Characters / Arthur

Because of the show's longevity, many characters have appeared throughout the show, each with a wide array of personalities and other character traits. The following describes characters from the picture books and animated television series by Marc Brown:


    open/close all folders 

    Common character tropes 
  • Book Dumb: Depending on the writer, any one of Arthur's immediate friends (except Brain), Arthur himself, or even the grown ups may be subject to this.
  • Bookworm: Every child character in the show has been seen in the library at least once.
  • But Not Too Foreign: Do any of the characters appear to be their ethnicities or nationalities? Then again, they are anthropomorphic animals...Or are they?
  • Cartoon Creature: One of the commonly asked questions about the show is the subject of which animal some of the characters are. Arthur and his family are the most confusing since they do not look like aardvarks at all. Prunella is another character that's debated upon; it is undecided on whether or not she is a poodle or a rat. PBS says she's a rat but Marc Brown says she's a poodle.
  • Close-Knit Community: Some episodes imply that the parents in Mr. Ratburn's class have all shared contact information with each other, while others make it clear that some of the parents are on a First-Name Basis.
  • Free-Range Children: Arthur and co. are about only eight years old and are in third grade, yet they run all about Elwood City much like teens several years older. None of their parents seem to be concerned, with the exception of what happens in S2's "Lost!" where Arthur accidentally rides the bus line to the city limits. Played With in an episode where for some reason, Brain and Binky think they're trapped at the soccer field and their moms forgot to pick them up. They go everywhere else in their neighborhood, but can't walk home?
  • Good Parents: All of the parents can count. What's interesting is that there are a rather startling number of examples of Arthur and D.W.'s parents not doing their job right (although when you consider the current length of the show, it's not entirely unexpected).
  • Idiot Ball: In later seasons especially, long-running characters are depicted doing dumb things, even though they know better, or in some cases, when they have been shown to learn better.
  • It's the Best Whatever, Ever!: Many of the show's characters have webpages detailing such experiences.
  • Limited Wardrobe The characters all have characteristic outfits by which they are identified. Depending on the episode or the setting, they may be changed.
  • Living Prop: There are a number of such characters in Arthur, mostly recurring townspeople and the students in D.W.'s class. Of important note are a pair of rabbit kids who've been in Arthur's class since the S1, but are not as developed as their classmates (in 15 seasons, the male one has only talked twice, and the female one never!). S13's "MacFrensky" had a class list with the names Alex & Maria on it, but some fans refuse to believe those are their names, since Arthur has had several other one-shot classmates over the years (never mind that the two rabbits were the only other two kids besides the already named regulars shown in class in that episode). It was confirmed at New York Comic Con 2013 that the two rabbit kids are indeed named Alex and Maria, and that the possibility of becoming Ascended Extras is open.
  • Not Allowed to Grow Up: Even though some characters have birthdays over the course of the show, the characters are shown to never physically age, outside of occasional flash-forward or fantasy. Lampshaded by D.W. in S1's "Arthur's New Year's Eve", suggesting that she's trapped in some kind of time warp that causes her to never get any older.
  • Punny Name: Most characters. The Crosswire family is probably the most obvious.
  • Renaissance Man: Most of the kids in Arthur's class play a sport and an instrument, and love to read. Even George, who struggles in these areas and starts off being shy and socially awkward, finds his stride as a carpenter and sports commentator.
  • Rounded Character: One of the top reasons for the show's success.
  • Rotating Protagonist: This is how things work, so different members of the cast get their own Episode Title Card.
  • Species Surname: Averted. See below.
  • Trademark Favorite Food:
    • Very subtle, but just about EVERYONE on this show likes snacking on popcorn.
    • There's a trademark favorite drink, at least in earlier seasons anyway, for the Read family. They are almost always seen drinking milk at meals.
  • Wise Beyond Their Years: A number of characters, from D.W.'s friend Emily to Arthur and his friends. They're not your average third-grade kids, after all. One of the best examples is D.W. and her zany Batman Gambit to trick Arthur and The Brain to take her to the science exhibit in S4's "Prove It!", and it worked.
  • Zany Scheme: Lampshaded by Arthur in "D.W. and Bud's Higher Purpose." During the intro, he explains D.W.'s propensity for this has gotten worse since she met Bud.

3rd/4th grade cast

     Arthur Timothy Read 
http://static.tvtropes.org/pmwiki/pub/images/arthur0_7125.png
Voiced by: Michael Yarmush (s1 – s5), Justin Bradley (s6), Mark Rendall (s6 re-dub; s7 - s8), Cameron Ansell (s9 - s11), Dallas Jokic (s12 - s15), Drew Adkins (s16 - s17), William Healy (s18 - s19), Jacob Ursomarzo (s20 - present)

The title character of the show. He and his family members are aardvarks, though it is not obvious due to the lack of elongated nostrils.
  • Adorkable: For a third grader, anyway.
  • Art Evolution: Applies to the book version, where he starts out as an actual aardvark (looking more like an anteater), and would slowly change in design until he came to his current look.
  • Adult Fear: Has a moment of this in-universe when he and his friends suspect they brought home a venomous snake. It's actually not.
  • Berserk Button:
  • Beware the Nice Ones: Normally a good-natured Nice Guy, but it's not a good idea to anger him. When D.W. destroyed his model plane and chose to blame him instead of apologising for her actions, he erupted.
  • Big Brother Bully: To D.W. and Kate at times. Of course, he won't admit that though.
  • Big "YES!": When he finds out that Buster is coming home from a Long Bus Trip with his father in S3's "Buster's Back".
    *Answering the phone* Hello? Yeah. Yeah? YEAH!
  • Bow Ties Are Cool: The Modus Operandi for his formal attire.
  • Butt Monkey: Would become one in later seasons.
  • Cats Are Mean: Was a firm believer of this, as exemplified in "Francine and the Feline (S3)"; as of "D.W.'s Furry Freak-Out (S12)" however, he seems to not mind them anymore.
  • Character Blog: The Arthur Facebook page.
  • Character Tics: Arthur fiddles with his glasses when he's lying.
  • Crazy Consumption: D.W., when imagining Arthur in a negative light, sometimes has him digesting cake either in one bite or in a mess. In "D.W. Gets Lost" this actually does happen.
  • Crowd Chant: Arthur gets one when he is cleared for embezzlement in "Arthur Accused!"
  • Deadpan Snarker:
    DW: Where were you between six months ago and yesterday?
    Arthur: Listening to you whine about the snowball 24 hours a day.
  • Eye Glasses: Has these. Was formerly self-conscious about them, too.
  • The Everyman: In sharp contrast to a group of widely varied friends with telling character traits. Lampshaded in S6's "Best of the Nest", when Arthur settles on "Just Plain Goose." This is extremely poignant when one considers that most of the later season's episodes focus less on Arthur.
  • Eye Cam: Almost all of "You Are Arthur".
  • Facepalm: A very brief one after dropping the wedding ring in "D.W. Thinks Big".
  • Full-Name Ultimatum: Unlike D.W., he has only ever been issued one once throughout the show in S4's "Arthur's Big Hit", and it is lampshaded.
    Mrs. Read: Arthur Timothy Read, come here!
  • Game Show Appearance: Arthur winding up on in-universe Riddle Quest in S5's "Arthur and the Big Riddle".
  • Guilty Pleasures: Arthur is secretly a fan of in-universe toddler's show "Love Ducks". He keeps it a secret because (per the title of the S4 episode) "That's a Baby Show."
  • Headdesk:
    • He is so exhausted from Pandering to the Base in S1's "Arthur Writes a Story" that he does a Double Headdesk.
    • He does it again in S8's "D.W., Dancing Queen", when he and his friends overhear D.W. tell everyone of his nightmares about his underwear, and even brought it to school for all to see.
  • The Hero: As the title character and de facto leader of his friend group.
  • Hell-Bent for Leather: He wears a leather jacket in S20's "Buster's Second Chance" combined with a Cool Shades version of his normal glasses, in an alternate timeline where he never befriended Buster and became a Tough Customer instead.
  • Heterosexual Life-Partners: With Buster.
  • Hypocritical Humor: He accuses his friends of "not being able to stand a little competition" when playing games with them in "Arthur the Loser". In this episode he resorts to cheating against all of his friends because he proved to be a Sore Loser before his scheme was uncovered.
  • Idiot Ball:
    • "So Funny I Forgot to Laugh" represents such a moment of weakness for Arthur that it's unconvincing.
    • Arthur's cost-cutting ideas in "Arthur Read Super Saver" are more likely to come from the four-year-old-cast, like bathing in water from the Molinas' sprinklers, or trying to cut his family's water bill by getting Pal to lick food stains off the flatware.
  • Jerkass Ball: Happens to him at times.
  • Jerkass Façade: In S20's "Buster's Second Chance", he becomes a Tough Customer in an alternate timeline after befriending Binky instead of Buster... yet he's secretly unhappy with his lot in life and wants someone to share "uncool" hobbies with, like checkers and the in-universe toddler's show "Love Ducks".
  • Kid Hero: Naturally, since he's a 3rd-grader and the main protagonist.
  • Kick the Son of a Bitch: Punching DW in "Arthur's Big Hit".
  • Laser-Guided Karma: Hit with his hard in "Arthur's Big Hit". In that episode, he punches out DW, but Arthur gets punched by Binky later on in that same episode. His parents lampshade it. "Now you know how DW feels."
  • Meaningful Name: Arthur Read. Appropriate, given his love of books.
  • Musicalis Interruptus: The teaser for "That's a Baby Show!" has Arthur demanding a stopdown when Mary Moo Cow and co. randomly show up in his bedroom.
  • Nice Guy: All faults aside, he is usually kind and sweet.
  • Official Couple: He is shown married to Francine in the future on multiple occasions, despite massive denial between each other in S2's "Arthur and the Square Dance".
  • Pinocchio Nose: Has an all-too-obvious habit of fiddling with his glasses when he lies.
  • This Loser Is You: Arthur could be described as this, Depending on the Writer.
  • Took a Level in Jerkass: In S20's "Buster's Second Chance", he becomes a Tough Customer after befriending pre-Hidden Depths!Binky instead of Buster.
  • The Unapologetic: A few times, such as in "Arthur's Big Hit" when he refuses to apologize to DW for punching her, and in "So Funny I Forgot Yo Laugh", where he writes a Backhanded Apology letter to Sue Ellen for making fun of her sweater.
  • Would Hit a Girl: If punching DW in "Arthur's Big Hit" when she broke his model plane is any indication.
  • You're Insane!: Arthur to D.W. after the latter announces plans to live with Mary Moo Cow in S5's "The Last of Mary Moo Cow".

     Buster Baxter 
http://static.tvtropes.org/pmwiki/pub/images/bubu_914.png
Voiced by: Daniel Brochu, Robert Bell (Living Books)

