Fictional Characters Wiki

SpongeBob SquarePants is the titular protagonist of the very popular Nicktoon of the same name. He is voiced by Tom Kenny and first appeared on television in the series' pilot episode, "Help Wanted", on May 1, 1999. SpongeBob SquarePants was created and designed by former marine science teacher Stephen Hillenburg, who originally used the character in an educational book he wrote in the 1980s. Thanks to success and popularity of the franchise, SpongeBob SquarePants has become a household name and the official mascot of Nickelodeon, and also appears in the current Nickelodeon Movies logo.

As shown in "The Secret Box", SpongeBob SquarePants has known his best friend Patrick since they were both little babies. SpongeBob SquarePants moved into his sunken pineapple house with his pet snail, Gary, one day after moving out of his parents' house. He later met his next-door neighbor, Squidward. His teacher is Mrs. Puff and his boss is Mr. Krabs.

SpongeBob SquarePants is an excitable and charming young sponge. He and Patrick Star often annoy Squidward Tentacles without really knowing it.

Physical Appearance[]

SpongeBob SquarePants is a sea sponge with a rectangular shape. He is light yellow (whose exact shade of yellow is designated by Pantone to be SpongeBob Yellow) with a light olive-green outline. In earlier episodes, he is wider near the top and gets skinnier going further down, akin to that of a trapezoid. However, in the more recent episodes, he is more of a regular square shape.

SpongeBob SquarePants has light olive-green pores, dimples with three freckles on each cheek, a large mouth with two prominent front buck teeth, a long, slightly curved nose, and large light blue eyes. His eye color seems to be, uniquely, a shade of pacific blue complimenting the blue ocean background. He has three exceptionally wide, exposed, and effeminate eyelashes on each eye, which have sometimes been shown to be numerous eyelashes akin to a human, which is best prominent in "Tutor Sauce" when he is seen breathing heavily during a close-up.


SpongeBob SquarePants is a fun-loving, hyperactive, clueless, and childish sea sponge with a happy-go-lucky personality. Despite being portrayed this way, he is relatively smart and knows right from wrong, an example being telling Patrick Star not to draw his picture of calling Mrs. Puff a "big, fat, meanie" because she's a teacher. He is extremely determined and will often stop at nothing to accomplish a task. He is also somewhat dramatic to the people who are kind to him: for example, to the mailfish. He is also over-confident. Sometimes, though, he shows his devious side when trying to get Eugene H. Krabs and Sheldon J. Plankton to work together. The Other Patty He sometimes makes mountains out of molehills, such as losing his name tag. It is also suggested that he deceived the Tattletale Strangler in an elaborate plot to get him back to jail. When he first met Plankton, he was almost quick to befriend him, but quickly realized Plankton's true intention was to take advantage of him to steal the Krabby Patty secret formula. Plankton himself is surprised that SpongeBob SquarePants was smart enough to see through his manipulation, telling him, "Gee, and I thought you were stupid".

SpongeBob SquarePants is very kind-hearted and innocent, and very rarely acts openly mean to anyone, even those who find him an annoyance and act cruelly to him. He is a very selfless and loyal person, especially towards those close to him. His selfless nature is most notably shown in "Best Day Ever," where he sacrifices his "perfect day" to help his friends. Despite his well-meaning intentions, SpongeBob's actions often annoy and cause trouble for those around him, most notably his next-door neighbor, Squidward Tentacles.

SpongeBob SquarePants can become scared easily and usually panics when frightened. He is afraid of the dark and clowns. He also hates hot sauce. Occasionally, SpongeBob SquarePants is too ignorant to notice impending danger and his unworldly thinking may put himself or others in peril. He also cannot detect lies or malice as easily as the other characters, mainly due to his naïvety. This is particularly evident in episodes featuring Squidward Tentacles, such as "Giant Squidward", "Good Neighbors", "Squid's Visit," and "Tentacle-Vision". In these episodes, as well as many others, SpongeBob SquarePants believes he is making Squidward Tentacles happy, even though he's actually making him miserable. One non-Squidward example is in "A Pal for Gary," when Gary is being violently attacked and nearly eaten by Puffy Fluffy, SpongeBob SquarePants takes no action and instead accuses Gary of harassing Puffy. Another example is "Home Sweet Rubble," when it takes SpongeBob SquarePants a few moments to realize that his house is in serious need or repair.

