"Hand over the secret Krabby Patty formula!"
English voice: Doug Lawrence
Latin American Spanish voice: Óscar Zuloaga, Luis Miguel Pérez
German voice: Thomas Petruo (Seasons 1 - 11) Sebastian Christoph Jacob (Season 11 - Present)
Debut: "Plankton!"

A tiny planktonic copepod with a Napoleon complex. With the help of his computer Karen, he runs the failing Chum Bucket restaurant across the street from the Krusty Krab. He is always after the secret Krabby Patty formula and dreams of running the Krusty Krab out of business.


  • Abusive Parents: Towards his and Karen's son Chip in "Karen's Baby". As Plankton never wanted a baby, he spends most of the episode going out of his way to avoid showing any affection towards Chip, including showing up his baby form's attempts to walk, refusing to help him stop crying and eventually outright telling his teenage form to run away. It takes Karen threatening to throw Plankton out if he can't find his son and said son's first word being "father" before Plankton finally accepts him as his son.
  • Affably Evil: He is no less pleasant than his rival can be anyway. This is best exemplified in the end of "Wishing You Well": Plankton, having been granted his wish to be taller, now towers over everybody and could smash the Krusty Krab if he felt like it. Instead, he jovially greets SpongeBob and Mr. Krabs before rampaging through the city, leaving them and the Krusty Krab completely unscathed.
  • Arch-Enemy: He is the main foe of Krabs, and sometimes SpongeBob.
  • Asshole Victim: He always meets his own end for trying to steal the formula, and needless to say, he's such a totally deserving victim. The only time his abuse was pitiful was in "One Coarse Meal", in which he becomes Driven to Suicide.
  • Ax-Crazy: Became one in the first movie. He is much more deranged, sadistic, depraved and homicidal than usual.
  • Badass Bookworm: He is shown to be a technological genius, capable of creating complex machines and powerful robots, as well as plotting various very elaborate, and nearly successful evil schemes.
  • Bad Boss: Plankton sometimes uses Karen as a guinea pig for his experiments.
  • Big Bad: The primary antagonist of both the series and The Movie, although Karen is the one giving him his plans in the film and most episodes.
  • Big Bad Wannabe: Usually, however, he's too incompetent to pull off a successful Evil Plan.
  • Body Snatcher: A few of his plans involve mentally or physically enslaving someone with or without them being aware of the situation.
  • Breakout Villain: Plankton was originally meant to be a minor character, as Stephen Hillenburg was initially unsure how to use the character beyond his debut episode. According to Mr. Lawrence here, Plankton "was only supposed to be in one or two episodes, but I was a writer on the show and I really liked this character." Lawrence wrote many plot outlines involving Plankton and Karen to prove that they could survive as more than one-offs, eventually turning the Planktons into the series villains.
  • Butt-Monkey: Just how many times has he been stepped on and thrown?
  • Can't Get Away with Nuthin': Not just with his evil plans:
    • A rather discomforting example would be "One Coarse Meal", where Plankton is punished for trying to exact justifiable revenge on Mr. Krabs, who in turn got off scot-free after tormenting Plankton non-stop for several days, to the extent that Plankton was nearly Driven to Suicide.
    • Plankton does partially get away in "Someone's in the Kitchen with Sandy". After yet another failed attempt to steal a Krabby Patty, he is locked in a jar of spicy mustard. Then the police show up and - instead of arresting Plankton for stealing Sandy's pelt - they arrest SANDY for public nudity.
  • Cardboard Prison: Plankton has been to prison a lot. However, no matter how many times Plankton is put in prison, Plankton will always end up out of prison the next episode he appears. Granted, he is small enough to escape through the bars after all, but even tiny prisons aren't going to be enough for him.
  • Card-Carrying Villain: He likes to talk about how evil he is.
  • Catchphrase:
    • "I went to college!"
    • "Ouch."
    • "Yes! YES!"
    • "I win! I WIN!"
  • Cephalothorax: His entire body is his face, just like SpongeBob. However, other plankton on the show are drawn like this, so this feat isn't exclusive to him.
  • The Chessmaster: In The Movie, he manipulates everyone to get the secret formula and to ensure Mr. Krabs' demise.
  • The Chew Toy: Most of the forms of Laser-Guided Karma he receives are meant to be amusing. The only time his abuse wasn't Played for Laughs was in "One Coarse Meal".
  • Corrupt Corporate Executive: Although the Chum Bucket could hardly be considered a corporation, he is an evil man bent on world domination in addition to trying to put his rival Mr. Krabs out of business.
  • Crouching Moron, Hidden Badass: In The Movie, proves to be way more competent than before.
  • Cut Lex Luthor a Check: Trope Codifier. He's clearly a brilliant inventor, with a huge cache of futuristic technology as his disposal, but it apparently never occurs to him to do something with his life other than running a rival restaurant to the Krusty Krab. Even then, he's apparently never considered that there are ways of running a profitable restaurant that don't require stealing your rival's recipes.
    • Though the main reason he keeps trying to steal the Krabby Patty recipe, is not so much because he hates Mr. Krabs, but because he himself couldn't cook to save his life so he tries to latch on to Krabs's success.
    • Also note that either way, Krabs is a ruthless competitor. There are in fact times Plankton has tried to make legitimate profits. Krabs still tries to ruin them and steal his customers, since either way he is his business rival and right next door to him at that. At times Krabs becomes so greedy and petty in bullying away profit that it seems this trope is there just to ensure he can still look like the good guy against Plankton.
  • Cyclops: Justified, he's a plankton and many plankton have just one eye.
  • Deadpan Snarker: Though not nearly as profound an example, he can dish sarcasm and witty retorts back to Karen at times.
  • Depending on the Writer:
    • How evil he is tends to vary from episode to episode. He's always a villainous character, but his antics are frequently overshadowed by Mr. Krabs later on.
    • How much he cares about Karen, if at all. Sometimes he genuinely cares about her and sometimes he has no problem expressing his contempt toward her.
  • Determinator: He won't stop no matter what gets in the way of his plans to get the secret formula. Much much more so in earlier episodes, but there are some later episodes in which he's given up.
  • Didn't Think This Through: A key reason why his Evil Plans almost constantly fail: Plankton repeatedly overlooks glaring flaws in his schemes and doesn't notice until it's too late for him to do anything about it. For example, in "Plankton's Army", a robot made to look like a customer enters the Krusty Krab. Mr. Krabs, smelling an obvious trap, takes Squidward's place at the register. To his astonishment, the robot just asks for coral bits and even pays him money after it's given its order. Suddenly, Plankton, who was hiding inside the dollar bill, pops out and gloatingly orders Krabs to hand him the secret formula. When Krabs responds, "Or what?", Plankton admits he never really thought the plan would get this far; Krabs responds by flushing Plankton down the toilet.
  • Ditzy Genius: He may be a scientist and have all sorts of gadgets, but is incompetent overall. For example, he believes that baby powder is made from actual babies in "Goo Goo Gas", and in "Komputer Overload", he has to be reminded to blink.
  • The Dog Bites Back: In "One Coarse Meal", when he nearly kills himself after being frightened by Mr. Krabs in disguise as Pearl from his fear of whales for 17 straight days, he finds out about Mr. Krabs's fear of mimes and starts scaring him with that. It doesn't last long, though.
  • A Dog Named "Dog": His nickname serves as this. He's a plankton addressed as Plankton.
  • Driven to Suicide: Almost deliberately got himself killed in "One Coarse Meal".
  • Embarrassing First Name: Karen had a really good time with this one. Once she learned her husband's given name was Sheldon in "Plankton's Army", her laughter and habit of displaying his name on a screen behind his back grew incessant to the point that Plankton had to turn her off.
  • Enraged by Idiocy: Like Squidward, he gets irritated when it comes to stupid people, particularly SpongeBob.
  • Establishing Character Moment: His very first appearance depicts him attempting to steal a Krabby Patty, and then vowing revenge on Mr. Krabs when the attempt fails.
  • Even Bad Men Love Their Mamas: Actually his grandmama. He's shown to care for his grandmother in "Gramma's Secret Recipe", though that doesn't stop him from stealing her wig and dentures to disguise himself.
  • Even Evil Has Loved Ones:
    • He truly loves and cares for Karen, but how he shows his love for her depends on the episode.
    • Plankton has his pet amoeba, Spot, who happens to be one of the only characters he will show genuine affection for, no strings attached.
  • Even Evil Has Standards:
    • In "The Krabby Kronicle", he doesn't invade people's privacy for a newspaper gossip and shows disgust at Krabs' greed. Quoted by him "And I thought I was evil!"
    • In "Squirrel Record", Sandy comes to him asking for raw chum in order to break a world record. Plankton is actually reluctant to give it to her despite freely admitting to being an "evil, heartless mastermind", because, as he puts it, "no one can eat raw chum and survive!"
  • Evil Cannot Comprehend Good: He often has trouble understanding basic concepts of goodness, such as having fun. In The Spongebob Movie Sponge Out Of Water, not only does he struggle to understand the concept of teamwork, he can't even pronounce it properly ("Te-am work? Tie-am? Time bomb... work?"). He also believes that SpongeBob helping him is really a front for a plot to steal the formula for himself, and is shocked to learn he really doesn't know it.
  • Evil Counterpart: To Mr. Krabs, at least in earlier seasons, since they both own rival fast food businesses and he behaved more like a supervillain than a mere unscrupulous businessman.
  • Evil Former Friend: To Mr. Krabs. It was the Krabby Patty Formula that caused them to become Arch Enemies with each other.
  • Evil Genius: He is shown to be a technological genius, capable of creating complex machines and powerful robots, as well as plotting various elaborate, and nearly successful evil schemes.
  • Evil Is Hammy: Despite his small size, he's hammy as hell.
  • Evil Laugh: He laughs evilly quite a lot.
  • Evil Sounds Deep: He's a villain with a deep voice. Downplayed later on the show.
  • Failure Is the Only Option: With an exception in "Wishing You Well", where his wish to be taller comes true, his schemes to get what he desires never work.