Best friend of Arthur. He and his divorced parents are rabbits.
  • Against My Religion: In S7's "Buster's Amish Mismatch" when he became Amish after a field trip.
  • Agent Mulder: Firmly believes in the existence of aliens.
  • Alliterative Name: Buster Baxter.
  • Amateur Sleuth: One of Buster's trademarks, often imitating hard-boiled Private Detective stories when he's on a case.
  • Badass Biker: Arthur imagines him as one if Buster was a teacher in S8's "D.W., Dancing Queen", complete with Cool Shades, Cool Bike, and a leather jacket.
  • Be Careful What You Wish For: The teaser for "Arthur's Substitute Teacher Trouble" ends with Buster wishing that Mr. Ratburn would disappear. In the aforementioned episode, when Mr. Ratburn loses his voice and has to go on sick day, his class ends up receiving substitute teachers that turn out to be worse at teaching than him.
  • Big Eater: So much so that during a fantasy sequence in S3's "I'd Rather Read it Myself", D.W. imagines him as a robot that only exists to eat. One wonders just how the kid can stay lean. Often leads to Crazy Consumption.
    • This became a plot point in S16's "Too Much of a Good Thing", where Buster has to prove to Arthur he can control his eating habits when a special Girl Scout cookie goes on sale.
  • Book Dumb: Played with; Buster is used to getting F's in class, nearly getting held back a year for it. He has misspelled Arthur's name and once spelled "soccer" with two K's and a Q. However, it is shown in episodes such as "Buster Makes the Grade" that Buster can get good marks when he fully applies himself. His insight outside of the classroom though is usually a case of Depending on the Writer.
  • Clear My Name: "Arthur Accused!"
  • Cloudcuckoolander: Extremely superstitious, and is very, VERY obsessed with extraterrestrial life.
  • Ears as Hair: Buster's mother makes him wear an embarrassing shower cap when he goes swimming, but his ears are more prominent than most, and it would be dangerous to get water inside of them.
  • Eureka Moment: How Buster usually solves his cases. "Overflowing?" "That song!"
  • Expressive Ears: They droop when Buster is upset. "Buster Makes the Grade" is a good episode to watch if you want to see him doing this several times.
  • Failure Is the Only Option: Often has this attitude towards his grades in school, being prone to poor marks due to his lack of focus. Usually Played for Laughs, but in "Buster Makes the Grade" when he risks repeating the third grade, it's treated as anything but.
  • For Want of a Nail: S20's "Buster's Second Chance" reveals that had Buster never befriended Arthur as kids or failed the test that would have let him go a gifted school, Arthur would have met pre-Hidden Depths!Binky instead and become a Tough Customer instead of the Nice Guy he is in the show.
  • Heterosexual Life-Partners: With Arthur.
  • Hypno Fool: In S11's "Buenas Noches, Vicita", one of D.W.'s friends (Vicita) can't go to sleep. D.W. tries several methods, including trying to get Buster to hypnotize her to sleep. A couple of seconds later...
  • It's All About Me: In "Buster Baxter, Cat Saver", where the public's obsession with Buster's alleged "heroism" in rescuing a cat from a tree causes him to abuse his time in the limelight. He eventually got over it after the episode.
  • Keet: He's the most energetic and funniest of Arthur's friends.
  • The Lancer: A position shared with Francine, to contrast Arthur's The Hero.
  • Little Known Facts: Buster will believe anything he reads on the internet, as shown in S9's "Buster the Myth Maker".
  • Meaningful Name: Buster's street address is 7 Roswell Court. An alien spaceship is rumored to have crashed in Roswell, New Mexico.
  • Not So Different: With, of all characters, Mr. Ratburn. They seem opposites in most respects, especially in regards to anything school-related. Buster has a (rather silly) fear of his teacher's love for learning. Despite this, the characters share many other definitive personal tastes. The biggest examples? Both obsessively love desserts, both watch cartoons, and Mr. Ratburn seems to have been much more like Buster in his youth according to what was seen on an old videotape from his high school days.
  • Nerd: His aforementioned obsession with extraterrestrial life.
  • Never My Fault: He's hit with this when he does a history report and intends to open it with a joke for the class, and is furious when Binky beats him to the punch after hearing the joke from Buster earlier. Buster receives a "D" on his report, and openly blames Binky for it until Arthur makes him realize that it's his own fault that he put no effort into the actual assignment.
  • The Pig Pen: Often shown to have poor hygiene; so much so that he was the only student at Lakewood Elementary not to be affected by an outbreak of head lice. Unfortunately, it is not unusual to see him eat stuff off the floor, neglect to wash himself, or display poor table manners.
  • Put on a Bus: S2's "Arthur's Faraway Friend" has Buster leave the show to travel the world with his airline pilot father, which starts the spin-off show "Postcards from Buster". He comes back at the start of S3.
  • Stranger in a Familiar Land: The main plot points of S3's "Buster's Back" and "The Ballad of Buster Baxter".
  • Terrified of Germs: Plot point of S11's "Germaphobia".
  • Unwitting Instigator of Doom:
    • Steals a Cyber Toy in "Nerves of Steal", stuffing it in Arthur's backpack and then must confess when guilt takes over. He not only gets Arthur in serious trouble when they get caught, but he is grounded an entire month with no dessert for his troubles.
    • In one episode he becomes careless with a high-powered telescope he bought to observe the stars, and for this gets a reading suggesting that a comet would hit the earth, eventually causing a panic among his peers. Thankfully, everyone found that the telescope was just missing a piece.
  • Wild Take: In his nightmare in S1's "Arthur's First Sleepover".
  • Your Mom: Told Binky his mother eats gym shorts in one episode. Binky didn't take it too well.

     Francine Alice Frensky 
http://static.tvtropes.org/pmwiki/pub/images/francine_3681.png
Voiced by: Jodie Resther

2nd best friend of Arthur. She and her family are monkeys.
  • Academic Athlete: A mild case. In addition to being a Passionate Sports Girl, she generally makes pretty good grades; Mr. Ratburn has singled out her work as "superb" before, and she was one of Buster's main tutors in "Buster Hits the Books."
  • Aesop Amnesia: In early episodes she would frequently tease Arthur for her own amusement; In "Arthur Makes the Team" she apologizes for this habit to Arthur, only to tell him later that she gets to tease him again if he flunk basketball season.
  • The Ace: Exceptionally good at almost every sport that exists, always has the last word with some witty or sarcastic reply, and is usually the one that ends up having to bail out one or all of her friends in some way or another. She might not be so good at badminton or skiing, if "The Good Sport" is any indication. Once she befriends Jenna, she will play badminton, but previously said it was "for wusses."
  • Added Alliterative Appeal: A book in a bad dream that Francine has is entitled "Francine Frensky: Fraud!".
  • Acquired Situational Narcissism: Happens in "Francine Frensky, Superstar," when Francine gets the lead in a school play.
  • Alliterative Name: Francine Frensky
  • Ambiguously Brown: Many people pictured Francine and her family as being rather dark-skinned or even black, but considering that they're Polish Jews...
  • Art Evolution: In the first few books she wore dresses and her muzzle didn't blend into her face, making it more obvious she's a monkey.
  • Berserk Button:
    • Beating her in anything sports related.
    • "A griffin. A griffin. A griffin..." Note that this was in an Imagine Spot in S1's "Meek for a Week", showing what would happen if Francine kept her anger bottled up for too long.
    • Insulting Hanukkah also qualifies, as seen in the Christmas special.
  • Break the Haughty: Francine has needed a little attitude adjustment from time to time when she gets a little too abrasive.
  • Deadpan Snarker: Has plenty of snark at her disposal.
  • Defrosting Ice Queen: Played with; in earlier seasons she was notorious for her constant teasing of Arthur purely for her own amusement, but as of more recent seasons this bad habit has become far less frequent.
  • Eating Lunch Alone: Muffy lets her take the heat for cheating on a math test in "Arthur and the True Francine". Francine is too despondent to sit with company.
  • Establishing Character Moment: The events described in the following entry take place in the second half of the first episode.
  • Femininity Failure: Francine tries to be feminine for one day, picture day, where she goes to school in a dress and doesn't play kickball during recess so she'll be presentable for her photo. She ends up playing anyway, and being scruffy in the picture.
  • Friendly Rivalry: With the Brain when it comes to sports, as the two are closely matched when it comes to their physical skill. Not always the case though, as seen in "The Big Blow-Up".
  • Heterosexual Life-Partners: With Muffy.
  • Hollywood Tone-Deaf: Subverted by the end of S4's "To Beat or Not to Beat"; she isn't a bad singer, she just can't sing and drum at the same time. Although in later seasons, she would become a much better singer, and her drumming would rarely if ever be mentioned or seen.
  • Hypocritical Humor: Francine often criticizes other people for being mean, despite being a textbook example.
  • Informed Ability: Supposedly she can cook, as seen in "Love Notes for Muffy"; This has rarely been showcased since.
  • It's All About Me: Frequently guilty of this, especially when it comes to her sports.
  • Jerk Jock: She gives off vibes of this, though she's not that bad.
  • Jerk with a Heart of Gold: Depending on the writer, as there are plenty of episodes where Francine is not a jerk.
  • The Lancer: Shared with Buster.
  • Not So Different: Turns out she doesn't like being teased either, as shown in the events of "Draw!" when everyone gives her a taste of her own medicine after she coldly insults Fern. Thankfully this is a habit she does a lot less in later seasons.
  • Official Couple: She is shown married to Arthur in the future on multiple occasions, despite massive denial between each other in S2's "Arthur and the Square Dance". She insisted on doing the rescue scene in "Arthur Makes a Movie" and was keen to play spin the bottle at Arthur's birthday party, possibly in the hope of getting to kiss Arthur.
  • Only Sane Man: Occasionally fills this role, and is more often than not shown to have a good deal more common sense than some of the others.
  • Passionate Sports Girl: Francine is very athletic and loves sports, especially soccer, football, kickball, and bowling. The only sports she doesn't excel at are badminton and figure skating (which she dismisses as "girly"). Francine is very determined, perhaps even restless, and if she doesn't have an immediate knack for a certain sport or skill, she can become frustrated.
  • Prima Donna Director: In S1's "Francine Frensky, Superstar".
  • Plagiarism in Fiction: Francine plagiarizes a school essay in "Francine's Pilfered Paper". While the full range of real-life consequences of plagiarism are discussed, Francine is only asked to repeat the assignment, and she ends up with a lower grade.
  • Slobs vs. Snobs: Between her and Muffy.
  • Sore Loser: One of her longtime trademarks; taken to new heights in "Arthur Calls It", where she berates Arthur for outing Buster in a baseball game in a play that was obscured to most observers and tries to discredit him, all because she was angry they had lost. Taken to an extreme in "The Good Sport", where she lost the Athlete of the Year Award to Jenna that she felt she was entitled to, and goes out of her way to make sure she knows this before finally coming to terms with it.
  • Stock Punishment: The teaser for "Francine's Pilfered Paper" takes place in the Puritan era, and she is punished for plagiarism in this way.
  • Token Minority: Francine's family is Jewish in an apparently mainly Christian community.
  • Tomboy and Girly Girl: Her and Muffy.
  • Tsundere: Comes off as this occasionally, especially towards Arthur.
  • Tyrant Takes the Helm: Main plot point in S1's "Francine Frensky, Superstar". Only after Mr. Ratburn intervened (after what amounted to the entire class sabotaging the play rehearsal) was everything put back into place.
  • We Want Our Jerk Back: Happens in S1's "Meek For A Week"', which nearly caused the group's team to lose a hockey match. They got the jerk back when her Berserk Button was pushed.
  • With Friends Like These...: Her and most of the cast, but it is more prominent between her with Muffy. Sort of goes both ways with Muffy, considering the latter is so often a Rich Bitch, and appears totally clueless as to why Francine doesn't have the same amount of money or cool gadgets that she does—among other things Muffy is clueless about.

     Mary Alice "Muffy" Crosswire 
http://static.tvtropes.org/pmwiki/pub/images/muffy_5037.png
Voiced by: Melissa Altro

Best friend of Francine, since her arrival in 2nd grade. Like the Frensky's, she and her family are monkeys.
  • Aesop Amnesia: Muffy's lessons in selflessness never seem to last more than an episode. Lampshaded in "Muffy's Art Attack", where she tried to take credit for a series of sculptures that were actually handcrafted by Bailey, just as she took all credit for the cookie recipe she and her friends made in "How the Cookie Crumbles"; Francine does not let this go unnoticed.
  • Alpha Bitch: Muffy is often a stuck-up and a complete showoff who does not care to see things from other people's perspectives. She is even cruel to her friends from time to time.
  • Art Evolution: Originally drawn with buck teeth.
  • Big Fancy House: A sign of her unknowingly vast wealth, to the point where it actually has a mini amusement park inside of it.
  • Bitch in Sheep's Clothing: When she was first introduced in the main cast in S1's "Arthur and the True Francine".
  • Break the Haughty: Happens to her semi-frequently.
  • Catch Phrase:
    • "Vomitrocious!"
    • "How rude!"
  • Chain of Deals: Utilizes a small one to get her hands on a World Girl doll in "Cents-less".
  • The Clan: Part of a family that is shown to be influential in the transportation industry.
  • The Fashionista: Mostly in episodes where she has an opportunity to be in other clothes besides her standard dress.
  • Flanderization: Her (claimed) marketing knowledge.
  • Girly Girl: The most traditionally feminine of the main group.
  • Heterosexual Life-Partners: With Francine.
  • Hypocritical Humor:
    • Muffy regularly accuses people of being snobs despite being the textbook example herself.
    • Her catchphrase, "How rude!", usually spoken in a condescending manner or when she herself is doing something most would also consider rude.
  • Intergenerational Friendship:
    • In "The Butler Did... What?", Muffy thought she had this kind of relationship with Bailey. But Francine points out she barely know him personally. To be fair to Muffy, the two are pretty close to one another before she got to know him better by the end of the episode.
    • Later episodes show her trying to have a full version of this with Bailey, though her conversations with him still show shades of ego. For example, Bailey helps Muffy reconnect with her old imaginary friend—but first he has to reassure her she actually has imagination.
  • It's All About Me: Very much, but in later seasons, certain events have mellowed her at different times. For example, she's very upset when she realizes her desire for a bouncy house will result in losing the cherry tree she's had since she was a kid. She also now helps out in a thrift store on occasion.
  • Jerk with a Heart of Gold: Despite her flaws, Muffy has a knack for being friendly, cares a lot about her friends, loves to hang out with them.
  • Large Ham: She can be really dramatic when she wants to be.
  • Lovable Alpha Bitch: She learns from her mistakes and she can be a nice girl.
  • Manipulative Bitch: She will do anything to get her way, even if this means lying.
  • Meaningful Name: Her street address is 1250 Nouveau Lane. Her family is Nouveau Riche, or new money, as explained below.
  • Nice to the Waiter: To her butler/chauffeur, Bailey.
  • Only Known by Their Nickname: Nobody, not even her parents, call Muffy "Mary". Although her mom did give her a Full-Name Ultimatum (Mary Alice Crosswire) in S1's "The Scare Your Pants Off Club".
  • Rich Bitch: She is often labeled a snob and spoiled because of her wealth, condescending attitude and frequent selfishness.
  • Running Gag: Muffy tends to overpack during travel.
  • Slobs vs. Snobs: Between her and Francine. She's the Snob, Francine's the Slob.
  • Sore Loser: While not quite as bad as Francine, she has many such moments.
    • Taken to new heights in "The Election", where she blames Arthur for her losing a class election that didn't award anyone any real power.
  • Tomboy and Girly Girl: Her and Francine.
  • Upper-Class Twit:
    • In S13's "The Great MacGrady", it's shown that she literally does not know how to do dishes. She simply squirts some dish-washing liquid onto the sink full and expects that to do the job.
    • When she learns her family history, she's actually shocked and disgusted when she finds out her family is not akin to royalty, but rather she's descended from commoners and most of her family's wealth comes from her dad's used car business.
    • She thinks that using a credit card is not the same as spending money.
  • Will Not Tell a Lie: In the teaser for "Arthur and the True Francine" Muffy lies to her friends that she has never told a lie. The episode itself shows that she lied about a lot of things when she first came to Elwood City.
  • With Friends Like These...: Her and Francine. A particularly egregious example is in the episode "My Club Rules" where in Muffy basically decides the treehouse isn't good enough for her and that she'll start her own club. Muffy basically begins a chain of everyone acting like jerks to everyone else to go form their own clubs.
  • You Have Got to Be Kidding Me!: This is how Muffy responds when she learns that she has to go without spending money for a whole weekend.