Furthermore, SpongeBob SquarePants also goes to great lengths to impress others and achieve his goals, even if they involve malice, as seen in "Mermaid Man and Barnacle Boy II," where SpongeBob SquarePants wrongly attacks an innocent Atomic Flounder to impress Mermaid Man and Barnacle Boy. SpongeBob SquarePants attempts to steal Patrick Star's secret box in "The Secret Box." He also tries to steal Betsy Krabs' underwear along with Patrick Star and Eugene H. Krabs in "Mid-Life Crustacean" as part of the "panty raid." In "Doing Time," SpongeBob SquarePants and Patrick Star force the receptionist of the local bank to give them all his money; this was done in an attempt to get arrested and free Mrs. Puff from jail. In "Hall Monitor," SpongeBob SquarePants enters the window of a couple's house and disturbs them while on hall monitor duties; this was done to show them the consequences of leaving a window open. In "The Great Snail Race," SpongeBob SquarePants overexerts Gary to prepare him for the following snail race. This causes extreme discomfort to Gary and eventually results in him collapsing on his way to the finish line; however, SpongeBob SquarePants eventually noticed the error in his ways.

In "Employee of the Month," SpongeBob SquarePants sets up many traps on Squidward Tentacles in an attempt to sabotage his Employee of the Month Award. In "Just One Bite," SpongeBob SquarePants handcuffs himself to Squidward Tentacles, forcing him to eat a Krabby Patty. In "Shuffleboarding," he and Patrick Star, while dressed as Mermaid Man and Barnacle Boy respectively, go around arresting citizens for actions that do not count as crimes, such as chewing gum too loudly and being too old. In "SpongeBob's Last Stand," SpongeBob SquarePants and Patrick Star resist the government-sanctioned construction of the Shelly Superhighway and encourage the rest of the town to join their protest through a song. The police eventually notice the boys rebelling against the government's authority and imprison them in the middle of nowhere. However, on SpongeBob's part, his arrest was for playing the sitar without a license.

SpongeBob SquarePants also feels the need to impress Mr. Krabs and to protect the Krusty Krab and the Krabby Patty secret formula at all costs. In "Call the Cops," SpongeBob SquarePants and Mr. Krabs impersonate police officers in hopes of retrieving the secret formula. He also likes to impress his boating teacher, Mrs. Puff, despite his reckless driving. Beginning with "Boating School," an ongoing plot point is SpongeBob SquarePants failing his driver's test due to his inability to drive safely. His poor driving skills have caused him to run over pedestrians, rapidly switch lanes, drive on the sidewalk, crash into buildings and property, harm his passengers, and lastly damage his vehicle. Despite all the damage he causes, SpongeBob SquarePants is never arrested or charged for his dangerous driving; instead, Mrs. Puff is, who the authorities believe is failing to educate him.

These actions can often lead to SpongeBob SquarePants entering by trespassing. SpongeBob SquarePants and Patrick Star have a frequent tendency to enter Squidward's house without his consent, which reaches its epitome in "Good Neighbors" and becomes a plot point of the said episode. Additionally, in "Survival of the Idiots," SpongeBob SquarePants and Patrick Star invade Sandy's treedome during the winter with little regard to the "Keep Out" sign on her door. In "The Thing," after getting caught by the SWAT Team, SpongeBob SquarePants and Patrick Star hide from them by trespassing into the sewers. SpongeBob SquarePants also invades the sewers with Squidward Tentacles in "The Sewers of Bikini Bottom", although they did it to retrieve the safe, so this can be justified. In "Toy Store of Doom," SpongeBob SquarePants and Patrick Star stay in Toy Barrel past its open hours and hide in a dollhouse so as not to be caught by the security guard.

