This is a list of characters that appear in The Magic School Bus television series

Main characters[edit]

The school is located in Walkerville, USA (an American flag being present in city hall in "Gets Swamped") and is possibly located on the upper east coast ("Meets Molly Cule," "Sees Stars"). The original book series included additional students not seen in the TV adaptation.

Valerie Felicity Frizzle[edit]

Voiced by Lily Tomlin in the TV series and Tina Marie Goff in the games. Ms. Frizzle is a teacher at Walkerville Elementary. She is normally referred to as Ms. Frizzle, but her students sometimes call her "The Friz." While she is eccentric and a bit strange, The Friz is intelligent, kind, resourceful, happy, funny, supportive, loving and somewhat motherly. She loves making jokes revolving around the lesson she teaches, even if she is the only one laughing. A redhead, she wears wacky clothing that reflects the subject of each adventure and earrings that glow just before a field trip begins. She usually winks before the earrings glow (in the original books, her dress on the last page usually hinted at the plot of the next book; the very last book sees it covered with question marks.) She enjoys singing, seems unafraid of danger, and often refers to her relatives or ancestors during trips. She can make a lot of jokes like Carlos, and she also admires Carlos' jokes. She appears to be very attached to the bus, almost as if having a nostalgic connection to it. Her first name is revealed as "Valerie" in The Magic School Bus In the Time of the Dinosaurs.[1] Her middle name is Felicity. She also loves to surprise the students. To Arnold, she is strange.[2]


The class pet Jackson's Chameleon who goes on most of the field trips with Ms. Frizzle and the students, often getting herself into dangerous comedic situations. She appears to get jealous when the bus receives more attention than she does. In the episode "Gets Ants In Its Pants", she is visibly annoyed and disappointed when she does not get the recognition she deserves.

Liz is mute but often does things that one would not expect from a lizard in real life, such as driving the bus. In three of the computer games, Liz talks. When she goes to Herp Haven for a brief period her packing list includes: claw polish, scale moisturizer and fang paste. If Ms. Frizzle has to leave the students for a brief period for any reason, or if the class must split up, she leaves Liz in charge, acting as a sort of substitute teacher. In "In a Pickle", she is the supposed "Judge" in Ms. Frizzle's trial for stealing Keesha's 1st prize cucumber/turning it into a pickle (she wears the wig, and the outfit, and carries the gavel).

Liz does not speak on the show, however she speaks in the CD-ROMs although it appears that only the viewers can hear her. She is also seen at the end of most episodes with the producers of The Magic School Bus.

Arnold Matthew Perlstein[edit]

Voiced by Amos Crawley in a handful of episodes and Danny Tamberelli in the rest. Arnold is a bespectacled Jewish American boy. He is often seen as somewhat of a coward but is actually braver than he's given credit for (in "The Busasaurus," he scares off a T. Rex to save the class). Arnold also inspires the class with ideas and call him a genius. In the episode "Shows and Tells," he mentions that his great-aunt is the famous archaeologist Arizona Joan, a parody of Indiana Jones. In spite of his dislike of Ms. Frizzle's wacky field trips, he is on several occasions fiercely loyal to the teacher herself, as in "Lost in Space" where he defends her against his cousin Janet. Another example of this is in "In a Pickle" where he acts as a lawyer for Ms. Frizzle, taking his job almost too seriously. He has an intense interest in and knowledge of rocks and minerals and an extensive rock collection. Because of this, he becomes the only child to be a member of GRANITE, the Great Rock Admirers' National Institute of Tectonics Experts ("Goes Cellular"). In "Cracks a Yolk," he and Dorothy Ann share the only kiss on the series when she kisses him on the cheek. It is implied in the episodes "For Lunch" and "Holiday Special" that he has a crush on Wanda and vice versa, but in "Wet All Over," he has a crush on a girl in another class named Tiffany. It's also hinted in "The Busasaurus" that Phoebe has a crush on him as well. In "Goes to Seed" he mentions he's allergic to pepper and pollen. In some of the books and on the TV series, Arnold has orange hair, but he has blond hair in the computer games and other books. His middle name is mentioned in Ms. Frizzle's Adventures: Medieval Castle. In most episodes, he usually says "I should have stayed home today", or a variant of it. He has a bossy, rude, & know-it-all cousin named Janet.