  • For the Evulz: As he freely admits in "F.U.N.", "being evil is too much fun."
    It's not worth it! It's! Not! Worth IT! Goodbye everyone, I'll remember you in therapy.
    Goes back to his timeline
  • Friendly Enemy: SpongeBob on many occasions tries to befriend or show pity on Plankton, with varying success.
  • Giftedly Bad: He's determined to destroy Mr. Krabs with his rival restaurant at the Chum Bucket, trying to market chum-related products to his customers even as he's trying to acquire the Krabby Patty formula. It has been shown that the food Plankton offers is simply unfit for consumption, driving away anyone who isn't already scared away by his cruelty. Plankton tries numerous ways to convince his customers his food is just as good as that of the Krusty Krab, but it usually only sickens whoever works up the nerve to try it.
  • Glad I Thought of It: He's guilty of taking credit for ideas other people come up with when he finds them pleasing, especially when he takes an idea Karen says to him.
  • Green and Mean: An evil, green copepod.
  • Green-Eyed Monster: He expresses his jealousy towards Mr. Krabs' success rate in the most diabolical ways possible.
  • Hair-Trigger Temper: He tends to get really angry when he's enraged in earlier episodes, he's calmed down a tad in later episodes.
  • Henpecked Husband: Has shades of being submissive around Karen.
  • Hoist by His Own Petard: Due to his inability to think his schemes through, said schemes always come back to bite him in the ass.
  • Idiot Ball: He varies from being on Sandy's level in terms of intelligence to being barely smarter than other characters.
  • The Igor: In "The Legend of Boo-kini Bottom", the Flying Dutchman ends up turning him into a deformed lackey who addresses him as "master".
  • I Just Want to Be Special: Plankton wants to have the same level of success as his archnemesis in the fast food industry, although the way he goes about it is repulsive, to say the least.
  • I'm a Humanitarian: "The Krabby Kronicle", as ode to Soylent Green, has Mr. Krabs force SpongeBob to write a news article claiming that Plankton makes his chum out of sentient fish.
  • Impossible Thief: In "F.U.N.", Mr. Krabs tempts a "reformed" Plankton with a Krabby Patty. Despite the fact that the patty is always visible and untouched on the table throughout the exchange, it somehow ends up replaced with a cardboard cutout, which Krabs should have seen from his angle, even when it was propped up.
  • Ineffectual Sympathetic Villain: He tends to be a pitiable and unsuccessful villain in later seasons, but it varies, as sometimes he manages to be the clear cut villain. Depending on the Writer.
  • Inferiority Superiority Complex: Plankton suffers serious insecurities based on his archnemesis' success. The episode "Friend or Foe" reveals his dynamic with Mr. Krabs and explains that he became a villainous Green-Eyed Monster over the latter's success as a business owner, while all Plankton could make was inedible chum.
  • Iron Butt Monkey: He gets hurt a lot, but he usually walks out of it okay. Deconstructed though, as while he can take a lot, it's strongly hinted that he became so resilient because he HAD to due his status as a plankton.
  • Jerkass: When he's the central villain of an episode, he'll be as mean as he is evil. In the episode "Plankton Gets the Boot," he falls into his analyzer, which describes him as "30% mean guy, 20% spiteful monster, 50% evil butt-head," and sums him up as "100% big jerk."
  • Jerkass Has a Point: In "Walking Small". True, he may have been using SpongeBob as an Unwitting Pawn at the time, but he nonetheless makes a valid point when he calls SpongeBob out on being an Extreme Doormat.
  • Jerk with a Heart of Jerk: In the first season episode "FUN", where his bonding with SpongeBob was just a ruse to get him to help him find the secret Krabby Patty formula. In episodes such as "Friend or Foe" and "Chum Caverns", when Mr. Krabs seems willing to let bygones be bygones, he always just takes advantage of the opportunity.
  • "Just Joking" Justification: At the end of The Movie, he attempts this, claiming that his mind-controlling everyone and turning Bikini Bottom into the dystopic Planktopolis was all a joke. Not one person buys it, and he's shipped off to prison, screaming that he'll destroy everyone.
    Plankton: Come on, I was just kidding. Come on, you guys knew that, didn't you? With the helmets and the big monuments...Wasn't that hilarious, everybody?
  • Knight of Cerebus: In The Movie, he's actually played seriously. Downplayed in the earlier episodes, where he was also played relatively seriously, but still had comedic moments here and there.
  • Large Ham: Particularly in earlier seasons, he has his moments of yelling at the top of his lungs and exhibiting No Indoor Voice.
  • Laser-Guided Karma: Many of Plankton's attempts to steal the formula prove to him that karma is a bitch.
  • Last-Name Basis: Though in his case, he prefers to go by his surname because he considers Sheldon an Embarrassing First Name. Unlike Mr. Krabs, he's simply called Plankton instead of Mr. Plankton (sans one episode where he sees what it's like if they switch places).
  • Laughably Evil: He's an Evil Genius who chews up the scenery.
  • LEGO Genetics: Happens to him at least twice:
    • In "The Inside Job", when Karen's gadget allows Plankton to steal the secret Krabby Patty recipe from SpongeBob's heart, he transforms into a Plankton shaped mini-SpongeBob. When he's extracted, the device attaches itself to Patrick, turning Plankton into a one eyed mini Patrick.
    • In "Salsa Imbecilus", after its suggested that the only way Plankton can get a hold of the Secret recipe is if Mr. Krabs was dumb enough to be tricked into giving it up he comes up with the idea to mix some of Patrick's genes into a soup he would give to Mr. Krabs in order to infect him with Patrick's (lack of) intelligence. It goes wrong when after tasting the soup, Plankton becomes as dumb as Patrick, leaves the stove on, which causes the soup to evaporate and condense into a rain cloud, which lowers the intellect of everyone in Bikini Bottom to the level of Patrick.
  • Leitmotif: In-Universe. He carries his gramophone to play his theme music, but only in his first appearance. It sometimes plays without the need of a gramophone.
  • Lethal Chef: The reason why he doesn't have customers. Not only is he a terrible cook, "Plankton's Regular" shows that his chum is actually poisonous to eat.
  • Likes Older Women: He is attracted to Mr. Krabs' mother in "Enemy In-Law", when he and Krabs are around the same age.
  • Lovable Rogue: Plankton plots the most devilish of schemes to get the formula, showing no regard to the lives of his targets whatsoever, yet that hasn't stopped the audience from finding him entertaining for nearly two decades.
  • Mad Scientist: Emphasis on mad. Quite a lot of his schemes involve using machines and concoctions that he created himself.
  • Major Injury Underreaction: He tended to react this way in the older episodes whenever his schemes backfired on him.
    Plankton: Ouch.
  • Manipulative Bastard: It would take more than two hands to count the amount of times he's deceived SpongeBob and Mr. Krabs into thinking that he Took a Level in Kindness just to get the formula.
  • Meaningless Villain Victory: Several episodes have him win, only for a last minute occurrence or revelation to render his victory pointless.
    • In "Plankton's Army", with the help of his brethren, Plankton manages to get into the Krusty Krab safe and procure the Krabby Patty formula. As he reads the ingredients out loud, he discovers that the most important one is four pounds of freshly ground plankton, which causes Plankton and his family to run out of the Krusty Krab screaming in horror. It's then revealed that what Plankton found wasn't even the real formula and that Mr. Krabs has the actual one in his home under his mattress.
    • In "Bucket Sweet Bucket", after tricking SpongeBob, Patrick, and Squidward into fixing up the Chum Bucket, Plankton manages to get into the Krusty Krab safe and find the formula, only for it not to be the formula, but a To Do list and that Mr. Krabs had the formula with him while he was on vacation. In addition, since SpongeBob and Patrick used the entire Krusty Krab to fix up the Chum Bucket, Plankton also lost his restaurant when Mr. Krabs pushes his back to its normal spot.
    • In "For Here Or to Go", Plankton enters a contest at the Krusty Krab where the prize is a free Krabby Patty (and he brings in a contest official that makes Mr. Krabs allow Plankton to enter). Plankton manages to win and despite Krabs's attempts to prevent the patty from being made, Plankton gets his patty, but has to eat it on the premises. However, Plankton makes it back to the Chum Bucket and has the patty analyzed before it's digested, with him selling Krabby Patties the next day. However, they taste awful, due to Karen having analyzed all the contents of Plankton's stomach, which in addition to the Krabby Patty also included things such as stomach acid and pills.
  • Naked People Are Funny: It is occasionally brought up that he doesn't wear clothes, like when he switches lives with Mr. Krabs in "The Algae's Always Greener" and is horrified to see that Krabs is naked since now he's the rival trying to steal the Krabby Patty formula from him. Plankton eventually explains in The Spongebob Movie Sponge Out Of Water that he goes naked because they don't make clothes his size.
  • The Napoleon: Being constantly stepped on and flung around like a piece of trash will mess with a plankton's mind, man.
  • Near-Villain Victory: "SpongeBob's Last Stand" is the closest Plankton has ever gotten in the cartoon series, with Mr. Krabs completely willing to hand over the secret formula. In one episode, he already figured out every ingredient in a Krabby, save for one, which was the Macguffin of that episode. This also goes for any scheme that DOESN'T involve stealing the secret formula.
  • Nice Guys Finish Last: Says this word-for-word in "Walking Small" when he tells SpongeBob that he's letting his niceness allow people to push him around.
  • No Celebrities Were Harmed: Voice actor Doug Lawrence modeled his voice off of Gregory Peck and Thurl Ravenscroft.
  • No Indoor Voice: Prone to speaking at the top of his lungs.
  • Not Me This Time: In "Patty Caper", he's naturally the first suspect when SpongeBob and Patrick try to find out who stole the key ingredient to the Krabby Patty formula. However, for once, it wasn't him.
  • Not-So-Harmless Villain: Played with in that his only interest is stealing Krabs' secret formula. However depending on his overzeal, he is willing to brainwash, potentially murder and generally cause a lot of collateral damage in his attempts to do so. In other episodes that aired after the movie, he even settles for just competing with Krabs legitimately. When he falls into his Analyzer in his debut episode, it describes him as being made of "1% evil, 99% hot gas."
