Supporting cast


    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!"

    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! We kid you not!
  • 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: He gets a lot of misfortunes in the segments featuring him.
  • The Chew Toy: If something bad happens during his segments, it's usually him it'll happen to.
  • Dressed to Plunder: Wears the typical parts of a pirate costume, though he doesn't really do any actual plundering.
  • Excited Kids' Show Host: Especially since he's played by Tom Kenny.
  • Fanboy: He's the president of the SpongeBob fan club.
  • Iron Butt-Monkey: Has been blasted through multiple house, 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 SpoongeBob betrayed us, 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).
  • 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.
  • 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: The accent and outfit go along well with it.
  • 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), Doug 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.
  • Deadpan Snarker: Often snarks at Patchy's mishaps.
  • Hypercompetent Sidekick: Although everyone's hypercompetent compared to Patchy.
  • Polly Wants a Microphone: Like most parrots in fiction, Potty is able to speak instead of just mimicking what other people say.
  • Small, Annoying Creature: 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.
  • 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

Click here to see his younger self. 
Voiced by: 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)
Debut: "Mermaidman and Barnacleboy"

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

  • Ambiguously Human: He certainly looks like a (cartoon) human, but he can breathe underwater, is the same size as a crab, and has superpowers. Also, despite his name, he doesn't seem to be one of the merfolk, given he looks nothing like the ones we see in the series.
  • Cloud Cuckoolander: He has eccentric beliefs and habits. May be semi-justified as onset Alzheimer's/Dementia.
  • The Cloud 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: Of Aquaman. His younger self also looks like Aquaman, and both have the ability to summon the creatures of the sea via telepathy. Storywise he's modeled after Batman - particularly, the television version.
  • 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.
  • Ink-Suit Actor: Looks exactly like Ernest Borgnine.
  • I Was Quite a Looker: His younger self is more muscular and handsome.
  • Large Ham: EVIL! EVIL!
  • Leitmotif: The Lineman is his associated theme.
  • 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: Was retired, but became "semi-retired" thanks to SpongeBob.
  • Put on a Bus: The character 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 the Ernest Borgnine and Stephen Hillenburg's wishes that Ernest would never be replaced with a soundalike.
  • Retired Badass: He used to be a superhero, with Barnacle Boy as his sidekick, when he was younger.
  • Scatterbrained Senior: Hoo boy. If you think Patrick has a bad memory, you ain't seen nothing yet.
  • Seashell Bra: Wears one over his clothes for some strange reason.
  • Senior Sleep Cycle: He can even sleep with his eyes open.
  • Token Human: And yet he is able to survive underwater. Apparently, some mermaids gave him a special starfish that allowed him to breathe.
  • 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 
Voiced by: Tim Conway (1999-2012), Burt Ward (young)
Debut: "Mermaidman and Barnacleboy"

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

  • Ambiguously Human: For the same reasons as Mermaid Man, it's hard to tell whether he's human or not.
  • Butt-Monkey: He suffers the most out of the two.
  • Deadpan Snarker: Can be sarcastic and snide, especially when it comes to SpongeBob's antics.
  • Expy: His suit is modeled after the Silver Age Aqualad. Oddly, his character is more of an Expy of Robin than of Aqualad.
  • 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 he 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.
  • Jerkass: He's noticeably more of a jerk than Mermaid Man.
  • Jerk with a Heart of Gold: He may seem harsh, but he cares about Mermaid Man.
  • 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.
  • Old Superhero: He lives in a retirement home. It doesn't get older than that.
  • Put on a Bus: With Ernest Borgnine's death, it seems Barnacle Boy was retired along with him, barring the occasional cameo via photograph or toy. In fact it's become more common to see characters cosplay the characters than the characters actually appearing. Not helping is that Tim Conway himself passed away in 2019 after being diagnosed with dementia the previous year. Like with Mermaid Man, 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
"Who dares disturb the Flyin' Dutchman?!"
Voiced by: Brian Doyle-Murray
Debut: "Scaredy Pants" note 

A old pirate who died a long time ago, but instead of burying him, they used him 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.
  • 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.

    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 nears. 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.
  • 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.
  • Prongs of Poseidon: King Neptune always wields with him a large trident.
  • Redhead In Green: King Neptune is a redheaded merman with green skin.
  • You Don't Look Like You: His appearance in the movie differs greatly from his appearance in the series.

