaves early-on in Episode 10 to get some dollar store cheese. Future Kululu's base turns to be a dollar store. Also, the credits feature Mop screaming "Cleaning up the cheese! CLEANING UP THE-"
One of Tamama's invasion plans in Episode 9 is putting cake into the Hinata house's fridge. Later, Kululu finds cake in Keroro's fridge.
Everyone goes on a picnic in Episode 10, with Dororo insisting on holding hands. Later, Giroro seems to freak out after reading Keroro's letter to them, with Dororo saying "See? this wouldn't have happened if you held my hand."
In Episode 6, Dororo temporarily loses his sight and wonders if it has something to do with the coffee. In The Stinger for Episode 12, HQ tells someone to "fix the coffee machine; I think it's making me blind".
Episode 13 has Keroro remarking the object delivered from HQ was not what he wanted for his birthday, first referenced in Episode 6.
Two with Natsumi's power armor and its built-in message machine:
Natsumi listens to a few of the recordings in SFA17, and Episode 18 opens with her listening to message 297.
Message 299 has Giroro angrily storm out of the room he's recording the messages in. After Natsumi activates the power armor and flies off, Giroro returns to finally end the recording. Cue message 300.
Canon Discontinuity/Retcon: The original first three episodes were remade in the interim between Seasons 1 and 2, with the originals being renamed 1R, 2R and 3R, the "R" meaning Retconned. Episodes 1 and 2 were remade simply to make them better and more in-line with the now-developed writing style and quality, and Episode 3 was remade to fix some plotholes that resulted from the first two remakes.
Giroro and Dororo become closer friends at the end of Episode 7. By Episode 11 it's much more noticeable in how the two back each other up at different points in the episode, and in the Episode 14 Post-Credits Dororo asks Giroro to marry him in a very idiosyncratic way.
After having an episode-long daydream in Episode 9, Tamama decides that she is happy being the submissive one in her relationship with Keroro. This doesn't stop her from laying out everything that annoys her about Keroro right to his face in Episode 12.
Keroro's selfishness and poor treatment of his friends causes Fuyuki to break down emotionally and lay out "The Reason You Suck" Speech. Though Keroro doesn't immediately act any different, he seems to respect Fuyuki more the following day.
Keroro's personality didn't truly develop until around Episode 3, with Episodes 1R and 2R having him simply be a weak parody of the original.
Kululu's personality also mellowed out considerably after the first season, becoming more apathetic than Jerkassy.
This was the personality the team originally intended for him, but when Jpace92 became his VA they went the creepy jerk route. Then Future Kululu happened, and they steadily went back to making him apathetic.
The constant appearance of the numerals 4 and 9 ("What is this code?!"), his bizarre demeanor through the second half of Season 1, him suddenly disappearing from Tamama's office in Episode 9, and his ethereal cackling throughout Episode 10 all culminate in Future Kululu's reveal in the climax of Episode 10.
Tamama, upon Keroro introducing him, calls himself "a pretty princess" in Episode 2. Then in Episode 8, Giroro reads a joke from Jimmy Carr about vaginal pain, during which Tamama can be heard groaning "ow". Tamama also remarks about having "air boobs" in Episode 9, then later discovers a "hole" in the Post-Credits. The end of Episode 10 is Tamama revealing that "he" is actually a "she", with her attempting and failing to do so throughout the episode.
Cloud Cuckoolander: Every character is "off" to some extent. Fuyuki, Tamama and Aki straddle the line between this and The Ditz, and Dororo straddles the line between this and serious mental illness. Even the Straight Man/Only Sane Man characters of Giroro and Natsumi have their weird moments.
Continuity Nod: Jokes and quotes often reappear in later episodes, usually in an altered form. Proper Running Gags are listed further down the page.
Lil' Keroro describes something as "shooty Deus ex Machina" in Episode 7, which was previously used as "shitty Deus ex Machina" in Episode 4, notably the previous flashback episode.
In Episode 4, Dororo asks Koyuki if Earth ever stops having a full moon, which she flatly responds "no". In Episode 9, Dororo asks the platoon if any of them can actually read; Kululu flatly responds "no".
Dororo seems to briefly lose his sight in Episode 6. When it is discovered in Episode 11 that he has every disease ever, Pururu asks if he can even see. He responds, "Usually".
Giroro mentions (and shows) that flashbacks make him nauseous. Come Episode 11 he is around for both flashbacks, and he promptly reminds us of his little weakness.
As Keroro begins the How We Got Here flashback in Reset, Giroro proudly proclaims that he's "conquered it", 'it' being the nausea.
