General tropes

Tropes held by the recurring cast in general.

---

• Ascended Extra: Nickelodeon officially designates 14 characters as "The Supporting Cast". However, seasons 10-12 have given bigger roles to a surprising number of formerly-minor characters, both old and new, with their prominence rivaling that of the official supporting cast. Fred, Rube, Bubble Bass, and Old Man Jenkins are just a few of the recent breakout characters.
• Breaking the Fourth Wall: The Bikini Bottomites have been dubbed "secondary characters" in universe on two occasions.
  • In the 2015 movie, a group of fish follows SpongeBob and friends to the surface... until one fish says "All secondary characters, come with me." sending the whole group away.
  • In Jimmy Neutron's Nicktoon Blast, SpongeBob sees the Krusty Krab customers and says "Hi, secondary characters!"
• Put on a Bus: Due to the show's long run, many recurring characters have sadly suffered this fate due to voice actors passing away or retiring. Mermaid Man, Barnacle Boy, and Grandma SquarePants have all been limited to cameos on pictures or minor mentions; the first two because of their actors' deaths, and the latter because of her actress's retirement. Word of God says that they have no intention of recasting said characters.
• Torches and Pitchforks: It's incredibly common for the secondary characters to gang together as an angry mob, wielding torches and pitchforks that they just happened to have. In "Sing a Song of Patrick", the Bikini Bottomites went after SpongeBob and Patrick, and passed a torches stand (yes, they burn, and yes, they're still underwater), a pitchforks stand, and a... cotton candy stand. After all, as the man said, "You can't go riot without cotton candy!"

Supporting cast

Patchy the Pirate

Patchy the Pirate

Played by: Tom Kenny
Debut: "Christmas Who?"

The host of the series' special episodes. He is a live-action pirate portrayed by Tom Kenny, the voice of SpongeBob. He is the president of the fictional SpongeBob fan club.

---

• Breakout Character: Following his debut in the Christmas show, Patchy became the host of several SpongeBob specials and marathons following his debut, as well as appearing on some Nickelodeon commercial segments. He even makes a guest appearance in Big Time Rush!
• The Bus Came Back: He returns in "Feral Friends" after years of only appearing in commercials and in stop-motion form ("It's a SpongeBob Christmas!").
• Butt-Monkey: The guy's a loser, according to the Narrator. His role in the specials is nothing but slapstick and being constantly thrown under the bus.
• The Chew Toy: He is subjected to many cartoonish injuries in the segments featuring him, such as being exploded in "Party Pooper Pants" or attacked by a T. Rex in "Ugh".
• Commuting on a Bus: During the specials made after "The Sponge Who Could Fly", Patchy would not have a subplot. Instead he would simply herald the episode as "A SpongeBob SquarePants Special". In fact, the only specials he had a role in during the post-movie era were "Friend Or Foe", "Atlantis Squarepantis" and "Truth Or Square".
• Dressed to Plunder: Wears the typical parts of a pirate costume, though he doesn't really do any actual plundering.
• Excited Kids' Show Host: He's played by Tom Kenny, who acts as an enthusiastic cartoon character in his sketches before introducing SpongeBob's segments.
• Fanboy: He's the president of the SpongeBob fan club.
• Friendly Pirate: During his segments he is seen as SpongeBob's number one fan, and although he can be depicted as a bit of a Jerkass, especially towards his pet parrot, he is mostly a pirate who doesn't do anything truly pirate-y.
• Iconic Sequel Character: Patchy debuted in the season 2 episode "Christmas Who?" and has since starred in live-action segments at least Once a Season.
• Iron Butt-Monkey: Has been blasted through multiple houses, eaten by a T-Rex, mauled by a polar bear and has had his head removed from his body twice, and still shrugs them off as no big deal.
• Manchild: He's a fully-grown man who's more obsessed with SpongeBob than most of the kids watching the show could ever be. For example, when he thinks SpongeBob betrayed the fans by starring in a mediocre sketch, he starts whining and decides to run away. He is even unaware of his idol's status as a fictional character and genuinely believes he is a real person (canonically speaking, he's not wrong).
• Named After the Injury: Subverted. He wears an eyepatch, being a pirate and all, but one episode reveals that the covered eye still works.
• Obsessive Spokesperson: He hosts several special episodes of SpongeBob, as well as SpongeBob promotional material. His house is filled with SpongeBob merchandise and he goes to extreme lengths to see new SpongeBob episodes, including a lost episode, and even tries to meet SpongeBob in person. Even his pirate getup seems to just be an extension of his SpongeBob obsession, since he lives in modern-day Encino, California.
• The Pirates Who Don't Do Anything: Despite being a pirate, we never see him doing any actual looting or plundering.
• Pirate Parrot: Has an obnoxious parrot on his shoulder named Potty.
• Suspiciously Similar Substitute: Replaced by "Captain Bart" in the first theatrical movie; Word of God indicated the Paramount execs didn't understand the appeal of the character, as "intentionally low production values scare them".
• Tantrum Throwing: In the Lost Episode, he starts crying and throwing all his SpongeBob merchandise away when he thinks SpongeBob betrayed him.
• Talk Like a Pirate: He speaks like a stereotypical cartoon pirate, heavily emphasizing the /r/ phoneme.
• This Loser Is You: He's an immature fanboy who has no life outside of SpongeBob. Nothing ever goes right for him, and Potty only seems to hang around him to make wisecracks at his expense. Even the narrator calls him a loser at the end of The Lost Episode and Friend or Foe.
• Throw the Dog a Bone: He finally gets to meet SpongeBob in person in "SpongeBob's Birthday Blowout".
• Token Human: Notably the only recurring character who is a live-action person.

Potty the Parrot

Potty the Parrot

Voiced by: Stephen Hillenburg (2000-2004), Paul Tibbit (2007-2012), Mr. Lawrence (2017-present)
Debut: "Christmas Who?"

Patchy's obnoxious, wisecracking pet parrot who is depicted as a crudely-made marionette puppet with very obvious strings and googly eyes.

---

• Ambiguous Gender: Potty lays an egg in two episodes, is directly referred to as her and she in the tie-in chapter books, and has a name that parodies Polly (a female name). However, Patchy says his when referring to Potty's voice in "Friend or Foe," and gender pronouns are never used for the character elsewhere. In 2017, showrunner Vincent Waller confirmed in in a tweet that "it is only a puppet, with no tell tale signs of gender".
• Bratty Half-Pint: An obnoxious parrot that messes with Patchy's show.
• Characterization Marches On: In his first appearance, Potty behaved more like a real parrot such as repeating minimal phrases and single words. In all his later appearances, Potty becomes more responsive and talks human-like. His first appearance shows him as either being less intelligent or Obfuscating Stupidity. He makes his annoyance at Patchy and higher intelligence obvious in later episodes.
• Deadpan Snarker: Often snarks at Patchy's mishaps.
• Egg-Laying Male: Despite being identified as a male parrot, Potty has been shown pressing a button in a remote control by laying an egg on it.
• The Ghost: Potty's puppeteer, who is ostensibly controlling Potty. The only time he's ever been seen was in "Christmas Who?", and even then than was only him falling from the ceiling after Patchy tugged on Potty's strings. (In reality, that was only a dummy falling from the ceiling.) Later episodes don't even seem to imply Potty has a puppeteer.
• Hypercompetent Sidekick: In "Friend or Foe", the duo is hired by a restaurant, with Potty quickly securing himself a promotion while Patchy earns his boss' scorn.
• Iconic Sequel Character: Potty debuted in the season 2 episode "Christmas Who?" and, much like his owner Patchy, has starred in live-action segments at least Once a Season.
• Polly Wants a Microphone: Like most parrots in fiction, Potty is able to speak instead of just mimicking what other people say.
• Sidekick Creature Nuisance: Potty constantly annoys Patchy and seems to enjoy it.
• Snarky Nonhuman Sidekick: Or, as Patchy puts it, "my less-than-amusing sidekick".
• Stylistic Suck: Looks like a cheap puppet that's falling apart (marionette strings are always visible) and can never change facial expressions. He even retains this look when animated.
• Temporary Bulk Change: In "Christmas Who?", he becomes fat from eating all of Patchy's unbaked cookie dough. He's so heavy he even causes the strings holding up his puppet body to snap and drop him.
• Third-Person Person: Playing on the stereotypical "Polly want a cracker" behavior, Potty talks like this in his first appearance. He drops it in his second appearance.
  Chirstmas Who?: Potty want cookie dough.
  Shanghaied: Help! I'm being held here against my will!
• With Friends Like These...: An annoying Deadpan Snarker who loves irritating Patchy... and yet seems to be Patchy's only friend.

French Narrator / "Frenchy"

The French Narrator

Voiced by: Tom Kenny
Debut: "Help Wanted"

A scuba diver with a camera who narrates episodes off-screen as if they were nature documentaries about the ocean. He is a Shout-Out to Jacques Cousteau, the famous oceanographer and filmmaker whose work was an influence on series creator Stephen Hillenburg. The episode Feral Friends marks the first time the French Narrator makes a major appearance.

---

• A Day in the Limelight: He plays a major role in Feral Friends where he was called by Sandy to explain the weird phenomenon that has turned her friends into actual marine lifeforms.
• Everyone Calls Him "Barkeep": He doesn't have a real name, and is solely known as the French Narrator.
• Mock Cousteau: Very clearly a Jacques Cousteau parody.
• No Celebrities Were Harmed: His French accent and the fact that he's narrating a show about anthropomorphic sea creatures are intended to be a reference to Jacques Cousteau.
• Verbal Tic: Tends to start his sentences with "Ah".
• The Voice: He usually only exists as a disembodied voice, but he appears physically in "No Free Rides" and "Feral Friends", where he is shown wearing a diving suit with a toque on the helmet.

Mermaid Man

Mermaid Man

"Eeeeevil!"

^{Click here to see his younger self.}

English voice: Ernest Borgnine (1999-2012), Joe Whyte (Employee of the Month and Battle for Bikini Bottom), Joe Alaskey (Lights, Camera, Pants! and Creature from the Krusty Krab), Adam West (young)
German Voice: Karl Schulz
Swedish Voice: Johan Hedenberg (Mermaid Man and Barnacle Boy), Peter Sjöquist (Mermaid Man and Barnacle Boy IV, V and VI), Mattias Knave (all other appearances)

Debut: "Mermaid Man and Barnacle Boy"

SpongeBob and Patrick's favorite superhero, who is now elderly and lives in a retirement home.

---

• Acrofatic: Despite putting on more and more weight due to his retirement, and also being very old, he still has the same agility as he had when he and Barnacle Boy were active superheroes.
• Ambiguously Human: He certainly looks human—at least, about as much like a human as you can get in the show's standard artstyle—but nearly all other humans in the series are depicted via Medium Blending and are shown to be far larger than the main cast, neither of which is true for him and Barnacle Boy. He doesn't look like the Atlanteans we've seen in the series, either. The character he's inspired by is most often half-human, half-Atlantean, but Mermaid Man himself has no clear origin story, which makes his true nature rather uncertain.
• Backported Development: In the TV Series, his younger self was usually depicted as a competent and skilled Superhero. In the comics, however, Mermaid Man's younger self is such a blundering fool he gives Powdered Toast Man a run for his money. This makes his younger self in the comics more like the the elderly Mermaid Man seen in the TV series and comics.
• Badass Driver: While he and Barnacle Boy usually have trouble finding the Invisible Boatmobile, Mermaid Man is really good at actually driving it, despite his old age and being as scatterbrained as he is. It's shown that this comes from experience in "Mermaid Man & Barnacle Boy II", as a newbie like SpongeBob doesn't know the first thing about how it functions.
• Batman Parody: What traits of his that aren't borrowed from Aquaman tend to be derived from Adam West's Batman (1966), such as the Invisible Boatmobile, a utility belt, and his younger self being voiced by West himself.
• Cloudcuckoolander: He has eccentric beliefs and habits. May be semi-justified as onset Alzheimer's/Dementia.
• The Cuckoolander Was Right: In "Mermaidman and Barnacleboy V", he refuses to order a regular Krabby Patty for Barnacle Boy on the grounds that it's too much for him to eat. Barnacle Boy interprets this both as him being condescending and too ridden with dementia to remember he's an adult, but much to his embarrassment, he has to concede the point at the end of the episode.
• Dub Name Change: As an example of the translators not getting the joke, Mermaid Man was known as "Tritón" on the first season of the Latin American dub. While Tritón is the correct way to refer to a "Mer-man", the joke was that his name was "mermaidman", as such, he was correctly named "Sireno Man" from season two onwards.
• Expy: His design and nature as an aquatic hero makes him a fairly clear parody of Aquaman, probably bearing the closest resemblance to the one in the old Filmation Aquaman cartoons. That said, he does tend to throw in Shout-Outs to other superheroes (the invisible boatmobile spoofing both Wonder Woman's Invisible Jet and the Batmobile, Saying Superman's catchphrase "Up, Up and Away!" whilst in a rocking chair, having a ring like Green Lantern and his and Barnacle Boy's powers activating by joining their rings together similar to the Wonder Twins).
• Fake Ultimate Hero: Of sorts. His and Barnacle Boy's heroism after becoming semi-retired is only informed. When they appear in an episode, it's usually SpongeBob and Patrick who end up saving the day. In the comics, Mermaid Man's younger self is such a blundering fool he gives Powdered Toast Man a run for his money.
• Fan Disservice: He goes around wearing a Seashell Bra on the outside of his clothing 24/7.
• Fat and Skinny: The fat to Barnacle Boy's skinny.
• Formerly Fit: He was very muscular in his prime, but after retiring, he became rounder and rounder to the point where he's basically a walking beach ball.
• Ink-Suit Actor: Looks exactly like Ernest Borgnine.
• I Was Quite a Looker: His younger self is more muscular and handsome.
• Lilliputians: He's the size of small sea creatures rather than a giant, like most human characters are portrayed as being.
• Large Ham: As Mermaidman is a walking parody of the corny superheroes from The Golden Age of Comic Books, he is prone to delivering bombastic speeches in response to mundane situations. This becomes a plot point in "Mermaid Man & Barnacle Boy VI: The Motion Picture", when his dramatic enactment of a previous battle inspires SpongeBob to finish recording the heroes' movie.
• Leitmotif: The Lineman is his associated theme.
• Miniature Senior Citizens: Judging by his appearance in flashbacks, he's gotten shorter and fatter with age.
• Nice Guy: Is much more sympathetic and friendly to SpongeBob than his sidekick Barnacle Boy, even if he does find SpongeBob annoying. He even lets SpongeBob go "on patrol" with them for a day, to show him what being a hero is like. "For a pain in the neck, he's a pretty nice kid!"
• Old Superhero: He was a superhero in his youth who eventually retired, but became "semi-retired" thanks to SpongeBob.
• Put on a Bus: Mermaid Man has been reduced to cameos on pictures or as a toy following Ernest Borgnine's death. In fact, it's become more common to see characters cosplay the character than the character actually appearing. Vincent Waller has stated that the character has been permanently retired from the franchise out of respect for Ernest Borgnine and Stephen Hillenburg's wishes that Ernest would never be replaced with a soundalike. The one exception was SpongeBob SquarePants: Battle for Bikini Bottom: Rehydrated, in which archived recordings of Joe Whyte as the character were reused by necessity.
• Retired Badass: He used to be a superhero, with Barnacle Boy as his sidekick, when he was younger.
• Scatterbrained Senior: Mermaidman shows signs of dementia due to his old age.
  • In his debut episode, he loses his train of thought while reprimanding SpongeBob and randomly starts acting as if he was officiating a wedding.
    Mermaid Man: Listen up, you villains! I wanna eat my meatloaf! If you don't get out of here, then by the power invested in me, I now pronounce you man and wife!
  • When SpongeBob ends up shrinking everyone in Bikini Bottom using Mermaid Man's belt in "Mermaid Man and Barnacle Boy IV" and he laments how he's sure Mermaid Man will be disappointed in him for what he's done, Mermaid Man assures him that won't be the case, but apparently forgets that he is Mermaid Man.
    Mermaid Man: Your mother's right, son. Mermaid Man will understand.
    Barnacle Boy: You're Mermaid Man, you old coot!
• Seashell Bra: Wears one over his clothes for some strange reason.
• Senior Sleep-Cycle: He can even sleep with his eyes open.
• Sleeps with Both Eyes Open: Ever alert, Mermaid Man has trained himself to sleep with his eyes open.
• Token Human: He is one of the few recurring human characters, yet is able to survive underwater. Apparently, some mermaids gave him a special starfish that allowed him to breathe.
• Took a Level in Kindness: In his first appearance, he was a Grumpy Old Man, but in his second appearance, he's much more jovial and gets along pretty well with SpongeBob.
• Trademark Favorite Food: Meatloaf. He's excited when Barnacle Boy tells him that Shady Shoals is serving meatloaf, and threatens to throw SpongeBob out if he doesn't let him eat his meatloaf.
• Trauma Button: Don't say the word "evil" if he's in earshot. He'll go nuts if he hears it.

