History Flanderization / SpongeBobSquarePants

* [[Characters/SpongeBobSquarePantsSquidwardTentacles Squidward]]'s ButtMonkey role was transformed from mere LaserGuidedKarma to a mix of outright ComedicSociopathy and KafkaKomedy, with nearly every entity in Bikini Bottom genuinely out to make him miserable. This could be considered CharacterDevelopment since it made his {{Jerkass}} (admittedly with a [[JerkWithAHeartOfGold Heart of Gold]]) demeanor far more justified. [[TookALevelInJerkass Squidward's hatred of SpongeBob has also been Flanderized, though]]. For example, in "Christmas Who?", he gives away everything he owns so that [=SpongeBob=] won't cry. Episodes like "Gary's Got Legs" and "Broken Alarm" have Squidward outright gleeful at the idea of [=SpongeBob=]'s death, excitedly coming up with increasingly horrifying ways for it to have happened in the former. He also flies off the handle too easily and screams nearly every time he's on screen. Seriously, you'd be hard-pressed to find any post-movie episode where Squidward goes for more than 40 seconds without shouting his head off at [=SpongeBob=] or anything else that annoys him in the slightest.

* [=SpongeBob=] originally started out as a playful, naïve, eccentric, and happy-go-lucky ManChild who was optimistic, energetic and childlike to a fault. He would make most decisions on a whim and was mostly oblivious to how annoying and at times disruptive his unorthodox shenanigans were to his nextdoor neighbour Squidward and the Bikini Bottom public at large. He always wanted to make friends with and help out everyone in Bikini Bottom -- regardless of whether they liked it or not -- with varying results. To some Bikini Bottom citizens, he came across as a caring and generous NiceGuy with a heart of gold, and to others an over-the-top, clownish nuisance. Despite his actions often having unintended negative consequences, [=SpongeBob=] always had good intentions and was very eager to please. He was also, on occasion, able to demonstrate a somewhat mature attitude when the situation called for it.

* Patrick Star underwent two Flanderizations:

* Mr. Krabs went from being a typical [[PointyHairedBoss greedy yet usually well-intentioned boss]] to being borderline FauxAffablyEvil with an over-exaggerated MoneyFetish who would go through several kinds of hell just to retrieve a ''single penny''. One episode portrayed him as more obsessed with money as an ''object'' rather than for its value. While his greed was always prominent, he had some feasible redeeming aspects and morals to balance it out, his fatherly role with [=SpongeBob=] and Pearl for example. In later episodes, aside from some {{Jerkass}} qualities, his money-lust seems to be his sole defining trait, though this [[DependingOnTheWriter depends on the writer]]. In the first two seasons in particular he routinely was shown to have an emotional attachment to [=SpongeBob=] that has largely disappeared in later episode. It's also worthwhile noting that in earlier seasons, Krabs [[LaserGuidedKarma usually did receive his comeuppance]] every now and then with his ([[MoralEventHorizon sometimes morally questionable]]) schemes. In later seasons, this is the total opposite -- Krabs is practically one of the biggest examples of KarmaHoudini, considering that he somehow gets away scot-free with anything he does in those seasons (ranging from theft to poisoning his customers to even ''[[DrivenToSuicide driving people to suicide]]''), sometimes [[KarmicMisfire leaving someone to take the blame/pay the price]]. There are even times near the end of some episodes when it looks like Krabs is about to receive his comeuppance (or in rare cases, actually ''does''), but something happens at the end that puts the situation in Krabs' favor, if not lets him escape punishment entirely. On the other hand, he's been punished for his crimes in episodes such as "Patty Caper" and "The Cent of Money", and [=SpongeBob=] even calls him out for it on one occasion.

Seriously, you'd be hard-pressed to find any post-movie episode where Squidward goes for more than 40 seconds without shouting his head off at [=SpongeBob=] or anything else that annoys him in the slightest.