SpongeBob SquarePants' personality trait of wanting to impress others and achieve his goals has to lead to him having a history. However, due to his naïvety and gullibility, a lot of these crimes have been committed unintentionally or through the manipulation of others, mainly Squidward Tentacles, Plankton, Karen Plankton, or Mr. Krabs. He has been arrested a total of seven times: for "stealing" a balloon in "Life of Crime," failing to invite the police to his party in "Party Pooper Pants," littering Patrick Star's driver's license in "Driven to Tears," playing sitar without a license in "SpongeBob's Last Stand," falsely accused public disturbance in "Cave Dwelling Sponge," impersonating a police officer in "Call the Cops," and unintentionally terrorizing a majority of Bubbletown in the episode of the same name.

SpongeBob SquarePants' innocence also makes him overly trusting and very gullible, easily manipulated by people who intend to use and/or harm him, such as Squidward Tentacles, Mr. Krabs, and Plankton, and he is clumsy. In "Walking Small," SpongeBob SquarePants assists Plankton in driving the attendants at Goo Lagoon away to make an unauthorized development to its property. However, this was done out of manipulation, and SpongeBob SquarePants regrets his actions after learning Plankton's motive, therefore returning the beach to its previous state. In "Sandy's Rocket," SpongeBob SquarePants and Patrick Star go around capturing everyone in Bikini Bottom and trapping them in the spaceship, believing that the entire population is formed of aliens.

Even though he is generally good-natured and easygoing, SpongeBob SquarePants can get angered easily. When frustrated and angered, SpongeBob SquarePants can be sarcastic, rude, and condescending to his friends, even Mr. Krabs, whom he treats as a father figure. Squidward Tentacles is the only character whom SpongeBob SquarePants never insults when he is angry, except for the episodes "Can You Spare a Dime?" and "Breath of Fresh Squidward."

In "Hooky," SpongeBob SquarePants is encouraged by Patrick Star to ditch work during his shift, which causes the unsupervised grill to produce mass amounts of smoke. He believed King Neptune's trident was his spatula and decided to help all of Bikini Bottom when he was destroying the town after going mad with power in "Trident Trouble." In "Hall Monitor," SpongeBob SquarePants lets his rank of hall monitor go to his head and becomes known as the maniac for his destruction of the city before receiving a scolding from his teacher who was arrested for it. During "Ditchin'," SpongeBob SquarePants ditches boating school to attend the Mermaid Man and Barnacle Boy meet and greet, which affects his driver's education and eventually gets Mrs. Puff arrested. Even stated in "Goons on the Moon" that he is a menace despite his good nature.

Despite his overall kindness, SpongeBob SquarePants occasionally shows a lack of empathy for others and forces people into situations against their will. In the episode "Rodeo Daze," he kidnaps the Bikini Bottomites with bubbles in persuasion for them to save sandy from a rodeo. Additionally, in the episode "A SquarePants Family Vacation," he sends his friends letters promising that everything they love will be at his house, only for it to be a hoax and a plea for them to view his slideshow.

Although SpongeBob SquarePants has several friends, and many of the citizens of Bikini Bottom often treat him quite friendly, most, if not all, citizens of the city have been shown to have some degree of dislike for him. In the episode "Gone," it is shown that a holiday called "National No SpongeBob Day" has been started by the citizens of Bikini Bottom. As its name suggests, it is an entire day dedicated to getting away from SpongeBob SquarePants, where the people leave Bikini Bottom for the day. Even Patrick Star goes, stating that everyone needs at least one day away from SpongeBob's laughter. In the ceremony, they build a giant wooden effigy of SpongeBob SquarePants, burn it down, dance on the ashes, and depart Bikini Bottom. SpongeBob SquarePants is more honored than insulted by this, as he was the "inspiration" for the holiday.

