- Agreed. This is probably right in canon.
- Bear in mind, this episode is working off of the false assumption that fossilization can happen to a bone left to rot. Fossils can only form if an organism is buried before it has a chance to rot completely. So it was probably a landslide or volcanic lahar that drove the Maiasaurs away from their nests when they were killed. Besides, a Troodon pack wouldn't be able to take out a whole herd. Like modern predators, they'd cut one animal out of the herd and take it down. It would be enough to feed the pack. Sorry, but there's no stable time loop here. At least, not one involving the Maiasaurs.
Since this portion is also animated, and the producer is often seen on the "sets" used in the episode, the series is live-action in this universe; it's obviously produced on a much higher budget than the series in our world. Presumably, the series there is about Ms. Frizzle's actual teaching methods, but it's Very Loosely Based on a True Story. This is why people always call in to complain about how unrealistic it is.
- Or the show is accurate, and the producer is keeping up The Masqurade.
- There is a woman who is "officially" recognized as Ms. Frizzle in Real Life, and she signs books. So, anything is possible.
- What about hurtling them to the edge of the solar system, back to the age of dinosaurs, and to the bottom of the ocean? Isn't all that slightly more scary than the bus talking?
- Nope. We prefer our transportation non-sentient, thank you very much...
- The show made it clear that the kids knew the bus was alive. Maybe it's mute. Or just prefers not to talk.
- On the other hand: It's from the Transformers universe. But it doesn't transform, for some reason.
- No, it does transform, it's just that the various transformations all retain a general bus-shape.

- The only problem with this is that the wheel was never invented in the Gurren Lagann-verse.
- WAHOO THE HELL DO YOU THINK WE ARE!!?!!?
The bus even turns into a yellow submarine a few times. Compare this image◊ with this one
◊.
- Oh, please. She's obviously a Time Lord, and the bus is her TARDIS (albeit a different model entirely to the Doctor's).
- Actually, there are bus TARDISes, as Iris Wildthyme note has one.
- The Doctor's Daughter after her first regeneration. She found a way inside the Time War and took a TARDIS. And Liz is her companion.
- Nah, she's obviously River Song in Cognito!
- I don't know why the TARDIS needs to be a different model, we know that sometimes River borrows the TARDIS without the Doctor knowing. She's probably just figured out how to hot-wire the Fragment Links and superseding the binary thingy to fix the Chameleon Circuit. She just re-breaks it after she's done so the Doctor doesn't suspect.
- The bus is her Stand Weird Science!
- Actually, we don't know Tim's last name either.
- At least we don't know if it's official. From what I hear, Jamal is his last name.
- "Jamal" is not Tim's last name. His last name was only revealed in a Rides Again tie-in book, to be "Wright".
- At least we don't know if it's official. From what I hear, Jamal is his last name.
- Jossed. The same Rides Again tie-in book that reveals Tim's last name reveals DA's last name to be "Hudson".
- Arnold:
- Phobias. Full stop. Something happened in his childhood that no-one in his family will talk about. As such, he has grown up with so many phobias/neurosis that he used to have trouble in "normal" society. He got a *little* bit better when he was able to channel some of his energy into geology and paleontology, but he still has trouble when he isn't focusing on those things. Ms. Frizzle's class is helping him get over that.
- Phoebe:
- Chronic shyness (except when she focuses on something), and an inferiority complex.
- Carlos:
- Possibly A.D.H.D. Possibly.
- D.A.:
- OCD that manifests with her need for knowing facts, and always having her book bag & books. She has to have them OR. ELSE.
- Ralphie:
- His love for comics/sci-fi/fantasy/etc. lead him to not focus in school/get his homework done/etc. He has no drive, and was flunking out (of second grade? Yeah- it's possible). So he was moved to the "special" school in the hopes that he wouldn't fail.
- Wanda:
- No self-control. She was too much of a problem for her "normal" teachers due to her lack of empathetic self-control, and her selfish bravado around other kids. As such, she was sent to the "Alternative" school.