Keroro took Mois to a "dollar store" when she was a child; Future Kululu's base is a dollar store.
Pururu finds Tamama inexplicably tied to a tree in Episode 11. In Episode 12 the platoon ties Kululu to the ceiling; Pururu remarks to Keroro, "I think your platoon is addicted to rope..."
George Albert Nishizawa's first appearance is him acknowledging Todd's Toilets' hot air balloons from Episode 1 and the George Albert radio commercial in Episode 6.
Internal Homage: Keroro begins an invasion plan in Episode 3 with "We're gonna take a can of soda..." In Episode 13 while at a Halloween festival, he repeats that exact line to the others before the camera cuts away.
In Episode 2 Fuyuki laments that girls aren't attracted to him with "What happened to my game...?" In Episode 13 Alisa kidnaps him, causing him to triumphantly shout "I got my game back!"
Episode 14 has several nods to Episode 4, due in part to it being a flashback to the events leading up to 4.
In Episode 15, a delirious Keroro remarks to Fuyuki "I'm your uncle, and I heard what you said", a Call Back to Fuyuki lamenting about not having an uncle in Episode 5.
Also in Episode 15, Keroro tells Giroro that his brother is coming to Earth, but "bad news, he won't make it to Christmas." In Episode 17, Garuru sends a message to the platoon, "Sorry I missed Christmas."
In another Continuity Cavalcade moment, Keroro drops the sudden revelation that he was sold as a child; he is hinted heavily to be the little brother Dororo said he sold for cash in Episode 8. Apparently the cash was spent on Viper's bail in Episode 7.
Kululu sings a "HEGH" harmony at the United Nations in Episode 12. He briefly does the same thing in Episode 18 before singing a Pre-Ass Kicking version of the birthday song to Tororo.
The Todd's Toilets balloon from Episode 1 reappears in Episodes 17 and 18.
Credits Gag: Every credits sequence includes a message at the very end after the ownership disclaimer, usually a follow-up to a joke, a thank you to cast members, or just a something general from the creators to the viewers. Season 2 also lists Let's Player MrFailGame in the credits as a figure or object that either does not speak or does not even appear to begin with.
Averted for most of the characters, though Tamama is a weird example. He starts out being an aversion, unlike both the Japanese and Funimation versions of the original series, but he is revealed to be a girl in Episode 10, becoming both a subverted/straight example and a complete inversion of the original's crossdressing voice.
Giroro also "attempts" this himself by pretending to be Sumomo.
Young male character Private Taruru is voiced by female VA LillyLivers.
Cross Over: Fuyuki appeared briefly in both of TheMidnightFrogs' Pokemon one-shots, and Birdy from Thorn's Jetters Abridged interviewed the platoon in Episode 9 and left a message about Jetters Abridged in the Post-Credits for Episode 13.
Debut Queue: The first five episodes introduce a handful of the main cast at a time: Keroro and the Hinatas in Episode 1, Tamama and Momoka in Episode 2, Giroro and Kululu in Episode 3, Dororo and Koyuki in Episode 4, and Mois in Episode 5.
Deconstruction: Fuyuki's monologue in Episode 18 is this for the entire series. Watching Keroro be a Jerk Ass to his friends may be funny, but the scene reveals just what effect this has on everyone around him, and it's not pleasant.
Deliberately Cute Child: Both Mois and Koyuki have played up their cuteness to get the attention of their respective love interests.
Demoted to Extra: Mois, due to her voice actor often being busy, and the writers getting anything they could have really gotten out of the character in her first episode. She still has the occasional line, and the season finale features her more prominently, but overall the writers just never have a use for her.
Dororo was mentally, emotionally, and often physically abused by Keroro and Giroro throughout his life, developing an obsession over them and becoming generally unstable. After he and Giroro began connecting, Dororo was finally able to break from his obsessions and issues to settle into a happy relationship.
Episode 18 pre-Reset: After constant threats of death, intense fights with the Garuru Platoon, and friendships being tested and strained, the Keroro Platoon actually take over the world, and nothing can threaten their safety anymore.
Bittersweet Ending: Only because everyone on Earth is time-locked, and everyone else in the universe is dead, including any friends and family they might have had on Keron. However this aspect of the ending was undone in SFA: Reset, so now it's a fully happy ending. Except people want to kill Keroro again.
Zoruru is the clear evil counterpart to Dororo: where Dororo is friendly and always feels alone regardless of if people are with him, Zoruru is a cold-blooded assassin who is always alone but feels like people can never leave him alone.