Carlos Ramon[edit]

Voiced by Daniel DeSanto or Daniel Santos for short. Carlos is the Mexican-American class clown, always making a pun or joke about whatever situation the class is in. He is a hands-on learner, preferring to invent unique devices, such as an instrument or rain catcher, rather than learn from a book. Carlos tries to be funny by telling several jokes, but they often backfire and cause the kids to groan "CARLOS!" in an aggravated manner. By contrast, Ms. Frizzle seems to enjoy his jokes, sometimes even complimenting him on being observant in the process of making them up. In "The Magic School Bus Going Batty", his father also makes puns, to which the other kids' parents would respond, "Mr. Ramon!" also in unison. In the episode called "Gets Ready, Set, Dough," Carlos has the responsibility of making chocolate cake for Ms. Frizzle's birthday. In "Getting Energized" he entertains a crowd and can even do impressions of Arnold Schwarzenegger. In one of the producer segments one of the kids points out that Carlos's bad puns must come from the producers as heard in one of the phone calls.

Dorothy Ann ("D.A.")[edit]

Voiced by Tara Meyer. Dorothy Ann is the Australian-American class bookworm, always looking for a fact in one of her many books and is the brains of the class. She is usually called "D.A." by the others. She always carries her pink messenger bag, which holds her books. In the episode "Blows its Top," Dorothy Ann loses her books, but realizes she does not need them to learn about facts. She appears to love astronomy, especially in "Out of This World" and "Sees Stars", where she is shown to have a telescope. She appears to enjoy physics, as she is seen with a physics book in "Plays Ball." She usually wears her blond hair in pigtails tied in red hairbands, and in the episode "Goes On Air," she takes off her hair ties, her pigtails staying in place (as pointed out by Arnold). In the beginning of "Out of This World," she has a nightmare about an asteroid crashing into her school and in the climax, she is the captain of the ship and she has her own ideas to save our planet. Dorothy Ann's last name has never been mentioned in canon, the books or the TV show. It's also revealed that she has a little sister named Evan. She is one of three kids known to have siblings, the other two being Carlos and Wanda.

Keesha Franklin[edit]

Voiced by Erica Luttrell. Keesha is an African-American girl who is considered to be the most level-headed and realistic student in the class. She is usually the most sarcastic one as well. Because of her skepticism, she usually argues with Ralphie, who tends to live in his imagination. She is the only person to participate in every single field trip.

Phoebe Terese[edit]

Voiced by Maia Filar. Phoebe is the new student in Ms. Frizzle's class, and she's also an Irish-American girl who always referring to how things were at her old school (which is actually called "Phoebe's Old School," as seen in "Goes to Seed"). The caring soul of the class, she also seems to be a little bit shy, her biggest fear being revealed as stage fright in the episode "Gets Planted." Phoebe is an animal activist, as seen in "All Dried Up," "Cold Feet," "Spins a Web," "Goes Upstream," "Ups and Downs," and "Getting Energized." Her love of animals also includes bugs ("Butterfly and Bog Beast," "Spins a Web"). She has shown a poor ability in growing plants (not growing one herself in "Goes to Seed" and growing a pitiful bean plant in "Gets Planted"). Her father is blind as seen in "Going Batty," and like her, he makes references about her old school. In the episode "The Busasaurus", it is hinted she has a crush on Arnold by quoting "Gee, what a guy!" when he tries to save Dr. Skeledon's dinosaur egg from an Ornithomimus. Phoebe is usually paired up with Arnold the most out of all the other classmates in various situations. In the original books, her parents are never mentioned or seen, and it's implied she's being raised by her grandparents (The Magic School Bus In the Time of the Dinosaurs and The Magic School Bus and the Electric Field Trip)

Ralphie Tennelli[edit]

Voiced by Stuart Stone. Ralphie is the Italian-American class athlete. While in class, he likes to daydream. He is the only field trip student to wear a baseball cap. He plays a lot of sports, including soccer, basketball, hockey, and baseball. Ralphie is Italian-American, mentioning in the episode "Ups and Downs" that his mother's calzones "go down like rocks". He has a distaste for anchovies, which, as he tells the class in "Gets Eaten," his dad puts on pizza to keep him from eating it. He often serves as the leader of the students, despite a tendency to jump to wrong conclusions (as seen in "Goes Batty") and ignore better judgment (as seen in "In the City"). He is also occasionally rivals Carlos at jokes.