- ...Or she just got into a fight, and caused problems.
- Tim:
- Mild form of Asperger's, manifests through his drawings... And the fact that he doesn't talk enough to *have* a personality. note
- Keesha:
- Keesha is/was a dancer based on her outfit.
◊ (Yeah, it's WMG time all the way). Either that, or she was a young beauty queen a la Jon Benet Ramsey. It gave her a complex, and she tried not eating... In 2nd grade. As soon as her parents realized what they had done to her, they pulled her from the dancing/modeling/pagenting route (and weren't jerkasses about it. However, a psychologist still recommended that she not be around the other students for... Some reason. (Keesha, like Tim, doesn't really seem *do* a lot, does she...?)
- Keesha is/was a dancer based on her outfit.
- Or alternately; they all have Asperger's, are high functioning. Nah nah I kid; although it honestly wouldn't surprise me if this was some kind of accelerated class.
- Also note that the bus has only four sets of windows, as in a short bus. *Progression of thoughts proceeds in head*...oh, God, what have I done?
- Leading to...
- Similar to above reasons for being a "special class," only its a special class specifically for children with pediatric schizophrenia or other some sort of brain damage. That's how they think that they have 'magical' adventures and transform into various animals and objects that they are learning about. Mrs. Frizzle only goes along with their own preconceptions, which explains why she's so calm...
- Agreed. Not only are they good at science, but they're all quite creative in different ways and "in the Haunted House" shows that they're all pretty decent musicians. The kind of brilliance that comes with Asperger's is much more over-specialized (even D.A.'s knowledge of science is too wide-ranging and multidisciplinary). Also, none of them (not even Wanda) have the kind of issues with empathy that you'd expect from someone with AS.
- Funny you should say that. As somebody with Asperger's I was much like D.A. where school was concerned. I did well no matter what the subject(music and art I did well for the class, not well as in "good at it"), especially at D.A.'s age in the show. College changed that a bit, though. If D.A. had Asperger's I see no reason why she could not do what she does in the show and try to know everything about everything.
- People with Asperger's do not have issues with empathy. That's a myth. Also, not all people with Asperger's are only brilliant at one thing. There are indeed plenty who are brilliant general.

- ...Woah... I want to read that fic. (Sort of. Maybe. I'm a little bit afraid of that, to be honest...)
- Here's the explanation:
- Arnold and Phoebe grew up and got married (sorry, Arnold/Wanda shippers, but this theory needs Phoebe). They have a daughter (let's call her Phoebe Jr.), and when she's born Ms Frizzle tells them that she's their daughter as an adult. She explains that Arnold and Phoebe would never have got together if they hadn't been baptized by fire (and forced to Take a Level in Badass) in fourth grade, and therefore Ms Frizzle is ultimately responsible for their relationship. She tells them that they all need to train their baby daughter so that she can go back in time and complete the Stable Time Loop. Ms Frizzle and Liz teach Phoebe Jr. how to use the bus, Tim, Carlos and Ralphie encourage her pun-tastic sense of humor and Ralphie teaches her to believe that anything is possible until it has been disproved. Tim helps her design her costumes, and Mikey teaches her to be a technical whiz. Wanda teaches her physical fitness and bravery, D.A. nurtures her intelligence and Phoebe teaches her to be kind and caring. Keesha teaches her skepticism to counterbalance Ralphie's influence, Arnold teaches her to be Crazy-Prepared and Janet teaches her to be arrogant/self-confident enough to endanger her eight-year old students every few days without any qualms. Eventually, when Phoebe Jr. is an adult, Ms. Frizzle reveals that Liz and the Bus are eternal heroes whose job it is to maintain the time loop, and that Liz developed a device that prevents its owner from aging. She hands this device over to Phoebe Jr., gets into the bus and returns to her own timeline to resume life as Phoebe Perlstein Jr. Liz then pilots the bus back to the present. This timeline's Phoebe Jr. gets into bus with Liz and travels to the point in time where Ms Frizzle first started working at Walkerville Elementary. She lives as Ms Frizzle up to the point where Arnold and Phoebe have a daughter, explains and then trains that baby to be her successor. She relinquishes the anti-aging device and returns to her family and friends, only seconds (from their perspective) after her departure.