  • The Noseless: Justified, planktonic organisms do not have noses.
  • Omnicidal Maniac: He vows to be one in the end of The Spongebob Squarepants Movie.
    Plankton: I will destroy all of you!
  • Only Sane Man: He's known to play this role whenever paired with SpongeBob and/or Patrick, as he has zero tolerance for their idiocy.
  • Paper-Thin Disguise: He has so many of these, and only SpongeBob is fooled by them.
  • Pet the Dog:
    • The episode "Plankton's Pet". He's genuinely nice to his pet amoeba Spot, feels guilty about having to punish him, and willingly works with SpongeBob to find him.
    • "Mimic Madness" has an example: when SpongeBob gets infected with Mimicry Madness, Plankton is actually willing to work with Sandy, Patrick, Squidward and Mr. Krabs to cure him, even to the point of (reluctantly) getting himself painted yellow to imitate the sponge.
    • Even after his scheme to steal the formula is quickly thwarted, Plankton has no qualms about helping SpongeBob's friends set up a birthday party for SpongeBob in "SpongeBob's Big Birthday Blowout".
  • The Pirates Who Don't Do Anything: He's ostensibly a chef/restauranteur, but it's easy to forget this when his status as a Card-Carrying Villain dominates his characterization, and when the Chum Bucket resembles a Supervillain Lair more than it resembles an actual eatery. He seems to spend more time plotting Mr. Krabs' downfall (and occasionally trying to Take Over the World) than, y'know...cooking food and trying to attract customers.
  • Psychopathic Manchild: He's a diabolical, immoral jerkass who has exhibited homicidal tendencies, wants to Take Over the World, manipulates and deceives SpongeBob on a recurring basis, and in general has little redeeming qualities. Despite this, he has a slight touch of innocence that makes him charming, as he's shown to enjoy SpongeBob's childish activities in "F.U.N.", owns a cute pet amoeba which he wholeheartedly cares for, occasionally responds with childish insults, and is shown watching hamster videos in some episodes.
  • Red Eyes, Take Warning: Subverted; he has a red eye, but he's usually pretty harmless despite being the Big Bad. Usually harmless.
  • The Rival: He is rivals with Mr. Krabs.
  • Running Gag: It's common for Plankton to be thrown out of the Krusty Krab to the Chum Bucket by Mr. Krabs.
  • Secondary Color Nemesis: A green copepod with a yellow eye who happens to be Mr. Krabs' Arch-Enemy and the Big Bad of the series.
  • Seldom-Seen Species: He's undoubtedly the most popular (and only) example of plankton in fiction. Most specifically (and a bit of a Genius Bonus to boot), Plankton is a Copepod, a small crustacean with one eye.
  • Sesquipedalian Loquaciousness: Often uses strong vocabulary.
  • Slasher Smile: He's particularly fond of these when one of his plans is actually working. He lets off an especially terrifying one with fangs near the climax of The Spongebob Squarepants Movie when Neptune is about to kill Mr. Krabs.
  • Smug Snake: Sometimes shown to be egotistical and arrogant toward others.
  • Species Surname: His full name is Sheldon J. Plankton, and he's a planktonic copepod.
  • Super Strength: Shown in "Bucket Sweet Bucket", where he crushes a nut with his teeth & punches the door off of a safe... from the inside, but normally subverted.
  • Swapped Roles: In "The Algae's Always Greener", Plankton creates a device that allows him to go into an Alternate Timeline where he is the owner of the Krusty Krab. He decides to go back to his own timeline after he experiences firsthand the nonsense that Krabs has to go through everyday in order to keep the restaurant in business.
  • Take Over the World: His secondary goal, Depending on the Writer, is to take over the world.
  • Throw the Dog a Bone: Gets a legitimately happy ending in both "Plankton's Pet" (where he gets a pet amoeba that he loves dearly) and "Wishing You Well" (where his wish to be taller comes true).
  • Tiny Guy, Huge Girl: The tiny guy to Karen's huge girl, as he's obviously shorter than her.
  • Took a Level in Badass: After a stint of Villain Decay, Plankton returned to his threatening and menacing self by Season 7 and became a much more competent villain. Particulary in the episodes "Frozen Face-Off", "SpongeBob's Last Stand", and "One Coarse Meal".
    • In "Frozen Face-Off", he organized a race as a distraction just so he could steal the Krabby Patty formula without trouble and to throw off the suspicion he placed his robot doppelgänger to participate in the race and it took the entire Krusty Krew plus Sandy and Karen to stop his Evil Plan.
    • In "SpongeBob's Last Stand", he took over the town when he built a superhighway over the Krusty Krab that directly led to the Chum Bucket and drove away all the jellyfish from their fields. Almost all of Bikini Bottom's population supported him until the jellyfish attacked them in revenge for their home's destruction. It was so bad that Mr. Krabs was going to give him the secret formula willingly. This and "Frozen Face-Off" are more dramatic and action-packed episodes of the series.
    • Even in "One Coarse Meal", where he was Driven to Suicide due to Krabs masquerading as Pearl and scaring him, Plankton was a very effective villain. He drops a powerful explosive the size of a TV remote on the Krusty Krab's roof; he is said to build a transmutator (a machine with the power to make an element in nature into another element, like iron into gold, fire into air, etc.); and a robotic bomb-shaped object that is actually a disguised, robotic, telescopic claw that can crush a sea creature. And at the end of the episode, Plankton uses mimes to scare Mr. Krabs, who is very afraid of mimes, as the revenge for Mr. Krabs scaring him and driving him to suicide and from looks of it, Mr. Krabs' fear of mimes is bigger than Plankton's fear of whales, since Plankton managed to remain rational while being scared by whales, while Mr. Krabs was completely irrational.
  • Took a Level in Jerkass: While Plankton was already something of a Manipulative Bastard and Jerk with a Heart of Jerk in the show's beginning, he became far more prone to committing crimes and attempting murder from the first movie onwards.
  • Tragic Villain: For some, he could be seen as a villain who deserves sympathy for the mishaps he went through that led to his path. It is known that as a child, he was bullied and his only friend was Mr. Krabs. Now he is evil and despises society, not only because of this, also for a dispute with Mr. Krabs for poisoning Old Man Jenkins.
  • Trash of the Titans: The Chum Bucket is often incredibly filthy to the point of crawling with cobwebs. Krabs lampshades it:
    Mr. Krabs: Criminy, Plankton! You ever hear of spring cleaning?
  • Used to Be a Sweet Kid: In addition to having formerly been friends with Mr. Krabs back then, Plankton used to be an innocent little boy devoid of malice.
  • The Unfettered: Depending on the Writer, he's willing to stoop to a lot of lows and do a lot of heinous acts to get the Krabby Patty formula.
  • Unknown Rival: Sometimes, SpongeBob fails to acknowledge him as an enemy.
  • Villainous Breakdown: He has one in The SpongeBob SquarePants Movie. After his helmets have been proven to be defeated by the Power of Rock, he resorts to desperately begging Karen to do something about SpongeBob. However, she was being carried off by the crowd and was too far away to hear her husband. As one final act of desperation to keep his control over the townspeople, he tried to command the brainwashed King Neptune to kill SpongeBob. Unfortunately for him, the helmet on Neptune's head was also destroyed, and he was freed from his mind control. Plankton then tried to escape through the front doors, only to be paved down by the freed Bikini Bottomites. He's later arrested, and he threatens to murder everyone once he gets out of prison.
  • Villain Cred: The episode "Jailbreak!" reveals that every other criminal in Bikini Bottom looks up to him; they outright describe him as "criminal royalty."
  • Villain Episode: "The Algae's Always Greener" (where he uses an invention to switch lives with Mr. Krabs just to see what his rival's life is like) and "Plankton's Army" (where he recruits his relatives to steal the secret formula) are a couple of good examples of episodes where Plankton is the main character.
  • Villain Protagonist: He's evil, but he's only the main character in some episodes, showing his attempts to steal the Krabby Patty formula.
  • Villain Song:
    'Plankton: ♪F is for fire that burns down the whole town, U is for uranium... bombs! N is for no survivors, when you-♪
  • Villains Out Shopping: In different episodes, he's shown doing such activities as watching TV ("The Inside Job") and playing chess with Sandy ("Mimic Madness") when not plotting to steal the Krabby Patty formula.
  • Vocal Dissonance: He has quite a deep, booming voice, in contrast to his minuscule size. Except in the Japanese dub, where he has a cutesy, high-pitched voice.
  • Vocal Evolution: Starting in the movie, he would develop a high-pitched scream.
  • We Used to Be Friends: He and Krabs were once friends since they were babies, but turned against each other after Krabs created the Krabby Patty and became more successful.
  • Why Did It Have to Be Snakes?: He has an absolute fear of whales as shown in "One Coarse Meal", to the point where the presence of them alone will drive him into a suicidal state. He doesn't seem to mind them in other episodes (e.g. "Jailbreak!", "Married to Money"), however.
  • Wounded Gazelle Gambit: Fakes an injury to get the Krabby Patty Formula in "Krabs vs. Plankton".
  • Xanatos Speed Chess: He's been shown to be quite adept at this in The Movie, where he quickly comes up with a last ditch scheme to put a mind-control bucket on King Neptune's head to kill Spongebob and Patrick.
    Spongebob: Sorry to rain on your parade, Plankton.
    Plankton: Oh, my parade will be quite dry under my UMBRELLA!
  • Yank the Dog's Chain: Happens to him an abundance of times, as anytime he gets his hands on the Krabby Patty formula, he'll eventually have it taken away from him in one way or another or realize how fatal it was. The most prominent example yet occurs in the first movie, in which Plankton finally obtains the formula, attracts business, and takes over the world to drive it home...until SpongeBob frees all the citizens from his mind-control helmets and Plankton serves a life sentence for his terror.
  • Your Cheating Heart: Plankton tries to marry Mr. Krabs' mother in "Enemy In-Law"...while still married to his computer wife. Luckily for the latter, his plan is ultimately foiled.
  • Your Size May Vary: We all know that Plankton is small, but how small he is has a tendency to vary, ranging anywhere from a few inches tall to borderline microscopic. This is especially the case in his debut episode.