Barnacle Boy

Barnacle Boy

"You old coot!"

^{Click here to see his younger self}

English voice: Tim Conway (1999-2012), Burt Ward (young)
German voice: Uwe Paulsen (Seasons 1-5), Hasso Zorn (Seasons 6-9)
Swedish voice: Hans Jonsson

Debut: "Mermaid Man and Barnacle Boy"

Mermaid Man's sidekick, who is also elderly and lives in the same retirement home.

---

• Ambiguously Human: Like his mentor, he doesn't match up with the other humans in the series, nor the Atlanteans, and he doesn't have any real origin story, making it hard to definitively say what he is.
• Atrocious Alias: Given that he lives in an underwater society where the word "barnacle" is sometimes used as an expletive, it's likely a factor as to why he's treated with less respect than Mermaid Man.
• Butt-Monkey: He is the main target of the show's slapstick comedy in the episodes he appears in. In "Mermaidman & Barnacleboy II", him being set on fire by the pipes of Mermaidman's boatmobile is a Running Gag, with the dirty bubble even implying that he regularly suffered said injury even when the two heroes were younger.
• Cloudcuckoolander's Minder: He frequently has to keep Mermaid Man out of trouble due to being the more rational and less senile of the pair.
• Eye Beams: He has "sulfur vision," but can barely get it to work the one time he tries to use it.
• Fat and Skinny: The skinny to Mermaid Man's fat.
• Gag Nose: He has a big nose, which leads to him and Squidward butting noses in "Mermaidman and Barnacleboy IV".
• Grumpy Old Man: He's 68 years old and doesn't take kindly to most people.
• Hypocritical Humor: In "Mermaidman and Barnacleboy IV", he calls Squidward "big nose", which even prompts the latter to lampshade this.
• I Was Quite a Looker: Like Mermaid Man, he was handsome and muscular in his youth.
• Jerk with a Heart of Gold: He's noticeably more of a jerk than Mermaid Man, being much less patient with SpongeBob and temporarily becoming a supervillain for petty reasons. That being said, he still cares about Mermaid Man and is a renowned hero for a reason.
• Kid Hero All Grown-Up: He's now old enough to live in a retirement home. Still goes by Barnacle Boy though.
• Leitmotif: Like Mermaid Man, "The Lineman" is used as his theme music.
• Lilliputians: He's the size of small sea creatures rather than a giant, like most human characters are portrayed as being.
• Older Than They Look: He looks more like an unattractive younger man than a 68-year-old.
• Old Superhero: He lives in a retirement home. It doesn't get older than that.
• Put on a Bus: Like Mermaid Man, he'll never get off the bus. With Ernest Borgnine's death, Barnacle Boy was retired along with him, barring the occasional cameo via photograph or toy. It became permanent with the death of Tim Conway in 2019, and Vincent Waller has stated that the character has been permanently retired from foreground appearances as well.
• Retired Badass: He used to be Mermaid Man's sidekick when they were both younger.
• Sarcastic Devotee: He doesn't have much tolerance for Mermaid Man's obliviousness, but he still sticks up for him when the chips are down. Even when he defects to the side of evil in "Mermaidman and Barnacleboy V", all he really wants is some appreciation.
• Straight Man: To Mermaid Man's antics. Notable since on McHale's Navy, the roles were flipped, with Conway as the wise guy and Borgnine as the straight man.
• Stuck in Their Shadow: invoked He rather resents always having to play the "young ward" of a now-senile old man (who wears a bra, no less), especially when he's the much more lucid of the two. This causes him to (temporarily) join the bad guys in "Mermaidman and Barnacleboy V".
• Temporarily a Villain: In "Mermaidman and Barnacleboy V", he became a bad guy just because Mermaid Man wouldn't let him have an adult size Krabby Patty. He turned back to normal by the end of the episode though.
• Token Human: And is somehow able to breathe underwater. Apparently, it was because of Mermaid Man's powers that he got the ability.

Flying Dutchman

The Flying Dutchman

English voice: Brian Doyle-Murray
German Voice: Hans Teuscher (Episodes 13–162), Michael Pan (current)

Debut: "Scaredy Pants"^note As far as physical debuts go, anyway. His actual debut was "Squidward the Unfriendly Ghost", though he was barely mentioned in a couple of book pages in that one.

"Who dares disturb the Flyin' Dutchman?!"

An old pirate who died a long time ago, but instead of being buried, he was used as a window display. As a result, he never found peace and continues to haunt the seas as a ghost, often aboard his ghostly ship.

---

• Affably Evil: When he's not antagonizing our heroes, he's shown to be a laid back kind of guy.
• Ambidextrous Sprite: There's a ragged hole in the brim of his hat that tends to favor the side facing the viewer, and will often switch places throughout the episode.
• Bad Is Good and Good Is Bad: He shows shades of this in "The Legend of Boo-kini Bottom", as he describes Halloween as the worst holiday after describing the things he likes about it and assures SpongeBob that he is in bad hands. And then there's how SpongeBob defeats him by letting him inside his mind and frightening him with the Sugar Bowl within.
• Big Bad: He is the main villain in Revenge of the Flying Dutchman.
• Dead Guy on Display: The Dutchman himself as part of his backstory; He's been cursed to wander the seas as a restless spirit because someone decided to use the Dutchman's corpse as a clothing store mannequin.
• Depending on the Writer: He flip-flops between a morally neutral Grim Reaper figure, a sadist who enjoys scaring people and stealing their souls For the Evulz, or a scary-but-benevolent ghost.
• Don't Fear the Reaper: He steals souls and is considered Bikini Bottom's version of The Grim Reaper, but the Dutchman is capable of having friendly, casual conversations with people on a regular basis, and is sometimes even shown to be friends with SpongeBob.
• Early-Bird Cameo: While his first physical appearance is in "Scaredy Pants", he made a brief appearance prior in a book Spongebob and Patrick read in "Squidward the Unfriendly Ghost".
• Eldritch Abomination: Of the undead variety. He bends reality to his whim, preys upon the living, degrading them both physically and psychologically and his very name and appearance is enough to shake even the most jaded and unfazed fish at their core.
• Even Bad Men Love Their Mamas: In "Shanghaied", he says insulting someone's ship is worse than insulting their mother, but doesn't actually attack Squidward until he becomes convinced he was actually insulting his mother.
• Even Evil Has Standards:
  • "Born Again Krabs" has him arrive to do his usual condemning someone to Davy Jones' locker deal, but upon being tricked into thinking he went to the wrong room, he apologizes and politely asks the nurse where Mr. Krabs' room is, not doubting "Harold Flower's" claim until the nurse questions it. Evidently, he's ruthless towards those he wishes to haunt but doesn't wish to inflict Misplaced Retribution.
  • In "Money Talks", not only does he looked surprised that Mr. Krabs was willing to sell his soul so eagerly and took the whole ordeal lightly, but he looked dumbfounded that Mr. Krabs sold his soul to other ghosts, monsters, and demons. Plus to SpongeBob because he was low on payday.
• Evil Is Hammy: The Dutchman really chews up the scenery when he's being evil.
• Final Boss: He's the last boss faced in Legend of the Lost Spatula and Revenge of the Flying Dutchman.
• Flying Dutchman: At least according to his backstory given in "Squidward the Unfriendly Ghost", he's forced to walk the earth forever because his body was never given a proper burial.
• Ghostly Goals: As SpongeBob helpfully explains:
  SpongeBob: When [the Flying Dutchman] died, they used his body as a window display. Now, he haunts the Seven Seas because he was never put to rest.
• Ghost Pirate: He is a classic Ghost Pirate, who possesses many supernatural powers. He also acts as an underwater Grim Reaper, who takes the souls of dead sea creatures to Davy Jones' Locker (which is a literal gym locker filled with dirty laundry, and as revealed in a later episode, is owned by the musician Davy Jones). In "Shanghaied", the Dutchman forces SpongeBob and Patrick to become crew members on his Ghost Ship, serving him as "ghostly ghost pirates" (though they're still alive). They're... not up to par.
• The Grim Reaper: In "Born Again Krabs", he tries to take Mr. Krabs' soul and bring it to Davey Jones' Locker.
• Humanoid Abomination: He is the ghost of a human pirate with a vast amount of supernatural powers and all marine life in his presence perceives him as a Lovecraftian being or the devil itself.
• Jackass Genie: SpongeBob once tried to outwit him by wishing for him to become a vegetarian. He did, but turned SpongeBob, Patrick, and Squidward into fruit.
  Flying Dutchman: (chopping a banana) Hey, I get a wish too! Fruit prevents scurvy!
• Jerk with a Heart of Gold: Sometimes. He rewards SpongeBob and Patrick with a gold dubloon each in "Arrgh!" for saving him the trouble of digging up his old treasure chest, and shows SpongeBob how to tie knots (though not his shoes) in "Your Shoe's Untied".
• Karma Houdini: He often avoids punishment for his mean actions. Considering he's a deadly pirate ghost with supernatural powers and is perceived by marine life as an Eldritch Abomination or the devil itself, it's not surprising.
• Karma Houdini Warranty: The Flying Dutchman does not always evade punishment. Every once in a while karma comes around to bite him, and when it does it bites hard.
  • SpongeBob succeeds in scaring him in both "Scaredy Pants" and "The Legend of Boo-kini Bottom".
  • SpongeBob SquarePants: Revenge of the Flying Dutchman takes this a step further with SpongeBob not only beating up the Flying Dutchman, but sealing him away in a bottle.
  • In SpongeBob SquarePants: Battle for Bikini Bottom he gets put through a Humiliation Conga: first the rampaging robots beat the crap out of him, then the robots steal his pirate ship, and finally Sandy beats him up in a boss fight.
  • In "Money Talks" he not only fails to get Mr. Krabs' soul, but he finds out several other spirits and demons beat him to getting a contract on Krabs' soul. Even SpongeBob.
  • In "SpongeBob Vs. The Big One" he gets thrown into Davy Jones' locker, where Davy Jones then proceeds to throw smelly socks at him.
  • In "The Ghost Of Plankton" he double-crosses Plankton, whose soul is currently outside his body, and steals his body. The Dutchman does not get to enjoy being flesh and blood though as he quickly gets ferociously stomped on by angry mourners and is forced to relinquish Plankton's body back to him.
• Leitmotif: His entrance into a scene is backed by the playing of "Malleus Mallificarum", an imposing piece with Ominous Latin Chanting.
• Monochrome Apparition: He's a ghost and glows sickly green.
• Nightmare Fuel Station Attendant: He's capable of transforming into all sorts of monsters, sending people down the Fly of Despair, and making odd knots.
• Not Even Bothering with the Accent: Despite the character being Dutch, Brian Doyle-Murray uses his normal Irish-American accent for the role.
• One-Winged Angel: The Flying Dutchman abuses the ability to take on larger and scarier forms in "Ghost Host" to the point of deconstruction.
• Our Ghosts Are Different: This one's a deadly pirate ghost who was cursed to spend eternity as a restless spirit because he never got a proper burial. He has a wide variety of supernatural powers (though he's not invincible), and his job as a ghost runs the gamut of scaring people for fun, spiriting away the souls of the dead, ruling the underworld, making unholy bargains in exchange for souls, and granting wishes that always come at a terrible price.
• Peek A Bogey Man: As he puts it in "Shanghaied!", his job is to "sail around and frighten people".
• Reality Warper: One of his scary features is his ability to change his surroundings at will, especially in "Ghost Host".
• Red Eyes, Take Warning: His eyes glow red when he confronts SpongeBob over not being afraid of anything in "The Legend of Boo-kini Bottom".
• Satanic Archetype: He is the closest character in the show that matches Satan in terms of behavior. He is known for tearing out souls and placing them in his soul bag or just straight-up eating them, and one of his favorite hobbies includes trying to psychologically traumatize whatever poor soul catches his sight. He makes deals with people such as with Mr. Krabs when he threatened to send him to Davy Jones' locker if he were to return to being cheap. In that same episode, he inadvertently sells SpongeBob's soul for sixty-two cents.
• Sickly Green Glow: His body glows green.
• Talking in Your Sleep: He mutters "I'm the Flying Dutchman" in his sleep in "Arrgh!".
• Time Master: Parodied, when Patrick wishes he knew about the wishes earlier, he turns back time by one minute.
• Time Abyss: In Season 7's "The Curse of Bikini Bottom", after the Dutchman gets accidentally shaved by Spongebob and Patrick, he claims it will take a thousand years to grow back. However, he is shown with a full beard in that same episode after a timeskip of several months.
• Voluntary Shapeshifting: The Dutchman can change his appearance at will as a way to scare people.
• Your Soul Is Mine!: He collects people's souls, either to take them to the afterlife or just for the hell of it. He's also usually (but not always) seen carrying a handbag marked with the word "SOULS."

King Neptune

King Neptune

Voiced by: John O'Hurley
Debut: "Neptune's Spatula"

The king of the sea.

For his movie counterpart, see: Sponge Bob Square Pants Movie Characters

---

• The All-Solving Hammer: His trident has the ability to spawn anything into existence, transport him from one place to another, and destroy any enemy in his path. It's a dandy little device that can definitely do it all.
• God: King Neptune is pretty much Bikini Bottom's equivalent of God. He's, in one way or another, worshipped by the bikini bottomites and recognized as somewhat of a diety. He has godlike powers and has a whole Groman God feel to his character. Also, characters use his name in vain, via phrases like "Oh my Neptune", "For Neptune sake!", and "What in the name of Neptune?". You can replace his name with "God" and it fits perfectly.
• Jerkass Gods: King Neptune acts like a condescending jerk to all of the mortals of the sea. In "Neptune's Spatula", he even laughs in the face of SpongeBob for his inferior patty making skills, bringing the latter nearly to tears. He can be a Jerk with a Heart of Gold when in the right mood though.
• Large and in Charge: King Neptune is much larger than all of the mortal characters of the series, towering over all of them like a moving mountain.
• Lord of the Ocean: Given this show is set under the ocean, "Lord of the Ocean" basically means "Lord".
• Messianic Archetype: Though not specifically appearing as a Christian god archetype, King Neptune usually gives off the feel of being a religious figure of sorts.
• Pet the Dog: After SpongeBob's spatula and Neptune's trident get mixed up, the former accidentally wreaks total havoc. When Neptune sees the mess SpongeBob made, though, he isn't mad at all, he happily forgives SpongeBob and praises his spatula for being a useful tool in its own right.
• Prongs of Poseidon: King Neptune always wields with him a large trident.
• Redhead In Green: King Neptune is a redheaded merman with green skin.