- Not only that, but she came to the Magic School Bus Universe, and her TARDIS looks so cartoony because she's in a cartoon.
- The Bus is a TARDIS, Liz is her companion, and (for the sake of fandom tradition) Ms. Frizzle is an incarnation of The Rani.
- Romana, of course.
- River Song, post-Silence in the Library. Regaining her body also restored her ability to regenerate. And/or triggered a regeneration.
- Regeneration? Ms. Frizzle could easily be portrayed by Alex Kingston.
- She could even be the Doctor, regenerated as a woman.
- Well, I guess that means he finally got his wish to be ginger.
- Presumably she regenerates into Mary Poppins.
- No. She's Iris Wildthyme (From the expanded universe) who actually gets points for already having a bus (!) TARDIS.
- This might also explain why nobody ever calls her out on her habit of spontaneously going on dangerous field trips without permission slips or anything. She has some weird form of perception filter which causes the average person not to notice the school bus is alive, and when they are on their trips, there's some sort of filter on in the classroom, so nobody notices if they just dissapear.
- Much as I love this theory, don't Time Lords have two hearts? ...And in the episode on circulation, Ms. Frizzle was shown to have only one heart.
- Maybe she was Chameleon Arched.
- Fridge Brilliance: If Ms. Frizzle wanted to teach the kids about the human circulatory system, she wouldn't take them inside a Time Lord body.
- And it is canon that she has a Chameleon Arch. In the reptiles episode, she turns the class into reptiles with a device that dropped from the bus' ceiling. Why it wasn't painful is a Headscratcher to me.
- Perhaps the Doctor used an older Chameleon Arch, considering that his TARDIS is an older model. Maybe Ms. Frizzle is using an advanced Chameleon Arch model? One that is non-painful?
- Alternatively, how sure are we that that was really Ms. Frizzle's body?
- If she's River Song, we don't know how much of her is Time Lord and how much is human. I find it entirely plausible that she's River Song, and her particular kind of human/Time Lord hybrid only has one heart.
- Well, the First Doctor only had one heart, so perhaps it can be thought that Time Lords in their first incarnations don't have two of them yet. This might mean that if Miss Frizzle is a Time Lord, she hasn't gone through a regeneration yet.
- Maybe she was Chameleon Arched.
- Note that in the birthday cake book, it was specifically lampshaded that we never find out how old Ms. Frizzle is.
- Alternately, she IS Agatha. We already know that Agatha has messed with Time Travel.
- She has the "Calmly and almost sadistically sends innocent children into mortal peril" down pat.
1. Frizzle and Liz got in some trouble and used the Chameleon Arch to transfer her Time Lord identity. She now acts as a teacher to hide and unknowingly use the TARDIS to take this kids on adventures.
2. She is fully aware of what is going on. She decides to use her vast knowledge and become a teacher so that she can take kids on trips using her TARDIS's vast power. This explains why she's so eccentric and out there.
- Partially Jossed. River Song was recently revealed to be a Human-Time Lord hybrid caused by being conceived aboard a TARDIS in-flight.
And she steals stuff just to give children a covert geography lesson.
- Please. Everyone knows Carmen Sandiego is the Rani.
- Maybe the Rani is Carmen Sandiego AND Ms. Frizzle.
- Wait a second. "Cruisin' on down main street, you're relaxed and feelin' good. Next thing that you know you're seeing (WAAHAAHOO!) octopus in the neighborhood!". I'm not sure I understand.
- "Take a left at your intestine, take your second right past Mars." ...Ew...

- Or, the Planeteers could be their older siblings.
- It's very possible that Wanda is related to Gi. I mean, they look really similar.
- Or, the Planeteers could be their older siblings.