Abilities and talents[]

SpongeBob SquarePants has been shown to have numerous extraordinary abilities and attributes throughout the series.

  • Absorbency: Being a sponge, SpongeBob SquarePants is also absorbent, and can expand his body by absorbing liquids. Sometimes when SpongeBob SquarePants cries, he re-absorbs his tears. An example is in "The Bully" when Flats the Flounder kept on hitting him, but SpongeBob SquarePants just absorbed all of his blows. Also, in "I Had an Accident," he filter feeds through his holes, as he is a sponge.
  • Boneless: SpongeBob SquarePants is usually shown to be boneless since sea sponges are invertebrates. However, in some episodes, such as "I Had an Accident," bones are shown on his X-rays. He also has bones when his skin is ripped off in "Atlantis SquarePantis" and "The Splinter." He can also squeeze through and fit in things.
  • Bubble blowing: SpongeBob SquarePants can perform extraordinary moves with bubbles, most notably exhibited in "Bubblestand." It is considered along with jellyfishing as his and Patrick's favorite hobby.
  • Destruction: SpongeBob SquarePants has a degree of talent in destruction, but most of the cases show that he mostly performed this involuntary due to his gullible and reckless personality, Although he does not know it and thanks to his poor driving skills, SpongeBob SquarePants is skilled at demolition derbies. This is shown in "Demolition Doofus," as SpongeBob SquarePants manages to defeat five other competitors, although inadvertently, also surviving Mrs. Puff's murderous attack.
  • Culinary Creativity: SpongeBob SquarePants has made variations of Krabby Patty, even disgusting ones: "The Nasty Patty," "Secret Patty," "The Nature Patty," "Double Krabby Patty With Everything," "Crying Johnny," "Double Triple Bossy Deluxe Patty," "Krabby Patty Pizza," "Krabby Patty with Jellyfish Jelly"... just to name a few.
  • Driving (anything but a boatmobile): SpongeBob SquarePants can drive certain objects perfectly, but his nerves get the best of him when driving boats at Mrs. Puff's Boating School. On several occasions, he has been able to conquer his nervousness and demonstrate good driving skills, but he always loses this confidence by the end of the episode.
  • Fry cooking: SpongeBob SquarePants has a job cooking Krabby Patties at the Krusty Krab.
  • Jellyfishing: SpongeBob SquarePants and Patrick Star jellyfish at Jellyfish Fields in several episodes. In "Jellyfish Hunter," he catches every single jellyfish in the fields.
  • Karate: SpongeBob SquarePants trains for karate with Sandy and, in "Karate Choppers," is seen to be quite evenly matched with her.
  • Limb range: Like most characters in this series, SpongeBob SquarePants can stretch his body to unusual extents.
  • Regeneration: It is shown that SpongeBob SquarePants can quickly regenerate parts of his body that are injured or removed as this is natural for real sponges. He can also clone himself and reproduce by budding, most notably in "Pressure."
  • Enhanced reflexes: SpongeBob SquarePants possesses faster-than-lightning reflexes, being able to react to dangers instantly. Hence, SpongeBob SquarePants can dodge and react to projectiles and enemy attacks moving at high speeds, such as lasers, arrows, shock waves, bullets, and even lightning. Additionally, SpongeBob's sharp reflexes allow him to react to attacks outside his field of vision.
  • Stamina and endurance: In games such as Battle for Bikini Bottom, Nicktoons Unite!, Plankton's Robotic Revenge, etc., SpongeBob SquarePants has demonstrated very high stamina, capable of exerting himself to his peak performance for several hours without signs of fatigue. SpongeBob SquarePants is extremely durable, having survived life-threatening situations multiple times most likely due to his soft and flexible body figure. He has survived multiple traffic collisions, getting caught in the crossfire from all angles from Plankton's Robots, withstand the force of a building collapse, and being struck by opponents with super strength. Additionally, SpongeBob has more than once survived impacts from falls from extreme heights, withstand the force of a nuclear explosion (like how Plankton did once), and being struck by fire, electricity, and frozen by ice.
  • Super speed: As the Quickster, he can move very fast. Although he is certainly able to run faster than Patrick Star when he's about to tell Eugene H. Krabs in "Sailor Mouth" and Squidward Tentacles when he's about to chase SpongeBob SquarePants about the pizza in "Pizza Delivery."
  • Leadership: SpongeBob SquarePants is a great natural leader for all of his friends in Bikini Bottom.