Larry the Lobster

Larry the Lobster

English voice: Mr. Lawrence (most speaking appearances), Bill Fagerbakke (grunts in "MuscleBob BuffPants")
German Voice: Jörg Hengstler

"I have a date with the tanning booth."

Debut: "Ripped Pants"

A handsome, muscular lobster that gets all the girls. Almost always seen at Goo Lagoon or in crowd shots.

---

• Ambiguously Related: A line of dialogue in "SpongeGuard on Duty" implies he was raised by a (now elderly) fish couple, though it is never elaborated on in any other episode.
• Beware the Nice Ones: A pretty friendly guy, but not someone you'd want to anger considering his size, which Squidward learns in "Squid Plus One" and "Gary's Playhouse".
• The Big Guy: He's a lifeguard with a muscular physique.
• Characterization Marches On: Early on there was some indication that Larry was intended to be portrayed as a jockish bully to SpongeBob, evidenced by his appearance in Revenge of the Flying Dutchman (see Out-of-Character Moment) and lyrics in the "Ripped Pants" song claiming that Larry came to bully SpongeBob into his ripped pants shtick. However, this never stuck, and Larry was instead characterized as a Lovable Jock and an all around Nice Guy.
• Charles Atlas Superpower: His training practically made him strong enough to lift 2 bleachers full of audience members.
• Chick Magnet: He's popular and gets all the girls.
• A Day in the Limelight: After years of only appearing as a side or background character, he was made the focus of a Season 9 episode, Larry's Gym.
• Eye on a Stalk: Has stalk shaped eyes similar to Mr. Krabs, but yellow and much smaller.
• Fitness Nut: Larry is most frequently seen exercising at Goo Lagoon. Two episodes in season one have him compete in feats of strength, while "Bubble Buddy" sees him gnaw on celery on the mistaken belief he was called fat. In "Larry's Gym," he opens up a successful gym, but steps down because the time he needs to spend on paperwork prevents him from working out. The spin-off Kamp Koral casts a young Larry as the councilor for a cabin full of tough, fitness obsessed young fish like him.
• Half-Dressed Cartoon Animal: Larry the Lobster's everyday attire consists of a pair of swim trunks and nothing else. He does wear a shirt in Kamp Koral, however.
• Jerk Jock: He had some shades of being one in early episodes, especially in "Ripped Pants", and in current episodes can still be rather condescending towards obvious weaklings like SpongeBob and Patrick.
• Lovable Jock: Easily the physically strongest character and one of the friendliest after SpongeBob himself.
• Nice Guy: One of the nicest characters in the series, he is jovial and very patient with SpongeBob's eccentricities.
• Only One Name: Only known as Larry the Lobster.
• Out-of-Character Moment: In the game SpongeBob SquarePants: Revenge of the Flying Dutchman, he's weirdly hostile towards SpongeBob, telling him that being seen with him would ruin his reputation, amongst other things.
• Red Live Lobster: Has the color of a boiled lobster. Justified by that he tans a lot.
• Spell My Name with a "The": His full name is Larry the Lobster.
• Third-Person Person: Inexplicably becomes one in "Larry the Floor Manager", him constantly referring to himself in the third person.
• Thrill Seeker: Larry is a huge adrenaline junkie who does a lot of crazy stuff. SpongeBob one time tried to emulate him, to disastrous effects.
• With Great Power Comes Great Responsibility: He very much values the importance of a lifeguard's job, telling Spongebob in "SpongeGuard On Duty" that the best part of being a lifeguard is being there to save people.

Realistic Fish Head

Realistic Fish Head

Voiced by: Mr. Lawrence, Tom Kenny ("Suction Cup Symphony"), Dee Bradley Baker ("No Free Rides")
Debut: "Help Wanted" (in the intro), "Mermaid Man and Barnacle Boy" (in an episode)

A realistic tuna who works as an anchorman and announcer. His partner, Perch, acts as a field reporter. He is featured in the opening sequence, and he narrates the in-universe Mermaid Man and Barnacle Boy show.

---

• Chuck Cunningham Syndrome: His appearances after season 3 dwindled, averaging roughly one appearance per season (in seasons 4, 6, 7, 8, and 9) in favor of anchor Perch Perkins, who also serves the reporter role.
• Non-Standard Character Design: He's represented as a photograph of an actual fish in a traditionally animated cartoon. And he mentions he's aware of it in "The Fry Cook Games".
• Only Known by Their Nickname: He only introduces himself as "Realistic Fish Head." He has had a plethora of given names in throwaway lines and tie-in media: Elaine, Mr. Fish, Johnny, and even T. McTrout of Trout TV News.

Perch Perkins

Perch Perkins

Voiced by: Dee Bradley Baker
Debut: The SpongeBob SquarePants Movie

"Mr. Krabs, what inspired you to make the Krusty Krab 2?"

An on-the-scene news reporter in Bikini Bottom. He is the co-worker of the Realistic Fish Head. He was created for the first movie and eventually made his way into the main series.

---

• Alliterative Name: Perch Perkins
• Canon Foreigner: He was originally created for the first movie, but later became a recurring character in the series proper.
• Casual Danger Dialogue: Perch Perkins usually seems to be completely unfazed by the terrible things going on in the world, as he does a news report on them and just continues to sport that newsworthy smile as he happily tells his viewers what horrifying disaster is befalling the city.
  Perch: Mr. Plankton, we've received a word that you're plotting to infiltrate the Krusty Krab and steal the Krabby Patty secret formula. [shoves Plankton a microphone to speak into] Is that true?
• Coincidental Broadcast: Perch Perkins does news reports on topics that just so happen to conveniently move the plot of the episode along.
• A Day in the Limelight:
  • Although it wasn't an episode, the short, "Krabby Patty Report" heavily focused on Perch Perkins getting addicted to frozen krabby patties and going insane over them.
  • The Kamp Koral episode "Gimme a News Break" focuses on both Perch and his cameraman Harvey interviewing people before investigating a conspiracy revolving around aliens supposedly invading the eponymous summer camp.
• Deadline News: If Perch Perkins does a news report on something disastrous or deadly, you can guarantee he's going to become the victim of it mid-report.
  Perch: Bikini Bottom is literally in a state of chaos and panic!
  [A muscular fish comes by and punches Perch to the ground; Perch gets up with a black eye]
  Perch: We go now to News Sea Chopper 7.
• A Dog Named "Dog": Perch is, well, a perch.
• Inconsistent Coloring: He was originally purple, but the crew changed him to orange for all of his in-show appearances until mid-season 9. This was because Paramount previously barred the show from using its movie-exclusive elements, including the Goofy Goober restaurant and Perch's color scheme from the movie. When the ban was lifted, Perch began alternating between orange and purple.
• Insult Comic: Perch Perkins has the tendency to make some not-so-subtle and eloquently worded insults against the people he does reports on.
  Perch: And here comes Squidward Tentacles and what must be either a bizarre piece of performance art or the saddest display of loneliness it has ever been my displeasure to report. One is inclined to suspect the second thing I said. A thing about sadness!
• Mr. Exposition: Some episodes open with news reports by Perch Perkins, giving the audience an explanation on what the episode is gonna be about.
• Only Sane Man: In Sponge out of Water, he is the only citizen (aside from SpongeBob and Plankton) who doesn't give in to the apocalypse of a Krabby Patty-free Bikini Bottom and is instead trying to do his normal news report.
• Rage Breaking Point: Although Perch is usually a pretty chill guy, SpongeBob and Patrick have been known to piss him off during reviews.
  Perch: At this time, survival looks bleak for this little yellow sponge.
  [Patrick continues to sit around, eating cotton candy, doing nothing]
  Perch: Hey, doofus!
  Patrick: Huh?
  Perch: Your best buddy is trapped in the Tunnel of Glove and may never escape!
• You Don't Look Like You: Perch has gone through tons of changes in his physical appearance over the course of the show both in body shape and in color scheme. It took about nine seasons before Perch finally got adjusted to the appearance he has today, though even now, we'll sometimes have episodes where he appears as either orange or purple.

The Bikini Bottom Fish

See: Sponge Bob Square Pants Minor Characters

Jellyfish

Jellyfish

Voiced by: Tom Kenny
Debut: "Tea at the Treedome"

The show's analogy of bees, jellyfishes inhabit Jellyfish Fields, although they occasionally wander to other places. Jellyfishing, the activity of capturing jellyfishes using nets, is SpongeBob and Patrick's favorite hobby. Their progenitor is the King Jellyfish, a huge jellyfish wearing a crown and cape.

---

• Beware the Cute Ones: Jellyfish may be cute but they sting like the dickens and many of them have been proven to be violently dangerous, putting characters like Squidward in traction ("Jellyfishing") and giving Dr. Manowar a gigantic permanent blemish that hurts when it's touched ("I'm Your Biggest Fanatic").
• Bee Afraid: They are a bee quivalent, after all. Expect someone to get zapped by their sting whenever they appear.
• Big Bad: Queen Jellyfish in "Jellyfishing".
• Bullying a Dragon: SpongeBob, Patrick, and other "jellyfishers" do this as an everyday hobby, walking straight up to deadly, weaponized animals and catching them in nets.
• Electric Jellyfish: Jellyfish have the ability to sting people with the stingers, sending many volts of electricity through their bodies.
• Elite Mook: The blue jellyfish in "Jellyfish Hunter" is highly intelligent, repeatedly avoiding SpongeBob's attempt to capture it. In some games, blue jellyfishes are treated as more durable enemies compared to normal pink jellyfishes.
• Fantastic Fauna Counterpart: They're the equivalent of bees in the human world, though they also incorporate aspects of butterflies (it's common for humans to collect butterflies, less so with bees) and cows (SpongeBob is seen "milking" a jellyfish for its jelly).
• Furry Confusion: Fish, sponges, starfish, octopuses, etc. are "human animals", while jellyfish, snails, amoebas, and worms are the "animal animals" in the SpongeBob universe.
• Gigantic Adults, Tiny Babies: King Jellyfish and similar sized jellies are extremely dangerous and huge compared to normal ones. While the worst normal jellyfishes stings do range from irritation to minor injuries, Royal Jellyfish' sting can destroy a house.
• The Goomba: In most SpongeBob Licensed Games, the jellyfish usually serve as the most common and basic enemy the player will encounter and are rather easy to defeat. Sometimes, they're passive unless provoked, while at other times, they're agressive and will swarm the player in droves.
• Harmless Electrocution: "Harmless" being used loosely. Sure, nobody can actually die from a jellyfish sting, but they still get painfully injured and sometimes even permanently damaged.
• King Mook: Named jellies such a King Jellyfish or Big Lenny are often more dangerous than the nameless normal jellies
• Monster Progenitor: King Jellyfish. In other episodes, it's the crownless, capeless Queen Jellyfish instead.
• Mooks: They're easily the most common creature in Bikini bottom and some of the most basic.
• Our Dragons Are Different: In "Dunces and Dragons", Planktonamor's weapon is Dragon Jellyfish, who is King Jellyfish with a mane instead of a crown and cape.
• Pun: Jellyfish literally secrete jelly, an edible condiment popularly used for sandwiches like Krabby Patties.

Bikini Bottomites

Bubble Bass

Bubble Bass

"You forgot the PICKLES!!!"

Voiced by: Dee Bradley Baker
Debut: "Pickles"

An obese, picky fish who was a nemesis to SpongeBob in an episode of the first season. He returned as a common patron of the Krusty Krab in season nine.