     Alan "The Brain" Powers 
http://static.tvtropes.org/pmwiki/pub/images/brain_promo_1999.png
Voiced by: Luke Reid (first four seasons), Steven Crowder (fifth and sixth season, Arthur's Perfect Christmas), Alex Hood (seventh, eighth and ninth season) Paul Stuart Brown (seasons 9 to 11), James Buckholder (Arthur's Missing Pal), Lyle O'donohue(seasons 12 to 15), Siam Yu (seasons 16 to 18), Max Friedman Cole (season 18-present)

A young bear, and the smartest among Arthur's friends. Not to be confused with that other 90's cartoon character named "The Brain".
  • Academic Athlete: Brain is academically brilliant and great at chess. However, he's also great at basketball and soccer.
  • The Ace: Besides his intelligence, it is shown that he is also good at various sports. He and Francine are often partners for sport-centric episodes. Academics seems to come more naturally to him. Sports, he has claimed that he practices hard for.
  • Ambiguously Brown: Brain is confirmed African-American but doesn't particularly look it since he's a bear. In later seasons, his mother is lighter furred than her son and husband, and is also blonde, meaning the Brain is possibly of mixed race. Then again she had brown hair originally, and as of season 16 is back to that, so it could be dyed.
  • The Bartender: At his parents' ice cream shop in later seasons.
  • The B Grade: Brain gets a B- on a test in S9's "Breezy Listening Blues" and concludes that the breezy listening music his parents recently started playing in their music shop is having a deleterious effect on his studies.
  • Big "WHAT?!": His reaction to his early demise in "Best of the Nest".
  • Black and Nerdy: He's an animal like everyone else — a bear to be exact — but he celebrates Kwanzaa and has relatives in Senegal.
  • Black Best Friend: Brain and Binky seem to be quite close, despite being polar opposites.
  • But Not Too Black: His family's celebrating of Kwanza was the only indication of his race, until an African cousin comes over to visit.
  • Child Prodigy: He is absolutely brilliant. He's written out of "Buster Spaces Out", wherein the other kids need help building and launching a model rocket. Instead, Carl offers to help, and serves as the team's risk assessor.
  • Cloudcuckoolander: Certainly not as much as someone like Buster, but being the most ridiculously smart in the gang he occasionally will overthink and theorize things to ludicrous extremes, which usually just leaves everybody else bewildered.
  • Curb-Stomp Battle: Is easily beaten at chess by the more skilled Rattles in S16's "Brain's Chess Mess".
  • Depending on the Writer: Brain tends to range between The Smart Guy who offers helpful information when needed, a “Stop Having Fun” Guy who pops everyone's bubble, and a Child Prodigy who knows how to casually make things some scientists don't know how to make.
  • Ditzy Genius: He's so smart that he overthinks things.
  • Friendly Rivalry: With Francine when it comes to sports, usually.
  • Insufferable Genius: Can slip into this at times. It becomes a plot point in "Bugged",
  • Meaningful Name: Alan "Brain" Powers. Appropriate, since he's the most intelligent of his group of friends. Also a Punny Name.
  • Mr. Exposition
  • Nerds Love Tough Schoolwork: The only one in class who doesn't groan when given a big homework assignment.
  • No Name Given: It's not really considered appropriate for teachers to address students by their nicknames. Even though it was fudged at first, it was awkward. It didn't become a problem until the TV show began, both because the book narration is from Arthur's perspective and because it is in the third person. Circumstances were such that The Brain had to have a given name, and "Alan" is Adorkable without being difficult to swallow.
  • Not So Above It All: Some episodes, especially later in the show's run, demonstrate that for all his intelligence, Alan is no less prone to bouts of anxiety or irrationality than anyone else. This causes his moments of weakness to appear all the more significant.
  • Only Known by Their Nickname: "The Brain" is only referred to as such by his peers. Only his parents and school staff call him "Alan", his real name.
  • Opening Shout-Out and Internal Homage: The latter of the two is an Episode Title Card, shown in S3's "And Now Let's Talk to Some Kids".
  • Roaring Rampage of Revenge: Goes on one in "Love Notes for Muffy" when she bribes the judges at a science fair; for the most part he just ends up looking foolish for it.
  • Sanity Slippage: Brain is usually the most calm and approachable of all the kids, but when he feels he's been wronged in some way, he'll become darn near psychotic and start giggling crazily, trying to plot revenge.
  • Sesquipedalian Loquaciousness: He was the one working on Antidisestablishmentarianism before the spelling bee in S1's "Arthur's Spelling Trouble".
  • The Smart Guy: A Child Prodigy par excellence.
  • Technobabble: Talks like this a lot, which leaves everyone confused.
  • Token Minority: Brain and his Family seem to be the only major African-American characters in the show, what with Brain's friendship and Arthur and all.
  • Why Did It Have to Be Snakes?: He was afraid to go to a pool party because of his aquaphobia, though later seasons remove it, implying that The Brain got over his fear.

     Shelley "Binky" Barnes 
http://static.tvtropes.org/pmwiki/pub/images/binky_9551.png
Voiced by: Bruce Dinsmore

Another one of Arthur's friends, though also a bully, or once was anyway. He and his family are bulldogs. He plays the clarinet and also dances ballet. He hangs with a group called the "Tough Customers," which has changed its focus since its founding.
  • Adult Fear:
    • In S9's "Binky Goes Nuts", his mother gets worried when he's revealed to have a peanut allergy. Even if the concerns that Mrs. Barnes expresses in "Binky Goes Nuts" seem a bit excessive note  , they are realistic.
    • He goes through this himself when, in S8's "Thanks a lot, Binky", he imagines Rattles messing up a dangerous rollerblading stunt and hurting himself severely, breaking almost every bone in his body. Then his Opinion-Changing Dream shows him what would happen if Binky didn't tell the principal like he did, being stuck in the hospital in a full-body cast in agony until all of his bones were healed.
  • Ambiguously Gay: His Hidden Depths reveal an interest for stereotypically gay hobbies such as theater, dance (especially ballet), art, music, culture, and the likes.
    "I like to read books with lots of pretty flowers. ...Being crushed by a giant pterodactyl!"
  • Art Evolution: In the books his ears were originally drawn flatter on his body and he was fatter.
  • Berserk Button: NEVER speak ill of his mother, unless you want ice cream all over your face.
    Buster: Your mother eats gym shorts!
    Binky: WHAT?!
    (Everyone is aghast at Buster's words as a very angry Binky proceeds to smash his ice cream sundae onto Buster's head)
  • The Big Guy: The biggest and toughest of the main group.
  • Big "NO!": Binky busts out an epic one after a nightmare in S9's "Binky Goes Nuts".
  • The Bully: Moves away from this as the series progresses. Hidden Depths are eventually revealed, which moves towards the Gentle Giant.
  • Character Development: Over the course of the series, he goes from a tough school bully to a Gentle Giant as more of his Hidden Depths are explored.
  • Cool Big Bro: He's very nurturing and helpful with Mei-Lin, his younger adoptive sister.
  • Could Say It, But...: Binky telling Buster how to liberate his confiscated toy car in "Buster the Lounge Lizard".
  • Even Bad Men Love Their Mamas: He may be a school bully, but he dearly loves his mother. That being said, Insult her within earshot at your own peril.
  • Early Installment Weirdness: In "Buster's Back," Binky offers to trade for a peanut butter sandwich. Then he is given a devastating peanut allergy in a later episode.
  • Episode Title Card: Binky blows a bubble gum bubble so big that he is Covered in Gunge when it pops, and he gets stuck in the title card circle.
  • Fat Bastard: A heavy-set elementary student who is a Tough Customer, and a school bully. The early seasons played the trope straight, but as the show revealed his Character Development and Hidden Depths, it became a subverted trope.
  • For Want of a Nail: S20's "Buster's Second Chance" reveals that had Buster not befriended Arthur when they were kids, Binky would become Arthur's friend first, influencing Arthur into becoming a Tough Customer.
  • Freudian Excuse: He admits in one episode that his becoming a bully was due to insecurities from being held back in school.
  • Friend to All Children: While Binky is still a child himself, he befriends D.W. in S3's "The Chips are Down" (to the bafflement of Arthur and friends) and her friend Emily in S13's "The Good, the Bad, and the Binky".
  • Gag Nose: Has the largest nose of the Arthur cast. Marc Brown stated it was inspired by a classmate who bullied him and had a potato-like nose.
  • Gentle Giant: A tall, buff kid with a good heart.
  • Heel–Face Turn: Goes from being a school bully and Tough Customer, to a Gentle Giant who is one of Arthur's close friends. What started it was Sue Ellen standing up to him in S1's "Bully for Binky".
  • Hidden Depths: He's highly cultured and is both a talented ballet dancer and clarinet player. He even admits that being held back has made him very insecure, which led to him becoming a bully.
  • Jerk with a Heart of Gold: Seems to vary from sensitive soul who acts tough to genuinely stupid depending on the writer.
  • Lethal Chef: We find out Binky is this when he tries to make dessert for Christmas dinner at a soup kitchen. His attempts include pecan pie with shells and banana bread with peels. Perhaps most egregiously, he forgets to add sugar to his brownies.
  • Named After Somebody Famous: His great-grandfather, Shelley Barnes.
  • Names to Run Away from Really Fast: Played straight and subverted; as the school bully, his name used to strike fear into the kids at Lakewood Elementary. But then when you remember that "binky" is another word for pacifier, it loses this.
  • Odd Friendship: With D.W., ever since S3's "The Chips Are Down". Arthur and his friends are left completely baffled by this.
  • Only Known by Their Nickname: S15's "What's in a Name" reveals that Binky is indeed not his real name. It is, in fact, Shelley, named after his great grandfather. Not only do his parents not call him this, even Binky himself, didn't know.
  • Real Men Wear Pink: Sleeps with a night light and takes ballet classes. Seems the longer the series continues, the less he tries to hide it. Heck, his shirt is even sort of pinkish-orange!
  • Suspiciously Specific Denial: In S9's "D.W., Dancing Queen", when Rattles and Molly catches Binky teaching D.W. how to dance (for a school project) and confront him about it, he says he's teaching her martial arts. They buy it.
  • Unmanly Secret: Zigzagged like crazy. When his character first starts developing unmanly interests, he tries to hide them, but then gets found out anyway. Though some people try to make a big deal of it at first, his perceived fierceness and reputation as a bully allows him to quell any teasing or bullying simply by growls, posturing and death glares. In later seasons, he still sometimes tries to hide it, but just as often is open about it. In Season 15's "I Wanna Hold Your Hand," he doesn't care one bit that his friends in the Tough Customers gang know that he's going to be performing in a clarinet solo, but is terribly afraid that one of them might find out that he still sometimes holds his mother's hand. When they do find out anyway, they chew him out... for not having a juicier, more embarrassing secret!
  • We Want Our Jerk Back: Happens to Binky occasionally.
  • Why Did It Have to Be Snakes?: A focal point in S2's "Night Fright", as Binky can get really scared in the dark.

