Development Notes

ThornBrain and JigglyJacob began scriptwriting on May 15, 2016. Due to the length of the original movie and their writing style, they expected the script to take multiple months to complete, but it instead took a year due to extended periods without progress. The movie was set for Summer 2016, but Thorn changed his focus to working on How I Caught Your Mother through June, and they did not continue writing for the movie until September 14. Travis wrote a bit with Thorn and Jacob on September 26.

After September, and for no specific reason, TheMidnightFrogs as a whole went into indefinite hiatus. Travis, due to work and his personal life taking up all of his time, formally dropped out of writing with the team as well as TheStrawhatNO! in early 2017. Thorn and Jacob did not return to writing the movie's script until April 5, 2017. Thorn and Jacob completed the script at midnight May 15, 2017, a full year after they began writing. Some recording was completed in the following weeks with Thorn, Jacob, and Jon, but multiple other voice actors were unavailable. By the end of 2017, TheMidnightFrogs had quietly ended, and the movie was shelved with the expectation that it would never be made.

In March 2019, after Yoshi returned to TheStrawhatNO! full-time, Thorn pitched to Jacob the idea of finishing the SFA Movie in-time for the series' 10th anniversary in February 2020. Jacob agreed, and they plus Yoshi gave the script one final, light revision. Thorn resumed recording and directing in August and September before beginning editing in October. Boods was hired to draw the movie logo and original animation frames that same month. All voices were recorded from August through February, with Carrie Johnston and Logan Laidlaw taking over late in production as Momoka and Paul, respectively.

Thorn, Yoshi and Jacob held a livestream on January 5, 2020 on TheMidnightFrogs channel where they watched SFA seasons 1 and 2 to celebrate the channel's 10th anniversary. Thorn ended the stream by airing the long-belated final episode of Ask GiroDoro, which was immediately followed by a secret trailer for the movie, showing the full intro sequence. The movie was then formally announced for February 16, 2020, the series' 10th birthday. Editing was completed on Valentine's Day, with Thorn's Patreon patrons getting early access to the movie, before it finally premiered at 12PM Pacific on the 16th.

  • The intro carries over from the final episodes of Ask GiroDoro, wherein Viper tells Giroro and Dororo about his hidden treasure stashes across Earth. The latest one is in Macchu Picchu, and they've brought the rest of the platoon and Fuyuki to find it.
  • Tamama runs off, half-heartedly saying "G.I. Joe", a callback to SFA5.
  • Giroro tells Keroro "If we die here, I'm gonna kill you", a callback to the similar line "If you don't stop dying, I'm going to kill you" from SFA15.
  • The platoon almost never refer to the Keronian OJ as "orange juice", only "OJ". Giroro noted in the final episode of Ask GiroDoro that they found the bottle in one of Viper's treasure stashes. Its powers of bringing nonliving things to life are used throughout the episode, and Keroro realizes that Viper used the OJ they found to bring Dark Keroro back to life.
  • Dark Keroro externalizes Keroro's narcissism by being openly attracted to him.
  • Keroro constantly hints that he's secretly depressed: he says that he has nothing to live for, that he's had a busy week of crying, and when he thinks he and Fuyuki have found the light at the end of the tunnel that leads to the afterlife, he runs off saying "Full speed ahead, bitches!"
  • Shivava is constantly trying to get anyone around him to notice him and think he's cool. He finally snaps at the end of the movie when Tamama and Momoka ignore him in favor of their own argument.
  • Miruru is using Pururu's health reports on the Keroro Platoon from SFA11 to learn about them. She mistakenly thinks that Keroro is Carl, who was actually the Gundam model Keroro was holding at the end of SFA11.
    • Multiple jokes are made from this that reference the Carl's Jr. fast food chain.
    • The real Carl appears in the latter half of the movie, "Carl" simply being what Keroro calls his Gundam model at the time. Keroro then dubs Dark Keroro "Carl" at the end of the movie in honor of Gundam-Carl's destruction.
  • Miruru and Dark Keroro tracked Viper's message from Ask GiroDoro episode 18 to find Earth.
  • After Dark Keroro does his "god" monologue, Shivava refers to him as "God" or similar for the rest of the movie.
  • Momoka has tried to get over Fuyuki after the SFA25 roll call by cloning him a minimum of 23 times.
  • Koyuki no longer has a house after Paul destroyed it in the SFA25 roll call.
  • Giroro briefly thinks that Doruru is his father before saying "Oh, no, it's not, thank god", a joke about how so many characters were rewritten to be related throughout SFA.
  • Keroro describes Doruru and Shivava as "shittier Garuru" and "shittier Putata", which doubles as a joke about the similarity of many character voices (Shivava was originally going to be voiced by Thorn and would have sounded very similar to Putata).
  • Shivava sings "Your Love", the movie's theme song, while not paying attention.
  • Keroro tells Tamama to "breathe with your lungs, damnit!", a callback to Tamama saying she doesn't breathe out of her mouth in SFA25.
  • Dark Keroro readies to attack by saying "Five o'clock!", a callback to Keroro doing the same thing to Giroro in the post-credits of SFA16.
  • Keroro says he has 36 (4 times 9) broken bones.
  • Keroro once again tries to sell some coupons.
  • Fuyuki knocks a naked Raiden bird out of the sky.
  • Like his "Giant Ninja Fuck-You Star", Dororo calls his small saucer a "Tiny Ninja Catch-You Star".
  • The Violent Beauty Pageant has been clearly rigged in Koyuki's favor: Natsumi's axe is a squeaky toy, and the pre-recorded audience boos her. Dororo outright says "Natsumi's gonna die."
  • The Violent Beauty Pageant awakens a bloodlust in Fuyuki, as he repeatedly attempts to kill or eat the others through to the river cave scene.
  • Dororo tries to get Koyuki to snap out of her mind control by saying he's lost in the city and needs a tracker.
  • Fuyuki sends everyone through a trapdoor by saying "I'm sorry Sarge, the base ate me", a callback to Mois saying "I'm sorry Uncle, the base ate him" in SFA17.
  • Koyuki offers to trade Dororo's knife for a Band-Aid, but he declines by saying "You'd probably catch something else, Pal", a callback to him being a carrier for every disease ever.
  • Mois tries to make Tamama feel better but only makes it worse by bringing up both of her and Keroro's babies who ran off (Kilili and Kemama.
  • Giroro yells out "BLRFLHAGEN" when he gets hit by the pink gas, which is the same enunciated noise he makes when hit by snowballs at the start of SFA25.
  • When Fuyuki is knocked out and illuminated by a spotlight, he mumbles "I'm just an old TV..."
  • Dark Keroro repeatedly gets Fuyuki's name wrong, calling him "Fuyoukeh", "Yogi" and "Funky".
  • Fuyuki already thinks that Dark Keroro is out to kill Keroro, like all the major villains before. He suggests kidnapping Natsumi instead, a call-forward to the second SFA movie, which will likely be of the second Keroro Gunsou movie wherein Natsumi gets kidnapped.
  • When Carl comes to life, he proclaims "I am no longer penis", a callback to Keroro saying "This is Carl. He is penis" in SFA11.
  • Kululu is posting to "", saying "Keroro's appendix is lopsided, and he should feel bad about it".
  • Darkerobobo appears with "Who wants to play Evil Ball?", a callback to Giant Robobo in SFA22 appearing with "Who's ready for some football?"
  • Keroro yells "FRIENDSHIP!", a loose callback to SFA4.
  • Tamama calls out to "Jeezy B" for help despite them "breaking up", a callback to Beetle Jesus and their subsequent union that led to Kemama.
  • Momoka calls back to Keroro Love Fighters with Momoka Love Fighters.
  • Keroro mentions Weight Watchers again after Tamama did in SFA25.
  • Momoka addresses how she's been absent for many years, referring to her lack of appearances in the whole of SFA. This is further driven home by Koyuki and Mois having no idea who she is.
  • Natsumi calls back to the many times the Hinata house or its roof was destroyed and clarifies that Kululu is the one who rebuilds it every time.
  • Fuyuki callsback to the many people they've fought who either forgave Keroro or died.
  • Keroro follows it up by saying "My platoon's changed the past, but we've learned you can't change the past."
  • Momoka and Tamama finally air their grievances after Momoka attacked Tamama ("You tied me to a tree, you freak!") and Tamama took advantage of Momoka's death by living in her mansion until Momoka was resurrected.
  • Giroro's oft-noted incompetence with guns is finally resolved as he beats Doruru: "Huh. I guess knives are my thing." Doubles as a subtle joke about his and Dororo's surprising relationship.
  • Saburo's silence is given an additional joke in the credits: his section has no vocals, and after several seconds of silence, Natsumi turns to him in confusion.