    Larry the Lobster 

Larry the Lobster
"I have a date with the tanning booth."
Voiced by: Doug Lawrence (most speaking appearances), Bill Fagerbakke (grunts in "MuscleBob BuffPants")
Debut: "Ripped Pants"

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

  • Amazing Technicolor Wildlife: Has the color of a boiled lobster. Justified by that he tans a lot.
  • Ambiguously Related: A line of dialogue in "Spongebob on Duty" implies he was raised by a (now elderly) fish couple, though it is never elaborated on in any other episode.
  • 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.
  • 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 and dismissive of obvious weaklings like SpongeBob and Patrick. Otherwise, see Characterization Marches On.
  • Lovable Jock: Easily the physically strongest character and one of the friendliest after SpongeBob himself.
  • Naked People Are Funny: Along with SpongeBob, Patrick, Mr. Krabs, Mrs. Puff, and Pearl, he ends up naked in public when the two hours of the cycle of Neptune's Moon are over and everyone returns to their normal selves. Unlike SpongeBob and Patrick (who are not bothered by their sudden nudity) and the others (who run away in embarrassment the instant they realize they're nude), Larry promptly covers himself using a flower.
  • 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 Licensed 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.
  • Walking Shirtless Scene: Always seen this way.

    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.
  • 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 is 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"

  • 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.
  • Out of Focus: Post-movie, borderlining on Chuck Cunningham Syndrome, as she didn't appear at all in seasons six or seven.
  • 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.

    Realistic Fish Head 

Realistic Fish Head
Voiced by: Doug 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
  • Casual Danger Dialog: 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 to] 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.
  • 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 now go love to news chopper 7.
  • 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!
  • Meaningful Name: Perch is a perch.
  • Mr. Exposition: Some episodes open with news reports by Perch Perkins, giving the audience an explanation on what the episode is gonna be about.
  • Palette Swap: 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 regained his purple scheme.
  • 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?
  • This Just In!: Has said this a lot on the news.
  • 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 and even now, we'll occasionally have episodes, where he appears as orange.

    The Bikini Bottom Fish 


Voiced by: Tom Kenny
Debut: Tea at the Treedome

  • Animal Motifs: Jellyfish are treated like butterflies in the SpongeBob universe. Much like how snails are cats, worms are dogs, scallops are birds, etc.
    • However, the jellyfish play the roles of other animals too such as bees (with them often swarming, buzzing, and stinging characters) and cows (with characters being able to milk their stingers for jelly).
  • 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").
  • Big Bad: The giant jellyfish at the end of "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.
  • Furry Confusion: Fish, sponges, starfish, octopuses, etc. are "human animals", while jellyfish, snails, amoebas, and worms are the "animal animals" in the SpongeBob universe.
  • 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.

Bikini Bottomites

    Bubble Bass 

Bubble Bass
"You forgot the PICKLES!!!"

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 a recurring regular since Season 9, after falling from the face of the Earth for several years, 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 Eater: A fan translated his order to be a Krabby Patty with over twenty patties. Plus, he took off running when Spongebob threw a single piece of popcorn.
  • The Bus Came Back: Bubble Bass first made a few appearances in Season 1, before having an 11 year absence. Since his return in Season 8, he's had numerous small roles, and even a few big ones.
  • 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.
  • Demoted to Extra: 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.
  • 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.
  • 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."?
  • 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.
  • 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.
  • Hate Sink: Exists to be a cruel, unlikable bully, though from Season 8 onward he occasionally teams up with Spongebob against a common foe.
  • 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 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.
  • 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.
  • Meaningful Name: Say his name repeatedly and quickly and you'll discover why the name is perfect for him.
  • Pet the Dog: In "Plankton's Good Eye", he came to thank Plankton for rescuing him.
  • Remember the New Guy?: Kind of; in his first appearance it's made clear he and SpongeBob know each other.
  • 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.
  • Stout Strength: He's strong enough to effortlessly push away an entire crowd of people.
  • 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.


"Surfs up, dude!"
Voiced by: Carlos Alazraqui
Debut: "Ripped Pants"

A surfer dude who loves to go surfing at Goo Lagoon. He is good friends with SpongeBob and Larry.