     Sue Ellen Armstrong

Voiced by: Patricia Rodriguez (s1 - s8), Jessica Kardos (s9 - present)

Arriving in the show in 3rd grade, she and her family are cats. Her father is a diplomat, and her family travels to different countries due to his job.
  • Action Girl: Shown to the skilled in martial arts, particularly Tae-Kwon-Do.
  • Carnivore Confusion: Sue Ellen is a cat. Ratburn is a rat. But they seem to get along fine. There's some sort of humor in the cat character being the vegetarian.
  • Cats Are Mean: Averted, as she is one of the kindest people in Arthur's group of friends.
  • The Determinator: Usually a force to be reckoned with once she's set her mind to something; In one episode, she's the only one in the class with the nerve to protest the near-closure of the Sugar Bowl. She was also the first kid to stand up to Binky, eventually prompting him to steer away from bullying.
  • Everyone Hates Math: Apparently, Sue Ellen and her parents aren't that good at math; when it comes time to measure things, they manage by using estimation.
  • Girlish Pigtails: She wears a pair of them on each side of her head, except they're bunched up and curly.
  • Granola Girl: She becomes one in S8's "Sue Ellen Chickens Out". "Sue Ellen Vegges Out" gives her another level of this, when she decides to become a vegetarian after befriending a pig at a farm she visited. note 
  • Nice Girl: One of Arthur's nicest friends.
  • Only Child Syndrome: Main plot point in S2's "Sue Ellen's Little Sister". Come to the point where she spends time with D.W. however...
  • Only Sane Woman: Occasionally fills the shoes of this role.
  • Ship Tease: S2's "Sue Ellen's Lost Diary" hints that Sue Ellen may have a crush on Arthur, following a debacle with her diary. This is a throwback to the book "Arthur's Valentine" where Arthur has a crush on the new student (Sue Ellen).note 
  • Sixth Ranger: Not always in the main group, but important whenever she is.
  • Sophisticated as Hell: A downplayed example, but being the daughter of a diplomat and having lived all over the world, she is well-read and is pretty much the class expert on exotic cultures.
  • Tomboy and Girly Girl: Plays the tomboy to Fern's girly girl on occasion.

     Fern Walters 
http://static.tvtropes.org/pmwiki/pub/images/fern_8114.png
Voiced by: Holly G. Frankel

Originally a background character, she and her family are dogs.
  • Amateur Sleuth: Fern, like Buster, has this as one of her trademarks. In sharp contrast to Buster though, Fern prefers classic novelized detectives like Sherlock Holmes, Hercule Poirot and Miss Marple, sometimes imitating any of them when she's on a case.
  • Ascended Extra: Until S1's "I'm a Poet", she was a relative Living Prop. Lampshaded by Francine once Fern is finally driven to speak after a pushed Berserk Button courtesy of Binky.
    Francine: That's the most she's said all year!
  • Berserk Button: Don't insult her hobbies.
  • Beware the Nice Ones: Francine and the Brain find out first hand in S2's "Draw!" and S12's "War of the Worms" respectively.
  • Cloudcuckoolander: Not to Buster's extent, but still pretty out there.
  • Episode Title Card: A shot, taken from S10's "Fern and Persimony Glitchet", that shows her writing. The difference between the other, louder title cards is symbolic of her quiet nature.
  • Jitter Cam: The intro to "Fern's Slumber Party". This does not help Fern at all.
  • Let's See You Do Better: Fern dares her classmates to put up or shut up when they insult her hobby.
  • Nerd: She is a Mystery Novel Fangirl, being shown in S2's "Fern's Slumber Party" playing with a Sherlock Holmes action figure. S11's "Phony Fern" even has her (and George) role-playing as Hercule Poirot.
  • Nightmare Fetishist: Along with mysteries, Fern is very fond of reading and telling scary stories. She's also known to enact scary pranks on people, or imagine terrible things happening to people while she smiles about it.
  • Shrinking Violet: As the show progresses, she becomes more out-going and socializes more, though she still retains a bit of shyness.
  • Sixth Ranger: Not a part of the main group, but still an occasional friend.
  • Tomboy and Girly Girl: Plays the girly girl to Sue Ellen's tomboy on occasion.
  • Unaccustomed as I Am to Public Speaking...: Her mom makes her throw a slumber party to improve her confidence. When it works, Fern's mom gloats a little to the audience.

Voiced by: Tamar Kozlov (TV series), Wendee Lee (Arthur's Missing Pal), Bianca Rasmussen (Living Books)

One of the few 4th graders in the show, she and her family are either poodles or rats (official sources disagree).
  • Alpha Bitch: During the earlier seasons. She mellows out a bit once Henry Skreever and Marina Datillo are introduced to the show in S6's "Prunella's Special Edition".
  • Big "NO!":
    • She screams it in the opening of S6's "Prunella's Special Edition", when she discovers that her new book is printed in Braille, and she can't read it.
    • Prunella screams it in "Prunella Packs It In", when she dreams that she is in college run by the clown.
    • She screams in "Prunella in the Haunted Locker", when she dreams she was attacked by her locker.
  • Episode Title Card: I PREDICT THAT YOU WILL SHORTLY SEE... (episode title read out loud), taken straight from S4's "To Beat or Not to Beat".
  • Hair Decorations: Wears a bow in her hair.
  • Heterosexual Life-Partners: With Marina. Occasionally, Muffy would fill this role.
  • Nerd: Earlier seasons would show that Prunella and her sister Rubella were obsessed with paranormal phenomena. Her massive love for Henry Skreever would later become one of her signature character traits.
  • Phony Psychic: Just like her big sister. Oddly, she still believes her sister even though she's using the same tricks.
  • Sixth Ranger: She's a grade higher than most of the rest of the cast, so she only hangs out with them on occasion.
  • Yet Another Christmas Carol: She goes through one in S4's "Prunella Gets it Twice". Lampshaded when the "Ghost of Presents Past" interweaves Tiny Tim into the story.

     Marina Datillo

Voiced by: Helena Evangeliou

Prunella's friend, also a fourth-grader, who presumably goes to school at Mighty Mountain. Prunella met her in "Prunella's Special Edition" and she's been a recurring character ever since.
  • Academic Athlete: Marina is a bookworm who's also great at gymnastics and yoga. In a brief scene, she's shown playing soccer at school.
  • Inspirationally Disadvantaged: Averted. Marina is blind, but does not like people to make a big deal of it. She's also received a massive amount of Character Development that's unrelated to her disability, which is somewhat unusual for a kids' show.
  • Nerd: She and Prunella share a deep love of Henry Skreever novels, and both enjoy paranormal phenomena.
  • Satellite Character: She is defined entirely by her relationship with Prunella.

     Lydia Fox 
Voiced by: Barbara Mamabolo

An eponymous fox and friend of the third/fourth grade cast who was introduced in later seasons.
  • Academic Athlete: We first encounter Lydia as a new friend of Brain; they met because an injury relegated him to a wheelchair during basketball season. Through this, we find out Lydia is a great basketball player, but is also highly intelligent and plays a mean game of chess. Additionally, she's great at twirling batons.
  • Handicapped Badass: She may be in a wheelchair, but she's good at basketball.
  • Inspirationally Disadvantaged: Averted. She uses a wheelchair, but it's not her only characteristic, and she's quite opposed to being given sympathy based on the wheelchair alone.
  • Retcon: She originated as the winning character of a kids' contest, where her submitted name was Lydia Fox. When the official episode was made, she was never given a last name in dialogue. However, she got the full name Lydia Gordonnote  in the episode's credits. When she returned a few years later, the name Lydia Fox was canonized through in-episode dialogue.
  • Tomboy and Girly Girl: Plays the tomboy to Muffy's girly girl in "Little Miss Meanie" from Season 18.

     George Lundgren

Voiced by: Mitchell Rothpan (s1 - s7, APC, AIO Rn R), Evan Smirnow (s8), Eleanor Noble (s9 - s11; s14 - present), Samantha Reynolds (s12 - s13)

Originally a minor character in the background, he is a moose; a rare sight in the show. He is a young boy who has special talent in wood-carving and building, and is a skilled ventriloquist. He is often accompanied by Wally, his giraffe dummy.
  • The Announcer: Takes up this hobby in "Baseball Blues".
  • Adorkable: George is incredibly awkward around other people (in part because of his horns), and spends less time talking to living people than he does to his ventriloquist's dummy, Wally, which he made himself.
  • Ascended Extra: Though George existed since the beginning of the show, it was quite a long time before he was made into a full-fledged character, in S3's "Arthur's Dummy Disaster". Since then there have been more George-centric episodes.
  • Big "NO!": Three instances:
    • S8's Desk Wars, when his bubble-gum stegosaurus model is destroyed.
    • S9's George Blows His Top, when Arthur asks him if George can tell him the time. He replies, "NO!! What is it with you people? GET YOUR OWN WATCH!!"
    • S14's "Follow the Bouncing Ball", where his painstakingly arranged dominoes are knocked over by Francine.
  • Butt Monkey: He is often the subject of Binky's bullying in the earlier seasons prior to his characterization. Once he becomes more important, he still frequently gets forgotten or ignored by his friends.
  • Consulting Mister Puppet...Who is regularly poached for advice.
  • Forgettable Character: Initially nobody could remember him. It's gotten better recently, but still occasionally comes up.
  • "L" Is for "Dyslexia": Although the original portrayal is closer to Attention Deficit... Ooh, Shiny!.
  • Mr. Imagination: Has many imagination sequences.
  • Mysterious Protector: This is George's entire relationship with his classmates, until they get to know him.
  • Only Sane Man: On occasion; a notable example is "Do You Speak George?" when everyone insists on speaking only their own made up languages.
  • Sixth Ranger: The main group frequently forget he even exists, so he only tags along on occasions.
  • Truth in Television: Students with disabilities can submit exams and assignments in an alternate format, if they have documented their disability in advance.
  • Ventriloquism: With Wally.

     Carl Gold 
Voiced by: Dwayne Hill (s13), Dylan Hoerner (s14 - present)

A young male rabbit who befriends George in season thirteen, and is later introduced to George's classmates. Carl has Asperger's Syndrome.
  • Anything but That!: The first time that Carl sees Wally, he starts to hold his head and panic. By the time of "Carl's Concerto," he's over it, though.
  • Child Prodigy: In "Buster Spaces Out", Carl is able to easily serve as a risk assessor for Buster's model rocket launch, filling in for an indisposed Alan.
  • Inspirationally Disadvantaged: While the writers are usually very good about avoiding this trope, Carl's role in "He Said, He Said" is a Type B example. Carl is able to remember the events of a Bionic Bunny special better than Arthur, Buster, or George can.
  • Long Speech Tea Time: George gets Carl going on a monologue about trains. Since George can't get Carl to stop, it turns into the framing device for the story of how they met.
  • Photographic Memory: Implied in a couple of episodes.
  • Rail Enthusiast: Carl has books about trains, loves to put together train puzzles, and keeps a journal of train illustrations.
  • Satellite Character: Played with. Carl initially meets George, and meets his other peers later. While he does try to get along with the other kids, George still acts as an intermediary for them sometimes. In a straight example, Carl's mom only ever appears to support Carl himself.
  • Spell My Name with an "S": Closed captioning spells Carl's surname as "Gold," but Arthur Wiki spells it as "Gould".

     Jenna Morgan

Voiced by: Brigid Tierney

Another former background character in Arthur's class, she is a cat, entirely different from Sue Ellen though.
  • The Ace: It is mentioned that Jenna is also good at sports, mostly at the ones Francine is not good at.
  • Ascended Extra: Like George, it was quite a while before she became a character with a personality. Despite having only one episode with her as the main focus in the show's 15 seasons (S7's "Jenna's Bedtime Blues"), she is maintained as a prominent secondary character.
  • Embarrassing Damp Sheets: In "Jenna's Bedtime Blues", she is revealed to have this problem.
  • Informed Ability: In S6's "The Good Sport" we're told that Jenna excels in a number of sports that it's hard to imagine her doing. This seems like a one-off joke at first, but later episodes actually show her playing those sports.
  • Irony: A cat who's allergic to milk.
  • Mauve Shirt: She has gotten a few spotlight episodes, but much less than the rest of the cast, and still generally remains underdeveloped. She is eventually depicted as Maria's confidant in "Maria Speaks."
  • Out of Focus: Jenna has only spoken a few times since season 9.
  • Why Did It Have to Be Snakes?: Jenna's reluctance to put on her pull-ups as shown in her only focus episode, S7's "Jenna's Bedtime Blues".