    Karen Plankton 

Karen Plankton

https://static.tvtropes.org/pmwiki/pub/images/spongebob_karen.jpg
"Today is the perfect day to steal the recipe!"
English voice: Jill Talley
Latin American Spanish voice: Melanie Henríquez, Sofía Narváez
German voice: Susanne Herrmann
Debut: "Plankton!"

A waterproof supercomputer who runs the Chum Bucket alongside her husband Plankton. She is always giving him new evil plans to steal the Krabby Patty formula, but their efforts never succeed. Karen is Plankton's own invention, and her software is built into most of his machines.


  • Actually Pretty Funny: Sometimes laughs with the good guys against Plankton.
  • All There in the Script: Her name wasn't mentioned at all in the "Plankton!" episode, but it was listed in the credits.
  • Armless Biped: In the movie and most episodes from season 5-9, her mobile form does not have arms. From season 10 onwards, however, her mobile form always has them.
  • Beleaguered Assistant: She mostly averts this as she is generally the dominant one in the relationship.
  • Berserk Button: She has one in "Plankton Gets The Boot". Don't insult Karen's new screensaver or saying it makes her processor look fat. Plankton learned that the hard way, twice.
  • Big-Bad Ensemble: She and Plankton tend to be the main villains of the show.
  • Breakout Villain: As mentioned above, Mr. Lawrence was responsible for turning the Planktons from one-off characters into the main villains.
  • Character Development: She shows no signs of sentience in "Plankton!" but gains her personality in "F.U.N." However, she did always have a Midwestern accent, as mentioned in Just a Stupid Accent below.
  • Cuteness Proximity: She gets so excited over how adorable Spot's puppies are in "Spot Returns" that she shuts down and spends several hours needing to be rebooted. When she comes back online and discovers even more puppies, she's even happier.
  • Deadpan Snarker: In the post-movie episodes, she snarks at Plankton all the time.
  • Early Installment Character-Design Difference: She was only seen in wall form until the first movie and season 4.
  • Equippable Ally: She is equippable with lasers, screensavers, and various software.
  • Flanderization:
    • Her sentience and, to a lesser but still noticeable extent, her Deadpan Snarker mannerisms. In the first season, she was always supportive of Plankton and focused on the mission. In the first movie, she became deadpan almost all of the time. While she has mostly reverted to her more cheerful demeanor as of season 9, she still shows signs of getting fed up with Plankton's ignorance at times.
    • One aspect of her personality that was completely phased out was her unquestioning servitude to Plankton. She always helps with his plans and gives them to him in most cases, but she no longer does whatever he says when he demands it.
    • An example of her unquestioning servitude can be seen in the Season 3 episode "The Algae's Always Greener". Plankton orders Karen to make him some dinner, so she gives him holographic meatloaf while saying—in a completely serious, non-sarcastic manner—"Yes, your majesty."
  • Hyper Competent Side Kick: She successfully stole a Krabby Patty the first time she tried alone, with near zero effort (then again, it was against Squidward).
  • Interspecies Romance: If a computer counts as a species, her and Plankton counts as a relationship between people of different species.
  • Just a Stupid Accent: Had a very obvious Chicago accent even before she had a personality.
  • Lack of Empathy: She even says to SpongeBob that she cannot feel for others because she physically does not have a heart.
  • Non-Indicative Name: Her full name is Karen Plankton, but she's a computer, not a plankton.
  • Non-Standard Character Design: Karen is the only one who is regularly drawn with wavy-lined borders instead of clean lines. This is because backgrounds and items in the show are normally drawn with wavy borders while characters aren't.
  • Only Sane Woman: Typically one to call Plankton out on his obsessive schemes, more so currently.
  • Pet the Dog: She is a computer but nevertheless has a very strong love for Plankton deep down.
  • Ridiculously Human Robots: Played with. She supposedly has no heart but still feels a wide range of emotions. However, she still has some limitations such as being unable to eat (though she is turned into a Krabby Patty zombie in "Krabby Patty Creature Feature" when she is force-fed bits of the Krabby Patty zombies by having them stuffed into her disc drive).
  • Robotic Spouse: Yes and no. Yes, Karen is a robot and she married her creator. But no, Plankton did not create her just to marry her. She was originally just the security system for the business he and Mr. Krabs ran together, before they began dating naturally. Their romance even began before Plankton became evil, and Karen was so faithful to him that she became evil as well.
  • Satellite Character: She usually only interacts with Plankton and whoever else comes into the Chum Bucket. Justified, seeing as she's a mostly immobile computer who was permanently stationed in the Chum Bucket for the first four seasons.
  • Satellite Love Interest: Averted, since she wasn't written as Plankton's wife until Season 3 and is actually a formidable villain rather than just a love interest, having come up with almost all of Plankton's schemes herself.
  • Sir Not-Appearing-in-This-Trailer: She plays crucial roles in both movies (authoring and telling Plankton about "Plan Z" in the first, powering the time machine in the second) but did not have much screen time in the trailers for them. However, she was featured in the associated merchandise, such as the Mega Bloks time machine playset for the 2015 movie.
  • Snarky Inanimate Object: She's a robot and is pretty snarky in the later episodes.
  • Snarky Non-Human Sidekick: She's a robot who aids Plankton in his plans and is prone to making snide remarks toward him.
  • Talking Weapon: She has robotic abilities like lasers and death rays that make her a talking, walking weapon sometimes.
  • Tiny Guy, Huge Girl: The huge girl to Plankton's tiny guy, since she's a large computer and he's a tiny crustacean.
  • Took a Level in Cynic: She inexplicably becomes far more cold-hearted than usual in the first movie.
  • Tuckerization: Named after Stephen Hillenburg's wife.
  • TV Head Robot: The head of her mobile unit looks a lot like a CRT television.
  • Women Are Wiser: She is much more clever and competent than her husband Plankton.

    Sandy Cheeks 

Sandra Jennifer Cheeks

https://static.tvtropes.org/pmwiki/pub/images/spongebob_sandy.jpg
"Don't you dare take the name of Texas in vain!"
English voice: Carolyn Lawrence
Latin American Spanish voice: Mercedes Prato, Anabella Silva, Yaraivi Acevedo, Lileana Chacón
German voice: Cathlen Gawlich
Debut: "Tea at the Treedome"

An athletic, thrill-seeking squirrel from Texas who loves her home state. She works as a scientist and lives in an underwater dome full of air. She usually wears a bubble-helmet diving suit when she is outside of her home.