  • Catchphrase: "Dude!"
  • Death Is Cheap: Scooter flat out dies in "Bubble Buddy", when he drowns. But of course, he's inexplicably back to life in later episodes.
  • Dropped a Bridge on Him: Subverted. He appears to be killed off in a contrived manner when he drowns in "Bubble Buddy", but he comes back in later episodes alive and well. Unless he's a ghost and Nickelodeon's Bikini Bottom Mysteries episode on him can be taken with some degree of canon.
  • The Ditz: In "My Pretty Seahorse", he mistakes a live seahorse for a toy seahorse and sticks a quarter up it's anus, getting him kicked in the stomach so hard he flies across Bikini Bottom.
  • Dude, Not Funny!: In "Ripped Pants", even Scooter is unhappy with SpongeBob pretending to drown.
    Scooter: [disappointed] Dude.
  • Irony: In "Bubble Buddy", Scooter drowns ... a fish drowns.
  • Mellow Fellow: Scooter never seems to be unhappy about anything. In fact, he didn't even get mad in "Bubble Buddy", when the episode's titular character downright kills him, by refusing to dig him up, when the tide was coming in. In fact, he was overjoyed, when he came back as an angel to tell people about what happened to him.
    Scooter: Dudes! He made me experience high tide!
  • Recurring Extra: Whenever there's an episode set at Goo Lagoon, he's usually there.
  • Surfer Dude: Scooter is the very embodiment of this trope and he spends most of his time surfing at Goo Lagoon.
  • They Killed Kenny: He died several times but came back in later episodes thanks to Negative Continuity.
    • In "Bubble Buddy", he apparently drowned when SpongeBob left him buried up to his neck on the beach. He appeared later in that episode as a angel.
    • In "Something Smells", he gets killed by SpongeBob's bad breath.
    • In "My Pretty Seahorse", after he thinks Mystery the seahorse is a ride and inserts a coin into her, she kicks him and he explodes where he lands.


"My leg!"
Voiced by: Various (primarily Doug Lawrence)
Debut: "Reef Blower"

The guy 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.

  • A Day In The Lime Light: He is focused on in the episode appropriately titled "My Leg!".
  • 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.
  • Blowing a Raspberry: Fred had an addiction to this in "Face Freeze", doing it to everyone he saw go by.
  • 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!".
  • Butt-Monkey: There's a reason he says "My Leg!"
  • Catchphrase: MY LEG!!!
  • Chained to a Railway: Fred purposefully tied his leg to a railroad track in "My Leg!", in hopes that it would injure him once again, sending him to the hospital to see Nurse Bazooka.
  • Chuck Cunningham Syndrome: Ever since Fred was officially turned into a consistent supporting character, his blue and brown palette swaps completely stopped appearing.
  • 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 amBritish 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.
  • Jerkass Ball: In "Face Freeze", Fred walked around Bikini Bottom, sticking his tongue out at everyone he saw.
  • 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.
  • Marilyn Maneuver: Did this in "My Leg!", where he stood over a subway vent, which blew up his skirt, revealing to the world his live-action legs.
    Fred: [seductively] My Legs.
  • Nice Hat: Sometimes Fred is shown wearing a brown fedora.
  • Ow, My Body Part!: He's constantly heard yelling "MY LEG!!!", even when it is not even his leg being put through harm.
  • Palette Swap: He is in both brown and blue versions.
    • There is a brown-green version used only once, in "Professor Squidward".
  • 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-Duplication: Episodes such as "The Chaperone" and "The Paper" have shown multiple Freds all together in crowd shots.
  • 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.
  • Your Cheating Heart: Fred is a real playa. As a background character, plenty of episodes showed Fred as a married man. He has been paired with a vast majority of the female background fish, and the pairings are almost never consistent.
    • When Fred became a more important recurring character, Fred mentioned that he was in love with Nurse Daisy Bazooka. Following the continuity here, this means that Fred was cheating on his wife/wives.
    • Also, in "King Plankton", Fred was seen on a date with yet another girl, proving that he can't even stay committed to the girls he was established to be in a relationship after he became a consistently-written character.
    • In the episode "Stormy Weather", Fred was once again seen holding hands with and hugging another woman. Sadie, the yellow fish. Sheesh! Can't this guy just pick a chick?

    Old Man Jenkins 

Old Man Jenkins
"Respect your elders!"
Voiced by: Dee Bradley Baker (standard 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.
  • Badass Beard: His latest appearances depict him sporting a big long gray beard.
  • Bald of Awesome: Old Man Jenkins completely bald but he's still totally awesome.
  • 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 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 Jenkins sees SpongeBob and tells him "I saw you on TV last night.", only for a flashback to reveal that Old Man Jenkins 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.
    • And 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 this song!
  • 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 Jenkins 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!"
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.
  • Alpha Bastard: 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.
  • 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), but normally his appearances are a sign Squidward will win this one.
  • Big Ol' Unibrow: He has a noticeable unibrow.
  • Born Lucky: He turned out to be lucky and successful, compared to Squidward.
  • 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".
  • 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.
  • 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 "Squlliam Returns" has him treat his friends to dinner, though they can't really eat it's so expensive, and to 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 is how self-loving he is, and possibly with every member of his species.
  • 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.
  • 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.
  • Villainous Breakdown: At the end of "Band Geeks", he has one. 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.

