History Trivia / Splatoon2

** The ''Splatoon 2'' artbook shows original drafts of Callie's plotline, including her being NotBrainwashed and morosely living among the Octarians, with her getting her own mech and the final boss fight including backup dancers and a different Octobot King mech.

* IKnewIt:
** After the [[https://youtu.be/869_lwZfyTo Hero Mode trailer]] dropped, many people have predicted that [[spoiler:Callie was brainwashed by DJ Octavio]]. Many people also expected that [[spoiler:the final boss theme is a DarkReprise version of "Bomb Rush Blush" (Callie's solo song), and that Marie would pull an IKnowYoureInThereSomewhereFight via a sad version of "Tide Goes Out" (her own solo song)]].
** Soon after the game released, pointers were discovered in the data for "[=OctGirl=]" and "[=OctBoy=]" as options for character customization, but with nothing associated with them, leading to the "playable Octoling" rumors from the first game to resurface. An early balance patch added more fuel to the fire, with dataminers discovering character attributes for the player's species in addition to the regular customization options, like gender, skin tone, and hairstyle, alongside unused model meshes that looked suspiciously like hair models for both genders of octos, separate from what the [=NPCs=] use. Playable Octolings would be added to the game with ''Octo Expansion'' DLC campaign, released a year after the game's launch.
** After the announcement of the Octo Expansion and the fact that it's located in a subway, many keen eyed fans noted the inaccessible subway entrance in the main plaza, down an otherwise dead-end path. While one could argue the path was merely there for symmetry with the entrance to Salmon Run, these fans speculated it would be the entrance to the Expansion's content and had been hiding in plain sight since day one. Even the sprite artwork of a Gunion (an octopus-like enemy from ''VideoGame/SuperMarioLand'') seen in the subway entrance made it more obvious. They were correct.
** For the Final Fest, many players speculated that "Fly Octo Fly ~ Ebb & Flow", the FinalBoss music from ''Octo Expansion'', would be used as Turf War music. This was confirmed on the last day of the Splatfest, where it played for all matches.
** Just like in the first game, fans predicted that the results of the Final Fest would affect the plot of the next game. In ''Splatoon 3'', the Inklings/Octolings descend into "the wake of chaos" in a new territory.

** The game's final Splatfest, "Chaos vs. Order", took place from July 18 to July 21, 2019, the weekend of the game's second anniversary.

* MeaningfulReleaseDate: In Japan, a special addition of Splatoon 2 with the Octo Expansion built right in was released on '''Octo'''ber '''8'''.

* NamesTheSame:
** Marina isn't the first [[VideoGame/AnimalCrossing Octopus girl from a Nintendo game]]. In fact, she also shares her name with the Italian version of Marie.
** [[http://twitter.com/SwervinMervin98/status/883029066772860928 As someone on Twitter pointed out]], Pearl and Marina have the same names as [[WesternAnimation/SpongeBobSquarePants a certain whale]] and one of her friends.
** The Bloblobber is also an [[http://www.sjgames.com/bloblobber/ action card game]] by Creator/SteveJacksonGames.
** Bisk shares his name with another crustacean-themed character from ''[[WesternAnimation/TransformersRobotsInDisguise2015 Robots in Disguise]]'', although the latter Bisk is actually a lobster. Funnily enough, the Autobots vs. Decepticons Splatfest from the first game in the series used artwork and backstory from ''[=RID15=]'', though Bisk wouldn't appear on the show until a year later... which was still a year before ''this'' Bisk.

* KillerApp: Just like its [[VideoGame/{{Splatoon}} Wii U predecessor]], ''Splatoon 2'' quickly became this in Japan, [[https://gonintendo.com/stories/286105-japan-splatoon-2-sells-over-670k-copies-in-its-first-3-days selling over a third of the first game's lifetime sales]] during its first weekend. Just a month after release, the game managed to sell [[http://www.japanesenintendo.com/post/164536708654 over a million units in Japan alone]]. It would [[https://nintendosoup.com/splatoon-2-surpasses-splatoon-lifetime-sales-japan-nintendo-games-continues-dominate-charts/ surpass sales of the original game]] by year's end, and just a week later, [[https://www.resetera.com/threads/splatoon-2-is-the-first-console-game-to-sell-over-2m-in-japan-in-8-years.15589/ become the first console game to sell 2 million units in Japan]] ''in eight years.'' It would take until March 2019 for ''Splatoon 2'' to be surpassed as the best-selling Switch game in the region (by ''VideoGame/SuperSmashBrosUltimate'') and leave the weekly Top 10 sales charts, and still remains one of the Top 10 best-selling games for the system globally.