The rest of the Garuru Platoon are subversions. Garuru is out to invade Earth just like Keroro's initial mission, but he is so warm and friendly that, if Giroro were still in the Keronian military, Garuru would be the good counterpart by comparison. Taruru isn't much of a threat, and he's at least as clueless as Tamama. And Kululu's counterpart Tororo, despite possibly being dangerous, is really just unhinged over his father more than anything.
Dororo blames his massive friendship and emotional issues on his parents.
Keroro also blames his parents for setting the stage for everything to go wrong in his life.
Follow the Leader: The series inspired at least two other (now defunct) Sgt. Frog abridged series, according to those series' creators: Bokegaeru Productions' Sgt Frog: The Other Abridged Series and AbridgeShion's Keroro Abridged.
Knight of Cerebus: Subverted with the Garuru Platoon. Garuru's deep, dramatic, threatening voice; Zoruru's nightmarish attitude; and the platoon being the first genuine threat ever certainly take the show into darker territories than before. However, Garuru clearly does not take himself seriously, Zoruru is too messed up to be effectively scary all the time, and Taruru and Tororo are essentially useless.
Large Ham: Keroro, Kululu, Garuru, and the occasional bit character, all to varying degrees.
Viper is Dororo's father. Or is it the blue frog in Dororo's meditation DVD? It's probably both.
Keroro is Dororo's little brother that was sold for cash as a child, thus making him Viper's son as well. Naturally, Keroro is too dumb to put the pieces together. Dororo has to tell him upfront in Ask GiroDoro SFA.
Major Injury Underreaction: After Keroro slams his fist against a solid stone wall, his only reaction is calmly stating "Huh... I just broke my hand."
Man, I Feel Like a Woman : Subversion. Tamama was probably always a girl, but she only realizes this upon discovering her vagina.
Myth Arc: It doesn't get revealed until the end of the first season, but the overarching plot of the series, and the reason the platoon are on Earth in the first place, is that Keroro is useless and people want to kill him for it.
Never My Fault: The gist of Keroro's monologue in Episode 18. It's what finally breaks it to Fuyuki that Keroro is not the friend he thought Keroro was.
Nightmare Retardant: Invoked in Episode 10. While the Nightmare Fuel level of Future Kululu's scene is debatable, the sudden appearance of REM's "Shiny Happy People" video in the background is a signal to the viewer that things are going to get stupid.
No Bisexuals: Averted overall; deconstructed in Episode 11. Keroro always acted as a Straight Gay while having a very obvious attraction to women, yet when Tamama reveals that she is really a girl, Keroro exhibits a form of "straight panic" and fails to acknowledge that he may simply be Bi. The ending of the episode parodies the LGBT mantra "It's okay to be gay" by saying "it's okay to likebothmen and women". Giroro, the off-screen Wholesome Crossdresser, had this figured out from the start and gets irritated at Keroro's blatant ignorance.
Out-of-Character Moment: Kululu consciously drops his creepy demeanor to bring Tamama back to reality in Episode 9. He only did this because Tamama was being particularly out-of-character himself. Justified in that the whole thing was Tamama imagining if he were dominant in his relationship; he very much is not, and it got very out of hand for everyone.
Kululu works his way up the Nishizawa Corporation, nearly making it the leading world economic power in the process. Soon he finds himself addressing the leaders of the world, whereupon he...sings a "HEGH" harmony. He's back with the platoon the next day.
Saburo is played as mute, or at least he never gets the chance to speak. Let's Player MrFailGame is listed in every Season 2 episode as a person or object that never speaks. When Saburo finally gets a line in Episode 18, it's voiced (for real) by MrFailGame.
A variation in Episode 7. While the characters cuss profusely as adults, their young selves avoid cursing throughout the episode until Zeroro meets Solid Snake and screams out the F Strike in terror, whereupon Keroro and Giroro immediately hit puberty and begin cussing.
Fuyuki drops one while tearfully berating Keroro for his selfishness and poor treatment of his friends.
The series overall is a subversion in stark contrast to the original series. Yoshi and Thorn subscribe to the idea that if you can come up with your own joke, it'll be funnier than making a reference. (Not that they don't make references, but they're few and far between, especially when compared to the original series.)
Solid Snake is a straight example. Practically every one of his lines is a quote from Metal Gear Solid 1 and 2.
Revisiting The Roots: Downplayed example. Thorn felt that Episodes 8 and 9 were too self-aware, stilted and lacking in ideas. He and Yoshi then wrote Episode 10 with the intention of returning to the more relaxed and ridiculous writing of the mid-season. The first half of it, anyway.