Other Jokes and References

  • Viper's base has Patrick Warburton saying "Uhh" as an alarm. The audio is taken from a showcase of Warburton's voice acting, and as a joke he is credited as being voiced by "Skidmark Salieri". The joke is a leftover from early in scriptwriting where Fuyuki thinks Macchu Picchu is a theme park Viper constructed based on The Emperor's New Groove.
  • Giroro remarks that Viper's base reminds him of when he went to the dentist, a reference to Dororo's dentist father in the original Keroro Gunsou who was replaced with Viper in SFA.
  • Twice in the movie, characters call something pink and are angrily corrected with "Lavender!", a reference to an old call TheMidnightFrogs held on Skype with some fans where Jacob found a fanart picture of Pururu with sakura petals. Thorn joked that they connect because "she's pink and she's dying", but it was later noted by viewers that Pururu's actually lavender.
  • Miruru calls Dark Keroro "Grand Cardinal", which is based on an unused Joriri joke where Lil' Keroro calls him "Grand Cardinal of the Coocoo Clock".
  • When Giroro gets knocked out, he says "potatoes" like Eduardo from Foster's Home for Imaginary Friends.
  • Shivava calls Dark Keroro "God...Boss...Bruce...Clapton...", a reference to Bruce Springsteen's nickname of "The Boss" and Eric Clapton's nickname of "God".
  • Doruru's name for Natsumi in the Violent Beauty Pageant is "Jon Anderson", the name of the original vocalist for Yes.
  • When Natsumi snaps out of her mind control, she thinks she's in the Thunderdome, a reference to the third Mad Max movie.
  • Shivava quotes the original Metal Gear Solid when everyone disappears into a trapdoor. Old Snake from MGS4 appears to say "Fox DIE" and blow him up.
  • While Dark Keroro monologues to himself, Miruru sadly watches a clip from an old Spider-Man cartoon of Mary Jane dancing goofily in a cage to silly music.
  • Mois mentions that she has a sister, a reference to Angol Fear from the original Keroro manga.
  • When Nazca reveals that she's also Miruru, Fuyuki says "That almost got really weird", a joke about the myriad of potential love interests he has in the original show.
  • Tamama yodels like the Yodeling Pickle.
  • The advertisement that gives Kululu his drones is a reference to the "Congratulations, you've won!" pop-up ad from the older days of the internet.
  • Kerobobo casually loses his arm while walking over to Dark Keroro, a joke about the fight that was cut out from that scene wherein he loses the arm.
  • Mois says Keroro "fell to Earth like Ichabod", a reference to Ichabod Crane from Sleepy Hollow.