     Ladonna Compson

Voiced by: Krystal Meadows

The Compsons are a family of rabbits with tan fur. They moved from Louisiana to Elwood City in the Season 16 premiere, "Based on a True Story". Ladonna is the third of four siblings. She has a penchant for oral storytelling, similar to Fern's love of poetry, or Sue Ellen's journaling hobby.
  • Big Eater: So much so that her father calls her a "garbage disposal with legs". The only thing she won't eat is beets.
  • Bunnies for Cuteness: Quite a good-looking rabbit.
  • Cool Big Sis: She has her moments, particularly during "Adventures in Budylon." She steps up to teach Bud how to tie shoelaces.
  • The Friend Nobody Likes: Downplayed. Ladonna's tendency to tell tall tales makes her the most likely of Arthur's friends to upset everyone else, especially when she first moves into town. The forthcoming episode "Ladonna's Like List" explores the concept of. Ladonna's likeability.
  • Genki Girl: Is quite the chatterbox and can be rather chipper at the right times. Especially when snowy season comes around, as seen in "Waiting for Snow"; Ladonna squeeing in excitement becomes a Running Gag in the episode.
  • Motor Mouth: Initially introduced as such, telling tall tales in the hopes of impressing her would-be friends.
  • Stock "Yuck!": She can't stand beets; just looking at beets upsets her stomach.
  • Trademark Favorite Food: Cake, King cake in particular.

     Maria Pappas 
Voiced by: Stacey Depass

A background character frequently seen as a member of Mr. Ratburn's class; she is a rabbit.
  • A Day in the Limelight: "Maria Speaks", her first speaking role to date.
  • Friend to All Living Things: So much so that she is able to talk perfectly fine when speaking to animals.
  • Ascended Extra: One of the most recognizable background characters, it was not until Season 19 that Maria was actually given either a name or an actual speaking part. While far removed from being a main character, she is never far out of view at Lakewood Elementary.
  • Bunnies for Cuteness: Probably a big part of why she stands out despite being in the background.
  • Heterosexual Life-Partners: In a loose sense, as Jenna seems to be the only person Maria is otherwise able to confide to under normal circumstances.
  • Out of Focus: More so than any other character before her first lead role in Season 19.
  • Shrinking Violet: She desperately tries to hide her stutter from the rest of her classmates.
  • Speech Impediment: We find out that Maria suffers from a chronic stutter; with a little help however, she is slowly overcoming it.
  • The Voiceless: Until Season 19, she was this. So much so that Arthur can't remember ever hearing her speak.

     The Tough Customers 
"We're not bullies. We're kids who have a hard time expressing our emotions in a constructive manner." - Rattles

The Tough Customers are a gang of bullies at Lakewood Elementary School, founded by Binky, who is the one member who is not in the fourth grade. In "Arthur's Big Hit", Binky decides to get rid of the club, but in later episodes the club is still there. They hang out on the jungle gym (aka: The Tower of Pain), and also have an entire lunch table reserved for themselves. In early episodes, especially Season One and Two, they were portrayed as malevolent malcontents, but this lessened as time went on. Initially, there were many members, including Binky, Rattles, Molly, but the core three are the only of the original club to remain: none of the others are seen very frequently after Season Four. Later, Molly, Rattles, and Binky are joined by Slink, who was previously just a one-shot character from an earlier episode. From then onward, those four are consistently portrayed as the entirety of the group.
  • Aerith and Bob: Molly, Rattles, and Slink?
  • Affectionate Nickname: It's subtle, but Rattles often refers to Molly by "Moll" rather than her actual name. Both of them refer to Binky as "Binks" on several occasions.
  • Blue and Orange Morality: Due to their extreme displays Hypocritical Humor. In one episode, Arthur proclaims that he's a thief to gain acceptance to their group, and they openly welcome him and congratulate him on his "art." Then when it's revealed he wasn't honest, Binky and Rattles berate him for lying.
  • Character Tics: Frequently and consistently seen with their rollerblades and skateboards.
  • Character Development: They're introduced as a Gang of Bullies of sorts, but they slowly reveal their nicer and more sensitive sides during the series. As of "The Last Tough Customer", they decide to abandon their bullying ways altogether.
  • Characterization Marches On: They become less obvious bullies and just kids who can sometimes be thoughtless and mean. They also channel their energy more constructively, going from malicious bullying to consumer advocacy.
  • Depending on the Writer: Whether they're actually legitimately malicious or just rougher and tougher than most of the other students.
  • Diminishing Villain Threat: In early seasons, they're truly nasty and unkind to other students. By Season Eight, the worst they do is claim the jungle gym for themselves and bar everyone else from playing there, and occasionally throw water balloons at other students. By S16's "The Last Tough Customer", they decide to abandon their tough act altogether.
  • Even Bad Men Love Their Mamas: Binky and Rattles play it straight, with Binky's Berserk Button involving insults about his mother . Molly is a gender-inverted example.
  • Everyone Has Standards: When they realized they might have unintentionally hurt Pal in "Arthur Cleans Up", they look notably dismayed and upset.
  • For Want of a Nail: In S20's "Buster's Second Chance", both the Tough Customers' evolution into bullies with softer sides and Hidden Depths, and their eventual disbandment as a group in S19 depended on Buster befriending Arthur. If Buster hadn't done so, they would have continued to terrorize Elwood City.
  • Gang of Bullies: As close as they could get on Arthur, anyway.
  • Go-Karting with Bowser: Binky hangs out with Arthur and his friends on a regular basis, and Molly and Rattles can be seen doing the same in "Don't Ask Muffy" and "Bugged".
  • Hidden Depths: All of the Tough Customers have this, especially Rattles, Molly, and Binky.
  • Jerk with a Heart of Gold: As quoted by Rattles above, all of the Tough Customers are deep down, very nice people with personal hobbies they enjoy, and even help out Arthur and his friends on multiple occasions (especially Binky, who hangs out with them as well as D.W. regularly). They just don't know how to express themselves in a more socially acceptable manner other than acting tough. By S16's "The Last Tough Customer", they avert it by dropping their bullying ways and shape up.
  • Local Hangout: The jungle gym, which they call the "Tower of Pain". Oddly enough, they can be frequently found at the library, as seen in "Sue Ellen's Lost Diary" and "Arthur Makes Waves". They also make the Sugar Bowl their hangout in S20's "Buster's Second Chance" in an alternate timeline where Buster didn't befriend Arthur.
  • Meaningful Name: On one hand, Rattles and Binky are named after children/infant toys and objects, suggesting they really aren't as tough as they appear. On the other hand, we have Molly, whose name means "bitter", and Slink, a term to describe a quiet, stealthy walk.
  • Metal Head: Molly, Rattles, Slink, and maybe Binky.
  • No Name Given: A few of the Tough Customer "extras" have names, like the male cat named Kieper, the female cat named Fletcher, and the male bear named Billy, but others remain unnamed such as a male dog, a male rabbit, and a female aardvark.
  • Not Evil, Just Misunderstood: What Rattles claims he and his friends are in S14's "D.W., Queen of the Comeback", as quoted above.
  • Pet the Dog: In S8's "D.W., Dancing Queen", both Molly and Rattles step up to help D.W. with her ballet performance when Binky twists his ankle and is unable to dance onstage with her.
  • Real Men Wear Pink: Especially Binky and later Rattles, but all of them dance ballet at some point. Binky, Slink, Molly, and Rattles all take part in a barbershop routine for the Summer Serenade in "D.W. Beats All".
  • Soapbox Sadies: Downplayed. They go from bullying their schoolmates to picketing businesses to protest problems like extortion and unhealthy fast food. They usually don't overshoot it, though.
  • School Bullying Is Harmless: Sometimes.
  • Tomboy: All of the girls.
  • True Companions: In spite of their faults, they stick by one another and help each other out, as seen in Seasons Eight and Nine. For example, in S8's "Binky Goes Nuts", when it was discovered that Binky was allergic to peanuts, Molly acted as bodyguard and prevented students with said food from sitting near him in order to preserve his health.
    • They also helped Rattles get along with his new twin step-siblings, even giving him a slang dictionary so he can understand his step-sister's lingo better.
  • Villains Out Shopping: Rather hilariously, Molly and Rattles can be seen at the front of the crowd at the meeting for concerned citizens in "The Scare-Your-Pants-Off Club".
  • Younger Than They Look: They can all pass for high schoolers due to their punk/grunge-like outfits, even though they're about as young as Arthur and his friends.