  • Teleportation: SpongeBob SquarePants is capable of teleporting in various episodes. Like in "The Wreck of the Mauna Loa" when he is chasing Patrick Star in a game of tag, Patrick Star is looking back at SpongeBob SquarePants in the other direction, when he imminently bumps into SpongeBob SquarePants in front of him and in "Born to Be Wild" he was able to teleport to the Krusty Krab by riding on a bubble.
  • Ghost physiology: After he and Patrick accidentally shave the Flying Dutchman's beard, the powerful ghost curses SpongeBob SquarePants and Patrick Star by stripping them from their flesh and blood, turning them into ghosts. This gives them various ghost powers including intangibility, flight, ectoplasm creation, and turning inanimate objects into the said object's ghost version (SpongeBob SquarePants creates a ghost version of his spatula by breaking the original one, in which ghost version of the said spatula materializes from its remains). Eventually, the Flying Dutchman has to restore SpongeBob SquarePants and Patrick Star to normal due to their newfound cursed powers proving too much for them to handle (SpongeBob SquarePants can't interact with the realm of the living as he normally would and accidentally passes through the earth's crust while sleeping).
  • Sneaking: SpongeBob SquarePants can be very sneaky, as seen in "Employee of the Month."
  • Levitation: SpongeBob SquarePants can levitate infinitely.
  • Climbing: SpongeBob SquarePants can climb, as seen in "Party Pooper Pants" where he climbed on his house.
  • Singing and nose-playing: SpongeBob is shown to possess a fantastic singing voice. He uses his nose as a flute, in which he is very talented. He is also the lead singer in "Band Geeks." Later, he uses his nose flute in "Best Day Ever" to drive away from the nematodes from the Krusty Krab. His nose flute is notably played as a closing note of the SpongeBob SquarePants theme song.
  • Whistling: He can whistle due to his gap in his buck teeth. This ability is put on display in "Mind the Gap."
  • Comedy: SpongeBob can do comedy as telling jokes. This is seen well in "Squirrel Jokes."
  • Ventriloquism: SpongeBob can play around with Mini Squidward in the episode "Squid Wood."
  • Magic tricks: SpongeBob SquarePants is talented at magic tricks in "One Trick Sponge."
  • Ice skating: SpongeBob can ice skate. This ability is put on display in "Shanghaied" and "Krabs à la Mode."
  • Roller skating: He has shown that he can roller skate as seen in "Things to Do When Encountering a Legendary Creature" and "Sportz?"
  • Dancing: SpongeBob SquarePants has shown that he can dance. This ability is put on display in "Cave Dwelling Sponge."
  • Ukulele playing: SpongeBob SquarePants is very good at playing his ukulele.
  • Guitar playing: SpongeBob SquarePants would play guitar in a few episodes. He owns both acoustic and electric guitars.
  • Soft pliable body: Due to his soft, pliable frame, he is capable of shape-shifting, has some degree of invulnerability, being able to absorb many types of physical impact, shown most notably in the episode "The Bully."
  • Body part changing: SpongeBob SquarePants can change his body parts into objects as well as shapeshifting.
  • Multiplying body parts: He can multiply his body parts due to his regeneration.
  • Multitasking: To a certain degree, but it is especially true when he cooks. He can pump out the entire restaurant full of diners with Krabby Patties. He is not so well at it when driving as he gets distracted.
  • Cloning: He can clone minions of himself by slicing his skin into layers.
  • Multilingual: In the episode "Sold!," SpongeBob SquarePants is shown to be able to speak fluent German.
  • Mimicking: He can mimic someone else by shapeshifting. In "Mimic Madness," he mimics his friends.
  • Survival skills: In "To Save a Squirrel," SpongeBob SquarePants and Patrick Star almost eat each other to survive. Eventually, they are saved by Sandy and no longer had to resort to the desperate measure.
  • Water breathing: Being a sea creature means he can breath underwater.
  • Reef blower (machine): SpongeBob can use a reef blower to suck or blow things, like when he sucked up all the water in Bikini Bottom in "Reef Blower."
  • Tongue-boarding: SpongeBob SquarePants tongue-boards in "Prehibernation Week," as well in the video games Battle for Bikini Bottom, The SpongeBob SquarePants Movie (video game), SpongeBob's Truth or Square, Nicktoons: Attack of the Toybots, SpongeBob SquarePants featuring Nicktoons: Globs of Doom and Battle for Bikini Bottom: Rehydrated and the book Tales from Bikini Bottom.
  • Magic Pencil: The pencil grants the user god-like abilities. The user can create anything and erase anything at will.