- Suburban Vancouver. They're shown to be close to both the ocean and high mountains. The portrait we see of the founder of the town in the background also looks like a Canadian Mountie. And though when they're in the lost and found in another episode we clearly see an American penny, and made a moment of it, doesn't necessarily mean that they're in America. Canadian coins get mixed in with change at least as far south as Rhode Island. And also, the show was produced in Canada using mostly Canadian voice actors. Chances are it's in Canada.
- Somewhere between Sacramento, CA, and Tacoma, WA. The vast majority of the evidence supports this, with only a few exceptions. Most of the wildlife they encounter/turn into is native (and in many cases, exclusive) to the west coast. They're also far enough north to experience four seasons. And it's stated directly that Walkerville is in America. The most likely location is Oregon or California, which have inland oil wells (seen in "Flexes Its Muscles"). The most defining characteristic of Walkerville is its fairly close proximity to the Sierra Nevadas ("All Dried Up"), near low to moderately high mountains that retain snow for much of the year (a characteristic of the Cascades; the climate of Oregon allows over half of Mt. Hood, about 11,000 ft. high, to remain snow-covered year round, whereas inland 11,000 ft. mountains barely retain patches of snow in shady crags during the summer).
- Alternatively, it could be right on the border between the U.S. and Canada. This would mean that, theoretically, whichever side it's on could easily be accessed by people from the other country. If the school is located on the American side, than theoretically some of the kids present could be Canadian and just live close to the border. Likewise, the same could be said if it's on the Canadian side. Another more extreme explanation might be that the town actually stretches right over the border, and the school is just located in the American part of the town.
- Except "Meets Molly Cule" and "Sees Stars" show Walkerville being somewhere on the upper east coast, possibly New England.
- How about in an American/English speaking enclave within Brazil? This small cutscene
from The Magic School Bus Explores the Solar System PC game shows the bus returning to the Earth. Notice something odd about where it lands?
- I think there's an episode or source of some kind that I can't fully remember where Walkerville is stated to be in Rhode Island.
- Too complicated to explain to children? Please. It's too complicated to explain to ANYONE.
You may believe that this is impossible, given that Susan is in her twenties in Thief of Time and hasn't left the Discworld at all, while D.A. is eight in The Magic School Bus. The solution, of course, is that A Wizard Did It. Literally. The faculty of the Unseen University in Ankh-Morpork realized that the Auditors of Reality were planning another attack on the Roundworld, so they convinced Susan to let Hex transport her there to head them off. Unfortunately, Ridcully stood on Ponder Stibbon's foot while Ponder was entering Hex's instructions, and the ensuing mess-up meant that Susan arrived on Earth/Roundworld having reverted to childhood and with no memory of her previous life. As Roundworld has no magic and doesn't run on Clap Your Hands If You Believe, Susan loses her powers, but obviously retains her personality, non-supernatural abilities and general badass tendencies. She also has residual subconscious memories and instincts which are the reason she's unfazed by the impossible field trips. If there's no magic on Earth, how does the bus work? Sufficiently advanced technology.
This explains D.A.'s prophetic dream at the start of "Out of this World": Susan often glimpses and/or dreams snatches of the future. In fact, Thief of Time implies that the Auditors tried to wipe out all life on the Disc by crashing a meteorite into it, so while wouldn't they try the same thing on Roundworld, given their notorious lack of imagination? This explains the entire "Out of this World" episode. Think about it, there were three other episodes set in space, one of which explained gravity and one of which was a tour of the solar system that explained about asteroids, meteorites and comets. The only new educational content in "Out of this World" is the so-called 'gravity slingshot' effect, which surely didn't warrant a field trip of its own. Note that "Out of this World" is the only episode where the field trip is not instigated by Ms Frizzle. Therefore this wasn't a plan of hers to educate the kids, but a genuinely necessary action.