* Plankton's IneffectualSympatheticVillain role, to the point where he is arguably more likeable than [[DesignatedHero his nemesis]]. His more general plans of causing destruction have become less apparent as his desire for the Krabby Patty formula has evolved into an obsession. His [[AIIsACrapshoot sentient computer 'wife']], Karen's DeadpanSnarker mannerisms have also been upped to eleven.

** His Flanderization, which was first noticeable in Season 4 and became really apparent in Season 6, turned him into a gratuitously obnoxious, moronic, deranged toddler as opposed to the zany, enthusiastic {{Cloudcuckoolander}} he was in the first three seasons. He became extremely hyperactive and over-emotional, with a higher-pitched voice, a shriller laugh and a tendency to burst into tears far more often, and for longer ([[Recap/SpongeBobSquarePantsS7E10ADayWithoutTearsSummerJob there is even an episode about this incessant crying]]). His treatment of Squidward became stalker-level creepy, his antics crazier and more dangerous and his mindset considerably more ignorant and childish to the point where any remaining trace of his adulthood vanished entirely and so he needs to have basic concepts explained to him. Even his facial expressions became much more exaggerated to make him come across as mentally unstable; many modern production images (such as DVD covers) depict him pulling enormous open-mouthed smiles with dilated eyes and large rosy cheeks.

[[TookALevelInJerkass Squidward's hatred of SpongeBob has also been Flanderized, though]]. For example, in "Christmas Who?", he gives away everything he owns so that [=SpongeBob=] won't cry. In a later-season episode, when [=SpongeBob=] bursts into tears after Squidward convinces him that he can no longer laugh or smile again, Squidward just walks away with a smirk, saying "Oh, I hate it when he's sad. But I hate it even MORE when he's happy" (Though in that episode, he takes it back when he decides [=SpongeBob=]'s crying is worse than his laughter and tells [=SpongeBob=] the truth to make at least make it stop). He also flies off the handle too easily and screams nearly every time he's on screen. Seriously, you'd be hard-pressed to find any post-movie episode where Squidward goes for more than 40 seconds without shouting his head off at [=SpongeBob=] or anything else that annoys him in the slightest.

During Seasons 6-8, the characters of ''WesternAnimation/SpongeBobSquarePants'' have undergone massive {{Flanderization}}. However, while mostly undone from Season 9 onwards, their flanderizations are still prominent in some post-Season 8 episodes.

* Originally, Mrs. Puff was just a NoRespectGuy who didn't want to have to deal with [=SpongeBob=]'s bad driving. She was frustrated with his poor performance in her class, but genuinely wanted him to succeed and was generally nice to him outside of the classroom environment. Then she tried to ''murder'' [=SpongeBob=] in one episode after what she felt was the last straw (which apparently only lasted until the end).

* [=SpongeBob=] originally started out as a playful, naive, eccentric and happy-go-lucky ManChild who was optimistic, energetic and childlike to a fault. He would make most decisions on a whim and was mostly oblivious to how annoying and at times disruptive his unorthodox shenanigans were to his nextdoor neighbour Squidward and the Bikini Bottom public at large.

Despite his actions often having unintended negative consequences, [=SpongeBob=] always had good intentions and was very eager to please. He was also, on occasion, able to demonstrate a somewhat mature attitude when the situation called for it.

** Her insanity and tendency to get arrested also became far more prominent after the season 3 episode “Doing Time.” Moreover, while in the pre-movie episodes her arrests were all due to legitimate destruction and danger caused by her and/or her student [=SpongeBob=], in later years they were for increasingly petty reasons.

* Mr. Krabs went from being a typical [[PointyHairedBoss greedy yet usually well-intentioned boss]] to being borderline FauxAffablyEvil with an over-exaggerated MoneyFetish who would go through several kinds of hell just to retrieve a ''single penny''.