---

• Alliterative Name: Bubble Bass.
• Ascended Extra: Originally a minor character in Season 1, Bubble Bass has been promoted to the status of a recurring regular since Season 9, after falling from the face of the Earth for several years (outside of the video games, where he had made sporadic appearances), and now has far more prominence than ever before.
• Basement-Dweller: In "Moving Bubble Bass", it is revealed that he lives in his mother's basement, and when he gets fed up with his mother interrupting his fantasy talk show and making him do chores, he tricks SpongeBob and Patrick into helping him move his belongings to his grandmother's basement down the street.
• Big Bad: He's this for most episodes where he plays a big role. Since Season 9, he's also the most recurring villain, besides Plankton.
• Big Eater:
  • A fan translated his order to be a Krabby Patty with over twenty patties.
  • In "F.U.N.", he took off running when SpongeBob threw a single piece of popcorn.
  • In "Larry the Floor Manager", he nonchalantly orders a quadruple Krabby Patty, and in "Moving Bubble Bass" he casually eats two whole meals in one bite.
  • In "SpongeBob's Place", he leaves with a massive pyramid of Krabby Patties on his person.
  • In "Bubble Bass's Tab", he first orders a massive pile of food which includes a giant donut as big around as he is; then he tries to order fifty Krabby Patties via the drive-thru window.
  • In "Sea-Man Sponge Haters' Club", he notes that he was having a "light snack" between "first and second lunch"... said "light snack" being a towering bucket of large Krabby Patties, three huge boxes of fries, and a large hot dog. He also easily eats SpongeBob and goes back to eating.
  • In "BassWard", he spends the entire episode constantly eating snacks and even has his own personal cheese fondue pot that's about as big around as he is.
• Breakout Character: He was a minor character in Season 1 and vanished from the series afterwards, but his popularity eventually resulted in him being brought back roughly 16 years later as a prominent secondary character who's even gotten a few spotlight episodes.
• Brilliant, but Lazy: It's shown on several occasions that Bubble Bass is actually very intelligent and has aspirations to become the host of his own talk show. However, instead of using his intelligence to improve himself and pursue what he wants, Bubble Bass instead merely focuses on having fun at the expense of others, gorging himself on comically huge amounts of food and just being an outright unpleasant individual. The mix of his immaturity, laziness and spitefulness prevents him from using his intelligence productively and causing his life to ultimately go nowhere, thus making him the hopeless Basement-Dweller he is now.
• The Bus Came Back: Bubble Bass first made a few appearances in Season 1, before having an 11 year absence. Since his retintroduction into the series in Season 8, he's been promoted to the status of recurring character and has had numerous small roles, and even a few big ones.
• Cannot Talk to Women: It's not been explicitly touched on, but his appearance in The Patrick Star Show shows him very interested in anime cat girls, unsurprisingly suggesting his love life with actual women is non-existent.
• Characterization Marches On: In his initial appearances, Bubble Bass' characterization boiled down to being a total douche whose entire reason for being was both as a snobbish glutton and as a sadistic jerk who antagonized SpongeBob however he could. Later episodes maintain his initial character trait, but also reformed him into something akin to a local nerd, who lives in his mother's basement and whose interests include playing roleplaying games and collecting action figures and comic books. While he's still a pompous ass, he doesn't go out of his way to make SpongeBob's life miserable or treat him as an arch-enemy of sorts - and now usually makes the life of everybody he interacts with miserable, no longer regarding SpongeBob as his main target. By "Sea-Man Sponge Haters’ Club," he has joined a club that hates SpongeBob but doesn't actually wish him harm, a far cry from the sadistic joy he took in trying to mentally break him in "Pickles". While only lightly touched on in his first appearance, his Villainous Glutton trait is also played up since his appetite frequently causes problems for the other characters and himself.
• Chuck Cunningham Syndrome: He played a major role in "Pickles" and was built up as a recurring enemy of SpongeBob's, but completely disappeared from the show for years, due to Plankton becoming a Breakout Villain. Since then, the creators seem to have realized his small cult following as he's begun to become a more recurring extra in the series. Prior to his "return", he did pop up in video games from time to time.
• Comically Oversized Butt: Being overweight means Bubble Bass also has a very large bum. Many jokes revolving around Bubble Bass tend to emphasize just how massive his buttlocks are.
• Dagwood Sandwich: His famous order from "Pickles", even though it's never actually seen. Four burger patties with lettuce, tomato, and onion on two slices of toast is already quite the tall order, and Bubble Bass is basically asking for that, multiplied by six and stacked together.
• A Day in the Limelight:
  • Bubble Bass was heavily featured as the main character of "Swamp Mates", with Patrick being the secondary protagonist and SpongeBob barely even appearing at all, only making a brief cameo at the beginning of the episode.
  • Subverted in "Moving Bubble Bass". Despite being the titular character and the plot focusing on his move across town, the episode focuses almost entirely on SpongeBob and Patrick's antics, since Bubble Bass conned them into doing all the work for him.
  • "Bubble Bass's Tab" heavily revolves around his conflict with SpongeBob and Squidward as they try to get him to pay the huge tab he's accumulated at the Krusty Krab.
  • "The Big Bad Bubble Bass" is a fairy tale episode told about his quest to claim a new, valuable toy from SpongeBob and Patrick.
• Didn't Think This Through: Several times.
  • In "Moving Bubble Bass" he sees the boys are just the kind of idiots he can con into moving his stuff for him, but that's just it - they're idiots who he forces to do all the work, including packing his things, for him. Naturally, SpongeBob and Patrick make a complete mess out of his things even if they hadn't accidentally packed up his mother and sent her on a violent crusade at the end of the episode.
  • In Bubble Bass's Tab, he just keeps massing up a massive tab at the Krusty Krab and clearly had no intention of paying it off. When Mr. Krabs finally has enough and forbids Bubble Bass from eating any more food from his restaurant, Bubble Bass tries to flip a coin and play a game, but all it does is anger Mr. Krabs. Then after Bubble Bass runs away, Spongebob and Squidward are sent after him and beat him at Three Deadly Challenges. Clearly, if Bubble Bass hadn't built up such a massive tab or even started one in the first place, he wouldn't have gotten into trouble. He only got off paying for it because the Krusty Krab patrons paid it off to get rid of him.
• Dirty Coward: Bubble Bass loves to act smug and condescending, especially when he's in control of a situation. However, as soon as the tables turn on him (Bubble Bass's Tab) or he's caught in the act (Pickles), he chooses either to run away to avoid facing the consequences of his actions or cries to his mother for help.
• Easily Forgiven: As SpongeBob is an All-Loving Hero and Mr. Krabs will take money from anybody, they don't mind that Bubble Bass returns as a regular customer of the Krusty Krab and often have perfectly civil conversations with him, even though he nearly destroyed their entire business and SpongeBob's mental health out of spite. Later seasons also see him still on decent terms with the characters even after a bit more serialization kicks in.
• Embodiment of Vice: Two.
  • Sloth. Bubble Bass is notoriously lazy as he prefers to spend his time playing with his toys, reading comics and eating fast food. He refuses to look for a job and cowers in fear at the very idea of having to pay the massive tab he owes at the Krusty Krab.
  • Lust. Bubble Bass only cares about his own personal pleasures with no regard of how his actions affect others. He is unrepentant in his pleasure-seeking lifestyle, only focusing on what he wants to do rather than what he needs to do.
• Even Evil Has Standards:
  • He joins Squidward's anti-SpongeBob club, with said club's motto being that they don't actually want something bad to happen to the sponge.
  • In "BassWard" he is horrified when he and Squidward accidentally lose a baby and their mother out of the window of a train.
• Evil Is Petty: Especially in Season 1. If he can get away with spiting someone, he'll do it. Even though there are plenty of open seats in the movie theater in "F.U.N.", once SpongeBob tells him he's sat on his friend, Bubble Bass cruelly sinks himself into the seat further.
• Evil Laugh: Lets out a bleating cackle when he thinks he's bested SpongeBob. It's almost like an evil version of SpongeBob's iconic dolphin laugh.
• Fan Disservice: Who really wanted to see his tremendous ass slowly jiggling up and down in "F.U.N."? His later appearances also frequently display his corpulent physique in extreme detail, especially his gigantic ass.
• Fat Bastard: He's really not very nice, nor is he fit. When he's fleeing the Krusty Krab when he's been exposed, he's wheezing as he pathetically lumber-jogs off.
• Fat Slob: Bubble Bass constantly eats large amounts of food and tends to be a very messy eater at times. The Patrick Star Show episode "Bubble Bass Reviews" even has Patrick claim that Bubble Bass has been shown getting food stains all over his clothes at least 500 times.
• Fatal Flaw: Immaturity. At the core of Bubble Bass’s unpleasant personality is his immature behavior. His immaturity contributes to his many bad habits of spiting and bullying people for his own amusement, gorging on comically huge amounts of food, being financially irresponsible, being far too lazy to get a job and stop mooching off of his mother, prioritizing his personal pleasures above all else with no regard for how his actions affect others, never learning from his mistakes despite getting his comeuppance, and ultimately being someone no one takes seriously as a threat because of how pathetic, cowardly and lazy he is despite his rude and condescending behavior. Many of the situations Bubble Bass finds himself in are often of his own making, from destroying SpongeBob's confidence in 'Pickles' to amassing a massive tab in 'Bubble Bass's Tab' due to his own immaturity. If Bubble Bass would simply grow up and stop acting so unpleasant, he'd perhaps be doing far better in his life. Instead, he's simply too immature to do so and remains a Spoiled Brat in a grown adult's body.
• Foil: To Squilliam Fancyson. Both of them are Hate Sink Green and Mean jerks with no redeeming qualities who were introduced as an Arch-Enemy to leading characters (Bubble Bass for SpongeBob, Squilliam for Squidward). They are both arrogant, condescending, unpleasant and love to spite others just for fun (Squilliam by rubbing his wealth in others' faces, Bubble Bass by causing problems for others and harassing them). Bubble Bass is a Fat Bastard and a Basement-Dweller is far too lazy to get a job while Squilliam is a Lean and Mean Rich Bastard due to his successes in life. Bubble Bass is disdained by everyone due to his spiteful and immature behavior while Squilliam has a circle of friends (even though they're most likely sycophants). Both of them love to behave superior to others, though Squilliam was genuinely successful in his life (he just chooses to be a dick about it) while Bubble Bass is very unsuccessful as he has no job, no way of improving his life and is ultimately a pathetic loser who's too lazy to achieve what he wants. Both of them suffer from a Fatal Flaw that often leads to their downfall (Pride for Squilliam, Immaturity for Bubble Bass).
• Gasshole: Later seasons depict him frequently belching a huge plume of noxious gas, no doubt a consequence of a poor diet that consists largely of burgers and fast food. "The Big Bad Bubble Bass" claims that this is also something expected of him, as his mother chastises him for not being able to belch forcefully enough to blow down Squidward's house.
• Geek Physiques: Bubble Bass is of the "fat nerd" type. He constantly eats large amounts of food and naturally puts on quite a bit of weight as a result, a trait that would complement his later characterization as a Basement-Dweller geek.
• Green and Mean: He's a brown-green bass who has done his share of jerkish actions.
• Harmless Villain: Whenever he serves as an antagonist after "Pickles", he's a pretty pathetic threat in his own right due to being an out-of-shape, cowardly loser. In "F.U.N.", SpongeBob gets rid of him simply by throwing some stray popcorn for him to eat, and by Season 9 he’s usually reduced to begging for mercy after he gets defeated.
• Hash House Lingo: As part of his "burger connoisseur" role, Bubble Bass is an expert in esoteric frycook terminology, and famously once orders a massive multi-decker burger using a barrage of lingo terms that Squidward can't even decipher. They're all real American frycook lingo terms, though a couple are slightly modified to make sense in an undersea setting.
• Hated by All: Bubble Bass firmly causes himself to become this when he's exposed as a cheating fraud in "Pickles". Even with the loose continuity of the series not mentioning this event much afterwards, most of Bubble Bass's subsequent appearances show that everybody hates him for his foul, obnoxious attitude. Sometimes it's because he takes too long to come up with an order, sometimes it's because he's actively harassing and making people's lives miserable - and sometimes he's unintentionally making people's lives miserable. Either way, Bubble Bass won't win Most Beloved Citizen of Bikini Bottom anytime soon.
• Hate Sink: In Season 1 he exists to be a cruel, unlikable bully. From Season 8 onward, he occasionally teams up with SpongeBob against a common foe and becomes not quite as outright detestable, even pitiable due to being a hopeless basement dweller. Even then, his unpleasant personality, gluttonous appetite, utter spitefulness and laziness often makes him lose any sympathy from viewers.
• The Hedonist: Bubble Bass is devoted to doing the things he likes most - eating lots of food and indulging in his nerdy interests like toys and comic books. He doesn't have a job or any ability to better himself as a consequence.
• Hidden Depths: While a thoroughly unpleasant individual in pretty much all respects, he also clearly knows a lot about comic books and role-playing games. His fantasy about having his own talk show suggests he really does want to be a successful, beloved TV star in his own right.
• His Own Worst Enemy: Bubble Bass is surprisingly very intelligent when he wants to be and has legitimate aspirations to become a TV Star one day by hosting his own talk show. As per all his crippling flaws, Bubble prefers to indulge in immature behavior, gorge himself on huge amounts of food, cause problems for others for his own entertainment and is too lazy to get a job and improve his life.
• It's All About Me: At the end of the day Bubble Bass is most concerned with himself and making himself happy, the effects it has on others be damned.
• Jerkass: He's this more than anything else - in his first appearance, he nearly robbed SpongeBob of his self-confidence for no reason whatsoever.
• Jerk with a Heart of Gold: In "SpongeBob's Big Birthday Blowout", Bubble Bass helps set up SpongeBob's party and even joins in singing "Happy Birthday" to him.
• Jerk with a Heart of Jerk: In "Moving Bubble Bass", he offered SpongeBob and Patrick each a free meal from the Krusty Krab, if they helped him move out of his mother's house. By the end, despite them both helping him, he ends up eating both meals, while burping in their faces.
• Joke of the Butt: Bubble Bass can rarely go an episode without at least one gag revolving around his massive toosh, such as rubbing it into his seat in "F.U.N." after being told that he was sitting on Plankton, rubbing it against a window while taunting Mr. Krabs in "Bubble Bass's Tab," or having it be used as a makeshift ramp in "Delivery to Monster Island."
• Karmic Butt-Monkey: Bubble Bass tends to get struck by some form of misfortune on a regular basis. Since he's always a massive jerk to everyone, any instance of him suffering is usually well-deserved.
• Kick the Dog:
  • His treatment of SpongeBob was already bad, but throwing the relatively innocent Squidward (who made a crack at his obesity) around was even worse.
  • When told he is sitting on a friend of SpongeBob's at the movie theater, his response is to smirk and rub his ass deeper into the seat.
  • "Moving Bubble Bass" sees him scam the boys into doing his move for him, and he cruelly reveals he ate the free lunch he promised them as a reward just to spite them further.
• Laser-Guided Karma:
  • After his poor treatment of SpongeBob and Patrick in "Moving Bubble Bass," the two inadvertently destroy several of Bubble Bass' belongings while packing them up, ruins his mother's house, and accidentally pack his mother with his belongings, who then packs him into a box and starts ramming him into stuff as payback for what she had to endure.
  • In "Bubble Bass's Tab", after running up a huge debt at the Krusty Krab, he is eventually defeated by the crew and forced to work off his tab on janitor duty.
• Lazy Bum: He mostly devotes his time to eating food from the Krusty Krab and playing with his toys and collectibles. He outright cowers in terror when Mr. Krabs orders him to pay his tab, and later is so bad at janitor duty that the patrons of the Krusty Krab pay his tab for him to get him out of their hair.
• Manchild: He generally comes off like a spoiled brat in a twenty-something's body. He recklessly spends his money on toys and personal pleasures despite not being willing to take on a job, showing he's not financially responsible. What drove him to try to move out of his mother's house at one point was being ordered to take out the trash. He's prone to bullying and immaturely mocking people (such as singing a childish song in front of Mr. Krabs after being caught trying to order more food despite racking up a massive tab). He also acts like he can't stand his mother, but also lives in fear of punishment from her and will pathetically cry for her nonetheless if he's in trouble. And he usually doesn't learn his lesson even when he gets his comeuppance. To his mother's credit, however, she is fully aware of what a pain in the ass her grown son is and does not tolerate or coddle him when he acts up.
• Meaningful Name: Say his name repeatedly and quickly and you'll discover why the name is perfect for him.
• Money Dumb: He doesn't have a job due to being too lazy and unwilling to stop living off his mother, but he still wastes a lot of money on unnecessarily expensive tabs at the Krusty Krab and personal pleasures like toys and cardboard for his personal Three Deadly Challenges set.
• Occidental Otaku: The Patrick Star Show episode "Bubble Bass Reviews" reveals that Bubble Bass has a bit of an interest in anime catgirls, as he has a wallpaper depicting one named Kitten Princess on his computer and at one point a clip of him wearing Kitten Princess cosplay is shown.
• Overcomplicated Menu Order: Due to his Big Eater habits, Bubble Bass tends to make his orders at the Krusty Krab way more complicated than necessary. In "Larry the Floor Manager," he even takes so long to place his order that he ends up driving customers away, prompting Mr. Krabs to shove a patty down his throat and tell him to just buy a regular Krabby Patty.
• Pet the Dog:
  • In "Plankton's Good Eye", he thanks Plankton for rescuing him, and when Plankton is given a surprise party for all the good deeds he's done, Bubble Bass is among the people at the party.
  • In "SpongeBob's Big Birthday Blowout", he helps set up SpongeBob's surprise birthday party.
  • In "Sea-Man Sponge Hater’s Club" he’s a respectful member of the club who listens to the others’ stories with genuine sympathy. Heck, joining the club in general is this considering that the club creed is that they don’t actually want something bad to happen to SpongeBob.
• Remember the New Guy?: Kind of; in his first appearance it's made clear he and SpongeBob have an antagonistic history.
• Rogues' Gallery Transplant: He has made crossover appearances in The Patrick Star Show, most notably "Bubble Bass Reviews" where he becomes Patrick's Caustic Critic.
• Seven Deadly Sins: Unsurprisingly, Bubble Bass shows all seven of them throughout his appearances.
  • Pride: Bubble Bass is a very smug and condescending person who believes himself superior to others and rarely admits his wrongs...if ever. Despite Bubble Bass's perceived superiority over others, he's ultimately a pathetic, lazy and cowardly loser with nothing to boast about it, not that it stops him. Due to this, Bubble Bass never learns from his mistakes even when he suffers the consequences of his actions, such as in 'Bubble Bass's Tab' when him amassing such a huge tab got him in trouble and he had to work at the Krusty Krab to pay it off. Even after the patrons paid off Bubble Bass's tab, he immediately opened a new one.
  • Lust: Bubble Bass is an unrepentant hedonist, only caring about indulging in his personal pleasures of eating food, recklessly spending his money on toys, and spiting people for fun.
  • Greed: Bubble Bass is very irresponsible in terms of money, choosing to spend it on large amounts of cardboard for his Three Deadly Challenges set as well as toys and comics. The stuff Bubble Bass spends his money is on is ultimately pointless as it does nothing to help him improve his life and only fuels his immature lifestyle.
  • Sloth: Bubble Bass is extremely lazy, choosing instead to indulge in his vices and immature behavior rather than work to improve his life. He is unrepentant in his hedonism, shows no concern for the concepts of right and wrong as he prioritizes his personal pleasures above all else, and shows complete apathy towards work of any kind since he refuses to look for a job. In 'Bubble Bass's Tab', after he loses the Three Deadly Challenges and has to work off his massive tab, he barely puts any effort into his job. Heck, he cleans the dishes with a TOILET!
  • Wrath: Bubble Bass can get very angry when his mother interrupts his activities and tried to move out simply because she wanted him to do chores. He also tends to throw fits when his very complicated and picky orders aren't done precisely the way he wants them.
  • Gluttony: Bubble Bass loves to gorge himself on huge quantities of fast food. In one episode, Bubble Bass considers a 'light snack' to be a big bucket of Krabby Patties, three large orders of fries, a hot dog and a large soda. He's also excessively picky as his orders are extremely complicated and he'll throw a fit when it's not done precisely the way he wants it.
  • Envy: It's implied several times that despite his condescending behavior, Bubble Bass is jealous of SpongeBob for his successes (having his own home, working a full time job, being rather popular with the people of Bikini Bottom (barring a few for obvious reasons)). Due to his spiteful personality, he takes pleasure in the suffering of others, most proven in 'Pickles' when he ruined SpongeBob's mental health and self-confidence simply for his own entertainment.
• Small Name, Big Ego: Bubble Bass is generally a smug, rude and condescending person who loves to behave as though he's superior to everyone...except he's a Basement-Dweller who's too lazy to get a job, has no friends in his life due to his unpleasant personality, lacks any accomplishments that he can be proud of, and does nothing to achieve his desires of becoming a TV Star. Bubble Bass loves to talk a big game, but when it matters, he has nothing he can boast about.
• Smug Snake: He's quite full of himself, but at the end of his debut, it turns out he's been using dirty tactics to mess with SpongeBob. When he's found out and confronted for it, he immediately runs off. This carries on in his other appearances, as he usually acts smug and wicked when he has the upper hand, but the moment he begins suffering consequences, he's reduced to a crying wreck.
• Species Surname: He's a sea bass named Bubble Bass.
• Stereotypical Nerd: In addition to wearing glasses, having a large amount of weight, and being unusually knowledgeable in Hash House Lingo and food preperation in general, later seasons would characterize Bubble Bass as a geek who lives in his mother's basement, keeps collectibles in their packaging, and is obsessed with comic books and role-playing games. The Patrick Star Show takes this further by having him state that the Shell City Comic Convention is the only holiday he celebrates in one episode and hosting an online review show similar to Caustic Critics such as The Nostalgia Critic and The Mysterious Mr. Enter in another episode.
• Stout Strength: Despite his obesity, he's strong enough to effortlessly push away an entire crowd of people and fling Squidward around like a toy.
• Thin-Skinned Bully: In his first appearance he's smug and sadistic until he's been foiled, after which he pathetically runs for his life in shame. In later appearances, while he doesn't go out of his way to bully people as often as he did in "Pickles", he's still happy to push people around and make them miserable until they inevitably gain the upper hand, and then he's reduced to a cowering wreck.
• Took a Level in Kindness: He's not as outright sadistic as he was in the first season in his later appearances, and doesn't go out of his way to make SpongeBob's life miserable in particular. He's still very unpleasant and unlikable, however.
• Trademark Favorite Food: Krabby Patties, especially with pickles.
• Trrrilling Rrrs: Bubble Bass sometimes has a tendency to roll his R's when he's hamming it up.
  Bubble Bass: How about a game of Thrrree Deadly Challenges?
• Unsatisfiable Customer: Type 4, since he was making false complaints for SpongeBob's flawless service, either for a free Krabby Patty or just to Mind Screw SpongeBob For the Lulz.
• Villainous Glutton: In the later seasons he is usually seen ordering extremely large amounts of food such as quadruple burgers, and even his iconic first order from "Pickles" was deciphered by fans to be a 24-Patty sandwich. Bubble Bass' appetite is only matched by his tremendous size, a clear consequence of such a diet. In "Sea-Man Sponge Haters' Club", he is outright giggling with delight once he gets to eat something from his order, and is even happy once SpongeBob forced himself down into his belly, suggesting he wouldn't have minded if the fully grown adult sponge had stayed there.
• Vitriolic Best Buds: "BassWard" implies he and Squidward are on their way to becoming this after surviving their trip gone wrong together. The end of the episode amiably telling each other they hate each other.
• Wicked Cultured: As gluttonous as he is, he is genuinely well-versed in food preparation and is a veritable encyclopedia of kitchen lingo and ingredients. His later characterization as a stereotypical nerd also lines up as he is shown to be highly knowledgeable of pop culture (such as comic books, role-playing games, etc.).
• You Are Fat: Downplayed in Season 1, as he only receives one crack about his weight, but his huge size is usually portrayed as being for laughs. In later seasons, his obesity, huge appetite, and poor shape start serving more as a source of physical comedy.