     Molly MacDonald

Voiced by: Maggie Castle

A fourth grade rabbit and one of the Tough Customers. She has a younger brother named James, who is friends with D.W.
  • Action Girl: The only female Tough Customer to remain and the only main female skateboarder.
  • Aloof Big Sister: Averted. One might think she would be this, but she is close with James.
  • Alliterative Name: Molly MacDonald
  • Ascended Extra: She started off as a generic bully girl in the Tough Customers, but later episodes gave her a Morality Pet in the form of her younger brother, a hidden creative side, a more relaxed personality (in comparison), and an overall more sympathetic presentation.
  • The Atoner: Becomes this in S19's "The Last Tough Customer" when she realizes that James is adopting her bullying ways, and decides to try turning a new leaf.
  • Berserk Button: If anyone tries to take the "Tower of Pain" from her, as seen in "The Law of the Jungle Gym".
  • Blinding Bangs: Her eyes have only been seen very briefly in a few episodes, such as "Agent of Change" and "Arthur, World's Greatest Gleeper".
  • Cool Board: Her skateboard is black and wrapped with barbed wire around the middle.
  • Cool Big Sis: When James needs help, he goes to Molly.
  • Defrosting Ice Queen: Over the course of the series, though not especially evident. Most apparent in "Arthur Makes Waves".
  • Drill Sergeant Nasty: When coaching her younger brother for his swim meet.
  • Even Evil Has Loved Ones: She's very close to her little brother James, despite her tough act. When James Took a Level in Jerkass just by watching her, Molly has a Heel Realization and resolves to reform herself for his sake.
  • Expository Hairstyle Change: During her Start of Darkness, she changes her bun to her current tomboyish bob after she is bullied.
  • Fiery Redhead: Her hair's more a reddish-brown, but she acts like this on occasion, often when she gets lines.
  • Forbidden Friendship: With Arthur, prominently in one episode, though they keep it a secret due to their respective friends' disapproval. Though the writers seem to have forgotten about it, the shippers have not.
  • For Want of a Nail: S20's "Buster's Second Chance reveals that she would still remain a bully and Tough Customer had Buster not befriended Arthur at the fated sandbox.
  • Freudian Excuse: She was bullied a lot when she was younger, her classmates tormenting her by calling her "Muffin Head" and destroying her sandcastles. The experience hardened her heart and made her act tough, and in time she became a bully herself.
  • Heel Realization: "The Last Tough Customer" is this for her after seeing James picking up her bully habits.
  • Hidden Depths: She cares a great amount for her brother and Mom, is interested by storytelling and animation techniques, and is concerned by the lack of independent female characters in media.
  • Implied Death Threat: We don't hear what she said to Muffy in "The Law of the Jungle Gym", but even the other Tough Customers thought she went too far.
  • Important Haircut: Her hair used to be longer and put up in a bun right on top of her head when she was in preschool. But after she was bullied, she let her hair loose and transformed into her current bob in an attempt to adopt a tougher image.
  • Jerk with a Heart of Gold: Once took great pride in her bullying ways, but deep down is a well-meaning and somewhat insecure girl.
  • Just Friends: With all of the male Tough Customers, as well as Arthur.
  • Kick the Dog: In S16's "The Last Tough Customer", she cruelly pokes fun at George's dyslexia, causing the boy to run off and cry. Even Binky, who regularly picks on George thought that wasn't okay.
  • Lean and Mean: Perhaps it's just because she's older and taller, but she's noticeably thinner than the main cast. This is especially apparent when she's standing next to the male Tough Customers, who are more stocky and muscular than her.
  • Malicious Misnaming: "Muffin Head", due to how her bun was put right on top of her head when she was a preschooler.
  • Meaningful Name: Her first name means "bitter", which certainly suits her malicious personality in the early seasons. The derivation of her surname is from the Gaelic "Mac Dhomhnuill", translating as "The son of Donald". It is said that the personal name "Donald" translates as "world-rule". Molly is a bully who rules the playground.
  • Morality Pet: Her younger brother James is one for her, and she decides to change her ways when she sees him repeating her mistakes.
  • Masculine Girl, Feminine Boy: Compare her distinct lack of traditionally female interests and her rough-and-tough appearance to Binky's activities.
  • Not So Above It All: In "Arthur Makes Waves", she discovers she has a lot in common with Arthur after she stops trying to act cooler than him all the time.
  • Odd Name Out: She has a normal name compared to Rattles, Binky, and Slink.
  • Off Model: At some points in early episodes, her Blinding Bangs are shorter than usual, but her eyes don't show at all, giving the impression she has no eyes.
  • One of the Boys: To the extent of some Viewer Gender Confusion, as her demeanor and activities barely portray a hint of femininity.
    • At one point, the male Tough Customers imagined her in a dress and were weirded out by the very idea.
    • She took part in a barbershop quartet with Binky, Slink, and Rattles. All four wore traditional male barbershop costumes.
    • In an Imagine Spot of 50's society, Arthur and his friends are shown wearing gendered clothing, letterman sweaters for the boys, poodle skirts for the girls, while the Tough Customers are depicted as greasers. Molly is wearing a dark leather jacket and jeans right alongside her male friends.
  • Pet the Dog:
    • In "Law of the Jungle Gym", she can be seen several times being kind to a stray cat.
    • She is often very kind to her younger brother, and much more patient with him than Arthur is with D.W.
    • When other students come to her for advice, she tells them her best ideas and takes time to talk with them even though she would rather be skateboarding.
    • "The Last Tough Customer" is one giant moment for her combined with The Atoner, Heel Realization, and Heel–Face Turn.
  • Pint-Sized Powerhouse: A subtler example than most, but when she is arm-wrestling with Binky, she gives as good as she gets even though he's taller, heavier, and stronger than her.
  • Platonic Life Partners: As of Seasons Eight and Nine, Molly and Rattles are almost never seen apart, even for mundane activities such as walking the dog, or special occasions such as dancing ballet together.
  • Positive Discrimination: She is depicted as the most intelligent, capable, and, besides Binky, sympathetic Tough Customer, and though she still remains tough, her bullying of other kids is less and less prominent in later seasons.
  • Sleeves Are for Wimps: A rare female example. Molly is almost always seen wearing a denim jacket as a shirt with ragged edges from ripping off the sleeves.
  • Sibling Yin-Yang: Tough, confrontational Molly and her quiet, unassuming younger brother James.
  • Spell My Name with an "S": It's MacDonald, not "McDonald".
  • Start of Darkness: Turns out she was a victim of bullying herself. Seeing James start to repeat the pattern prompts her Heel Realization.
  • The Stoic: As a result of her Blinding Bangs that hide her eyes, it's difficult to gauge her emotion when she isn't speaking.
  • Tertiary Sexual Characteristics: Mostly absent. The only physical indication of her gender is her bob, but that helps little when she's standing beside fellow Tough Customer Slink, who is male and has hair that's longer than hers.
  • Those Two Bad Guys: While she often initially appeared in the background of some scenes along with other Tough Customers, Season Five onwards seems to be going forward with this route for her and Rattles.
  • Tomboy: Out of all the girls on the show, Molly is probably the quintessential example. Binky had to convince her to dance ballet by telling her it was a new martial arts style. Undoubtedly the most aggressive female character on the show, even after her Character Development.
  • Used to Be a Sweet Kid: She was a sweet little girl until she became a bullying victim in preschool. After that, she became a Tough Customer.
  • Women Are Wiser: From Season Eight onwards, most episodes featuring the Tough Customers portray her as the most level-headed and realistically-minded of the group.

Voiced by: Scott Beaudin (s14 - present)

A fourth grader who seems to alternate between being a cat, a dog, and a bear.note  Another one of the Tough Customers.
  • Beware of Vicious Dog: He owns a mean, snarling dog, aptly named "Crusher." Said dog later becomes nicer due to the influence of Grandma Thora's dog Killer, and Francine's cat Nemo.
  • Book Dumb: He has an extensive vocabulary, but has trouble spelling, as seen in "The Play's The Thing".
  • Calling Me a Logarithm: Inverted. He uses words he doesn't know to insult people, such as "bibliophile" and "philanthropist".
  • Cats Are Mean: As stated above, he alternates between being a cat, dog and/or bear, though he's still not very nice either way.
  • Cool People Rebel Against Authority: Played straight with him most of the time, but he is occasionally shown to have a certain degree of respect for those in charge.
    Rattles: (Protesting the idea that Mr. Ratburn would wear socks with holes in them) Mr. Ratburn wouldn't wear no sock full of holes! He's a very upstanding kind of guy.

    Rattles: (Upset when someone puts trash in the recycling bin) Yo! It's paper only! Can't you read?!
  • Curb-Stomp Battle: He won his chess match against Brain in S16's "Brain's Chess Mess" pretty quickly.
  • Dark is Evil: A bully and one of the only two kids to have a recurring black article of clothing (in his case, a black jacket he constantly wears). However, it's also subverted in later seasons, where he reveals himself to be a decent guy underneath his tough image, with hobbies of his own.
  • A Day in the Limelight: S19's "Whip, Mix, Blend.", where he deals with his mother's divorce and remarriage, and learning how to live with his twin step-siblings.
  • Hell-Bent for Leather: His dark jacket resembles one of these.
  • Hidden Depths: He's a very skilled chess player, enough to teach Brain's Chess Club how to play better, and likes knitting and sewing. His vocabulary also includes words that are above his school grade. In S16's "Brain's Chess Mess", he declines Brain's offer to do his homework in return for joining the Chess Club, on the reason it'll "deprive [Rattles] of his education."
  • Hypocritical Humor: Yells at a guy for tossing regular trash into a paper-only recycling bin, minutes before intimidating some random children into giving their ice cream to him and Molly.
  • Jerkass: Probably the most consistently antagonistic of the Tough Customers. He becomes nicer in later seasons, though.
  • Jerk with a Heart of Gold: Despite his tough, bullying ways, he's still an okay guy deep down.
  • Joisey: His voice in later seasons has shades of this.
  • Names to Run Away from Really Fast: If his name refers to "Rattles" as in "Rattlesnake," he fits this. If it's the other kind of rattle, then not at all.
  • Nice Hat: He is almost never seen without his red baseball cap, always worn backwards.
  • Not Evil, Just Misunderstood: He doesn't see himself as a bully, and took offense at being called one by D.W. in S14's "D.W., Queen of the Comeback".
  • Not So Different:
    • With Arthur towards the end S14's "Arthur Unravels" - turns out he likes knitting, too, but kept it a secret from the other Tough Customers. His response to Binky, Molly, and Slink looking at him in surprise after Dr. Fugue outs him as a member of his knitting club, is to shrug and smile sheepishly as if to say, "Guilty as charged."
    • Seasons 14 and 16 reveal that he also has a food allergy just like Binky, except in his case he's lactose intolerant.
  • Off Model: He had a dark brown tuft of hair in early seasons, but after Season 8, it was changed to light gray to match his skin.
  • Pet the Dog:
    • As mentioned in the Tough Customers' folder, he and Molly help D.W. with her school ballet project after Binky twists his ankle.
    • He also tries to help D.W. come up with good comebacks against the Tibble twins in S14's "D.W., Queen of the Comeback", even though he personally thinks the kids' vendetta is ridiculous and initially suggests to D.W. that she ignore the Tibbles.
  • Platonic Life Partners: As of Seasons 8 and 9, Molly and Rattles are almost never seen apart, even for mundane activities such as walking the dog, or special occasions, such as dancing ballet together.
  • Playing Sick: He fakes a stomachache on the day of a chess tournament in S16's "Brain's Chess Mess", as part of a gambit to get Brain to play against a particularly hard opponent without his help, because he had faith Brain can do it. It works.
  • Plot Allergy: Seasons 14 and 16 reveal that he's lactose intolerant.
  • Real Men Wear Pink: His interests include sewing and knitting.
  • Recurring Extra: He can often be seen in background scenes, more so than any of the other Tough Customers.
  • Sophisticated as Hell: He often makes quite eloquent and mature remarks, but they end up sounding a bit ridiculous due to his exaggerated Joisey accent that makes his voice seem a bit thuggish, and his lack of knowledge in regards to what the words actually mean.
  • Stock Foreign Name: His surname is "Ciccone", suggesting he is of Italian descent.
  • That Liar Lies: In S1's "Arthur, World's Greatest Gleeper". After he learns that Arthur lied about being able to gleep, he responds with a tirade that ends with "lying lie face".
  • Those Two Bad Guys: While he often initially appeared in the background of some scenes along with other Tough Customers, Season 5 onwards seems to be going forward with this route for him and Molly.
  • Took a Level in Kindness: Like Binky before him, he started off as a school bully in early seasons, then got hit with Character Development and Hidden Depths the longer the show ran. Prominent examples include helping D.W. with her ballet performance ("D.W., Dancing Queen") and coming up with good insults for her to use against the Tibble twins ("D.W., Queen of the Comeback"), befriending and teaching Brain and his friends how to play chess ("Brain's Chess Mess"), and putting up with Carl's autism without complaint ("Carl's Concerto").
  • Ungrateful Bastard: In S8's "Thanks a Lot, Binky", Rattles gets mad at Binky for "squealing" on him for trying to pull off a dangerous rollerblading stunt with his friends, even though said stunt would've broken every bone in his body and put him in the hospital for a very long time.
  • What the Hell, Hero?: He harshly calls out Arthur for lying to him and his friends in S1's "Arthur, World's Greatest Gleeper", making it a point to sit on Arthur and bounce a ball on Arthur's head as he did so.
  • Who Names Their Kid "Dude"?: Seriously, Rattles?

     Slink 
http://static.tvtropes.org/pmwiki/pub/images/edb8660b3a21a021394b7c4d1d2352c6.png
Voiced by: Michael Yarmush

A fourth grade rabbit with a tanner complexion than Molly, and another Tough Customer.
  • Ascended Extra: Initially a single-episode bully character from "Buster and the Daredevils", but is a recurring member of the Tough Customers by Season Six.
  • Blinding Bangs: Due to his hair. His bangs are even longer than Molly's, cover roughly half his face, and his eyes have only been seen once.
  • Dark is Evil: A bully and one of the only two kids to have a recurring black article of clothing (in his case, a black shirt with a red lightning bolt on the front).
  • Heterosexual Life-Partners: With Toby, at least until their efforts to humiliate Buster failed, and now they don't even attend the same school.
  • Meaningful Name: His moniker suggests that he may not be of the best repute. He isn't.
  • Series Continuity Error: When Slink was first introduced, he attended Mighty Mountain. He later appears at Lakewood Elementary with no explanation offered.
  • Who Names Their Kid "Dude"?: His name really takes the cake for this.
  • Wild Hair: The only elementary school boy to have longer hair.