* SequelFirst: The original ''VideoGame/{{Splatoon}}'' wasn't released in South Korea because the UsefulNotes/WiiU wasn't, but the UsefulNotes/NintendoSwitch and this game were.

** Had Team Callie won the final Splatfest back in [[VideoGame/{{Splatoon}} the first game]], Marie would have been the one to go missing instead.

** Also concerning Octolings, the original [[https://splatoonwiki.org/wiki/File:OctolingNoVisor.png art]] and [[https://splatoonwiki.org/wiki/File:OctolingPlayable.png model]] for the Octolings back in ''Splatoon 1'' featured ''purple'' eye lining, as opposed to the black domino-mask-esque markings of the Inklings; you don't get to see this in the game as published, but the art did show it off. The eye lining also markedly tapered away around their eyelids, eventually vanishing almost entirely. The eye lining also has a very notable "point" which angles toward the cheeks on each eye. The final playable Octolings in ''OE'', however, had some changes: while the general concept of the eye lining was kept, the color was shifted over to black in order to maintain better visual continuity with the Inkling player characters, and while the ''basic'' idea of the tapering at the eyelids was retained, the eye lining is still very visible on the upper parts of their eyes. The "point" was also retained, but was made significantly wider and more visually distinct, and more importantly, it became a visual feature exclusive to the ''girls''; the octo-boys simply have thicker lining around their lower eyes.

* FanNickname:
** ''[[{{Pun}} Splatwon]]'' (or variations such as ''[=Spla2n=]'' and ''[=Spla2oon=]'') spread like wildfire among the English-speaking community from the moment the original game became a hit, to the point where some fans were disappointed that the pun-loving Creator/{{Nintendo}} didn't utilize this title. ([=Spla2n=] could be clever, but Splatwon could just as easily be read as Splat-Twon. [[LostInTranslation Plus, the pun would only work in English anyway.]])
** Salmon Run Mode has been also dubbed "[[VideoGame/TeamFortress2 Squidd VS Salmonn]]" by some fans.
** The Splatfest-exclusive stage Shifty Station has been dubbed by several fans as the "[[Franchise/TheTwilightZone Twilight Zone]]" due to its Japanese name "Mystery Zone" being the same as the show's Japanese title.
** To differentiate playable Octolings from their enemy counterparts, which are both officially called "Octolings" in the Western versions, some Western fans call the enemy versions "Octozons", which comes from their official Japanese name, ''Takozonesu'' (''tako'' = octopus, ''amazones'' = amazons), while the playable versions are called ''Tako''.
** The Bloblobber is often referred to as the "Toilet" or "Kitchen Sink" due to its appearance.
** The fandom was ''really'' quick to notice that the "Booyah Bomb" special is a ''Splatoon''-ized [[Manga/DragonBallZ Spirit Bomb]], and commonly refer to it as such.
** The Clear Dapple Dualies are often referred to as the [[{{Portmanteau}} "Clapples"]].

** The fandom was ''really'' quick to notice that the "Booyah Bomb" special is pretty much a ''Splatoon''-ized [[Manga/DragonBallZ Spirit Bomb]], and commonly refer to it as such.

* [[RefittedForSequel Refitted for DLC]]: Many of the stage ideas and concepts used in ''Octo Expansion'' were initially planned for the base game's Hero Mode.

* AscendedFanon: Many fans were clamoring for a friendly Octarian; more specifically, people wanted playable Octolings. The developers delivered on the former with Marina, who quickly became a fan-favorite, and the latter with the ''Octo Expansion'' DLC.

* AscendedFanon: Many people were clamoring for a friendly Octarian. The developers delivered with Marina (one of the idols for this game, no less) who quickly became a fan-favorite. The ''Octo Expansion'' finally added the Octolings as playable characters.
* CanonImmigrant: The Milky Eminence gear set was based on a previously-fictional team uniform used by Emperor's gang in the second ''[=CoroCoro=]'' manga.
* {{Defictionalization}}: Rina Itou and Alice (the voice actresses for Pearl and Marina) ended up hitting it off quite well after working on the game, and the two of them would continue to do [[https://www.youtube.com/watch?v=jo5nBGpYoh8 their own music collaborations]] with Itou's band [=Lighter190E=].

** When the game went live on the Switch eShop in North America, users were unable to access it, repeatedly receiving error codes.

** Naturally, while the eShop itself survived thanks to preorders, the release of ''Octo Expansion'' brought Nintendo's distribution servers to their knees, resulting in many people taking ''hours'' to download the content, even on very fast connections.