Fred

Fred

"My leg!"

Voiced by: Various (primarily Mr. Lawrence)
Debut: "Reef Blower"

An accident-prone fish seen in various episodes to say his famous catchphrase after something bad happens to him. This character model's name has varied; in most appearances from seasons 1 to 10, he was nameless, with the exception of "Patty Hype" in which he is called Fred in a 2-second throwaway line. His name was given as Clint in "Big Sister Sam" from season 7. In season 10, the new showrunners re-adopted the name Fred after seeing it on fan-made wikis, mistaking it for a fan-created name.

---

• Ascended Extra: Originally just a background character, Fred rose to prominence in "My Leg!", which was all about him. Since then, Fred has not been forgotten as he's made plenty of supporting roles in future episodes, not as a background character, but as just another member of the recurring cast. He'd still be referred to by name, he'd have meaningful interactions and relationships with the other characters, and he was just one of the guys.
• Borrowed Catchphrase: Before Fred officially became the designated "My Leg" guy in Season 11, earlier episodes would feature other background characters getting hurt and saying "MY LEG!".
• Breakout Character: Easily one of the most popular minor characters of the series thanks to his hilarious Butt-Monkey status and tons of his dialogue becoming memes such as "Rev Up Those Fryers", "DEUAAAAAUGH", and of course, "MY LEG!".
• Character Catchphrase: Fred often says "my leg!" whenever gets injured.
• Chuck Cunningham Syndrome: Ever since Fred was officially turned into a consistent supporting character, his blue and brown palette swaps completely stopped appearing.
• A Day in the Limelight: He is focused on in the episode appropriately titled "My Leg!".
• Early-Installment Weirdness: Due to originally being a background character, with no set in stone role or personality, there are multiple episodes of the show, depicting Fred as someone he's not. Certain episodes show him as being a married man, others depict him as a farmer, in some episodes, he's an old man, others give him a British accent and many episodes depict him as being blue, purple, or brown. And in "No Nose Knows" alone, he actually becomes female for one scene, before going back to male in a later scene.
• Frozen Face: In "Face Freeze", Fred kept sticking his tongue out at random people on the streets, just to be rude. Eventually, he did this too many times, 444 times to be exact, which led to his face freezing that way.
• Half-Dressed Cartoon Animal: Typically wears a pair of pants but no shirt.
• Hidden Depths: If the episodes like "Jellyfish Hunter" and "My Leg!" are any indication, Fred appear to be quite a talented singer.
• Inconsistent Coloring: He is in both brown and blue versions. There is also a brown-green version used only once, in "Professor Squidward".
• Jerkass Ball: In "Face Freeze", Fred walked around Bikini Bottom, sticking his tongue out at everyone he saw.
• Jerk with a Heart of Gold: Quite a few episodes show him as a rude and antagonistic character, but like the other incidentals, he really isn't a bad person.
• Love Makes You Dumb: It was revealed in "My Leg!" that he's been purposefully breaking his leg because he's in love with Nurse Daisy Bazooka, a nurse who works at the hospital, and breaking his leg is the only way to get close to her.
• No Indoor Voice: He yells quite a lot of his dialogue.
• Ow, My Body Part!: He's constantly heard yelling "MY LEG!!!", even when it is not even his leg being put through harm.
• Out of Focus: Due to the fact he is a minor character, he usually rarely plays a major role.
• Running Gag: The infamous "MY LEG!" gag, where whenever there's a huge accident in the show, you can always hear somebody say "MY LEG!" That somebody would later turn out to be Fred.
• Self-Harm: It was revealed in "My Leg!" that Fred willfully injures his leg on purpose because he's in love with the nurse and whenever he goes to the hospital for his broken leg, he gets to see her.
• They Killed Kenny Again: Played With. He doesn't "die", but whenever he shows up you can expect him to get horribly injured and scream... do we really have to say it?
• Uncle Pennybags: In "One Krabs' Trash", Fred was an eccentric billionaire who bid one million dollars on Mr. Krabs' soda hat.

Old Man Jenkins

Old Man Jenkins

"Respect your elders!"

Voiced by: John Gegenhuber (standard voice), Dee Bradley Baker (secondary voice), Mr. Lawrence ("Sailor Mouth"), Tom Kenny ("My Pretty Seahorse")
Debut: "Your Shoe's Untied"

A ridiculously old man, who owns a farm.

---

• Ascended Extra: Although he was initially just a character who would make recurring gag appearances, he's overtime become somewhat of a breakout character, who's now being given notable roles in multiple episodes.
• Barefoot Loon: Old Man Jenkins doesn't wear shoes, even when he goes to restaurants.
• Beware the Silly Ones: Old Man Jenkins may seem like a harmless old goat, but he can drive other people crazy with his annoying old man powers and being a senior, he's pretty much societally immune to any adult younger than him disrespecting him back because you know, "Respect Your Elders".
• Breakout Character: Originally, the name "Old Man Jenkins" was just a name given to every single senior citizen around Bikini Bottom, which would be used whenever a gag involving an old man came into play. However, these old men all became really popular with fans to the point, where they wanted to see at least one of the Old Man Jenkinses to become a character. The writers recognized this and thus began the birth of the recurring old farmer guy, we now know as the official "Old Man Jenkins".
• Cool Old Guy: The most notable example would be in "The Sponge Who Could Fly", where he ends up becoming a human (well, fish) cannonball.
• Deep South: As an old farmer dude, he's obviously going to play into a few of these tropes.
• Early-Installment Weirdness: Before the creators officially settled on what they want Old Man Jenkins' actual appearance to look like, earlier episodes of the show (from seasons 1 to 4) have given that name to random senior citizens in Bikini Bottom that don't look or act a thing like him.
  • In fact, some episodes even feature the character model that now officially belongs to Old Man Walker and address him as Old Man Jenkins.
• Farm Boy: Old Man Jenkins is a committed farmer, who raises a bunch of undersea livestock.
• Friend to All Living Things: Old Man Jenkins is a kindly old man, who is friends with just about everyone else in Bikini Bottom and as a farmer, Old Man Jenkins is friendly with all of the animals, he raises on his farm. Additionally, in "FarmerBob", Old Man Jenkins became friends with some hillbilly aliens, meaning that he has friends with creatures all across the universe.
• Genius Ditz: Old Man Jenkins may be a complete buffoon, but he sure knows how to run his farm.
• Recurring Extra: He tends to appear as a bit character.
• Nice Guy: Although some episodes contradict this ("ahem, 'Senior Discount', cough cough.") Old Man Jenkins is a goofy, but a kind-hearted guy, who can make easy friendships with everyone he meets.
• Screw Politeness, I'm a Senior!: Took this to absolute extremes in "Senior Discount", when he started being blatantly disrespectful at the Krusty Krab just for the sake of being rude. Whenever Mr. Krabs tried to do anything about it, Old Man Jenkins would just remind him to "respect his elders".
• You Don't Look Like You: His appearance isn't usually consistent. Justified because there might be more than one Old Man Jenkins. It seems that as of recently, the animators have finally made up their minds and settled on making Old Man Jenkins a green farmer fish with a long, scraggly gray beard, who wears a straw hat and dirty worn-out old overalls.

Old Man Walker

Old Man Walker

Whuh? Wha... Where am I?

Voiced by: Tom Kenny
Debut: "Mermaid Man and Barnacle Boy"

A confused and discombobulated old man, whose naivety gets him kicked around by the world.

---

• Ascended Extra: Originally appearing as just a background character, Old Man Walker has now started having more supporting roles in certain episodes.
• Blind Without 'Em: Actually, he's still pretty blind with 'em too. As seen in "As Seen on TV", Old Man Walker sees SpongeBob and tells him "I saw you on TV last night.", only for a flashback to reveal that Old Man Walker was actually just watching a commercial with a yellow cereal box.
• Butt-Monkey: Old Man Walker is occasionally the victim of physical violence and slapstick gags.
• Cloudcuckoolander: Old Man Walker seems to be suffering from dementia, causing him to act rather buffoonish and make various non-sequitur comments, whenever he's on screen.
• The Ditz: Old Man Walker is rather dopey.
• Early-Installment Weirdness: Before the creators settled on making him the dim-green colored old man with the raspy and arid voice he has now, earlier episodes have depicted him as being different colors or having completely different voices that in no way reflect the Old Man Walker we know today. To add to the confusion, certain episodes address him as "Old Man Jenkins", which is a name that currently belongs to a completely different character, so... have fun trying to figure that one out.
• Elder Abuse: The people of bikini bottom don't exactly know how to respect their elders.
• Hollywood Tone-Deaf: In "Sing a Song of Patrick", he was the only character who liked Patrick's horrible music.
  Old Man Walker: I like it!
• The Pawn: Other characters tend to use Old Man Walker as an object and make him to tasks and jobs without him asking. Being the happy-go-lucky man he is, Walker just casually goes along with it, no matter how weird, insulting, or painful it is. For instance, in "SpongeBob's Big Birthday Blowout", Mr. Krabs forced Old Man Jenkins to serve as the lookout while the rest of the more important characters, did the important stuff to set up for SpongeBob's party. Or as an even worse example, "Call the Cops", the police labeled Walker as "evidence" instead of a "witness" or a "victim" and had him locked away in the evidence locker like he was an inanimate object.
• Punny Name: Well, more of a play on words. His name is a joke on old man walkers, which are walkers used by senior citizens to help them move.
• You Don't Look Like You: As a background character, Old Man Walker has gone through a number of changes in his physical appearance.

Squilliam Fancyson

Squilliam Fancyson

"Come on everyone: let's go take a ride in my balloon/casino!"

Voiced by: Dee Bradley Baker
Debut: "Band Geeks"

Squidward's rival from high school. Squilliam is essentially everything Squidward dreamed of being. Whereas Squidward is a middle-class jackass stuck in a dead end job and considered a joke by everyone except SpongeBob and Patrick, Squilliam is a successful, filthy stinking rich jackass beloved by all. Also, unlike Squidward, who has had a few Pet the Dog moments over the years, he appears to have no redeeming qualities whatsoever. He loves rubbing his success in Squidward's face.