  • Academic Athlete: She qualifies even if the show is not set in a school. She's probably the most academically inclined character with a vast knowledge of science, and also a Passionate Sports Girl who excels at karate.
  • Action Girl: Much more so in earlier episodes, though it still shows through every now and then. It's often shown that she's very strong, occasionally so much that she easily defeats SpongeBob, as tough as he is to damage, in Kung-Fu battles.
  • Adorkable: Like her friend SpongeBob, she's cute and eccentric. Not to mention extremely nerdy, which causes SpongeBob and Patrick to often scratch their heads in confusion whenever she talks science.
  • Animals Not to Scale: She's rather small for a squirrel. In Sponge Out of Water, she's smaller than a human's foot.
  • Ax-Crazy: If her hibernation is interrupted, she turns into a rabid, feral beast.
  • Badass Adorable: An extraordinarily strong and intelligent female squirrel who manages to live underwater. Does more need to be said?
  • Badass Bookworm: She is extremely intelligent and often shown to be extraordinarily strong. Also likes life-threatening stunts.
  • Bare-Fisted Monk: She's a master of Karate, and it's part of how she and Spongebob initially bonded.
  • Bare Your Midriff: When she's not wearing her suit filled with oxygen, she wears a purple bikini top and green panties with a purple skirt, leaving her midsection exposed.
  • Berserk Button: Never ever insult anything/anyone from Texas, or even the state itself. You will regret it, as SpongeBob and Patrick faced the serious consequences.
  • Big Sister Instinct: She's frequently portrayed as immediately defending SpongeBob from terror.
  • Break the Haughty: Suffers it in "Sandy, SpongeBob, and the Worm". She goes to take out the Alaskan Bullworm for the sake of the town, and adamantly refuses to listen to SpongeBob's warnings about how big and monstrous the thing is, convinced she's "too Texas-tough" and can easily handle the worm. In the end, she comes across the worm in a cave and apparently beats it...only to discover that what she fought was actually the worm's tongue, and the Bikini Bottomites were not exaggerating over how big and monstrous it is; all of her bravado fades in an instant.
  • Broken Ace: She tends to be competent and highly skilled at everything she does. However, she suffers a light case of this in some episodes, due to her very competitive attitude. She takes the idea of not being the best at something rather badly.
  • Bullying a Dragon: Combined with Break the Haughty. Despite the Bikini Bottomites and SpongeBob's constant warnings about how big and monstrous the Alaskan Bull Worm was, Sandy refuses to take them seriously. This bites her in the butt when she finds out that the "worm" she was fighting was actually it's tongue. Sandy then realized that she was seriously outclassed and runs for her life.
  • Characterization Marches On: Her scientific nature wasn't shown as much in the pre-movie era. It wasn't until Season 4 that her inventor personality was established.
  • Chaste Toons: "Sandy's Nutty Nieces" reveals she has three nieces.
  • Competition Freak: Sandy is used to being the best at multiple talents and sports, so gets rather aggressive with when challenged.
  • Cool Big Sis: Her relationship with SpongeBob can be rather brotherly-sister in that the former looks up to her and they get into conflicts often but always come out clean.
  • Cute Bruiser: She is clearly one of Bikini Bottom's strongest residents, if not the strongest. She occasionally challenges massive, heavily muscled beachgoers to weightlifting challenges.
  • Deadpan Snarker: Has become quite a bit of one in the later episodes, particularly in "Planet of the Jellyfish" and "It's a SpongeBob Christmas!"
  • Demoted to Extra: Sandy appeared significantly less from Season 3 onwards, being more of a recurring supporting character than the main character she was originally billed as. Later seasons have attempted to avert this, with seasons 8, 9 and 11 in particular giving her plenty of focus episodes.
  • Early Installment Character-Design Difference: In the first season, her tail wasn't outside her suit, and the patch on her suit was three black dots instead of her signature acorn.
  • Enraged by Idiocy: Not to the extent of Squidward, but she quite expresses her annoyance towards people's stupidity, particularly when it regards Patrick on occasions like in "I Had An Accident" for instance.
    Sandy: (to Patrick) Don't you have to go be stupid somewhere else?
  • Establishing Character Moment: The first time Sandy is seen on-screen, she's shown fighting a giant clam, ultimately cementing her strength and masculinity.
  • Everything Is Big in Texas: She's the size of a flea compared to the Texas landscape.
  • Fish out of Water: Played straight, though she's actually a squirrel IN water. Her troubles fitting in with an underwater society aren't as apparent in the later episodes, though.
  • Foil: To SpongeBob. While both of them are Adorkable, energetic and eccentric Ridiculously Cute Critters who like karate, their personalities differ in that:
    • SpongeBob is a naïve and kooky Ditz who's childish, pestering, wimpy, cowardly, and generally ignorant in all but a few topic areas,
    • Sandy is a mature, tough, bold, and intelligent individual who more often than not plays the Only Sane Woman role.
  • Flanderization: Originally portrayed as The Ace in various activities, post-movie episodes have increasingly focused on her being a scientist, pretty much shunning anything else she was passionate about.
  • Flat Character: Became lacking in characterization in the post-movie seasons, as more focus was given on her intelligence and competence in fields dealing with science.
  • Four-Temperament Ensemble: The Choleric (shares this with Mr. Krabs). She's task-oriented and likes a challenge.
  • Forgot Flanders Could Do That: Any time the writers remember her Texan background or her other talents besides science.
  • Gadgeteer Genius: She built tons of nifty gadgets.
  • Genius Bruiser: She's athletic, tough, and loves karate, while also being an extremely smart scientist.
  • Genki Girl: She can be excitable and cheerful when she wants to have a good time.
  • Hair-Trigger Temper: Usually level headed, but being a Hot-Blooded Texan, she is rarely subtle when her temper flares.
  • Idiot Ball:
    • Holds this in "Prehibernation Week", where she takes SpongeBob along with her to perform extreme stunts with little regard to his deteriorating health. This doubles as Jerkass Ball.
    • She invokes this on herself in "Squirrel Jokes" in retaliation against SpongeBob's bigoted humor about her species, showing him how toxic it would be to have a friend who's Too Dumb to Live.
  • Insufferable Genius: Sometimes can be insufferably boastful about her intellect, especially in later seasons.
  • Invisibility: She can turn invisible as Miss Appear in "Mermaid Man and Barnacle Boy V".
  • Jerkass Ball: In spite of her overall kindness, she can be quite an Insufferable Genius and egotistical jerk at times, and occasionally forces the others to do excruciating activities with her when it dangerously affects their health.
    • In "Prehibernation Week", she forces SpongeBob along with her in her extreme sports activities, which clearly have an adverse affect on his health, not that Sandy seems to care.
    • In "Kenny the Cat", she exposes the eponymous character as a fraud in front of his fans and forcefully kicks him to the top of the ocean's surface despite him having done nothing to provoke her.
  • Just Friends: In spite of the Ship Tease, her relationship with SpongeBob seems to be platonic for the most part.
  • Lethally Stupid: In "Prehibernation Week", and only that episode. She forces SpongeBob to take part in a series of life-threatening sports and seems oblivious to his despair even as he screams and cries. After SpongeBob decides to hide from her, she rallies the entire city to search for him, ordering them to repeatedly venture into dangerous places and refusing to let any of them sleep.
  • Lightning Bruiser: She's very strong (as mentioned above in Cute Bruiser), tough (goes through very hard physical training, such as looking for a SINGLE STRAND OF HAY in a HUGE PILE OF METAL NEEDLES without getting hurt or tiring out) and is also very agile (especially considering she is wearing a heavy suit and is reasonably fast even while under water pressure).
  • Like Brother and Sister: While there has been some romantic connotations in their friendship, she and SpongeBob have a brotherly-sister relationship, enjoying each other's company and performing karate together, albeit not without having their squabbles.
  • Made of Iron: Thanks to Super Strength, Sandy has survived many fatal accidents and near-death experiences in ways that SpongeBob wouldn't.
  • Masculine Girl, Feminine Boy: Masculine Girl to SpongeBob's Feminine Boy. Sandy is characteristically tough in that she has survived the most fatal obstacles, practices extreme sports, fought a giant clam by which she was nearly eaten, and is proficient in hardware; SpongeBob is a wimpy coward who's In Touch with His Feminine Side, unable to stand up for himself, sports a very girly appearance, and has cross-dressed on a few occasions.
  • Ms. Vice Girl: She is a scientific genius, physically robust to superhuman levels and thoroughly optimistic and friendly on top of that. However, perhaps because of her many strengths and talents, she often displays an ego problem, which can lead her to be very aggressive and competitive when someone challenges her.
  • Muscles Are Meaningless: Played With in that the art style doesn't depict her as being muscular, but a few close-ups and occasional flexes do indeed show her with muscles, even being able to grow them by force (most notably in "Karate Island", but also in "MuscleBob BuffPants", "Christmas Who?", and "Whelk Attack").
  • Nice Girl: Sandy's a happy and friendly squirrel.
  • Ninja Pirate Zombie Robot: A sea-dwelling squirrel that dresses like an astronaut to cope with the environment, Sandy's love of science and karate is surpassed only by her love of her home state of Texas.
  • Noble Bigot: In "Pressure", she repeatedly bragged that land creatures are better than sea creatures, with SpongeBob, Patrick, Squidward, and Mr. Krabs thinking the opposite. However, after their attempts at proving it put both sides in mortal danger, they grow out of it.
  • Not So Above It All: Sometimes, her sciencey-mind can make her do some things that push her into Mad Scientist territory.
  • Ocular Gushers: In "Texas", her longing for her eponymous hometown causes her to cry an abundance of tears in her helmet, so much to the point where there's a flusher installed in it to drain them.
  • Odd Friendship:
    • Her friendship with SpongeBob could qualify, as while both of them like karate, Sandy is far more intelligent and mature than the dizty, goofball sponge, thus their relationship seems to be more brotherly-sister than genuine.
    • Same goes for her friendship with Patrick, although they rarely interact one-on-one and Patrick usually only goes to her house as SpongeBob's tagalong. Despite their differences, they seem to get along well enough despite some disagreements regarding their vast difference in intellect.
  • Only Known by Their Nickname: The only times she was referred to by her first name were in "Patrick SmartPants", "Atlantis SquarePantis", and "Two Thumbs Down".
  • Only Sane Woman: Not as sane as Squidward, but she's still fairly level-headed. Not so much before hibernation, though, as apparently the first stage of hibernation involves losing your mind. Apparently, her not being a jerk or an idiot is why Squidward gets along better with her than with the others.
  • Parody Sue: A few episodes, especially in the 2nd season, seem to make light of her somewhat lengthy amount of talents and positive aspects, it also usually being these points she was portrayed in a more flawed light.
  • Passionate Sports Girl: To a particularly extreme level. Adding to that her occasional Competition Freak bouts, working out with Sandy can border out and out life threatening.
  • Pint-Sized Powerhouse: While she's rather short in height and depicted as a weakling by the art style, she has performed the most badass of defeats for a squirrel in an astronaut suit.
  • Platonic Life-Partners: She's close friends with SpongeBob, and while there have been some definitive Ship Tease moments between the pair, their dynamic hasn't shown any explicit romance.
  • Positive Discrimination: Is a female mammal and the most gifted and least flawed central character by miles, though partly due to excessive Flanderization of the bipedal, male characters. Admittedly, it is also balanced by frequent Not So Above It All moments. She played it undeniably straight pre-Character Development however.
  • Ship Tease:
    • Usually with SpongeBob, shown by how well they interact with one another, and some reactions to each others comments. One Flashback from "Truth or Square" even had them seemingly getting married, only for it to be revealed as a play after an Almost Kiss. Carolyn Lawrence, Sandy's voice actress, has admitted she believed that both characters have romantic interest in one another.
    • She also has some ship tease with Larry in "Ripped Pants", overlapping with her relationship with SpongeBob and seeming a bit like a Love Triangle on her part. The latter is greatly affected by Sandy choosing to interact with Larry over him (though SpongeBob brought this betrayal on himself as he went too far and faked a near-death experience just to make another joke about his pants).
  • Slapstick Knows No Gender: Not as much as the others but Sandy suffers some physical damage at times, such as being mauled by a gorilla, having her fur torn off by SpongeBob and Patrick, being plagued with fleas, being hit by a car off of a mountain and so on.
  • Small Name, Big Ego: Albeit not as consistently as Squidward, she can overestimate her own abilities. Here are some examples:
    • In "Pressure", she repeatedly stated that land creatures are better than sea creatures and went so far as to almost drown herself in an attempt to prove it.
    • In "Sandy, SpongeBob, and the Worm", she was firmly convinced that, being "Texas tough", she could easily handle the Alaskan Bullworm, repeatedly dismissing and even mocking SpongeBob's warnings. When she finally reaches it and finds out that the Alaskan Bullworm is indeed as big and dangerous as everyone said, she runs in fear, and only admits she was wrong after SpongeBob nagged her into doing so.
  • Southern-Fried Genius: She's a genius from Texas, and proud of it!
  • Stronger Than They Look: From a first glance, Sandy looks no stronger than SpongeBob (who, needless to say, is a weakling), however when she's faced with fatal near-death experiences, she absolutely aces it when it comes to overpowering her obstacles.
  • Super Strength: Pretty obvious, actually. Especially when you see her pull a boat underwater by the chain in "Sandy, SpongeBob, and the Worm".
  • Team Mom: Unlike most other Only Sane Man characters on the show, who are usually Jerkasses, Sandy has shown herself able to deliver logic and reason to SpongeBob and Patrick constructively and in a way that doesn't come off as abrasive.
  • Tertiary Sexual Characteristics: She wears a flower on her diving helmet so it's more readily apparent she's a girl. She's got eyelashes too, but so does SpongeBob.
  • Token Good Teammate: One of the only characters who hasn't been turned into either a Jerkass or a moron. She and Pearl are also the only characters Squidward gets along with very well for this reason. Her occasional ego and temperament can provoke some unfortunate situations in the show (eg. "Pressure"), that said, she is arguably the one recurring character that hasn't had her flaws Flanderized over her redeeming aspects.
  • Tomboy: Sandy's a muscular squirrel girl with a passion for sports and science.
  • Tomboy with a Girly Streak: Sandy may always be up for tough fun or a science experiment, but she's not quite The Lad-ette. She regularly wears a pink decorative flower on her helmet and nothing but her bikini in her treedome, openly cries over her isolation from her hometown, and perhaps most prominently, is not above venturing into typical Gossipy Hens nighttime behavior with Karen and Mrs. Puff (who are apparently gal pals with each other) in "Girls' Night Out".
  • Tomboy and Girly Girl: The karate chopping techno whiz Tomboy to Pearl's Girly Bratty Teenage Daughter.
  • Tomboyish Voice: Although, it's more Southern than tomboyish.
  • Too Clever by Half: Every now and then she goes into being so smart that it puts her at a disadvantage.
  • Toon Transformation: She was a live-action squirrel when she lived in Texas, but she became animated like the rest of the residents of Bikini Bottom when she moved there.
  • Trademark Favorite Food: She likes eating nuts and anything nut-related. Give or take, she's a squirrel.
  • Walking Swimsuit Scene: Occasionally seen in a bikini, but always when she's in her tree house.