  • Lack of physical strength: Due to his physiology, SpongeBob's natural physical strength appears to be below average. Even one instance exaggerated this whereupon close inspection, his hand was depicted in the emaciated state as if it was only skin and bone. Although, SpongeBob can sometimes build up strengths he normally isn't capable of possessing by sheer force of will, with his prowess dependent on the writers of the episode.
  • Fighting: Besides in "Karate Choppers" and "Dunces and Dragons," SpongeBob is very bad at fighting. This is best exemplified in "Extreme Spots."
  • Gullibility: SpongeBob's gullible personality makes him prone to manipulation of others who use him for their gain or make him unknowingly hurt others, physically and emotionally.
  • Cowardice: SpongeBob often lacks the willpower to stand up for himself. Even his arch-nemesis Sheldon J. Plankton points this out in "Walking Small" when beachgoers were walking all over SpongeBob SquarePants (ironically enough, Plankton himself was forcing SpongeBob SquarePants to do his bidding in the same episode). Patrick Star even takes advantage of SpongeBob SquarePants in "Suds," "Hooky," and "Rock-a-Bye Bivalve." He's also shown to have numerous irrational fears such as the fear of clowns or the dark.
  • Driving (boatmobile): He is not good at driving because he always crashes into buildings and/or hits people with his boat



HaveYouSeenThisSnail SpongeBob and Gary Surrounded by Hearts

SpongeBob in joy upon Gary deciding to return to him at the end of "Have You Seen This Snail?"

It is suggested in "Have You Seen This Snail?" and "Treats!" that SpongeBob has had Gary ever since the former was a little boy, as it was also revealed that he was adopted. SpongeBob SquarePants is revealed to have bought him at the animal shelter in "Plankton's Pet." However, a flashback shown in The SpongeBob Movie: Sponge on the Run showcases that SpongeBob first met Gary at Camp Coral when he was a 10-year-old boy. SpongeBob then later adopted Gary when he got older.

As seen in "Ugh", their ancestors were shown to have a similar relationship.

Gary often serves as an advice-giver to SpongeBob SquarePants when no one else in Bikini Bottom is willing to help him. SpongeBob SquarePants often takes said advice despite it only being given in meows. However, SpongeBob occasionally takes advantage of Gary or forces him into situations against his will.

Patrick Star[]


SpongeBob and Patrick having a friendly pillow fight.

SpongeBob and Patrick have been best friends since they were born. It was seen in episodes "SB-129," "Ugh," and "Pest of the West" that their friendship even extends back to prehistoric times with their earliest ancestors and is passed down to their descendants, which shows their friendship runs deep in their families and both the SquarePants and Star family clans are presumably allies with each other, which is ironic considering that Starfish hunt and eat Sea sponges in real life.