---

• The Ace: Is way more successful compared to Squidward.
• Always Someone Better: He's far more successful than Squidward ever was or will ever hope to be.
• The Bad Guy Wins: Won in "Squilliam Returns" (where Squidward's attempt to get back at Squilliam by disguising the Krusty Krab as a five-star restaurant fails) and "Professor Squidward" (where Squidward is mistaken for Squilliam and took advantage of it until he was unmasked and arrested while the real Squilliam smugly watched), but normally his appearances are a sign Squidward will win this one—or, at the very least, not have to suffer his usual misfortunes alone.
• Big Jerk on Campus: Apart from the fact that he's not a highschooler, he fits this trope to a T because of his arrogance and looking down on everyone else, ESPECIALLY Squidward.
• Big Ol' Unibrow: He has a noticeable unibrow.
• Born Lucky: He turned out to be lucky and successful, making him the Gladstone Gander to Squidward's Donald Duck.
• Chuck Cunningham Syndrome: Essentially vanished from the series after a background appearance in season 7's "Back to the Past", barring a brief reference in "Code Yellow". Vincent Waller has also revealed in two tweets from 2019 and 2022 respectively that there are no plans to bring Squilliam back as a recurring character for Seasons 12 or 13, Kamp Koral, or The Patrick Star Show, but he has made small cameos in Bikini Bottom Inquirer.
• Dub Name Change:
  • Siegbert Schnösel in the German dub.
  • Hjalmar von Kalmari in the Finnish dub.
  • Octavius Bläckenberg in the Swedish dub.
  • Squilli Elegant in the Italian dub.
  • Calamarino Elegante in the Latin-American dub.
• Evil Counterpart: Though neither are exactly evil, he's this to Squidward. Take Squidward, add some Smug Snake and several levels in jerkassitude, and remove any redeeming qualities. That's Squilliam.
• Fatal Flaw: Pride. Squilliam would be a clear success story over Squidward, if he could resist rubbing it in his face and trying to humiliate him even further. A lot of these instances end with Squidward actually getting a rare moment of glory and upstaging Squilliam for once.
• Half-Dressed Cartoon Animal: Wears a robe but no pants.
• Hate Sink: Squilliam has virtually no sympathetic qualities about him, making it all the easier for one to root for the normally jerkassy Squidward.
• Hoist by His Own Petard: It's heavily implied that he set the entire situation in "Band Geeks" up to humiliate Squidward, which makes the success even more deliciously ironic.
• Humiliation Conga: In the iconic scene of "Band Geeks", where he has a heart attack at how good Squidward's band is and is carried away on a stretcher. Gets another one at the end of "House Fancy", where he cries his eyes out over Squidward's home being deemed fancier than his.
• Jerkass: Mean, selfish, arrogant and takes great delight in rubbing his wealth and success in everyone's faces. It seems all members of his species are jerks.
• Jerkass to One: For how much Squilliam likes to brag about his wealth and success, he takes much more delight in rubbing it in Squidward's face, since he knows that he is everything Squidward dreams to be, but Squidward is stuck as a cashier with a horrible salary.
• Jerk with a Heart of Jerk: Squilliam treats his friends well, though it's most likely to show off his wealth. The episode "Squilliam Returns" has him treat his friends to dinner, though they can't really eat because it's so expensive, and feign sympathy towards Squidward when he admits that he's just a cashier, ultimately rubbing his success in his face by joking that his wealth is fake and that he's also a cashier.
• Lean and Mean: He's very skinny and even more of a jerk than Squidward.
• Narcissist: Ironically, one of the only things he has in common with Squidward (and possibly with every member of their species, going off of episodes like "Squidville") is how self-loving he is.
• Nice to the Waiter: For all of his intolerable dickery and arrogance, Squilliam is sincerely impressed with SpongeBob's fancy service in "Squilliam Returns" and singles him out as the most impressive part of Squidward's "fancy restaurant", complimenting SpongeBob and even trying to get his name. He hadn't counted on that being the thing to send SpongeBob out of control, though.
• Non-Indicative Name: Just like Squidward, Squilliam is not actually a squid, but an octopus.
• Put on a Bus: Since his last official appearance more than a decade ago in "Blast to the Past", ^note (not counting a brief cameo in "Code Yellow" as one of Squidward's noses) he has yet to make a return to the series. Vincent Waller has stated that there are currently no plans to feature him in any Spongebob media aside from possible background cameos in the future.
• Politically Correct Villain: Squilliam has friends (or at least admirers) of various species, and seems unbiased about SpongeBob and Patrick being a Sponge and a Starfish unlike the Octopuses seen in Squidville.
• Rich Bastard: He has a private jet, private yacht, private airship, private casino, etc..
• The Rival: He is Squidward's rival.
• Smug Snake: He never misses a chance to rub his success in Squidward's face. True to this trope however, some of his worst attempts to kick Squidward while he's already down backfire on him horribly.
• Villainous Breakdown: At the end of "Band Geeks", seeing Squidward completely succeed in an absolutely epic way causes him to have a heart attack! Has another one at the end of "House Fancy" where Squidward's house being declared even fancier than his leaves Squilliam laying on the ground crying his eyes out.
• Wealth's in a Name: Fancyson, fitting for a rich jerk.

Marina

Voiced by: Jill Talley
Debut: "Mall Girl Pearl"

Pearl's friend, who works at the mall restaurant, Hot Dog on a String.

---

• Bad Job, Worse Uniform: Marina works as a hot dog vendor in the mall and has to wear a bucket full of weiners on her head.
• Navel Window: Marina shows off her bellybutton. Even Marina's work uniform shows this.
• Punny Name: Her name is a pun on "Maria" and it's a reference to the fact that as a sea creature, she is a "Marine" life form.
• With Friends Like These...: Despite being Pearl's friend, Marina makes fun of her if she does anything lame.

Nocturna

Voiced by: Aubrey Plaza
Debut: "Mall Girl Pearl"

Pearl's friend, who is your typical goth girl. She works at a clothing store at the mall called Scorched Coral.

---

• Blank Stare: Her standard facial expression.
• Deadpan Snarker: Nocturna makes a lot of snarky sarcastic comments. Most of them are really dark and miserable.
• Goth: Nocturna is goth.
• Meaningful Name: "Nocturna" is derived from the word "Nocturnal", which relates to the night. The night is dark and Nocturna is dark.
• Perpetual Frowner: As a goth, Nocturna never really has too many moments, where she cracks a smile.
• Sadist: Nocturna gets a good laugh out of watching people suffer.
• The Stoic: She was the only one who didn't visibly cringe in terror, upon seeing Squidward's mutilated body in "Whale Watching".

Nixie

Voiced by: Sirena Irwin
Debut: "Mall Girl Pearl"

Yet another of Pearl's friends, and a very cheery one at that. She works at Bangles and Dangles, the jewelry store at the mall.

---

• Cheery Pink: Nixie's bright and chipper personality is matched by her hair color, which is a very vibrant shade of hot pink.
• Everything's Sparkly with Jewelry: Nixie works at the jewelry store, Bangles and Dangles, so she pretty much surrounded by bright and flashy jewelry all the time.
• Genki Girl: Nixie is extremely happy all the time.
• Pubescent Braces: One of Nixie's most notable physical traits is her large, flashy braces.
• Sweet Tooth: Nixie has a sweet brace-covered tooth when it comes to ice cream. In "The Goofy Newbie", she was a customer at Goofy Goober's Ice Cream Party Boat.

Rube

"AMAZING!"

Voiced by: Mr. Lawrence
Debut: "No Pictures, Please"

A perpetually-happy tourist who mistook Patrick for a tour guide. Although he initially appeared to be an illusion created by the Tidal Zone, later episodes confirm him to be a living being.

---

• Ascended Extra: After appearing as a minor recurring character in several season 12 episodes, he takes on a larger role as the main character of "No Pictures Please" as well as being SpongeBob and Patrick's tour guide to the surface world in "SpongeBob's Big Birthday Blowout".
• Big Fun: A sizable fish who's tons of fun to be around.
• Camera Fiend: Drives everyone crazy by constantly taking pictures of people.
• Character Catchphrase: "Amazing!"
• Characterization Marches On: He was initially presented as completely absent-minded and not respectful of people's privacy, not to mention being implied to have been an illusion. When he's reintroduced as a real person, Rube still keeps his cloudcuckoolander nature, referring to things on the surface with incredibly bizarre names, but is much more willing to take initiative with the rules of the bus, as well as being respectful of the fact that it's SpongeBob's birthday.
• The Ditz: Is stupid enough to mistake Patrick for a tour guide and gets into a number of comedic shenanigans with him as a result.
• Keet: Almost always in a chipper mood.
• The Klutz: While trying to sing SpongeBob's birthday song, his big butt slammed into the bus lever, causing the bus to take off, full speed ahead, sending him miles away from SpongeBob's house.
  SpongeBob: It's okay, maybe next year!
• Mundane Object Amazement: Rube will find just about anything to be amazing and worthy of being photographed.
• Perpetual Smiler: Keeps a huge smile on his face no matter the situation.

Dr. Gill Gilliam

Dr. Gill Gilliam

"Uh, yeah. We're from the pet hospital down the street and I understand you have a dying animal on the premises."

Voiced by: Rodger Bumpass, Dee Bradley Baker ("The Two Faces of Squidward")
Debut: "I Was a Teenage Gary"

Bikini Bottom's resident doctor.

---

• Alliterative Name: Gill Gilliam, revealed in "Once Bitten".
• Back-Alley Doctor: Some episodes portray him as being incompetent at his job, such as "I Was a Teenage Gary", where he was "too squeamish" to inject Gary with snail plasma.
• New Job as the Plot Demands: Not only has he practiced in numerous fields of medicine, but he's also shown in one episode as a pirate.
• Palette Swap: The recurring doctor is purple, but he appears orange as Gil Gillian, leaving uncertainty as to whether or not they are the same character, though other palette swaps, such as Perch Perkins, seem to be considered the same.
• Super Doc: He's a general practitioner, a surgeon, an obstetrician, a dentist, and a veterinarian.
• Took a Level in Cynic: He becomes less cheerful as the series goes on. Probably because of SpongeBob and the main casts' antics that caused a lot of trouble.

Lady Upturn CCCXXXIII

Lady Mildred Upturn CCCXXXIII

"Walk... AROUND!? Hmmph! I am Lady Upturn the 333rd and you want me to WALK AROUND!?

Voiced by: Lori Alan
Debut: "Krusty Katering"

A fancy rich lady, who thinks she's better than everyone else.

---

• Beauty Is Never Tarnished: Lady Upturn gets crapped on a lot by the world and all of her fancy dresses and hairdos are constantly getting ruined but she's usually good at quickly fixing herself back up again and putting everything back to normal... usually.
• Butt-Monkey: Since she's so fancy and everything has to be perfectly in place for her, it's only logical that in typical SpongeBob fashion, everything has to go horribly wrong for her in ways that completely destroy all of her fanciness in the most hilarious and stupid way possible.
• Catchphrase: "I am offended!"
• Cultural Stereotypes: Lady Upturn talks and behaves like a stereotypical Englishwoman, in that she acts very snobbish and condescending to others and expects to be treated like royalty just for existing. She also seems to come from an extensive noble family, as she has the title of "Lady" (and is apparently the 333rd of her kind).
• Narcissist: Lady Upturn thinks so highly of herself, that she feels as though the world should revolve around her. In "Moving Bubble Bass", she got offended at the very notion that she, the fabulous and well-beloved Lady Upturn the 333rd, should have to (gasp!) WALK AROUND SpongeBob and Patrick, when they crossed paths with her.
• Nice to the Waiter: Lady Upturn may be a jerk, but she's more than polite to her servers at restaurants, paying them tons of money for doing menial tasks for her. This has, of course, led to her becoming a number one customer for Mr. Krabs.
• Overly Long Name: Full name: Lady Mildred Upturn the Three-Hundred and Thirty-Third.
• Proud Beauty: Lady Upturn really thinks she's a gorgeous lady.
• Rich Bitch: Lady Upturn is extremely snooty and snobbish and treats other people like garbage.
• Uncatty Resemblance: Lady Upturn's pet worm has a big fancy blonde hairdo just like she does.
• Uncle Pennybags: Lady Upturn is loaded with cash, which makes her a very beloved customer of Mr. Krabs. In "Krusty Katering", she paid Mr. Krabs $50,000 in advance just for catering at her party.

Helen the Felon

Helen the Felon

Hey, you mugs! It's a jailbreak! Let's am-scray!

Voiced by: Sirena Irwin ("Call the Cops"), Carolyn Lawrence ("Escape from Beneath Glove World")
Debut: "Call the Cops"

A little girl with a criminal record.

---

• Beware the Cute Ones: She may be cute, but she's bad to the bone.
• Bitch in Sheep's Clothing: Helen looks and acts like a nice little girl but she's actually an evil villain, who's known for being Bikini Bottom's most wanted criminal.
• Enfant Terrible: Despite being a little girl, Helen has gotten herself sent to jail multiple times and for good reason too. She's wanted for various crimes of all sorts from assault to theft to selling girl scout cookies without a license.
• Even Evil Has Standards: In "Escape From Beneath Glove World", Helen says that she got arrested for murdering a guy. She follows this by admitting she was only joking and that her real reason for getting arrested was because she bit the guy running the lemonade stand.
• Girl Scouts Are Evil: In "Call the Cops", she sold girl scout cookies without a license.
• Girlish Pigtails: She has blonde pigtails.

Families and pets

SpongeBob's family and pets

Harold and Margaret SquarePants

Harold and Margaret SquarePants

Voiced by: Tom Kenny and Sirena Irwin
Debut: "Home Sweet Pineapple"

SpongeBob's parents.

---

• Crazy Jealous Guy: In "New Digs", Mr. Krabs pulls down a shower curtain that Margaret is behind, thinking that it was SpongeBob, she shrieks and he apologizes repeatedly and backs off, but Harold doesn't take this well.
• Given Name Reveal: "Whelk Attack" reveals that Margaret's maiden name is "BubbleBottom".
• Good Parents: They really adore their son, even allowing him to stay at their place after he loses his home, and buying him a boatmobile after he gets his driver's license.
• Happily Married: They are always seen together and seem really happy with each other.
• Innocent Blue Eyes: Margaret has a pair, which is where SpongeBob gets his.
• Nice Guy: They're both kind and well-mannered. It's easy to see where SpongeBob got his kindhearted nature from.
• Parental Obliviousness: They don't seem to realize how much of a sociopath Blackjack is or how much pain and torment he used to cause their son.
• The Pollyanna: Margaret is usually seen being cheerful and optimistic about everything, especially when compared to her husband, which is where SpongeBob probably gets it from.
• Shared Family Quirks: The book Hooray For Dads shows that SpongeBob gets his jellyfishing skills from Harold.
• So Proud of You: At the end of "Culture Shock" after SpongeBob gets a standing ovation from the audience.
• Youthful Freckles: Margaret has them, which SpongeBob inherited.

Grandma SquarePants

Grandma SquarePants

Voiced by: Marion Ross
Debut: "Grandma's Kisses"

---

• The Bus Came Back: After 12 years of absence, she finally returns in Season 14’s “Don’t Make Me Laugh” with Marion Ross reprising her role.
• Chuck Cunningham Syndrome: She hasn't had a single physical appearance since Season 8 in "Pet Sitter Pat" and hasn't been mentioned since Season 11's "Squid Noir". Marion Ross has since retired from acting, meaning she's unlikely to return.
• Cool Old Lady: In the comic "Great Grandma", she's not only a Supreme Chef, but she's a modern dance aficionado, she collects rare clarinet records, and she's a talented painter who is also skilled at making homemade paint.
• Covered in Kisses: SpongeBob gets covered with kissing marks by her on an implied regular basis.
• Hidden Depths: The comic "Great Grandma" reveals that she and Squidward have a lot of the same cultural tastes. She's even into modern dance! He's pleasantly surprised by every aspect of this and forgets his promise to not have anything to do with her immediately after.
• Put on a Bus: After her actress retired from acting, Grandma was relegated to non-speaking cameos and background appearances.
• Supreme Chef: SpongeBob loves her cookies. In "Great Grandma", she offers to teach Squidward to make coral quiche with seaweed butter; later in the comic he stops by her house to smell her kelp casserole with extra kelp.