Revolving Door Casting: Momoka in Season 1, who went through five different voice actors before she was finally killed off the following season.
The numerals 4 and 9 appear frequently in random places and dialogue. Revealed to be a message from Future Kululu that he is going to kill Keroro. The numbers continue appearing after Future Kululu returns to his time. They are also apparently the price Keroro was sold for as a child: $49.99.
The Ask GiroDoro SFA audio blog. Initially conceived as a Spin-Off before Thorn decided to end SFA, after which the blog continued the story. It also became a Prequel to SFA Season 3 via the Sgt Frog Abridged: Reset special.
Reporter: "We are live at Generic Japanese Bridge, where a live seal-"
Person off-screen: "No, it's a Pikac!!!"
Keroro's line "Huh. I just broke my hand" in Episode 9 is a Shout-Out to Koyuki-voice actor Revy Moonshine's Patlabor the Abridged Files Movie.
Future Kululu's pencil mustache was inspired by Ron Mael's signature mustache since the 80s.
While Solid Snake provides plenty of Metal Gear references on his own, the message left by HQ in the Post-Credits of Episode 10 is a Shout-Out to similar sequences at the end of Metal Gear Solid credits.
"Pretty Girl's All Mine" - Parody of Chris Isaak's "Pretty Girls Don't Cry". Sung and performed by Thorn from the perspective of Giroro, singing about his crush on Natsumi.
"The Lonely Dance" - Parody of Men Without Hats' "Safety Dance". Sung by ThornBrain as Dororo with RevyMoonshine making vocal cameos as Koyuki. Dororo tries to pretend that he doesn't need his former friends, only for him to have catastrophic emotional breakdowns in each chorus.
"White Blanket" - Parody of "White Christmas", sung by Dororo about wanting a security blanket due to being lonely during the Christmas season.
"Giroro's in Natsumi's Room" - Parody of "Santa Claus is Coming to Town", sung completely out-of-time by Keroro and with incoherent lyrics.
"Walking in a Mall at 12 O'clock" - Parody of "Walking in a Winter Wonderland", sung by Fuyuki about dangerous Black Friday shopping.
"I'll be Home for Christmas" - Sung by Dororo about how nobody ever notices him, not even in his dreams.
"Baby, It's Cold Outside" - Sung by Natsumi and Giroro, with Natsumi trying to get Giroro to leave her room.
"Durdeedeedur" - Also a parody of "Santa Claus is Coming to Town", sung by both Yoshi's and Thorn's respective Tamama's, with even more incomprehensible lyrics than Keroro's version.
"Carol of the Kululu" - Parody of "Carol of the Bells", sung by Keroro, Tamama, Dororo, and Giroro about Kululu and how he acts. It is the only song that does not utilize a karaoke track.
"The Valentine's Parody" - Parody of Billy Joel's "The Longest Time". Sung by Yoshi as Keroro with Thorn singing cheap backup as Giroro and Dororo. Keroro sings a Valentine's song for Tamama, alternating between being a romantic, a cheap date, and a general Jerk Ass.
The team also recorded a parody of The Beatles' "Yellow Submarine" way back in December 2009 called "Tamama's Titties". It was based on an in-joke involving Tamama with breasts, and though Thorn still has the file, it is not available to the public. It and the in-joke it was based on, however, did influence the direction the team would take with Keroro and Tamama's relationship.
So Proud of You: Garuru to his little brother Giroro, but for mundane things like when he taught Giroro how to read. It drives Giroro nuts.
Natsumi: "You know, he seems like a pretty nice guy." Giroro: "But he's so supportive!!!"
In Episode 8 - instead of the usual "woosh" that would be used in such a situation - Kululu slides into frame with a rubbery stretching sound.
Tamama makes a similar sound when turning to face Taruru in Episode 17.
Spell My Name with an S: The series goes with the "Kululu" spelling and pronunciation of said character's name. They also usually emphasize the second syllable in Giroro's name, and they spell the "Sgt" in the series' title without a period.
The Stinger: Every episode features two brief clips after the credits (referred to as Post-Credits), usually following up a joke or situation earlier in the episode, or filling up a plothole. They also served as Sequel Hooks from Season 2 on.
Yoshi's Keroro voice started out as him trying and failing to emulate Todd Haberkorn and instead just talking like himself. Circa Episode 5 his Keroro voice no longer has Haberkorn influence and is now him...just talking like himself.
Jpace92's Kululu gradually became rougher and more sinister after his first appearance. Even his casual lines sound disdainful now.