* Sandy, originally a science geek with OnlySaneMan tendencies, eventually gained a self-awareness of her [[ParodySue many talents]] and evolved into a rowdy Ted Baxter. They've also completely phased out her Texas Cowgirl tendencies for her scientist role, despite that her inventor traits were almost mute over the first few seasons.

* Plankton's IneffectualSympatheticVillain role, to the point where he is arguably more likeable than [[DesignatedHero his nemesis]]. His [[AIIsACrapshoot sentient computer 'wife']], Karen's DeadpanSnarker mannerisms have also been upped to eleven.

*** Nowadays, [=SpongeBob=] is a complete slave to the Krusty Krab and Mr. Krabs to the point of obsession. In the "Bummer Vacation" episode, he goes ''completely insane'' after being told to have a few days off from work. The yellow sponge also has no problems doing extra jobs on top of the ones he already has and goes along with any scheme Mr. Krabs gives him without a second thought. He doesn't even have a problem doing any of it for free; later seasons imply that he's working at the Krusty Krab for free or for less. Season 7 would show that he's okay with being paid with play money rather than actual currency. [=SpongeBob=]'s ambition is gone too, and he's completely content being a fry cook forever. In later episodes, [=SpongeBob=] would cover Squidward's and Mr. Krabs's jobs, and he'd be back in his previous post without fuss.

** [=SpongeBob=]'s attitude towards his job has changed too. At first, [=SpongeBob=] took great pride as the Krusty Krab's fry cook. He worked for pay like everyone else, like in "Krusty Krab Training Video", where he asked Mr. Krabs for a raise. Despite respecting Mr. Krabs, [=SpongeBob=] wasn't afraid to stand up to his boss when he was tired of his schemes; like when [=SpongeBob=] got tired of buying things for Mrs. Puff and fought back against Krabs when he captured the jellyfish. And like everyone else, he had ambition and wanted to become a manager; this was part of the plot in the movie. Though there were times [=SpongeBob=] liked his job too much (he broke down crying when he got fired the first time), it wasn't as bad as in later seasons.

Later seasons imply that he's working at the Krusty Krab for absolutely free or for less. Season 7 would show that he's completely okay with being paid with ''play money'' rather than ''actual currency''. [=SpongeBob=]'s ambition is gone as well, and he's completely content being a fry cook forever. Though in later episodes [=SpongeBob=] would cover Squidward's and Mr. Krabs's jobs, he'd be back in his previous position without complaint.

** His second Flanderization, which was first noticeable in Season 5 and became really apparent in Season 6, turned him into [[TookALevelInDumbass one of the]] [[TheDitz dumbest cartoon characters]], his actions even becoming dangerous at times. He has also [[TookALevelInJerkass taken multiple levels of jerkassery]]. In earlier seasons, Patrick was [[KindheartedSimpleton a nice, funny and lovable dimwit]] who had his jerky moments, but it was hinted that he was just [[InnocentlyInsensitive too dumb to realize the wrongness of his actions]]. However, his jerkiness got much worse and became much more frequent, up to FatBastard territory, going by the way he treats [=SpongeBob=] and Squidward on several occasions. Here are some examples:

*** In "The Splinter", he makes SpongeBob's infection from getting a splinter worse by putting a pile of garbage onto it, assuming that it would make it "better". He also doesn’t seem to focus on SpongeBob's splinter well, despite the latter's pleas to have his splinter be removed.
*** In "Big Sister Sam", he defends Sam's obnoxious behavior towards SpongeBob and Squidward and blames them for it.
*** In "The Card", he goes as far as [[ObfuscatingStupidity admitting that his stupidity is deliberate]] after walking through a whole bunch of dangerous places with a Mermaid Man trading card that he had bought for SpongeBob.