Shelley

Shelley

Voiced by: N/A
Debut: "Help Wanted"

SpongeBob's pet scallop, who lives in a cage in his bedroom.

---

• All There in the Manual: Her name and gender are only revealed in the "Bikini Bottom's Up Tour", a special feature on Disc 3 of The Complete 1st Season DVD. When the viewer selects her cage, Patchy talks about her and says that her name is Shelley while also confirming she's a female.
• Birdcaged: Shelley lives her entire life in her cage and has only been proven by absence to escape twice. In "The SpongeBob Movie: Sponge Out of Water", Shelley cage was empty and there was a big hole in it and "SpongeBob's Place", her cage was full of money and she was not present.
• Forgettable Character: Episodes such as "A Pal for Gary" and "Rock-A-Bye Bivalve" seem to completely deny the existence of Shelley, even though she is physically seen in background shots of those very episodes.
• Living Prop: Shelley has only appeared in the background of scenes taking place in SpongeBob's room. Not once has she spoken, moved, or even been acknowledged by the rest of the cast. Her existence has only ever been acknowledged twice in the franchise, once in the "Bikini Bottom's Up Tour", a special feature on Disc 3 of The Complete 1st Season DVD, which is where her name and gender are confirmed, and once in the PC version of The Sponge Bob Movie Game, where her empty cage can be examined and SpongeBob will comment that his pet escaped, while not naming her and incorrectly referring to her as a male and a clam instead of a scallop.
• Minor Major Character: Major emphasis on "Minor". Shelley has been around since day one, as she appeared in the first episode and his very closely linked to the main cast, being the pet scallop of SpongeBob SquarePants, himself, and yet, she hasn't had a single episode about her, line of dialogue, or even moment in the series wherein she moves or is directly acknowledged by any character of the series.
• Out of Focus: Shelley is woefully underrepresented in the SpongeBob canon, as she currently exists as nothing more than a motionless prop, sitting silently in the background, doing nothing throughout the entire series.
• Punny Name: Her name is a pun on the fact that as a scallop, she is a shell.
• The Voiceless: She has not spoken once in the series, although following the rules of animal species in the SpongeBob universe, it's likely that as a scallop, Shelley would only chirp like a bird.

Patrick's family and pets

Mr. and Mrs. Star

Herb: Wow, son, you recognized us this time!
Margie: And you remembered to get dressed today.^note From left to right: Margie and Herb.

Voiced by: Thomas F. Wilson (Herb and Cecil), Susan Boyajian (Margie), Cree Summer (Bunny)
Debut: "I'm With Stupid" (Herb and Margie) "The Patrick Star Show" (Cecil and Bunny)

Patrick's parents.

---

• Adaptation Name Change: They are known as Herb and Margie in the main show, but in Patrick's spinoff, they are renamed Cecil and Bunny.
• Amazing Technicolor Population: In The Patrick Star Show, Cecil is blue-green while Bunny is purple.
• The Cameo: They reappear in "Rule of Dumb" on Patrick and Gary's family tree as well as "Patrick's Tantrum".
• Composite Character: The designs of Patrick's parents in The Patrick Star Show borrow elements from both Patrick's fake parents and real parents from "I'm With Stupid".
• Cruel to Be Kind: In "Home Sweet Pineapple", Patrick mentions that they got tired of him and kicked him out of the house so he could learn to live by himself.
• Like Parent, Like Child: "I'm With Stupid" happens not only because Patrick thought two strangers were his parents, but because Herb and Margie got lost on their way to Patrick's house and kept bothering his neighbor Squidward about where their son is. On the other hand, they're amazed that Patrick recognizes them at the end and that he remembered to get dressed.
• Retcon: Due to SpongeBob's loose continuity, Patrick's parents in The Patrick Star Show are replaced by two new characters, Cecil and Bunny.
• Shout-Out: Patrick's mistaken parents, Marty and Janet, are visually and vocally based on Homer and Marge from The Simpsons. The names of Patrick's real parents, Herb and Margie, are also based on Homer and Marge's names.

Squidina Star

"No one beats the nerd out of Squidina!"

Voiced by: Jill Talley
Debut: "Goons on the Moon"

A member of the Science Scout troop who goes with Sandy to the moon. She is shown to have a bit of a rivalry with Pearl, as the two tease each other over their choice in social cliques. Doubles as a both a science-loving nerd and a comic book-loving geek who loves playing with action figures too much. She's a main character in the spin-off The Patrick Star Show, as Patrick's younger sister and the executive producer of his talk show.

---

• Alliterative Name: Squidina Star.
• Animal Jingoism: She's a squid who has a small rivalry with Pearl, a sperm whale.
• Animals Not to Scale: She's implied to be a Giant Squid based on her head shape and relationship with Pearl, yet stands shorter than a squirrel (at least at eye level). To make things more confusing, her head fins also technically make her taller than Squidward, a fully-grown cephalopod, despite being a kid.
• Ascended Extra: Squidina had only made two appearances in SpongeBob SquarePants (one supporting, one minor) prior to The Patrick Star Show, which made her the deuteragonist.
• Bad Job, Worse Uniform: In "The Goofy Newbie", Squidina worked at the Goofy Goober store, serving people ice cream, while wearing a giant peanut outfit.
• Bizarre Alien Limbs: Her tentacles frequently alternate as arms and legs, often to the point where she can walk around with four legs and two arms in one moment, and two legs and four arms in another. Justified, since she is a squid after all.
• Breakout Character: Squidina was initially introduced in "Goons on the Moon" as a supporting character who served as a rival for Pearl. Squidina proved popular enough with fans that she made a small cameo in "The Goofy Newbie" before becoming a main character in The Patrick Star Show, where she has just as much prominence as Patrick. She also has the honor of being one of the first spinoff characters to appear in a Nickelodeon crossover game, appearing in the third Nickelodeon Kart Racers game as a playable racer.
• Connected All Along: The Patrick Star Show lightly retcons her as Patrick's younger adopted sister.
• Cool Kid-and-Loser Friendship: She forms one with Pearl at the end of the episode she debuted in, though their friendship (and rivalry) is less about popularity and more to do with being an uncool nerd/Geek versus Pearl's cool cheerleader status.
• Dub Name Change:
  • "Thaddina" in the German dub.
  • In the Brazilian Portuguese dub, she was known as "Lulina" and later "Molusquina" (both taken from Squidward's translated name, Lula Molusco).
• Early-Installment Weirdness: In "The Goofy Newbie", their one interaction so far in the main series, she and Patrick act like complete strangers to each other. This could likely be because this episode aired in 2019 and the Patrick Star Show wouldn't debut until two years later.
• Establishing Character Moment: When she first speaks, she complains about Pearl rubbing her cheerleader status in her face, introducing the audience to the small rivalry she has with Pearl.
  Squidina: Do you always have to rub it in my face that you're a cheerleader?
  Pearl: (rubbing pom poms in her face) Yes. I. Do!
• Expy: She's one for the squid girl incidental, who was often seen as one of Pearl's classmates or at Mrs. Puff's Driving School. She was even called Squidina in her original model sheet. Crew member Vincent Waller stated pre-The Patrick Star Show that the squid incidental could be Squidina's mother.
• Genki Girl: A chipper, enthusiastic squid girl.
• Girly Girl with a Tomboy Streak: She's an adorable, girly squid who likes comics and action figures.
• Happily Adopted: She is a squid who loves her adoptive sea star family.
• Nerdy Nasalness: She talks with a bit of a nasal-sounding voice to accentuate her geeky and nerdy personality.
• Non-Indicative Name: Interestingly subverted: unlike Squidward, Squilliam and other octopi characters with squid-themed names, Squidina actually is a squid, not an octopus. Played straight by her surname of "Star", but this is justified due to being adopted by a family of starfish.
• Proud to Be a Geek: She has an undying passion for science and comic books and isn't afraid to let people know it. However, she's so proud that she views cheerleaders like Pearl as "airheads". Of course, she gets some Character Development by the end of the episode and changes her tune enough to form a Cool Kid-and-Loser Friendship with Pearl.
  Pearl: (cheering) I'm number one! You're number two! I'm gonna beat the nerd out of you!
  Squidina: No one can beat the nerd out of Squidina!
• Retcon: Her appearance as Patrick's adopted sister in The Patrick Star Show contradicts the events of "The Goofy Newbie", where the two's interactions gave no indication they had anything more than a customer-employee relationship.
• Sibling Yin-Yang: An adopted case with Patrick. Squidina is a smart science nerd with energy to spare, while Patrick is a mellow idiot.
• You Don't Look Like You: In The Patrick Star Show, she wears glasses and has a snout with an overbite. In the main series, however, she lacks glasses and has a flat face with one tooth similar to Patrick, but these may simply be a result of her body changing with age.

Squidward's family and pets

Mrs. Tentacles

Mrs. Tentacles

"Don't wanna hear it."

Voiced by: Dee Bradley Baker ("Fools in April"), Rodger Bumpass
Debut: "Fools in April"

Squidward's mother.

---

• Abusive Parents: To a degree, she is verbally abusive to her son. In "Fools in April", she screamed at her own son "YOU STINK!". She also famously insulted him in "Sportz?", by giving him somewhat of an inverted your mom insult. In "Scavenger Pants", she joked that she only had one child because "One of him [Squidward] was enough." In one issue of SpongeBob Comics reveals that the weakness of Squidward’s superhero persona is his mother calling him a disappointment.
• Early Installment Character-Design Difference: Her appearance in her debut episode, "Fools in April", depicted her with white puffy hair, lipstick, and eyelashes without any visible wrinkles◊, whereas her later design makes her look visibly older while giving her lavender hair, glasses, and gold earrings. She would be redesigned yet again in "Momageddon", having darker hair and a slightly younger appearance.
• Strong Family Resemblance: She looks like an old lady version of her son. Even her house looks like a clone of Squidward's house, just with curly hair.
• Vocal Dissonance: The deep, gruff, manly voice she was given in "Fools in April".
  Mrs. Tentacles: YOU STINK!!!

Granny Tentacles

Granny Tentacles

"Squidward, you're my favorite grandson... because you're my only grandson."

Voiced by: Mary Jo Catlett ("Chum Fricassee"), Cree Summer (The Patrick Star Show)
Debut: "Chum Fricassee"

Squidward's grandmother, who lives in a teapot house and is capable of making chum edible by making fricassee from it.

Several years before Squidward attempted to sell her recipe at the Chum Bucket, Granny Tentacles lived across the street from the Stars. She would regularly butt heads with Patrick and his family since The Patrick Show would often interrupt her sleep. Granny Tentacles was also in a relationship with GrandPat Star, Patrick's grandfather, having known him since childhood when she was a member of GrandPat's gang, the Kelp Bed Kids.

---

• Ascended Extra: Before The Patrick Star Show came along, Granny Tentacles only made one physical appearance in SpongeBob SquarePants. The Patrick Show, on the other hand, promotes her to a supporting character.
• Gruesome Grandparent: After finding out her grandson had been selling her chum fricassee recipe at the Chum Bucket, Granny Tentacles repeatedly crushes Squidward's foot with her walker and encourages the customers to burn down the restaurant in retaliation, all while scolding him for undercooking her recipe and giving people stomach aches as a result.
• Interspecies Romance: Granny Tentacles and GrandPat, an octopus and a starfish respectively, are both shown dating in The Patrick Star Show.
• Strong Family Resemblance: Both of Granny Tentacles' designs have her wear an outfit similar to Mrs. Tentacles. While her first design gives her attire and hair a different color palette to set her apart from the younger elder Tentacles, The Patrick Star Show changes her color scheme so that she looks nearly identical to Mrs. Tentacles design-wise (though unlike Mrs. Tentacles, Granny Tentacles still doesn't wear glasses).
• Suspiciously Similar Substitute: Since Squidward is Demoted to Extra in The Patrick Star Show, most of his traits (grouchy neighbor who can't stand their neighbors' antics and is constantly treated like a Cosmic Plaything) are given to his grandmother.

Mr. Krabs' family and pets

Betsy Krabs

Betsy Krabs

Voiced by: Paul Tibbitt (first 2 appearances) and Sirena Irwin (later 3 appearances)
Debut: "Sailor Mouth"

Mr. Krabs' mother, who makes five appearances.

---

• Beware the Nice Ones: She was furious when she thought Plankton was just using her to get the Krabby Patty secret recipe.
• Brave Scot: She speaks with slight hints of a Scottish accent in later appearances, and has enough Beware the Nice Ones moments to make one wary of her.
• Good Parents: She seems to be a loving, fair, but firm mother to Mr. Krabs and also is willing to discipline SpongeBob and Patrick on occasion.
• Larynx Dissonance: In her first two appearances, she sounds like a man due to being voiced by Paul Tibbit.
• Nightmare Fetishist: Much to Mr. Krabs' embarrassment, Betsy was really looking forward to watching Patrick get mauled by a lionfish.
• Older Than They Look: Looks about 20 years younger than she is.

Captain Redbeard

Captain Redbeard

Voiced by: Dennis Quaid ("Grandpappy the Pirate"), Clancy Brown ("Senior Discount")
Debut: "Grandpappy the Pirate"

Mr. Krabs' paternal grandfather, who works as a pirate.

---

• Arc Words: Captain Redbeard lives by the pirate's code of honor: "Never tell a lie."
• Captain Colorbeard: His name is a typical pirate captain's name, but a rather misleading one, since while he himself is red, his beard is gray (though it may have been red when he was younger.)
• Disappointed in You: Captain Redbeard was disappointed to hear that Mr. Krabs wasn't actually a real pirate. Not because he went against the family business but because he lied.
• Dressed to Plunder: Captain Redbeard is always in his pirate uniform.
• Eyepatch of Power: Captain Redbeard wears an eyepatch that he doesn't even need because both of his eyes work just fine. He just wears it because it makes him look cool.
• Family Business: Captain Redbeard considers pirating to be the Krabs family business. While Mr. Krabs obviously hasn't followed the trend exactly, his ridiculously high prices and unethical business practices are still more than enough to qualify as piracy in Redbeard's eyes.
• Father Neptune: Captain Redbeard is a 100-year-old salty seadog and a dedicated swashbuckling pirate, who sails the seven seas and looks for buried treasure.
• Honesty Is the Best Policy: Captain Redbeard's #1 rule is that you should never tell a lie, even if the truth is something that someone else doesn't want to hear.
• Like Father, Like Son: Or in this case, like grandfather, like grandson. Captain Redbeard is a greedy, penny-pinching, cheapskate, who shamelessly steals money from his own family.
  Mr. Krabs: I knew I got me talent from someone.
• Non-Indicative Name: Due to his old age, his red beard has now turned gray.
• Red Right Hand: His left claw is noticeably smaller than his right, especially when compared to his grandson, Eugene.
• Seadog Beard: He has a beard that's so important, that he's named after it.
• Semiaquatic Species Sailor: He is a crab and a pirate. Crabs can go both on land and underwater.
• You Don't Look Like You: In "Senior Discount", his skin became more faded and pinkish.

Mr. Doodles

Mr. Doodles

Voiced by: Dee Bradley Baker
Debut: "Sandy's Rocket"

The pet worm of Mr. Krabs, who has made three small, blink-and-you'll-miss-him appearances.