    Mrs. Puff 

Poppy Puff

https://static.tvtropes.org/pmwiki/pub/images/spongebob_mrspuff.jpg
"In all my years of teaching, only one student has ever failed my class."
English voice: Mary Jo Catlett
Latin American Spanish voice: Isabel Vara
German voice: Rita Engelmann (Episodes 4-182, first movie), Joseline Gassen (second movie), Sonja Deutsch (Episodes 190-present)
Debut: "Boating School"

SpongeBob's patient but paranoid teacher at boating school. She would like nothing more than to pass SpongeBob since he is an obsessively good student, but he routinely freaks out and crashes whenever he has to get inside a boat. She is a pufferfish who blows up into a ball whenever she is scared or stressed out.


  • Alliterative Name: Poppy Puff.
  • Ambiguous Disorder: Several episodes demonstrate that SpongeBob's antics have taken quite the toll on her mental health. "Doing Time" ends with her having repeated hallucinations of the episode's beginning, and in "Krusty Love", she has a very PTSD-like reaction by just hearing SpongeBob's voice. Though she's still able to calm down when he points out they're not driving.
  • Apathetic Teacher: Zigzagged, Depending on the Writer. Though it's mostly her attitude toward SpongeBob since no matter what she does, she can't seem to get him to pass the driving portion of her test and out of her hair for good. His over-eagerness certainly doesn't help, neither does continually landing her in jail either.
  • Ax-Crazy: In "Demolition Doofus" when she becomes obsessed with attempting to get SpongeBob killed in a demolition match, and tries to kill him herself when that fails.
  • Big Eater: She's shown to have a big appetite. See Obsessed with Food below.
  • Butt-Monkey: As a result of SpongeBob's antics, she's frequently injured or sent to jail.
  • Commonality Connection: When Squidward has to attend her classes, they bond over the fact that SpongeBob is the bane of both their existences.
  • Cool Old Lady: She is surprisingly active for an elderly teacher and even has an expansive criminal record.
  • Dark and Troubled Past:
    • According to at least one monologue, she has previously skipped town under a different name.
    • Her husband was apparently fished up out of the sea and made into a lamp.
  • December–December Romance: She and Mr. Krabs are close to being senior citizens and have each been married before, but that doesn't stop them from falling in love and continuing to date (for nearly two decades, as revealed in Whirly Brains).
  • Deadpan Snarker: SpongeBob's annoyance and idiocy often causes Mrs. Puff to snide and make sarcastic remarks.
  • Determined Widow: Amazingly, she has made it her goal never to give up on SpongeBob, no matter how many times he fails.
  • Didn't Think This Through: She falls victim to this in the episode "No Free Rides". Sick and tired of having to go through SpongeBob's chaotic driving tests, she comes up with a bogus extra credit test to just give him his driver's license and get him out of her classroom. It's only after she does so that it hits her that she has just given SpongeBob free reign to drive on public streets and wreak havoc there.
  • Early Installment Character-Design Difference:
    • She has much more wrinkles in her first appearance.
    • "Boating School" had her puff up a little whenever she inhaled. Now, she only puffs when she is surprised or injured.
  • Establishing Character Moment: The first time we see her, she is at her school watching SpongeBob dance around and says "I'm not ready..."
  • Evil Cripple: In "Demolition Doofus", Mrs. Puff loses her ability to puff and develops the desire to kill SpongeBob.
  • Failure Is the Only Option: No matter how many times she tries to get rid of SpongeBob (or get him in trouble legally), SpongeBob will always come out on top, leaving her stuck with him, or at worst, end up in jail.
  • Fat and Proud: Her size is a trait of her species, so she's not insecure about it.
  • Hair of Gold, Heart of Gold: Mrs. Puff has blonde hair and is rather kind-hearted, so long as your name isn't SpongeBob.
  • Half-Dressed Cartoon Animal: A rare female example. She doesn't wear any pants.
  • He Who Fights Monsters: Compared to the already hostile and mean-tempered Squidward, Mrs. Puff is a docile and well-meaning character whose nerves have slowly been worn at by SpongeBob's behavior. Many episodes have shown her take increasingly desperate and sometimes unscrupulous measures just to finally get away from him. She's at her lowest point in "Demolition Doofus", where she's so furious at SpongeBob for accidentally puncturing her inflation sac that she outright tries to murder him.
  • Heavy Voice: In her earliest appearances, she gets a deeper voice whenever she puffs up.
  • Idiot Ball: Despite being one of the few characters on the show with any common sense (aside from Squidward and Sandy), she holds this in "The Bully" when she fails to take action against an obvious bully who has joined her class and plans to harm one of her students, instead viewing him as a nice guy.
  • Intergenerational Friendship: With Sandy and Pearl in a few episodes, and also with SpongeBob in very early episodes, since she's considerably older than them.
  • Interspecies Romance: Her relationship with Mr. Krabs qualifies, since she's a blowfish and he's a crab.
  • It's All My Fault: In early episodes, she thinks SpongeBob's inability to drive is at least partially her fault.
  • Jerkass Ball: She's usually always hostile toward SpongeBob, but sometimes her grudge against him can go way too far, such as when she threatened to kick his butt at the end of "The Bully" over something he didn't do, and of course, going as far as trying to get him murdered in "Demolition Doofus". It's aggravated by the fact that she's supposed to be an authority figure.
  • Jerkass to One: SpongeBob is typically the only person whom Mrs. Puff holds a grudge against. Aside from him, she's usually outgoing and friendly to everyone. Plus, it isn't hard to see why she's hostile toward him, considering the amount of times he has endangered her with his reckless driving and gotten her arrested.
  • Knight of Cerebus: She briefly becomes one in the Season 8 episode "Demolition Doofus". She enters SpongeBob into a demolition derby and hopes that he dies (since his crazy driving previously caused her to puncture her inflation sac). She later tries to kill him herself by entering into the demolition derby using a massive monster truck. This episode is considered one of the darkest stories by many fans.
  • Made of Iron: Spongebob has caused this poor woman to get injured many times in fatal car crashes, but she seems to return to normal in a few episodes. It's only on "Demolition Doofus" that this trope was subverted with her losing her ability to puff and played straight at the end of the episode when she regains her ability to puff.
  • Meaningful Name: Her name refers to both her species and her tendency to puff up like a ball.
  • Misplaced Retribution: She is always blamed and put in jail for SpongeBob's recklessness despite educating him right, with SpongeBob going completely scot-free every time.
  • Naked People Are Funny: "Feral Friends" has her and Pearl become the first female characters shown naked on the show in the series' history. When she and Mr. Krabs return to normal two hours after being transformed into non-anthropomorphic sea life by Neptune's Moon, they bashfully giggle at seeing each other nude and promptly run off in embarrassment.
  • Nervous Wreck: She's very neurotic, although it's usually justified.
  • Never Bareheaded: Whenever she's not seen wearing her trademark sailor's cap, she usually wears hair curlers to bed.
  • Never Mess with Granny: She is around Mr. Krabs' age (early 70s) but has a dark side and commits many crimes.
  • Never My Fault: True, SpongeBob is the reason why she's so grouchy and getting constantly injured, but she forgets the fact that she's not obligated to keep SpongeBob as a student and she can simply expel him if she's tired of him failing her classes. While her suffering isn't her fault, she is unintentionally playing a role in prolonging it due to her never thinking of expelling [SpongeBob] from her boating school. It also helps that she mentioned that SpongeBob was the only student who has ever failed her boating school.
  • Nice Girl: Mrs. Puff seems friendly to everybody. It's only SpongeBob who she can't seem to stand.
  • Nice Hat: Almost always wears a blue sailor cap.
  • No Accounting for Taste: Is in a committed 16-year relationship with Mr. Krabs.
  • Non-Giving-Up School Guy: She is relentlessly determined to continue teaching SpongeBob.
  • Non-Mammalian Hair: She's a fish who has short blonde hair.
  • Not So Different: From Squidward. They both agree that SpongeBob is the bane of their existences.
  • Obsessed with Food: She loves pasta, chocolate cake, and Krabby Patties. Her love of food seemed to be a running gag in early episodes.
  • Official Couple: With Mr. Krabs. As of "Whirly Brains," they have been dating for sixteen years in canon. However, this is shockingly debunked in prior episodes (e.g. "Growth Spout", "Summer Job"), where she doesn't even seen to recognize him. This being SpongeBob, continuity errors are natural, and their relationship seems to be consistent from the former episode onwards, courtesy of the series becoming more continuity-driven.
  • Older Than They Look: Like Mr. Krabs, she looks a bit younger than her true age, although she does have wrinkles on her face in up-close shots.
  • Out-of-Character Moment: In the infamous "Demolition Doofus", she is driven insane after one of SpongeBob's accidents causes her to deflate. She actually tries to get SpongeBob killed in a demolition derby. Thankfully, she was turned back to normal at the end.
  • Only One Name: She is only ever called "Mrs. Puff" in the series proper. Merchandise such as books and the video game Yellow Avenger state that her first name is Poppy.
  • Only Sane Woman: She often fills the role of being the only reasonable person when an episode only stars her and SpongeBob.
  • Parental Substitute: She tries her best to be motherly with SpongeBob.
  • Person as Verb: "Puff" has been used as an adjective by other characters when talking about her. It's not very clear whether or not it's referring to her name, the actual verb, or both.
  • Principles Zealot: Mrs. Puff refuses to go against her principles regarding her Boating School, despite the fact that she gets hospitalized for having to put up with SpongeBob's bad driving. She could either make an exception to her principles and just expel him.
  • Rage Breaking Point: SpongeBob possibly deflating her permanently in Demolition Doofus seemed to be this, with her somewhat calming down at the end when she was able to puff again.
  • Running Gag: Many episodes ended with her going to jail.
  • Sanity Slippage: She tends to go crazy from having to deal with SpongeBob's antics.
  • Slapstick Knows No Gender: She is always a victim of SpongeBob's recklessness.
  • Species Surname: Her name is Mrs. Puff and she's a puffer-fish.
  • Spell My Name with an "S": She is often mistakenly called Ms. Puff by casual fans. Oddly, she has also been called "Mrs. Pearl" by more than a few.
  • Stepford Smiler: It is implied on several occasions that her cheerfulness is just a facade to mask the pain she feels over having to deal with SpongeBob all the time.
  • Temporarily a Villain: In "No Free Rides" and "Demolition Doofus", she acts as an antagonist toward SpongeBob out of being sick of having to put up with him.
  • Tertiary Sexual Characteristics: She has visible eyelashes to certify her gender.
  • Throwing Off the Disability: In "Demolition Doofus", she ruptures her inflation sac, with the doctor stating she'll never be able to puff again. Since Status Quo Is God, Mrs. Puff spontaneously regains her ability to puff at the end of the episode.