Younger cast

    Dora Winifred "D.W." Read 
http://static.tvtropes.org/pmwiki/pub/images/dw_2549.png
Voiced by: Helena Mc Anham (Living Books, Arthur's Teacher Trouble game, Arthur's Birthday game), Michael Caloz (first three seasons), Oliver Graigner (seasons four to six, Arthur's Perfect Christmas), Jason Szwimmer (seasons 7 to ten, It's Only Rock And Roll), Robert Naylor (seasons 11 to 15), Jake Beale (seasons 16 to 17), Andrew Dayton (seasons 18 to 19), Christian Destefano (season 20 onwards)

Younger sister of Arthur and middle child of the Reads, and often the main character of episodes focusing on the younger cast.
  • Aesop Amnesia: She always comes back to create trouble for Arthur no matter how many times she sees the error of her ways.
    • In "More!" D.W. finally realizes how foolish she'd been to be chasing her friends and family for money....Only to be caught again asking Grandma Thora at the end of the episode.
  • All Girls Like Ponies: D.W. adores them. Her favorite idea for a holiday is Pony Day. Oh, and she loves unicorns too.
  • Annoying Younger Sibling: To annoyingly frustrating degrees.
  • Boyish Short Hair: Has a bob-cut. Her Traumatic Haircut in "DW Queen Of The Comeback" is even shorter.
  • Berserk Button:
    • Teasing her about her full name, anything involving her snowball, or saying that Unicorns and other fantasy creatures are not real.
    • In "DW The Picky Eater", being served spinach was a huge pet peeve of hers.
  • Blatant Lies: She's certainly not the most honest child. In "Go To Your Room, D.W.", when she gets sent to her room for being mean to Kate, she tells Nadine a bunch of falsified memories of how her parents abused her, like when they forced her to be Arthur's slave when he was sick and not allowing her to attend Aunt Lucy's wedding. Nadine doesn't buy a word of it.
  • Bratty Half-Pint: Whines when things don't go her way.
  • Call Back: Upon hearing of Kate's birth in "Arthur's Baby," D.W. does a cartwheel, a skill she worked hard to master in "D.W. Flips."
  • Chekhov's Gunman: After an entire episode of getting in the way, D.W. saves her aunt Lucy's wedding in "D.W. Thinks Big".
  • Companion Cube: Her snowball.
  • Chromatic Arrangement: In one episode, The Tibble twins do this to her clothes.
  • Deadpan Snarker: Has unfailing snark.
  • Does Not Like Spam: "I! HATE! SPINACH!!!" Cue Full-Name Ultimatum. She got over it, though.
  • Embarrassing First Name: Dora.
  • Embarrassing Middle Name: Winifred.
  • Full-Name Ultimatum: Heard often due to the amount of trouble she gets in.
  • Girls Love Stuffed Animals: She has a number of stuffed animals and sometimes carries them around, though this seems to show up more often in the books.
  • Go to Your Room!: A frequent punishment of hers. Usually the worst she gets.
  • Green-Eyed Monster:
    • D.W. was originally jealous of Kate, but saw how important her guidance as a big sister would be.
    • Season 20's "That's My Grandma!" sees D.W. getting jealous when Thora becomes the most popular babysitter in Elwood City.
    • A fair amount of episodes center on D.W. wanting something Emily has or has experienced, apparently not too fond of the idea of Emily upstaging her.
  • Here We Go Again: The final scene in "D.W. Flips" has her begging for horseback riding lessons, after she narrowly avoided both quitting and breaking her neck in gymnastics. She caught Arthur's Chicken Pox.
  • I Meant to Do That: D.W. tries to do a cartwheel, and lands on her back partway through.
    D.W.: I was doing a half - sault.
  • Idiotic Partner Confession: Usually something like, "Wow, Arthur. This person isn't as scary as you say." In "Arthur's Pet Business," she tells Mrs. Wood that Arthur lost Perky.
  • Informed Deformity: S10's "Operation, D.W.!" has her with hearing problems. First she doesn't hear her teacher call her and later she turns the volume up on the television way more than it should be. It's determined that she needs an operation to remove fluid in her ears. However, throughout the rest of the episode, everyone talks to her normally and she hears everything just fine.
  • Instant Expert: Usually at things that Arthur failed at.
  • Jerkass: She's such a big jerk that she even got punched by Arthur in one episode, which she deserved.
  • Jerk with a Heart of Gold: She's rude, bossy and is a right pain in the backside to Arthur, but a couple of times it is shown that she actually loves and cares about her brother deep down.
  • Karma Houdini: She's gotten away with her mischief many times.
  • Kick the Dog: "MOOOOOOM! Arthur broke a window!"
  • Little Miss Snarker: Usually towards Arthur.
  • Never My Fault: Usually passes off the blame to Arthur or her friends when she does something wrong and is rarely punished for her actions.
  • Only Known by Initials: Nobody calls D.W. "Dora" or "Dora Winifred" unless it's her parents issuing a Full-Name Ultimatum or they want to deal with a major tantrum. In S2's "D.W. Goes to Washington," Mr. Read actually didn't seem to remember her full name.
    Mr. Read: Her name is D.W.
    Secret Service member: That's it? Initials? You didn't give the kid a full name?
  • Only Known by Their Nickname: Never called by her full name unless she's in trouble.
  • Picky Eater: D.W. has a long list of foods which she does not like, most of which are Stock "Yuck!" vegetables. However, she did learn to like spinach after being served a restaurant dish in which it was the secret ingredient. The teaser for "Kung Fool" also shows that she unexpectedly loved a very green, very foreign dish her dad made, so we can safely assume she's ditched at least some pickiness.
  • Pink Means Feminine: Wears a pink dress.
  • Real Time: In "D.W. Gets Lost," Ed Crosswire asks for five minutes of Jane Read's time. This is how long she and D.W. are separated.
  • Security Blanket: She has one called "blankie" which was the focus of both the book and television story "D.W.'s Lost Blankie." One of the show's title cards depicts her wearing it as a superhero cape.
  • Small Name, Big Ego: She's quite the little braggart when she wants to be, usually at Arthur's expense. In "Play It Again, D.W." Arthur recalls the one time D.W. beat Arthur at checkers, and then proceeded to rub his face into it for apparently months afterward.
  • Tagalong Kid: Whenever she hangs out with Arthur's group.
  • Tomboy and Girly Girl: Tomboy to Emily's Girly Girl. Emily tends to have more refined manners and much less of a tendency to be bossy or take a leadership role. D.W. also seems like the hardier of the two girls when it comes to roughhousing/generally dealing with the Tibble twins.
    • In "Best Enemies," she is the Girly Girl to W.D.'s Tomboy. She loves unicorns while W.D. likes race cars.
  • Tomboy with a Girly Streak: She will climb trees, play catch with Arthur and Dad, and do other tomboyish (for her age) things. That being said, she is also very into unicorns, ponies, and anything pink.
  • Took a Level in Jerkass: DW becomes this in "DW's Very Bad Mood".
  • Traumatic Haircut: In "DW Queen Of The Comeback", her hairstylist cuts off a good chunk of her hair by accident, and DW gets teased by the Tibble twins for it.
  • Ungrateful Bastard: Has shown herself to be this many times.
    • In "D.W.'s Birthday Dilemma", after Arthur has spent an entire afternoon convincing D.W. that she has had a very good year and that she's got many more happy times coming, D.W. actually wishes for Arthur to end up with cake in his face, which is exactly what happens at the dinner table a short time later. The fact that it's Played for Laughs doesn't excuse her.
    • In another episode, D.W.'s parents spend the afternoon assembling a playset she has been wanting, but has so much more fun playing with the box that when it's ready for her, she doesn't want to try it out. Her parents call her out on her lack of consideration, and when she still shows no enthusiasm, they walk off totally deflated.
    • In the episode "More!", D.W. is given her first allowance, and she spends the rest of the episode demanding more money when she fears the other kids in her class are getting more. She even gets sent to her room for it at least once when she's called out for being disrespectful.
  • Unwitting Instigator of Doom: In "My Club Rules," when Arthur and his friends are in the treehouse discussing ideas for their parade float, DW barges in, wanting to hang out with them. Arthur, desperate to get rid of her, lies and says it's a "meeting" of the "Parade Float Club." DW immediately says she wants to "join." They have DW undergo "initiation rituals," such as kicking a bowling ball (which she refuses to do) and drawing a funny picture of Mr. Ratburn. They're so distracted from talking about the float that they're actually focused on making it a real club. A little while later, Muffy makes some snobby comments about how improvements can be made to Arthur's treehouse so it looks like a real clubhouse, and how club dues should be paid in order to implement the improvements. This leads to a fight amongst Arthur and his friends, causing them to form their own separate "clubs." They make up a few days later, of course, but still. It could be argued that if DW wouldn't have barged in to begin with, the argument wouldn't have happened and they'd still be discussing float ideas.
  • Why Did It Have to Be Snakes?: Saw an octopus up close during a field trip to an aquarium. While recounting the trip to her family, however, she claimed to have punched it.

Voiced by: Vanessa Lengies (first seven seasons), Sally Taylor-Isherwood (season eight onwards)

D.W.'s best friend and major character in D.W.-centric episodes. She is unique among the show's characters as she is part rabbit, and part ape.
  • A Day in the Limelight: "Emily Swallows a Horse".
  • Adaptation Dye-Job: Prior to season 6 she had shorter hair. In the books she had her current length but it was the same color as her fur.
  • Bratty Half-Pint: Almost all of her appearances in S1's "D.W. Flips", where she continues to rubs into D.W.'s face how much of a novice D.W. is compared to her in gymnastics class. Later seasons avert this by depicting her as D.W.'s best friend.
  • Bunnies for Cuteness: Part rabbit and cute.
  • Call Back: Emily beats D.W. and James in a swim meet, in a nod to her initial antagonistic appearance.
  • Gender Equals Breed: Both Emily and her mother are rabbits, while Emily's father is an ape.
  • Gratuitous French: She tends to use random French words and phrases from time to time, thanks to the influence of her French nanny Marie-Helene.
  • Spoiled Sweet: She's spoiled with tons of possessions, a private nanny, a tutor, and fancy food. Yet she's generally one of the nicest and most polite kids in preschool.
  • Tomboy and Girly Girl: Girly Girl to D.W.'s Tomboy. Emily tends to have more refined manners and much less of a tendency to be bossy or take a leadership role. D.W. also seems like the hardier of the two girls when it comes to roughhousing/generally dealing with the Tibble twins.
  • Took a Level in Kindness: Is mean to D.W. for almost all of her first appearance in "D.W. Flips". Nowadays, they're shown to be generally excellent friends.
  • Wise Beyond Their Years: Somewhat justified in that in addition to prekindergarten, she's also homeschooled by a tutor.

A shy boy in D.W.'s preschool class, and Molly's younger brother.

  • Morality Pet: Molly's sisterly love for him influences her character. When he also starts becoming a bully, Molly has a Heel Realization and tries to shape up for his sake.
  • Sibling Yin-Yang: A shy, kind boy who contrasts his sister Molly's tough customer act.
  • Took a Level in Jerkass: In S16's "The Last Tough Customer" he starts adopting Molly's bullying ways and rudely shoves a young girl just to get a drink of water. Molly realizes her bad influence on her brother and vows to shape up for both of their sakes.

     Bud Tucker Compson

Voiced by: Julie Lemieux

Ladonna's younger brother, and D.W.'s newest classmate. The only kid in preschool who can actually cope with the Tibble Twins.
  • A Day in the Limelight: "Bud's Knotty Problem" is Bud's first episode which doesn't give equal or greater attention to D.W.
  • Bunnies for Cuteness: A rabbit who is a cute preschooler.
  • Death Glare: Normally given to the Tibble twins.
  • Full-Name Ultimatum: Bud sometimes gets this from Ladonna.

  • Staring Contest: Bud is undefeated; he can beat all of his siblings and scare off the Tibble twins.
  • Tempting Fate: In the teaser for "Bud's Knotty Problem," Bud says that there is nothing that he and D.W. can't do together. It turns out that Bud can't tie shoelaces, and D.W. can't teach him how to do it.
  • Wanting Is Better Than Having: Bud's mom makes a deal with him, saying that she will buy him a new pair of boots with laces if he can learn how to tie them. Once Bud earns the boots, he tries them on and doesn't like them. Bud chooses a new pair of saddle shoes instead.

Voiced by: Carrie Finlay

Binky's baby sister. A bear cub, she was adopted from China in season 11. She mostly appears in Kate-related episodes.

Adult cast

     David and Jane Read 

The parents of Arthur, D.W., and Kate.
David is voiced by: Bruce Dinsmore (TV series), Tony Fardella (Living Books)
Jane is voiced by: Sonja Ball

  • Adults Are Useless: While they're a bit less lenient with D.W. than with Arthur, they do frequently let her get away with bad things that any other parent would have disapproved of.
  • Amazingly Embarrassing Parents: They have their moments of this, like whenever Jane buys clothes for Arthur or when David insists on telling bad jokes at Parents' Night in "Kids Are From Earth, Parents Are From Pluto".
  • Cloudcuckoolander: David is a downplayed example; In "Arthur Cleans Up" he is shown to easily get excited over things that he ropes Arthur in to that just leaves him feeling awkward or unsure of what he's supposed to do.
  • Cordon Bleugh Chef: David likes to experiment with his cooking... with less than desired results. Arthur initially thought he was a Lethal Chef, but he's actually a Supreme Chef... when not experimenting.
  • Happily Married: In contrast to Buster's parents, who are divorced.
  • House Husband: Both of the Read parents work from home. While David has his catering business, most of the money comes from Jane, who's an accountant.
  • Keet: David can get very loud when he's excited or passionate about something.
  • Laughing at Your Own Jokes: Dave, usually because nobody else gets them, much to Arthur's chagrin.
  • Lethal Chef: Played with. While Arthur initially thought this, it turns out David is actually an amazing cook. It's when he's experimenting in his cooking that the meals turn out a bit questionable. Either way, David is certainly not as bad a chef as Grandma Thora.
  • Never a Self-Made Woman: Jane straddles both sides of this trope; she shares household responsibilities with David while earning a sizable portion of her family's income, working from their home computer as an accountant. It's possible that Jane earns more money than David does.
  • Parental Obliviousness: They never seem to realize what a horribly spoiled kid DW is.
  • She Cleans Up Nicely: One episode sees Jane going downtown to do office work for a couple of weeks, and she looks great in a blouse, suit pants, and a new hairstyle.
  • Supreme Chef: David runs a catering business and he can make amazing meals... as long as he isn't experimenting.
  • Women Are Wiser: In the event that one of the couple has a lapse in focus or an emotional breakdown, Jane is more likely than David to take the lead.
    Ed Crosswire: Members of the Soccer Parents Association, I have some good news and some bad news. Trevor has decided to quit coaching soccer.
    David: Yes! Hey, maybe we could even win a game this year!
    Jane: *Whispering* David, I think that's the bad news.