Voiced by Max Beckford in the first season and Andre Ottley-Lorant for the rest of the series. Tim is also African-American like Keesha, and he's the most observant and artistic student. He can usually be found documenting on what the class is doing (such as Liz posing on a crater on Mercury or his Ralphie-inspired comic book The Adventures of Weatherman or getting footage of the swamp for evidence to argue Carlos's case), either by drawing or filming. His grandfather owns a honey bee farm outside of Walkerville, and as a small job, Tim delivers the honey at the start of winter. Like Dorothy Ann, his last name is never mentioned in canon, the books or the TV show.

Wanda Li[edit]

Voiced by Lisa Yamanaka. Wanda is the boisterous Chinese-American tomboy of the class. Always willing to jump into adventure and going where "no kid has gone before," she serves as a foil to Arnold. She wants to solve all problems that face her. Despite her tough exterior, she loves ballet, especially The Nutcracker ("Holiday Special"). Wanda's favorite singer is Molly Cule (a play on the word molecule), and like Ralphie, she loves sports. Despite coming across as brash, she truly does care about her friends, such as in "Holiday Special," where she is disappointed that Arnold could not come along to see The Nutcracker due to his grandmother being ill. In some of the later books, her last name is Chen, as opposed to Li (which it is on the TV series), and she has an older brother named Henry, whereas on the TV series, she only has a younger brother, William.

Janet Perlstein[edit]

Voiced by Renessa Blitz. Janet is Arnold's know-it-all, rude & bossy cousin. She is very unpopular among the class, though she did manage to manipulate them into siding with her (and turning on Phoebe) when it came to naming the school mascot ("Butterfly and the Bog Beast"). Janet is so self-seeking that she usually tries to sabotage the class in some way to gain something for herself. She initially appeared in the book The Magic School Bus Lost in the Solar System, where it was stated she went to another school, but on the TV series, she attends a different class instead of a different school. Janet seems to be an only child, as Arnold mentions that she is his only cousin in "Butterfly and the Bog Beast."

She made eight appearances in the series & video games:

 The Magic School Bus 
  • "Gets Lost In Space"
  • "Butterfly and the Bog Beast"
  • "Gets a Bright Idea"
  • "Goes Upstream"
  • "Works Out"
  • "Gets Swamped"
  • "Sees Stars"
  • "Makes a Stink"

The Bus[edit]

The bus is "very unusual" and sometimes seems to have a mind of its own. It is capable of shrinking and expanding, as well as transforming itself into many kinds of items, most commonly as robotic animals in order to blend in with the environment in safari-type field trips. When it shrinks, so do its passengers, and occasionally, when the bus returns to its normal size when something was left behind, the other item is set back to normal too( "Gets Eaten"). It is usually completely under Ms. Frizzle's or Liz's control, although in certain episodes the bus exhibits independent, even irrational, behavior: in "The Magic School Gets Ready, Set, Dough," the bus malfunctions with size despite Ms. Frizzle trying to fix it, in "The Magic School Bus Holiday Special", the bus disassembles itself into raw materials (while scowling), after having done so to several other structures (though Wanda did angrily slam her fists in the bus's hood before it self-disassembled), and in "The Magic School Bus In The City", the bus after becoming a bear wanders off from the class into the city looking for food. Its abilities are due to unspecified, magical additions—the origins of which are never fully explained, although it would appear that the new components are subtle enough to avoid attracting much attention from outsiders as the bus is often seen undergoing inspection without anyone commenting on them—the Bus is capable of transforming into multiple objects, ranging from a speck of pollen to a time machine to a small planet. It is interesting to note that some of the bus' technologies also have specific names. For example, the device that allows the bus to shapeshift is called the "Mesmerglober", and the device that allows it to change size is called the "Shrinkerscope", (a portable version is called the Porta-shrinker). In some transformations, the bus itself comes in different colors. The dew-dinger is the device used to indicate whether the Shrinkerscope is wet, in which case it won't work. Some episodes have featured the class having to deal with problems in the Bus itself, such as a field trip to a bakery being jeopardised when the bus shrank unexpectedly, and another trip requiring the class to shrink down and travel through the bus itself after its engine was clogged by an inspector's peanut butter sandwich.