** His first Flanderization, which started around the end of Season 1, made him a lot more dim-witted and immature, sometimes stating bizarre non-sequiturs like "Is mayonnaise an instrument?". The animators would later accentuate his decrease in intelligence by giving him thicker, goofier eyebrows. During Seasons 2-4, his intelligence varies wildly; in one episode for example, he forgets he's eaten a chocolate bar only a few seconds after eating it, while in another he demonstrates the ability to pass a driving test after one try. He would also make an unusually intellectual statement once in a while, such as "The inner machinations of my mind are an enigma".
** His second Flanderization, which was first noticeable in Season 5 and became really apparent in Season 6, turned him into [[TookALevelInDumbass one of the]] [[TheDitz dumbest cartoon characters]], his actions even becoming dangerous at times. He has also [[TookALevelInJerkass taken multiple levels of jerkassery]]; in older episodes, Patrick was [[KindheartedSimpleton dumb, but nice and kind to his friends]], and occasionally acted like a jerk, but it was hinted that he was just [[InnocentlyInsensitive too dumb to realize what he was doing is wrong]], but his jerkassary became much worse and much more frequent, up to FatBastard territory, going by the way he treats [=SpongeBob=] and Squidward on several occasions, to the point where he arguably [[ObfuscatingStupidity admits his stupidity is deliberate]] in "The Card" after walking through a whole bunch of dangerous places with a Mermaid Man trading card.

** He began showing some early signs of Flanderization in Seasons 4 & 5 and when it became official in Season 6, he became a gratuitously obnoxious, moronic, deranged toddler as opposed to the zany, enthusiastic {{Cloudcuckoolander}} he was in the first three seasons. He became extremely hyperactive and over-emotional, with a higher-pitched voice, a more shrill laugh and a tendency to burst into tears far more often, and for longer. His treatment of Squidward became stalker-level creepy, his antics crazier and more dangerous and his mindset considerably more ignorant and childish to the point where any remaining trace of his adulthood vanished entirely and so he needs to have basic concepts explained to him. Even his facial expressions became much more exaggerated to make him come across as mentally unstable; many modern production images (such as DVD covers) depict him pulling enormous open-mouthed smiles with dilated eyes and large rosy cheeks.

The cast of ''WesternAnimation/SpongeBobSquarePants'' has undergone massive {{Flanderization}}, most infamously from its [[UnCanceled un-cancellation]] in 2005 (Season 4) to the release of the second movie in 2015. Some post-second movie episodes still Flanderize the characters, however.

* In the pre-Season 4 episodes, [=SpongeBob=] was characterized as a playful, naive, eccentric and happy-go-lucky ManChild who was optimistic, energetic and childlike to a fault. He would make most decisions on a whim and was mostly oblivious to how annoying and at times disruptive his unorthodox shenanigans were to his nextdoor neighbour Squidward and the Bikini Bottom public at large. He always wanted to make friends with and help out everyone in Bikini Bottom - regardless of whether they liked it or not - with varying results. To some Bikini Bottom citizens, he came across as a caring and generous NiceGuy with a heart of gold, and to others an over-the-top, clownish nuisance. Despite his actions often having unintended negative consequences, [=SpongeBob=] always had good intentions and was very eager to please. He was also, on occasion, able to demonstrate a somewhat mature attitude when the situation called for it.
** And then came his Flanderization, which grossly exaggerated every aspect of his personality and turned him into a gratuitously obnoxious, moronic, deranged toddler as opposed to the zany, enthusiastic {{Cloudcuckoolander}} he was in the first three seasons. He became extremely hyperactive and over-emotional, with a higher-pitched voice, a more shrill laugh and a tendency to burst into tears far more often, and for longer.

Even his facial expressions became much more exaggerated to make him come across as mentally unstable; many modern production images (such as DVD covers) depict him pulling enormous open-mouthed smiles with dilated eyes and large rosy cheeks.