The two have been certified members of the "Best Friends Forever Club," since they were very little, and to signify it, have rings of the club. SpongeBob SquarePants is one of the very few people who does not openly criticize Patrick for his brainlessness, and instead is the only one who thinks Patrick Star is smarter than himself, very often considering him to give good advice. However, SpongeBob did acknowledge that Patrick was an idiot in "Patrick SmartPants," which means he is actually aware the latter is not that smart and really humors him.

At times, Patrick Star often tries to give SpongeBob SquarePants the best advice he has even if it seems very illogical, as seen when he told SpongeBob there is always a shortcut in "Lost in Bikini Bottom." He is also shown to go to great lengths to keep the latter as a friend, as when SpongeBob gave up his regular life to live with jellyfish, Patrick tried to make SpongeBob his "trophy" just so that he and SpongeBob could be together again. He also shows great sorrow when not around SpongeBob, which he has mentioned frequently. He even followed SpongeBob SquarePants to the bitter end on their journey to Shell City. Though he has been on bad terms with SpongeBob many times throughout the series, they always come back together as best friends.

Squidward Tentacles[]

As seen in "Truth or Square," Squidward Tentacles was once living a happy life in Bikini Bottom with a fancy garden next to his house. One day, a pineapple fell off a boat and crushed his garden, immediately becoming the home of SpongeBob SquarePants after he moved into the neighborhood. Patrick appeared to have already been living next door to Squidward sometime before the incident.

Squidward-SpongeBob relationship

SpongeBob seems to be the character who Squidward is most annoyed by, but SpongeBob usually ignores this and is often very nice to Squidward despite he tends to annoy him, mostly by accident. However, there are times when Squidward goes too far with SpongeBob SquarePants, Patrick Star, or both, like when he reads SpongeBob's secret diary in "Little Yellow Book," overreacts to his neighbors even when they try to help him, makes fun of them, acts quite hypocritical when he says that they're the worst neighbors ever, tried to destroy their friendship a couple of times and even tried to kill them a few times, with the episodes "Naughty Nautical Neighbors," "Good Neighbors," and "Sportz?" being examples of that.

Throughout the show, there have been some instances where SpongeBob SquarePants was aware that Squidward was annoyed at him, such as in the episode "SpongeBob You're Fired," where Squidward Tentacles asks SpongeBob SquarePants if he knows he hates him and he replies "Yes, yes I do." In other occasions, SpongeBob is the one who gets mad at him. There are also a few instances in which SpongeBob feels concerned or worried for Squidward as well.

Eugene H. Krabs[]


Mr. Krabs hugging SpongeBob towards the end of The SpongeBob SquarePants Movie.

Most of the time, SpongeBob SquarePants cares deeply about his boss Eugene H. Krabs, follows his orders as his employee and has a deep respect for him.

However, Eugene H. Krabs' relationship with SpongeBob SquarePants can vary. Sometimes, particularly in early episodes, Eugene H. Krabs acted as a fatherly authority figure toward SpongeBob SquarePants, and he also states more than once that he's like a son to him. On the other hand, he can sometimes be mean to SpongeBob SquarePants and use him for his greedy expense, for which the latter may occasionally scold him, but in general, the two of them have a relationship that is very similar to the one between a father and his son.

Sheldon J. Plankton[]


SpongeBob SquarePants and Sheldon J. Plankton have a love-hate relationship. When SpongeBob SquarePants first met Plankton, he tries to befriend him, but as Plankton told him that he wants a Krabby Patty (and by extent, the formula) for his birthday, SpongeBob SquarePants refuses. From that point on, whenever Sheldon J. Plankton tries to steal the formula or a Krabby Patty, most of the time, SpongeBob SquarePants tries to stop him. However, despite this, they have been friends a few times.