Voiced by: Jill Taley
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.
  • Bare Your Midriff: 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.

Voiced by: Aubrey Plaza
Debut: "Mall Girl Pearl"
Pear's friend, who is your typical goth girl.
  • 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".

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

  • 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.
  • You Gotta Have Blue Hair: Nixie has hot pink hair.

"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.

  • Adorkable: A cute science nerd.
    Squidina: Science, yay!
  • 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.
  • 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.
  • 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.
  • 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!
  • 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.
  • 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.
  • 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!

Voiced by: Doug 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.
  • Catchphrase: "AMAZING!"
  • 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
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.

    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.
  • Cultural Stereotypes: Lady Upturn talks and behaves like a stereotypical British person, in that she acts very snobbish and condescending to others and expects to be treated like royalty just for existing. She even comes from an extensive royal family, as she has the honorific "Lady" in her name 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

    Mrs. Tentacles 

Mrs. Tentacles
"Don't wanna hear it."
Voiced by: 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 Squidward was more than enough".
  • Bait-and-Switch: In "Krusty Towers", SpongeBob and Mr. Krabs go to her house as per Squidward's request for them to make him cookies the same way his mother did. At first, we see the duo throwing a body bag into the trunk of a car and slamming it with a shovel, implying that they kidnapped her. However, Mrs. Tentacles then enters and offers to help Mr. Krabs fit his bag of laundry in the back of the car.
  • 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!!!
  • You Don't Look Like You: Her appearance in her debut episode, "Fools in April", varied greatly from her official appearance now.
  • Your Mom: In "Sportz?", Sandy used one of these insults against Squidward, and his own mother came in to support the joke.
    Sandy: Tell it to your mother, Squidward?
    Squidward: Mother?
    Mrs. Tentacles: Don't wanna hear it.

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: See Mama Bear. Also, she was furious when she thought Plankton was just using her to get the Krabby Patty secret recipe.
  • 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, due to being voiced by Paul Tibbit.
  • Mama Bear: Do not mess with her son.
  • 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' paretnal grandfather, who works as a pirate.

  • Arc Words: Captain Redbeard lives by the pirate's code of honor: "Never tell a lie."
  • 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.
  • 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.
  • Seadog Beard: He has one that's so important, that he's named after it.
  • Strong Family Resemblance: Captain Redbeard looks like Mr. Krabs dressed as an old pirate dude.
  • You Don't Look Like You: In "Senior Discount", his skin became more faded and pinkish.



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.


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.

    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 the undersea equivalent of a dog. Mr. Doodles barks, pants, sniffs things, and likes going for walks.
  • Amplified Animal Aptitude: Pretty smart for a worm.
  • 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 three 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.

Other recurring characters

    Captain / Painty the Pirate 

Painty the Pirate

Voiced by: Patrick Pinney

  • Title Theme Tune: He leads the singing of this in nearly every episode.


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.
  • 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.
  • Punny Name: His name is a play on "Hands".

    Bubble Buddy 

Bubble Buddy

Voiced by: Brad Arbell
Debut: "Bubble Buddy"
A bubble-guy created by SpongeBob to be his buddy.

    Man Ray 

Man Ray
Voiced by: John Rhys-Davies (first two appearances), Bob Joles
Debut: "Mermaidman and Barnacleboy III"

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

  • Metronomic Man Mashing: Does this to Patrick 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 basically his 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.
  • 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.
  • Worth It: "Aaaaah, it tickles, but it's WORTH IT!"

    Dirty Bubble
Voiced by: Charles Nelson Reilly (first appearance), Tom Kenny
Debut: "Mermaidman and Barnacleboy 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."
  • 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.
  • 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 killed by SpongeBob (by complete accident) 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 Alazquari
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.
  • Mutants: Atomic Flounder is the product of a radioactive disaster.
  • Old Soldier: If you consider him a soldier in the war against good.
  • 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 and Patrick, leading to him freaking out and barfing a toxic laser blast into Barnacle Boy's face.
    Atomic Flounder: D'oh! Why, if I wasn't retired I'd ... I'd ... BWAAAAAAAAAAAAAAAAH!!! ... Do that!
  • Rapid Aging: Atomic Flounder seems to be the only villain who's actually changed in appearance with age, while lucky Manray got to be cryogenically frozen for a few years and Dirty Bubble doesn't look a day over ... er, ... whatever age he was back when Atomic Flounder was young.
  • 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 VI: The Motion Picture", a cardboard cutout of him depicts him as green and wearing a hazmat suit.

How well does it match the trope?