---

• All Animals Are Dogs: Like all worms in the SpongeBob universe, Mr. Doodles is the undersea equivalent of a dog. Mr. Doodles barks, pants, sniffs things, and likes going for walks.
• Animal Jingoism: Averted. In "Gary & Spot", Mr. Doodles was shown partying with Gary.
• Cat/Dog Dichotomy: Or in this case, Snail/Worm Dichotomy, and it's averted. Mr. Doodles is actually good friends with Gary and they never argue or fuss because of their species.
• Chuck Cunningham Syndrome: Mr. Doodles quietly stopped appearing in the show after the Season 3 episode, "As Seen on TV". Even episodes that took place mainly in Mr. Krab's home didn't show even a trace of his existence. However, he finally returned to the series in the Season 12 episode, "Gary & Spot".
• Given Name Reveal: His name wasn't mentioned until his second appearance.

Plankton's family and pets

Lily Plankton

Lily Plankton

"Oh, Plankton, you always were my favorite granddaughter."

Voiced by: Laraine Newman
Debut: "Gramma's Secret Recipe"

Plankton's grandmother.

---

• Dirty Old Woman: In "Grandmum's the Word," Lily falls in love with Squidward, a man who is much younger than her, and at one point imagines having him as a slave.
• Early Installment Character-Design Difference: Lily seemingly had two eyes (as evidenced by her glasses having two lenses) instead of one like the rest of her family in her debut appearance, but subsequent appearances depict her with one eye instead.
• Given Name Reveal: Lily's first name wasn't revealed until "Grandmum's the Word."
• Handbag of Hurt: "Grandmum's the Word" has Lily hit SpongeBob, Mr. Krabs, and even her own grandson with her purse as a Running Gag.
• Villainous Lineage: "Grandmum's the Word" reveals that Lily shares her grandson's desire to take over the world by stealing the Krabby Patty Formula.

Spot

Spot

Voiced by: Dee Bradley Baker
Debut: "Plankton's Pet"

An amoeba who Plankton adopts from the animal shelter. He becomes a sidekick to Plankton and Karen, as well as the third resident of the Chum Bucket.

---

• All Animals Are Dogs: Spot barks, goes for walks, and is capable of protecting his owner from danger, just like a dog.
• The Bus Came Back: Spot returns in the aptly named Season 11 episode "Spot Returns" and has made sporadic appearances since.
• Collection Sidequest: He's a collectible bonus character in every level of The Cosmic Shake.
• Morality Pet: To Plankton. Caring for the amoeba really brings out Plankton's nicer side.
• Ridiculously Cute Critter: So adorable that even Plankton falls for him.
• Your Tomcat Is Pregnant: In "Spot Returns," it is revealed Spot can reproduce asexually when Plankton and Karen find out through an X-Ray that Spot is pregnant and not fat, and the entire plot is about putting Spot's amoebas under control.

Other recurring characters

Captain / Painty the Pirate

Painty the Pirate

Voiced by: Patrick Pinney
Debut: "Help Wanted"

The painting of a pirate captain who appears in the show's opening.

---

• Ambiguous Situation: Whether or not he actually is Burger Beard from the Big Damn Movie is left vague.
• Insert Cameo: In an unusual example, his lips belong to the show's creator, Stephen Hillenburg.
• Synchro-Vox: He's a still painting with live-action lips, though it's not as offputting as most instances of this since the painting is of a realistic human being.
• Title Theme Tune: He leads the singing of this in nearly every episode.

Hans

Hans

Need a hand?

Voiced by: Tom Kenny
Debut: "Suds"

A giant live-action hand.

---

• A Day in the Limelight: Hans is given a major role in "SpongeBob's Bad Habit", where SpongeBob has a nail-biting habit and goes to see a hypno-therapist to help him. Appropriately, this man in Hans and his hypnotism works like a charm. He also plays a big part in the episode "Handemonium", where he gets into a fight with the automated giant metal hand on top of the Chum Bucket.
• Depending on the Writer: Hans repeatedly switches from a right hand to a left hand throughout the series. This is most noticeable in "Handemonium", where he changes from a right to a left throughout the episode depending on what side of the screen he's coming from.
• Insert Cameo: The guy who's hand they took a picture of to play Hans is showrunner, Peter Bennett.
• Medium Blending: Hans is a live-action hand in an animated cartoon.
• Ooh, Me Accent's Slipping: In "Model Sponge", he has an Austrian accent like Arnold Schwarzenegger, rather than his traditional German accent.
• Punny Name: His name is a play on "Hands".
• The Quiet One: Early in the series, he was virtually silent, his only lines in "Imitation Krabs" and "Suds" being "Ooh, yum-yum!" and "Here's your lollypop". He has a longer line in "Model Sponge" ("Would you keep it down? I'm trying to concentrate!"), and in "SpongeBob's Bad Habit" and "Handemonium" he finally speaks in full sentences and holds conversations with the characters.

Bubble Buddy

Bubble Buddy

Voiced by: Brad Arbell
Debut: "Bubble Buddy"

A bubble-guy created by SpongeBob to be his buddy.

---

• Alliterative Name: Bubble Buddy
• Ambiguous Situation: While there's no doubt he's alive at the end of his eponymous episode, it's not clear if he always was or if he came to life at some point.
• Animate Inanimate Object: At the end of his debut episode, it's revealed that he really is alive and presumably has been the whole time.
• Ascended Extra: He appears as one of the recurring companions in Battle for Bikini Bottom, often giving SpongeBob valuable information on how to use abilities or defeat enemies, or just crack jokes with him.
• The Bus Came Back: He reappears in "Bubble Buddy Returns", and then again in "Bubbletown".
• The Cameo: Makes a couple of background cameos in "Mall Girl Pearl".
• Companion Cube: He was created when SpongeBob needed a new friend. Turns out, he's sapient.
• Elemental Embodiment: Bubble Buddy is a bubble elemental.
• Exactly What It Says on the Tin: He is a bubble, who serves as SpongeBob's buddy.
• Late-Arrival Spoiler: His appearance in Bubble Buddy Returns would already spoil for new viewers that he is a living, talking bubble.
• Plot Allergy: As revealed in "Bubble Buddy", Bubble Buddy is lactose intolerant.
• Real After All: Revealed to actually be alive and not a figment of SpongeBob's imagination at the very end of his debut episode.
• Signature Headgear: In "Bubble Buddy Returns" and "Bubbletown", he is seen wearing a fedora. In the latter, it makes him more easily distinguishable from the other citizens of Bubbletown.
• The Voiceless: He is silent in his debut episode, until the very end.

Man Ray

Man Ray

Voiced by: John Rhys-Davies (first two appearances), Bob Joles
Debut: "Mermaid Man and Barnacle Boy III"

"I, the supreme authority of wickedness, I, the evil Man Ray, command you to release me from this frozen prison... at once!"

---

• Ambiguously Human: He superficially resembles a man in some kind of costume, but when he takes his "mask" off, he appears to be headless. If "Man Ray Returns" and The Patrick Star Show episode "X Marks the Pot" are any indication, his body is fully human◊, but the question of what, if anything, is underneath his mask remains unresolved.
• Arch-Enemy: He's the main foe of Mermaid Man and Barnacle Boy.
• Bad "Bad Acting": He literally says out loud "Oh sob! Oh cry!" when trying to act sad.
• Cool Mask: Subverted. What appears to be a helmet is actually his head, though he can detach it and still is able to talk without it somehow.
• Create Your Own Villain: The Patrick Star Show episode Super Sitters revealed that Man Ray was raised at the Super Child Daycare along with Mermaid Man, Barnacle Boy, Dirty Bubble and many others. When Patrick and SpongeBob traveled back at this time, they showed him what he will destined to be as an adult along with Dirty Bubble, The Coral Creep and Exo-Woman.
• Expy: Just as Mermaid Man and Barnacle Boy are ones for Aquaman and Aqualad, Man Ray is one for the Aquafamily's Arch-Enemy, Black Manta... though obviously, being from a goofy, lighthearted kid's cartoon, he's nowhere near the psychopathic monster Black Manta is.
• Evil Brit: Courtesy of his first voice actor John Rhys-Davies, who is British. However, it was dropped in later appearances.
• Evil Is Hammy: Much like the classic supervillains he is based on, Man Ray is prone to delivering long, dramatic speeches.
  Man Ray: By the supreme authority of wickedness, I, the evil Man Ray, command you to release me from this frozen prison at once!
• Heel–Face Revolving Door: Seemed to pull a Heel–Face Turn in his first appearance, but afterwards reverts to his evil status by the next time we see him. In his third appearance though, he preferred living a normal life, but SpongeBob got on his nerves when he didn't do anything wrong at all. Any evil he's done outside of the Bad Future amounts to Poke the Poodle in "Mermaidman and Barnacleboy V" or just being a villain for hire when he teamed up with Plankton.
• Human Popsicle: He was frozen in tartar sauce since Mermaid Man's prime, until SpongeBob and Patrick freed him.
• Laughably Evil: Despite his status as Mermaidman and Barnacleboy's nemesis, Man Ray is just as goofy as any other character on the show. His actions, no matter how villainous, always result in Amusing Injuries.
  Man Ray: I'll fake my way through this just like I did in high school! [Evil Laugh]
• Metronomic Man Mashing: He grabs Patrick by the head and repeatedly slams him against the ground after the latter claims that the box he keeps dropping on Man Ray's foot contains Patrick's wallets.
• Named After Somebody Famous: After the surrealist artist, Man Ray. And of course, it's a pun on a manta ray.
• No Face Under the Mask: His "mask" is actually a removable head.
• Not-So-Harmless Villain: A minor villain in the normal series, but a Bad Future where he won proved he was actually able to take over the world and turn it into a dictatorship where everyone was enslaved to his will.
• Red Eyes, Take Warning: He has red eyes, and he's evil.
• Restraining Bolt: SpongeBob and Patrick take advantage of Man Ray's Tickle Belt when they teach him to become good, activating it whenever he does something bad.
• Sealed Evil in a Can: In his debut episode, he was frozen in tartar sauce until SpongeBob and Patrick accidentally thawed him out.
• Tickle Torture: His weakness in his introductory episode is a belt that tickles him whenever a button is pressed ("As seen in Episode #17!") He tricks SpongeBob into unlocking the belt for him, but still feels the tickling sensation when he attempts to rob a bank.
• Villains Out Shopping:
  • For most of "Man Ray Returns", he tries to have some time off from villainy by renting Squidward's house. He gets back to being evil because SpongeBob and Patrick wouldn't leave him alone.
  • In a more literal version of this Trope, we frequently see him out doing completely ordinary errands, like buying groceries or going to the laundromat.

Dirty Bubble

Voiced by: Charles Nelson Reilly (First appearance, Lights, Camera, Pants!), Tom Kenny (All other appearances)
Debut: "Mermaid Man and Barnacle Boy II"

---

• Chuck Cunningham Syndrome: Hadn't made a prominent appearance after "The Bad Guy Club for Villains" until the season 12 episode "Dirty Bubble Returns."
• Create Your Own Villain: The Patrick Star Show episode Super Sitters revealed that Dirty Bubble was raised at the Super Child Daycare along with Mermaid Man, Barnacle Boy, Man Ray and many others. When Patrick and SpongeBob traveled back at this time, they showed him what he will destined to be as an adult along with Man Ray, The Coral Creep and Exo-Woman.
• Hidden Depths: Apparently, he's a Paddle-ball champion with a consecutive hit score of over 5 million.
• Jagged Mouth: An asymmetrically jagged, crooked-looking mouth, with small "smile lines" on each end. Doesn't affect his "awesome surface tension" at all, though.
• Laughably Evil: Could rival Man Ray in his hilarity, especially in the earlier seasons, where all it takes to defeat him is to pop him with any sharp object.
• Rhymes on a Dime: In "Dirty Bubble Returns" and "SpongeBob Patty Pursuit", he began rhyming every sentence he made.
• They Killed Kenny Again:
  • He gets killed in "Mermaidman and Barnacleboy II" and "Patrick-Man!", but reappears alive and well in later episodes. This might be because he's a bubble and presumably can reform as long as there's enough of him left to make up a new body.
  • He's also formed by Barnacle Boy in "Back to the Past" before getting popped almost immediately afterwards.
• Weaksauce Weakness: Being a bubble, he can be easily put out of commission if he's popped.
• We Hardly Knew Ye: Subverted. In his debut, he is quickly popped by SpongeBob less than a minute after he shows up, but is seen alive and well in his second appearance.

Atomic Flounder

Atomic Flounder

Voiced by: Carlos Alazraqui ("Mermaid Man and Barnacle Boy II"), Dee Bradley Baker ("The Bad Guy Club for Villains")
Debut: "Mermaid Man and Barnacle Boy II"

A flounder with radioactive powers, who is now retired.

---

• Grumpy Old Man: Atomic Flounder can be rather fussy, especially when annoyed by SpongeBob and Patrick.
• I Was Quite a Looker: Despite being an old bag now, Atomic Flounder used to be a buff, muscular bodybuilder back when he was young and active. On the other hand, he had a single eye on his face, an arm growing from his right shoulder, and an eye growing from the right side of his head.
• Mutants: Atomic Flounder is the product of a radioactive disaster.
• Rage Breaking Point: Although Atomic Flounder is now retired and wishes no ill will on Mermaid Man and Barnacle Boy, in "Mermaid Man and Barnacle Boy II", Atomic Flounder got really mad, when he was ambushed by SpongeBob, leading to him freaking out and barfing a toxic laser blast into Barnacle Boy's face.
  Atomic Flounder: Why, if I weren't retired, I'd...I'd-RRRRAAAAAAAAAUUUUUGGGGHHHHH!!!
  [Fires his atomic breath straight into Barnacle Boy's face.]
  Atomic Flounder: -do that! [pushes past the trio] Out of my way, punk!
• Progressively Prettier: Zig-Zagged. His younger self was redesigned with a more muscular bodybuilder physique, unlike the standard flounder look the show uses. However, the redesign also made him more obviously mutated.
• Retired Monster: Back in his day, Atomic Flounder was an evil supervillain, who fought with Mermaid Man and Barnacle Boy. Now, he's just a kindly old man, who is on good terms with his former rivals.
• You Don't Look Like You: Aside from the fact that he pretty much aged into another person, in "Mermaid Man and Barnacle Boy II", a cardboard cutout of him depicts him as green and wearing a hazmat suit.

Narlene and Nobby

Voiced by: Kate Higgins (Narlene), Carlos Alazraqui (Nobby)
Debut: Kamp Koral

Narlene and Nobby are a pair of narwhal siblings who first appeared in the Kamp Koral spinoff series and were later added into the original series, with aged up designs.

---

• Amazing Technicolor Wildlife: Narlene is pink and Nobby is yellow, neither of which is the color of actual narwhals.
• Animals Not to Scale: Like Pearl, they are whales the size of fish.
• Barefoot Loon: Both Narlene and Nobby never wear any shoes. Not to mention they have more visible toes than the rest of the Bikini Bottomites.
• Big Little Brother: In Kamp Koral, Nobby is shorter than his older sister. In the main show, however, he is huge and muscular.
• Canon Immigrant: They first appeared in Kamp Koral before showing up in the main series.
• Half-Witted Hillbilly: In "Upturn Girls", Narlene and her lack of wisdom about sophisticated urban life proves a detriment when Pearl takes her on a city tour.
• Handy Feet: Narlene often likes to grab things and interact with others using her feet, usually to the disgust of others with the exception of SpongeBob.
• Misplaced Wildlife: Narwhals are native to northern Arctic waters, yet the series takes place in the tropics.
• Nonstandard Character Design: They are among the few characters besides SpongeBob himself that have humanoid hands and feet instead of fins.
• Plant Hair: Narlene has a wig made up of seaweed on her head.
• Punny Name: Narlene's name is a portmanteau of "Narwhal" and "Arlene".