     Thora Read 
Voiced by: Joanna Noyes, Michael Caloz (as a child)

  • Cool Old Lady: She is very in tune with the times and gets along well with everyone in Arthur's gang.
  • Friend to All Living Things: Adopts an abandoned dog named Killer who has been in and out of the pound through many owners; Thora refuses to give up on her and Killer starts a new lease on life.
  • Heterosexual Life-Partners: With Sarah MacGrady.
  • Lethal Chef: Notoriously so; her grandchildren do everything in their power to avoid actually eating her meals. Even David would rather that the cooking isn't left to her.
  • O.O.C. Is Serious Business: If she actually tells you that she's disappointed in you, you know you've messed up.
  • Women Are Wiser: Usually the voice of reason whenever Arthur, D.W., or their friends have a problem they feel they can't solve on their own.

     Oliver Frensky 
Voiced by: Mark Camacho
The father of Francine and Catherine. Works as a garbage man.
  • Amazingly Embarrassing Parents: Francine imagines this in "My Dad, the Garbage Man", and she feels the need to apologize for Oliver's excessive enthusiasm in "Arthur Cleans Up".
  • Beware the Nice Ones: He's as nice as they come, but will waste no time in disciplining his daughters if he finds them doing something foolish or malicious.
  • First Name Ultimatum: When Oliver decides to test out a newly-recovered baseball-pitching machine inside the apartment, it hits the bathroom door, irritating his wife.
  • Fun Personified: He's always cracking jokes, coaching sports, or having fun with his daughters.
  • Good Parents: He's very loving and caring toward his daughters, but he won't hesitate to scold them if he needs to.
  • Nice Guy: Easily one of the nicest characters on the show.
  • One of the Kids: He certainly has his moments, like wanting to be the first person to ride the bike that he renovated for Francine.
  • Working Class People Are Morons: Averted. Though he is a blue collar worker, Oliver is a pretty smart and nice guy, though his daughters (especially Catherine) thought he should get a more "respectable" job.

     Bitzi Baxter 
Voiced by: Ellen David
The mother of Buster who is now divorced. Serves as the editor of the city newspaper.
  • Alliterative Name: Her first and last name begin with B.
  • The Alleged Car: Her car, the "Baxtermobile", is a defining example of this in later seasons. Despite her lofty position as the editor of the Elwood City Times, she has yet to seek out a newer one.
  • Amazingly Embarrassing Parents: Used to be one in earlier seasons, due to her protective nature. A good example of this is in "D.W. All Wet" where she actually had a messenger send Buster his bathing cap while he was at the beach with Arthur.
  • Amicably Divorced: With her ex-husband, Beau Baxter. Why they divorced has never been explained.
  • Beware the Nice Ones: Generally fun-loving and fair, but will not hesitate to discipline Buster if she catches him doing something foolish or dangerous.
  • Characterization Marches On: Initially portrayed as overly protective of Buster, but has since become more laid back and fun loving.
  • My Beloved Smother: She dotes on Buster a lot and was once overly obsessed with his personal well-being.
  • Neat Freak: A downplayed example, but Buster's sloppiness and poor manners usually justify it.
  • Nervous Wreck: Her defining character trait in the earlier seasons, where she often frets over everything Buster does for fear of him getting sick or hurt. In later seasons though, she seems to have gotten over the worst of it.
  • Secret Handshake: Shares one with Buster.

     Nigel Ratburn 
http://static.tvtropes.org/pmwiki/pub/images/f64349dc1a7c8e8f0de6a3d2e5a6f756.gif
Voiced by: Arthur Holden (TV series), David Kessler (Living Books)

The third grade teacher of the Arthur gang, and the primary adult character featured in the show. He is a rat, obviously.
  • Ambiguously Gay: He is single, thin and neat. With the exception of some earlier episodes, he speaks in a somewhat "sing-songy" way compared to other adult male characters. His hobby is performing puppet shows, and he owns and maintains quite a collection of marionettes.
  • A Day in the Limelight: "The Return of the King"; "The Rat Who Came to Dinner"; "Get Smart".
  • Breaking Bad News Gently: "Everyone sit down, please. Mrs. MacGrady is sick. She has cancer."
  • Cool Teacher: His students don't like to admit it, but his a nice guy who, while strict, is very concerned about his student's well being.
  • Everyone Went to School Together: S1's "Arthur's Almost Boring Day" showcases Grandma Thora's old home movies, revealing that David Read, Mr. Ratburn, and Mr. Haney all attended the same high school at the same time. S15's "The Butler Did... What?" also reveals Bailey and Mr. Ratburn were in the same high school class.
  • Evil Counterpart: The one time we get to meet his mentor from college, he's shown to be a far more sadistic, cold and cruel version of Ratburn. Mr. Ratburn likely designed his teaching style off of being as work-intensive as his while being far less harsh to his students.
  • Face Palm: When Muffy attributes the creation of the Dewey Decimal System to Thomas Edison.
  • Freudian Excuse: The one occasion we encounter his mentor, who taught him everything he knows, its clear that Mr. Ratburn had to constantly work hard throughout his life to please him. His love of giving out homework most likely stems from this.
  • Genius Sweet Tooth: S3's "Dad's Dessert Dilemma" reveals that he LOVES cake.
    Mr. Ratburn: I just wanted of the Spring reading list-OH! Are you having cake?!?
    • Would carry over in S4's "The Rat who Came to Dinner".
    D.W: There was no cake Arthur. Mr. Rathead was very disappointed.
  • Heterosexual Life-Partners: With Arthur's dad of all people.
  • Hidden Depths: Mr. Ratburn is often seen by the Arthur gang as a cruel teacher who has no life outside of making kids miserable. At the same time, he likes Spooky Poo, and he volunteers as a puppeteer for children's puppet shows. Oh and of course, he goes giddy over cake.
  • Speech Impediment: We find out in "Maria Speaks" that like Maria, he once suffered from a stutter in his youth.
  • I Was Told There Would Be Cake: S3's "Dad's Dessert Dilemma".
  • Keet: Similar to Buster he loves eating sweets and he's a little too enthusiastic about teaching his students about subjects.
  • Large Ham: He certainly has his moments of this.
  • Misunderstood Loner with a Heart of Gold: He doesn't have much of a social life and is feared and hated by his students for giving out homework, but he's actually a very nice and friendly guy.
  • Nice Guy: He pushes his students to be the best that they can be, and won't take any nonsense from them. Overall, he's a really good guy.
  • Not So Fast: When and if he does let students off the hook, he'll call for a tougher assignment to make up for it.
  • Not So Different: With Buster. Both love eating and cartoons. Not to mention if the high school video is any indication, he was also just like Buster as a teenager. When shown this particular video, Ratburn blushes and starts whistling innocently.
  • Oh, Crap!: In "Cents-less", he and his class go without spending money for a weekend. Unfortunately, he forgets to buy food before announcing the assignment. He puts on a puppet show to barter for some food.
  • Only Sane Employee: While he's strict, he's the only teacher at Lakewood Elementary School who actually teaches his students properly. The only other competent employees are the lunch lady and the janitor.
  • Reasonable Authority Figure: Despite the kids complaining about Ratburn being a Sadist Teacher, he's always looking out for their best interest and is usually the one to call out one of the kids if they're being OOC like Arthur in "So Funny I forgot to laugh".
  • Species Surname: Played straight. Guess what animal he actually is!
  • Stern Teacher: The kids complain about Ratburn being this. Also frequently subverted when they realize he's not that bad of a guy (just a little strict and a bit too obsessed with handing out assignments) and he's actually succeeding in teaching them things.
  • Trademark Favorite Food: As noted above, anything to do with cake.

     Herbert/Francis Haney 
http://static.tvtropes.org/pmwiki/pub/images/998836805c537d1360e9f59bc49fff55.png
Voiced by: Walter Massey

Mild-mannered, well-to-do, absent-minded bear principal of Lakewood Elementary School. Often involved in episodes taking place at the school, though he is also involved in community work.
  • Butt Monkey: The early seasons often had some form of bad luck or misfortune happening to him, usually in the form of things falling on him, from raw hamburgers, to baseballs, to a bucket of popcorn, to Binky Barnes. S1's "Arthur's Almost Boring Day" reveals that he had bad luck befall him even during his school days.
  • Beary Funny: His haplessness and goofy behavior gives him this.
  • Beary Friendly: Very polite.
  • Cloudcuckoolander: He's a pretty spacey guy.
  • Death Glare: He briefly gives Mr. Ratburn's class this when he hears them cheering ecstatically over their teacher getting sick, in a Dude, Not Funny! moment.
  • Everyone Went to School Together: Attended the same school as Mr. Read and Mr. Ratburn. Even back then, as shown in the old videos in S1's "Arthur's Almost Boring Day", he had bad luck.
  • "L" Is for "Dyslexia": Shortly after George finds out that he has Dyslexia, Mr. Haney is also revealed to have it. This gives them something to bond over.
  • Reasonable Authority Figure: Generally manages the school quite well and gets along well with all of the students and staff, and when the situation demands it will take the necessary action needed to keep things running smoothly.
  • Running Gag: As noted above, he was very accustomed to having things dropped on him or having all manners of bad luck cramp his day, usually followed by the kids uttering "Sorry, Sir". As of later seasons, he seems to have caught a break.

     Sarah MacGrady 
Voiced by: Bronwen Mantel

The cafeteria lady at Lakewood Elementary.

  • A Day in the Limelight: The Great MacGrady, where she is diagnosed with cancer and forced to take a leave of absence while she undergoes treatment. All the children do what they can to support her until she's well enough to return to work.
  • Cool Old Lady: She's very streetsmart and is well-liked by everybody at school.
  • Heterosexual Life-Partners: With Thora Read.
  • Supreme Chef: Played with; there are several episodes where the students are served questionable meals, but Mrs. MacGrady is generally shown to be an excellent cook.
  • Unwitting Instigator of Doom: In "Arthur Accused" she absentmindedly bakes quarters earned for a school charity into a batch of brownie mix, which lands Arthur in hot water as he was to make sure she got them. Buster eventually uncovers this mistake, and so she's much more careful as a result.
  • Women Are Wiser: She has plenty of old school philosophies that have helped the children to overcome the questions and problems they face.

     Edward Edsel "Ed" Crosswire 
http://static.tvtropes.org/pmwiki/pub/images/fab059418fd6305880a8431cd973dd20.png
Voiced by: A.J. Henderson

Used-car salesman who is Muffy's father and somehow independently wealthy.

  • A Day in the Limelight: Despite (and perhaps due to) hinging on the kind of lesson that never seems to stick for Muffy, with Ed elbowing his way in on Muffy's class project, "Muffy Takes the Wheel" arguably has more to do with his character development than hers.
  • Good Parents: While he spoils his daughter rotten, he clearly loves her deeply and is very worried about her happiness.
  • Honest Corporate Executive: He's always trying to find new ways to sell his products, but he never makes false promises.
  • Honest John's Dealership: Subverted. He's not into false advertising, but is very...assertive when it comes to selling cars.
  • Meaningful Name:
    • An Edsel was a type of car made by Ford known as a commercial failure, but one of the meanings of the name itself is "rich."
    • "Crosswire." As in hotwiring a car. It can also mean "crossed wires", as in Rich in Dollars, Poor in Sense. It fits for his whole family.
  • Non-Idle Rich: He's a used-car salesman and clearly takes his job seriously, despite the pampered princess life he gives his daughter.
  • Nouveau Riche
  • Repetitive Name: His first name is Edward and his middle name is Edsel.
  • Self-Made Man
  • Well-Intentioned Extremist: Once tried to convince both the parents and the library that scary books were bad for children when Muffy supposedly suffered nightmares from them, going so far as to push the library to pull such books from circulation. After actually sitting down to hear one of them read and realizing Muffy actually enjoyed them as well, he has a change of heart.