** Patrick started out as an eccentric and fun-loving oddball who was slightly slow on the uptake but mostly intelligent (he even helped [=SpongeBob=] almost pass his boating test for the first time ever through radio; he immediately realized that Sandy's treedome was dangerous due to its lack of water; he was also able to pick up on Squidward's animosity towards him and [=SpongeBob=], while [=SpongeBob=] was completely oblivious to it).
** His first Flanderization, starting from the end of the first season, made him a lot more dim-witted and immature, sometimes stating bizarre non-sequiturs like "Is mayonnaise an instrument?". The animators would later accentuate his decrease in intelligence by giving him thicker, goofier eyebrows. In the second through fourth seasons his intelligence varies wildly; in one episode for example, he forgets he's eaten a chocolate bar only a few seconds after eating it, while in another he demonstrates the ability to pass a driving test after one try. He would also make an unusually intellectual statement once in a while, such as "The inner machinations of my mind are an enigma".
** His second Flanderization, first noticable in the fifth season and really becoming apparent in the sixth, resulted in him becoming [[TookALevelInDumbass one of the]] [[TheDitz dumbest characters on television]], his actions even becoming dangerous sometimes. Later seasons have also made Patrick [[TookALevelInJerkass take multiple levels of jerkassery]]; in older episodes, Patrick was [[KindheartedSimpleton dumb, but nice and kind to his friends]], and occasionally acted like a jerk, but it was hinted that he was just [[InnocentlyInsensitive too dumb to realize what he was doing is wrong]], but his jerkassary became much worse and much more frequent, up to FatBastard territory, going by the way he treats [=SpongeBob=] and Squidward on several occasions, to the point where he arguably [[ObfuscatingStupidity admits his stupidity is deliberate]] in "The Card" after walking through a whole bunch of dangerous places with a Mermaid Man trading card.

*** The reason he can't drive was changed as well. When it's first revealed that he failed the test 38 times, it's apparently because he gets nervous behind the wheel and panics. In newer episodes, he's a GiftedlyBad driver who puts everyone in Bikini Bottom in danger behind the wheel to the point where he's a [[PersonOfMassDestruction Sponge of Mass Destruction]]. It should say something that in the first episode he takes the test in he has no problem passing the Theory Test, but in a later episode he states that he was never able to get even a single question of the Theory Test right.

** [=SpongeBob=]'s attitude towards his job has changed too. At first, [=SpongeBob=] took great pride as the Krusty Krab's fry cook. He worked for pay like everyone else, like in "Krusty Krab Training Video", where he asked Mr. Krabs for a raise.

* Mr. Krabs went from being a typical [[PointyHairedBoss greedy yet usually well-intentioned boss]] to being borderline FauxAffablyEvil with an over-exaggerated MoneyFetish who would go through several kinds of hell just to retrieve a ''single penny''. One newer episode portrayed him as more obsessed with money as an ''object'' rather than for its value. While his greed was always prominent, he had some feasible redeeming aspects and morals to balance it out, his fatherly role with [=SpongeBob=] and Pearl for example. In later episodes, aside from some {{Jerkass}} qualities, his money-lust seems to be his sole defining trait, though this [[DependingOnTheWriter depends on the writer]]. It's also worthwhile noting that in earlier seasons, Krabs [[LaserGuidedKarma usually did receive his comeuppance]] every now and then with his ([[MoralEventHorizon sometimes morally questionable]]) schemes. In later seasons, this is the total opposite -- Krabs is practically one of the biggest examples of KarmaHoudini, considering that he somehow gets away scot-free with anything he does in those seasons (ranging from theft to poisoning his customers to even ''[[DrivenToSuicide driving people to suicide]]''), sometimes [[KarmicMisfire leaving someone to take the blame/pay the price]]. There are even times near the end of some episodes when it looks like Krabs is about to receive his comeuppance (or in rare cases, actually ''does''), but something happens at the end that puts the situation in Krabs' favor, if not lets him escape punishment entirely. On the other hand, he's been punished for his crimes in episodes such as "Patty Caper" and "The Cent of Money", and [=SpongeBob=] even calls him out for it on one occasion.
