History YMMV / FlipFlappers

* EvilIsSexy: Welwitschia oozes it, thanks to her sexy servants and her rather intimate scene with Cocona.
** [[spoiler: Mimi]] invokes it somewhat, being a cold, ruthless and tsundere version of Cocona.

** Welwitschia in Episode 3. There's even implications about what she's planning to do with Cocona and Papika in her lair... [[WhipItGood and it won't be pretty...]]

* SpiritualLicensee: Some fans have called the series the closest thing we'll get to an ''Literature/AliceInWonderland'' adaptation that matches the tone and themes of the story.
** SpiritualSuccessor: To ''Anime/MiyukiChanInWonderland'', being a story about a girl stumbling through several surreal short events to discover her own repressed sexuality. It even has at least one incident be a groundhog day loop.

* LauncherOfAThousandShips: As one fan put it, "Everyone is [[SchoolGirlLesbians Yayaka]] for Cocona". There's been a select few people Cocona hasn't been shown with in fan works, and even then they have some sort of respect for her. [[spoiler: The last few episodes revise it to 'Everyone is Mimi for Cocona...']]

* EarWorm: The ending theme, "Flip Flap Flip Flap". It's an absolutely cheery tune that carries a sense of wonder in it. Not helped by the fact that [[TastesLikeDiabetes the animation that accompanies it is too cute for words...]]
** Notably, in the final episodes, [[TheDayTheMusicDied it vanishes completely, and the narrative takes a darker turn...]]

* AlternateCharacterInterpretation: What ''is'' the deal with Papika? Is she as air headed as she is because she's just a simple CloudCuckoolander? Or is she something else entirely? [[spoiler: Episode 3 seems to reveal that she's the missing part to a weapon, and that she's actually named "Papikana", so it seems like it's heading towards the latter interpretation.]]
** The [[spoiler: episode 3 name "Papikana" may be a subtitle error, and it's not at all clear that the thing she's one half of is a weapon or something else, like a magical girl duo. Episode 10 ''does'' reveal that the spelling is intentional, though.]]
*** [[spoiler: Episode 11 reveals that Papikana is the name she went by as an adult, something happening to deage her and have her use the more childish Papika, and the weapon comment was a red herring.]]
** There's one very simple and unified explanation for her brand of crazy which is overtly mentioned as a throwaway gag: [[spoiler: episode 3 has a goon say that he likes her name, that "Papika" reminds him of "Puppy". The girl introduces herself to Cocona saying "I waited forever for you!", is constantly sniffing the air and tracking people or things by scent, is frequently seen going about on all fours (especially in the beginning), plays Fetch with Cocona's glasses, goes all googly-eyed when she has an opportunity to chase a bunny, drools, and regularly puts inappropriate things in her mouth. She's clearly curious, and maybe even rather smart, but it's all instinctive reasoning rather than intellect or analytical intelligence. This is of course in addition to the ignorance of human norms.]] About the only quirk this little gag doesn't explain is her rocket-hoverboard habit and the rooftops it frequently lands her on.
*** Later debunked. [[spoiler: Papika, as Papikana, is shown helping Mimi court Dr. Salt, and she is a young woman in her 20's.]]

*** [[spoiler: Episode 12 shows that Papikana, Papika before her age decrease, knew Cocona from when she was originally born, and fell for her at first sight...]]

* UnfortunateCharacterDesign: Leading members of Asclepius's organization wear robes with conical, face-concealing headgear that appear to function as elaborate environment suits. While American viewers will readily make comparisons to TheKlan based solely on these outfits, given the organization's bearing and overall goal it is more likely that the outfits were meant to evoke the capirote, a traditional costume worn by Catholics in Spain during certain holidays and associated with punishment and penance. In this case, the outfits symbolize the organization's belief that their work ([[spoiler:to remake the world into a utopia by restoring and controlling Mimi]]) is an act of atonement or self-sacrifice on behalf of the world; this attitude sharply contrasts with the organization's highly unethical methods, ruthlessness, and [[spoiler:the apparent madness of Asclepius]].

* CounterpartComparison: Many viewers have likened Yayaka to [[Franchise/PuellaMagiMadokaMagica Kyoko Sakura]], for delinquent-style way of speaking, her more serious attitude in the plot and her [[spoiler:eventual transformation into a MagicalGirl]].

* OneTruePairing:
** While it has been somewhat split between who fans would rather pair Cocona with, it appears a majority prefer pairing her with Papika over Yayaka. [[spoiler:The fact Cocona and Papika become canon certainly helps.]]
** After it was revealed that [[spoiler:Mimi and Salt are Cocona's parents]] fans prefer pairing them together rather than pairing [[spoiler:Mimi]] with Papika.

* FanPreferredCouple:

* AwesomeArt: One thing that most people can agree on is that the art direction and the animation of the series is top quality. The picturesque landscapes coupled with the dynamic action of the Pure Illusion segments make it a treat to watch.

* TheyWastedAPerfectlyGoodCharacter: Though we learn about Toto, Yuyu, and Nyunyu being [[spoiler:{{Artificial Human}}s]], the plot ultimately doesn't do a lot with them, relegating the twins to simply Yayaka's partners and Nyunyu to the role of a Thomasson.