    Pearl Krabs 

Pearl Krabs

https://static.tvtropes.org/pmwiki/pub/images/spongebob_pearl.jpg
"As far as disasters go, that was really fun."
English voice: Lori Alan
Latin American Spanish voice: Irina Índigo, Yensi Rivero, Sofía Narváez
German voice: Sabine Winterfeldt
Debut: "Squeaky Boots"

Mr. Krabs' beloved teenage daughter, who is a huge sperm whale. Her brain is the largest in Bikini Bottom and she is gifted in math, but she is still young and immature. Her father hopes to pass his restaurant on to her when she grows up.


  • Acrofatic: Justified. She's a whale, so of course she'd be agile for her size.
  • All Girls Like Ponies: In "Whale of a Birthday", Pearl spots a mini seahorse at the mall and expresses immense affection towards it.
  • Ambiguously Related: Her biological relationship to her father isn't mentioned. It's unknown if she's adopted or whether she takes after her Missing Mom.
  • And Call Him "George"!: Being a Genki Girl, she has a lethally affectionate attitude.
  • All of the Other Reindeer: Depending on the Writer, she tends to have a reputation among her peers as the social outcast.
  • Animals Not to Scale: She is a whale who's only twice the size of miniature creatures like starfish and crabs. Some international dubs justify this by claiming she is a baby whale, but she is 16 (mentally, at least).
  • Bratty Teenage Daughter: On a frequent basis, she berates Mr. Krabs and whines whenever he doesn't let her have what she wants.
  • Butt-Monkey: She is often mistreated, neglected, and publicly embarrassed by her cheapskate asshole of a father, belittled and betrayed by her friends, and has suffered many breakups. On a side note, her height often makes her subject to klutziness.
  • Can't Get in Trouble for Nuthin': In "Bossy Boots", she goes to work for the Krusty Krab during her summer vacation, and makes multiple changes to the restaurant that effectively ruin her father's business. As it turns out, all the changes she made were because she was deliberately trying to get fired, but Krabs simply didn't have the heart to fire his own daughter. So SpongeBob, who was sent to fire her anyway, "pretends" to fire her so she could go and enjoy her summer vacation.
  • The Cheerleader: She regularly wears her cheerleading uniform even outside of school and is shown to be one in "Culture Shock", where it's the subject of her performance at the Krusty Krab talent show. When taking into account her height however, the results are drastic.
  • Cool Big Sis: She's had more than a few mutually affectionate moments with SpongeBob and often plays the role as a sister figure to him, due to her being a typical teenage girl and him being a naïve and innocent manchild.
  • Cute Clumsy Girl: She's quite the Genki Girl and qualifies as clumsy owing to her gigantic height.
  • Daddy's Girl: Her default status is Mr. Krabs' beloved teenage daughter whom he often babies in an attempt to discourage her conformity to toxic stereotypes. She's becoming less true to this status as the series progresses, however, partly due to her father's overprotective and cheap nature.
  • Damsel in Distress: In "Dunces and Dragons", where Planktonamor kidnaps her and SpongeBob and Patrick have to rescue her.
  • A Day in the Limelight:
    • While all of the prominent characters have times to shine every once in a while, "Mall Girl Pearl" is the only episode in which SpongeBob has no plot relevance whatsoever and plays no direct role in the outcome of the story. The episode exclusively focuses on Pearl as she tries to get a job at the mall, with SpongeBob appearing in two background cameos stalking Squidward and one more cameo at the end when he retrieves Beatrice's dropped hand. The last cameo is meant to reference how he wasn't part of the episode.
    • "Whale Watching" centers on both Pearl and Squidward. On the night that Mr. Krabs likes to play poker, he hires Squidward, whom Krabs promised a SpongeBob-free shift, to look after Pearl, who was forbidden from going out that night to hang out with some kids, including a boy she had a crush on. Pearl manages to sneak out, and Squidward follows to where she beaches herself after she breached the surface. Seeing her in trouble, the other kids run away, leaving Squidward to rescue her. After they get home, they decide to have some fun by siccing SpongeBob on the boy that left Pearl beached on the surface.
  • Depending on the Writer:
    • In the first three seasons, she and SpongeBob have a very close bond. Some post-movie episodes disregard all of their previous interactions and don't portray Pearl as a friend to him. Of course, SpongeBob is always extremely nice to Pearl, regardless of the season. Despite his undying loyalty to Mr. Krabs, he is even friendlier to Pearl than he is to his boss. This is shown in episodes like "Whale of a Birthday" and "Barnacle Face" where SpongeBob takes Mr. Krabs' belongings to make Pearl happy.
    • Her reputation. She ranges from being an Alpha Bitch in a Girl Posse to The Friend Nobody Likes. Due to the lack of recurring characters and continuity in general, she's also depicted with different friends per appearance.
    • Her relationship with her father. She ranges from genuinely loving him and being on good terms, being displeased with him but still caring about him deep-down, or outright despising him and overpowering his authority. Since she's a stereotypical teenage girl, the variety isn't surprising. It also sort of depends on her father's part.
  • Drama Queen: Pearl loves to cry over insignificant slights and is quite possibly the show's biggest drama magnet. Although, unlike SpongeBob, who exhibits meltdowns over the most mundane of things like running out of ice, Pearl's angsts are reasonable given her age range.
  • The Dreaded Pretend Tea Party: When SpongeBob enters her dream in "Sleepy Time" and sees that she's having a fake tea party, he asks her how to get to Mr. Krabs' dream instead.
  • Fangirl: She is a huge fan of "Mecha Baleen" and "The Adventures of Mermaid Man and Barnacle Boy", according to the comic series and the SpongeBob Moves In! app respectively. She's also a huge fan of the boyband Boys Who Cry, whom she wanted so bad to perform at her 16th birthday party (they did).
  • Flanderization: Her brattiness, bad luck, and disrespect for her father got worse by the post-movie seasons.
  • Freudian Excuse: With the way Mr. Krabs treats her, you can understand her attitude.
  • Gender Equals Breed: Her father is a crab and her mother was (presumably) a whale.
  • Genki Girl: Pearl is quite cheerful. She constantly shouts and eagerly bounces up and down when confronting Mr. Krabs about something she wants, for starters. The fact that she's a cheerleader tops it all off.
  • Girly Girl: She wears a pink dress, is a huge fan of boy bands (especially Boys Who Cry), gossips a lot, likes hanging out at the mall with her girlfriends, and in general possesses a lot stereotypical Valley Girl and Phoneaholic Teenager traits.
  • Give Geeks a Chance: In "The Chaperone", her boyfriend was a nerdy little baitfish...although she describes him as incredibly "long, tan, and handsome".
  • Girls Love Stuffed Animals: In "Sleepy Time", she dreams about a tea party with stuffed animals.
  • Gonky Femme: She is a huge girl with inhuman strength and a tendency to cause everything to shake whenever she is crying, jumping or dancing.
  • Gossipy Hens: She gossips quite a lot with her friends.
  • Hidden Depths: Her original character bio reveals that she has the biggest brain in Bikini Bottom and loves math.
  • Hilariously Abusive Childhood: Most of the neglect she receives from her cheapskate father is played for comedic effect.
  • Huge Schoolgirl: Considering she's a whale among little animals like fish and squirrels.
  • Hypocrite: She singles Mr. Krabs out for babying her in "Goodbye, Krabby Patty?" when directing the commercial for Frozen Krabby Patties, but she has frequently addressed him as "Daddy", a trait typically associated with younger children.
  • I Got Bigger: The entire plot of "Growth Spurt" revolves around Pearl undergoing a growth spurt that not only causes her to outgrow her bed, but also endlessly demand food to fulfill her metabolic hunger. She regresses to her regular size by the end after she eats a Krabby Patty.
  • I Just Want to Be Special: There's often the implication that Pearl only behaves like an average teenage girl in a desperate attempt to fit in with the crowd.
  • Implied Love Interest: Quite a few episodes frame Pearl as this for SpongeBob, in ways that are sometimes more blatant than any Spandy moments.
    • "The Chaperone" is all about Pearl taking SpongeBob to prom, and the end—where they hold hands and almost kiss until Mr. Krabs scares them—seals the deal.
    • "Bossy Boots" is a major moment as well, since Pearl hugs SpongeBob so hard he has to ask her to stop and later kisses him on the forehead.
    • In the post-movie episode "Tunnel of Glove", the plot involves Pearl and SpongeBob going in a tunnel of love at Glove World, and it starts off with Pearl's fake friends calling SpongeBob her boyfriend. Even though this episode was made after the writers started disregarding Pearl and SB's friendship, the ending implies that Pearl does like SpongeBob but pretends not to when her friends are around.
    • The solution to Pearl's growth spurt in "Growth Spout" is SpongeBob making her a special Krabby Patty with love.
  • Inferiority Superiority Complex: Many episodes focusing on her reputation portray her as a talentless hack who behaves like a rebellious teenage girl in a desperate attempt to fit in.
  • Informed Ability: According to her official character bio, she's the smartest citizen in Bikini Bottom, but there has never been an episode focusing on her intelligence. There have, however, been episodes like "Mall Girl Pearl" that imply she only acts like a regular teenager to fit in.
  • Intergenerational Friendship: With SpongeBob, who's an independent adult.
  • Ironic Name: Pearls are known for being very small, but Pearl is huge.
  • It's All About Me: Has this attitude in "Whale of a Birthday", even saying that everyone in the world has to pay attention to her on her birthday.
  • Jerkass Ball: She holds this in episodes that showcase her as an Alpha Bitch, specifically in the episode "The Slumber Party" when she and her friends make fun of a sponge girl who looks like SpongeBob.
  • Jerk with a Heart of Gold: While she tries her best to fit in with her bratty peers, Pearl's "hip, cool" persona is merely a ruse and she wants to be friends with SpongeBob. This is most obvious in the early episode "Bossy Boots", where she tearfully confides in SpongeBob that her new position is too stressful and that she only accepted it to make her father happy- and she thanks SpongeBob with a hug and a kiss when he helps her quit.
  • Kiddie Kid: Downplayed, as she acts and wants to be treated like a regular teenage girl more than anything, but she still has shades of this nonetheless, yet she'd never admit it to anyone. Mr. Krabs also views her as such.
    • She typically addresses her father as "Daddy" rather than just "Dad" like most older kids.
    • In "Sleepy Time", she has a dream of her throwing a tea party with stuffed animals.
    • She seems to have a fondness for sea-ponies, as seen in "Whale of a Birthday".
  • Large Ham: She has an overdramatic voice, which isn't surprising given her height.
  • Like Brother and Sister: She plays quite a sisterly role to SpongeBob whenever she's not outright hating him.
  • Likes Older Men: Like most girls her age, she fantasizes over men who are at least ten times her senior, if not in the same age range as her.
  • Lovable Alpha Bitch: Some episodes depict her as joining the Girl Posse to fit in and acting rather condescending to the less fortunate. When taking into account the unreasonable amount of neglect she receives at the hands of Mr. Krabs, she still remains sympathetic in that the very hand that feeds and shelters her is too cheap to satisfy her demands despite being rich.
  • Missing Mom: Her mother has never been revealed nor mentioned in the show. Word of God is that they're against revealing her identity and strive to keep it a secret throughout the show's run.
  • Naked People Are Funny: "Feral Friends" has her and Mrs. Puff become the first female characters shown naked on the show in the series' history. After everyone returns to normal two hours after being turned into non-anthropomorphic sea creatures by Neptune's Moon, she is shocked to find herself naked in public and runs away in embarrassment while covering herself.
  • No Indoor Voice: All the time, but it's especially emphasized when Mr. Krabs riles her up.
  • Non-Standard Character Design: She's the only one with monocular vision: eyes on the sides of her head rather than in front.
  • Not Allowed to Grow Up: She's been sixteen years old for decades. Funnily enough, episodes like "Goodbye, Krabby Patty?" and "Whirly Brains" make direct references to how many years have passed since the show started out. Pearl is the only character with a definite age, and it's stayed the same throughout all of these episodes, causing some continuity errors.
  • Ocular Gushers: Due to her enormous height, she cries large puddles of tears, even flooding the Krusty Krab with them at one point.
  • Odd Friendship: Played With in regards to SpongeBob. While their relationship makes sense in context in that the latter is her father's employee, SpongeBob has been identified as an adult numerous times yet has the demeanor of a child, while Pearl is a stereotypical teenage girl.
  • Parental Title Characterization: She's an affectionate, but somewhat bratty, Daddy's Girl of a teenager. As a result, she still calls her dad "Daddy".
  • Phoneaholic Teenager: She is frequently seen talking on her cellphone.
  • Pink Means Feminine: Her standard outfit is a pink and purple dress.
  • Teens Love Shopping: Pearl and her girlfriends like to shop at the mall.
  • Tomboy and Girly Girl: The Girly Bratty Teenage Daughter to Sandy's karate chopping techno whiz Tomboy.
  • Took a Level in Jerkass: She becomes more spoiled and rude in later episodes.
  • Valley Girl: Borderline case of a girl who cares more about being stylish than anything else.