On top of this, this theory explains why Insane Troll Logic always presses D.A.'s Berserk Button. It's also the reason for her Limited Wardrobe. Vestigal memories of being Susan (who always wore practical - sometimes severe - clothes in black, white and grey) influence her clothing choices, inspiring D.A. to wear severe roll necks and only wear two dull colours.
Elegant, huh?
- Arnold is in his teens and so agoraphobic that his mother decides to send him to a therapist. He resents this, so when the therapist asks him what triggered his agoraphobia he makes up a story about his traumatic year in fourth grade to screw with the shrink.
- The entire class (plus teacher) exist but there's no magic or weirdness. D.A. actually has low self-esteem (as implied when she loses her book bag in "Blows its Top") and the entire series is a dream caused by her subconscious trying to boost her self-confidence and make her confront her fear of failure and her feelings for Carlos. This would explain why she's the smartest and most consistently badass of the kids, and why she gets to save the planet in "Out of this World".
- Alternatively, the series is a prophetic dream D.A. is having on the night before she starts fourth grade. All the events depicted therein will happen, but haven't happened by the end of the final episode (when D.A. wakes up and goes to school). We know she can have prophetic dreams because she has one in "Out of this World".
- Phoebe is about to join Walkerville Elementary and is afraid that she won't fit in. The night before she is due to start, her subconscious makes her dream the entire series as a way of boosting her confidence.
- Why Bellatrix Lestrange? I think she's a Weasley.
- Except Arnold is canonically Jewish, so why would he believe in Purgatory?
- He converted?
- Considering that the mechanic that works on the bus also had aliens as customers, that's pretty likely.

- Alternatively, Walkerville is a future Termina. Ocean, Swamp, Mountain...probably canyons around there somewhere too.
- Alternatively, everything was just a dream that Dorothy Ann had when she fell asleep during a screening of Deep Impact.
Maybe when they were little, Valerie was that weird kid in class who got picked on a lot for her eccentricity before Carmen the mysterious Aloof Dark-Haired Girl came along, who couldn't stand seeing her like that (and their Apathetic Teacher wasn't helping). Early on they find that they share a love of learning about the world and all the wonderful things in it - again, with an Apathetic Teacher they may have been intellectually frustrated. Carmen tends to be more interested in anthropologic stuff in exotic places (e.g., cultural sites) while Valerie prefers to find out about nature and how something works, but there's plenty of overlap between the two (e.g., how could the Moai statues on Easter Island get to where they are now? Will you look at how majestic the Great Barrier Reef is!).
Their first adventures were of Carmen sneaking away and dragging Valerie along with her - this might expose Valerie to how interesting other people can be via cultural artifacts (if she's been picked on, she might have been adverse to social contact), while Valerie may act as a conscious for Carmen, who tends to disregard rules and might have turned out to be a straightforward villainess instead of the Gentlewoman Thief we know her as now. Through their worldwide travels (all hidden from the regular Powers That Be thanks to Carmen's legendary stealth abilities) they also form contacts with a wide variety of people who help them later in life - this is more obviously helpful for Valerie's backstory as the Magic School Bus episodes show her social network to be quite widely cast, but Carmen would also benefit from such a network as well in order to keep her activites on the down-low.
Their childhood experiences can help to inform their present career choices. For Valerie, she became a teacher to nurture nascent inquisitive minds - she knows how aggravating being bored at school can be thanks to her Apathetic Teacher. Going out with the bus to do really hands-on and up-close approaches to learning is about the most effective way to get kids to learn. For Carmen, perhaps at Valerie's encouragement that she can make the world a better place, she goes to work for ACME and uses her skills to become the best detective they've ever had, but the combination of bureaucratic rigidity (to which she's never been fond of rules anyway) and lack of challenge because she's so good drives her away from ACME and into founding V.I.L.E.
Whether they keep in contact today can go either way. If yes, then Carmen's status as the world's most wanted thief is going to keep their opportunities to stay in touch limited (though with a magic bus at her disposal, Valerie will still be able to, say, meet up for coffee in Paris on the weekend). If no, then it's possible Carmen's turn to crime was the breaking point where they fell out (and lots of drama ensued).