    Gary the Snail 

Gerald Wilson Jr.

https://static.tvtropes.org/pmwiki/pub/images/spongebob_gary.jpg
"Meow."
English voice: Tom Kenny, Keith David (translator voice in "Chatterbox Gary")
Latin American Spanish voice: José Manuel Vieira, Fernando Márquez
German voice: Santiago Ziesmer
Debut: "Help Wanted"

SpongeBob's pet snail, who meows like a cat.


  • Affectionate Nickname: He calls SpongeBob "PapaBob" in "Chatterbox Gary" when he gets a translator for his meows. SpongeBob also calls him "Gare Bear" quite often.
  • Animal Jingoism: In "Pets or Pests", he develops a mutual hatred for a worm SpongeBob takes in, since worms in this show are the undersea equivalent of dogs.
  • Ascended Extra: In the earlier episodes, he was just a Satellite Character to SpongeBob, before his role gradually increased and allowed him to develop a personality.
  • Berserk Button: Do NOT check his undercarriage. You'll be lucky if he just gives you a warning by hissing at you.
  • Big Eater: He eats the entire year supply of snail food SpongeBob left for him in "What Ever Happened to SpongeBob?" as well as a lot of cookies in "Have You Seen This Snail?"
  • Butt-Monkey: He's abused mercilessly in a few episodes of the later seasons like "A Pal For Gary", "The Cent of Money" and "Pet Sitter Pat".
  • Cats Are Mean: Under the show's theory of snails existing as an underwater equivalent for cats. Subverted for the most part, though he has his occasional Jerkass moments like most of the cast: "Dumped" shows he can be a rather fickle bastard.
  • Cats Hate Water: Being the equivalent thereof, he's not a fan, even though technically he lives underwater.
  • Character Development: Started off as a gag character whose sole purpose was to exhibit snails as an underwater equivalent to cats. Although his vocabulary is still limited to "meow", he arguably has much more of a personality nowadays than he did in the earlier seasons.
  • Connected All Along: "Rule of Dumb" reveals he and Patrick are cousins.
  • Does Not Like Spam: The Sponge Bob Movie Sponge Out Of Water reveals that he hates mayonnaise.
  • Furry Confusion: Averted. There are no sapient snails on this show, so there's no issue in him being a pet coexisting with anthropomorphic sea life.
  • Hate at First Sight: Towards Squidward during their introduction together in "I Was A Teenage Gary." The feeling was mutual on Squidward’s behalf, since he’s allergic to snails and his initial reaction towards the former. Squidward not feeding him over the weekend probably didn't help...
  • Hates Baths: As seen in "Gary Takes a Bath" and "Pet Sitter Pat", he doesn't like taking baths. This phobia is based on how felines are opposed to water.
  • Hypercompetent Sidekick: He often seems smarter than his owner.
  • Intellectual Animal: In the episode "Sleepy Time", he is revealed to be quite intelligent through his dream self.
  • Intelligible Unintelligible: SpongeBob and some of the other characters can understand Gary even though he only meows.
    Mr. Krabs: SpongeBob, what's wrong with you?
    Gary: Meow!
    Mr. Krabs: The Suds?!
  • Jerkass Ball: In "Dumped", where he decides to stay with Patrick (who himself also grasps the Jerkass Ball in this episode) despite SpongeBob blatantly showing his depression over being separated from him. Subverted however, as he only interested in the cookie in Patrick's pocket.
  • Jerk with a Heart of Gold: Gary comes across as gluttonous and can be occasionally selfish and uninterested in some of the things SpongeBob wants to do. However, he is a very gentle snail who loves SpongeBob very dearly.
  • Killer Rabbit: He's mostly a sweet snail, but he has his dark side; he rebels and leads a revolution with other snails and worms against a pet show in "Grooming Gary" due to SpongeBob abusing him just to score a win, and admits through a translator that he fantasizes about raining fiery vengeance down on those who've wronged him in "Chatterbox Gary".
  • Luke, I Am Your Father: "Rule of Dumb" reveals him and Patrick to be cousins.
  • Odd Name Out: His full name has nothing to do with his species, unlike most of the other characters.
  • Only Known by Their Nickname: He's never called by his real name, "Gerald".
  • Only Sane Man: Despite being a pet, Gary fills the role of the only reasonable and rational person the vast majority of the time.
  • Nearly Normal Animal: While he mostly functions as an ordinary pet, he does occasionally exhibit some human mannerisms or gestures, such as drinking from a glass, and he seems to think on a sapient level. His meows are intelligible to most who interact with him.
  • Ridiculously Cute Critter: He's a cute little snail.
  • Secret Test: In the episode "Treats!" Gary pesters SpongeBob to get him a box of discontinued treats, and spends the episode in vain searching for the snacks. When SpongeBob takes Patrick's advice, and tells Gary "no" they will not keep searching, Gary goes to bed happy to know that SpongeBob learned to say "no."
  • Silent Snarker: Often non-verbally expresses his disdain for his owner's idiocy.
  • Snarky Non-Human Sidekick: Despite all of them being sea creatures and all (except for some one-offs, Mermaid Man, and Barnacle Boy). Even if the audience will never be able to figure out what he's saying, SpongeBob's retorts to whatever he says show that he is rather snarky.
  • Token Good Teammate: One of the few characters who is not a Jerkass, an antagonist, or a moron (although he can be fickle at times).
  • Undying Loyalty:
    • If him rescuing SpongeBob from Puffy Fluffy after the sponge treated him like crap doesn't qualify for how unwilling he is to turn against SpongeBob, nothing does.
    • In "Suds", SpongeBob curtly dismisses Gary's insistence that he stay home from work. Despite this, Gary seemingly follows SpongeBob to work just to tell his boss that he's ill.