- The thing is, she's pretty obviously an elementary school teacher, and in most US school districts 6th grade is the first year of middle school.
- She also put her head in a miniature igloo and went in an ice crystal and seemed to be used to the temperature.

- Located in an American/English speaking enclave within Brazil or,
- Located in an alternate universe where Brazil was settled by English colonists.

- Actually, this theory has some practical value as well as being cool. First, it would minimize confusion for episodes with similar themes or plots to old ones. Classrooms change every year, with new students in place of old ones, new lessons to be taught. Secondly, it can allow the new show to make direct corrections to the old show while still having the old episodes happening in canon. Third, for subjects that haven't changed much, it helps to reduce redundant episodes as the viewer only sees what needs to be updated. Lastly, in modern days, it seems that the most likely way for kids to discover the Magic School Bus is through the tv show. If kids see an old episode right after a new one, and the kids have the same general traits hut different personalities, younger viewers might get confused. With new students come new personalities. Thus, I would recommend that the new show supplement the old one, rather than replace it Continuity Reboot style.
Maybe Doctor Who various aliens races like the Doctor's Galfrian race might come from planets which are million of light-years away from our own?.
- History: Time travel to various time periods
- English: Inkheart-style transport into books
- Music: Transporting themselves into music sheets and interacting with anthropomorphic music notes, a la that one scene from Blue's Big Musical
- Woodworking: Something that goes along the lines of Bob the Builder (the students use talking, sentient machinery) meets The Red Green Show (projects often devolve into a D.I.Y. Disaster)
- Math: Donald in Mathmagic Land-esque interaction with magical personifications of math things
Why do the books, by contrast, show a much larger class, most of whom are nameless or unfamiliar? Simple: the trial program shown in the TV series was a resounding success, so the next year, Ms. Frizzle is given a standard class size, and takes them on the adventures described in the books. (When students from the TV series seem to appear in the books, they're there as a kind of Early-Bird Cameo from the illustrator, who must have met them to get a better sense of Ms. Frizzle's teaching style.)
Oh, and her sister Fiona from The Magic School Bus Rides Again is actually the dreaded Cousin Janet!! She's also changed a lot since 4th grade, and changed her name and pretends they're sisters rather than cousins to avoid anyone figuring out the whole time-travel bit.
- You forgot to add that this theory would technically make Ms. Frizzle a MTF transgender woman.
- I didn't forget it, I implied it. That would obviously be the case and you're all such bright students.
- Ms. Frizzle being trans would also explain her love of pickles. The drug spironolactone, which some trans women take to reduce their testosterone, is a diuretic. Increased urination depletes sodium, and one popular solution is to eat a lot of pickles.
- Alex (the brown-haired student in the striped sweater) would be portrayed as Arnold's best friend and foil to his nervous tendencies.
- Amanda Jane (the blonde-haired girl in the green polka-dotted dress) would more or less be a female Arnold, but not as nervous as him.
- Carmen (the mix race girl in the red shirt) will serve as a smarter half to Carlos.
- Florrie (the Hispanic girl in the lavender dress) will act in a role similar to Keesha but will downplay her worrying tendencies.
- Gregory (The blonde-haired boy in the blue striped shirt) will act as a friendly bully with a soft spot for animals.
- John (the biracial boy in a blue and yellow striped shirt) will more or less serve as a younger foil to Carlos.
- Michael (the Asian American boy in the red and yellow sweater vest) will more or less be in the background.
- Molly (the African American girl in the sailor outfit and beaded bangs) will serve as the youngest of the students
- Phil (the redheaded boy in the green sweater) will be the oldest of the students, as well as the tallest.
- Rachael (the one that looks like a tomboyish version of Phoebe) will more or less be Wanda's best friend
- And finally, Shirley (the curly haired blonde girl in the flower pattern pink shirt) will be a Southern Belle with a slight crush on Arnold.
