Dorothy Ann "D.A." Hudson

"According to my research... wait a minute, wait a minute, wait a minute, that's Dorothy Ann Rourke! Well, she's the only blonde girl in Ms. Frizzle's class. But... I think you can call her... DA. Isn't that dang cool? After all, I would've gotten a few blonde-haired girls and boys in my own village back there."

--Su Ji-Hoon, Operation: Invasion Der Zukünftigen Akademie

Background
Dorothy Ann is a very beautiful class bookworm, always looking for a fact in one of her many books. Her last name "Rourke" is never mentioned in the books or original television series involving The Magic School Bus, but it is mentioned in the sequel series of The Magic School Bus, The Magic School Bus Rides Again. She loves astronomy, and she has a telescope on the balcony outside of her bedroom. She gets a new, high-powered one for her ninth (9th) birthday in a The Magic School Bus episode, "Sees Stars." She also has an interest in physics. Despite her intelligence and beauty, Dorothy Ann tends to have an argumentative personality and has clashed with the others from time to time, most notably Wanda ("Takes A Dive"), Ralphie ("Plays Ball"), and Carlos ("Blows Its Top" and "Makes a Rainbow").

Appearance
Dorothy Ann wears a violet turtleneck sweater, a turquoise pleated skirt, purple ankle-length socks (white stockings in some books), white panties (turquoise in a The Magic School Bus episode, "Out of this World") and maroon and white sneakers (saddle shoes in some books). She also keeps her blonde hair up in pigtails with two red rubber hair bands.

Her signature colors are violet and blue.

In the new series, she has her hair in a high ponytail held with a violet hair tier, and she wears a pale purple shirt, a light violet blazer, blue trousers and orange ballet flats.

She retains her old signature colors.

In When the Cold Breeze Blows Away, he now wears a Marine Corps Combat Utility Uniform (MCCUU) with a violet-and-blue camouflage. He also wears a Modular Integrated Communications Helmet (MICH). Underneath the blouse, he has a light violet V-neck T-shirt.

Season One
Dorothy Ann is introduced with the rest of the class in a The Magic School Bus episode, "Gets Lost In Space," but her researching habits are not shown until another The Magic School Bus episode "For Lunch." Her first focus episode is "In the Haunted House" in which she's conducting the class as they perform her "Concerto for Invented Instrument." She's seen doing a chemistry experiment while the class bakes Ms. Frizzle a birthday cake in another The Magic School Bus episode, "Gets Ready, Set, Dough." Her last focus episode of the season is another The Magic School Bus episode, "Plays Ball." Excited to show off her new physics book, she's disappointed when the class only cares about the baseball game they were playing. She's even more disappointed when Ralphie leaves her book on the field, but they end up inside it, playing a friction-less baseball game.

Season Two
The season opens with a Dorothy Ann-focused episode of The Magic School Bus, "Blows Its Top." She and Carlos argue over discovering a new island until she loses her books to the ocean. Feeling lost and empty without them, she begs Ms. Frizzle to help her get them back, "Please, Ms. Frizzle! I'm nothing without my books! Me, books... books, me!" In a The Magic School Bus episode, "Butterfly and the Bog Beast," her mascot suggestion is a broccoli, and despite her choice to choose a mascot, she sides with the others against Phoebe's butterfly idea. She speaks on "behalf of the court" during Ms. Frizzle's trial in a The Magic School Bus episode, "In a Pickle," and she's embarrassed by Carlos' brother, Mikey, when he brings up a heat rash she once got in another The Magic School Bus episode, "Getting Energized." In another The Magic Schol Bus episode, "Out of This World," she discovers an asteroid bound for Earth, more specifically, Walkerville Elementary and she gets the class to help her destroy it.

Season Three
In a The Magic School Bus episode, "Show and Tells," Dorothy Ann and Arnold are representing Walkerville in the 10th (tenth) Annual International Show & Tell Competition, and after researching Arnold's rare pumice collection, she's upset that he opted to bring an artifact she knows nothing about. She fights with Carlos again in "Makes a Rainbow" over her book, (Carlos says it's purple while Dorothy says it's violet), and which is bad enough for Wanda to comment, "This could get ugly." She's made a rain-forest inspector with Tim as her assistant in "In the Rainforest" when they try to find out why Ms. Frizzle's cocoa tree didn't yield a good harvest.

Season Four
Mr. Ruhle puts Dorothy Ann in charge of taking care of his pet Rhode Island Red rooster, Giblets, in a The Magic School Bus episode, "Cracks a Yolk," but she loses him once his master is gone. She turns 9 (nine) in another The Magic School Bus episode, "Sees Stars," in which the class goes on a field trip before getting together for her small party to find her a star as a gift. As she was sick, she stayed home, but Liz is with her, eating cake and looking in her new telescope. She and Wanda butt heads in "Takes a Dive" when she wants to work as partners, but Wanda wants to go solo.

Relatives
Her parents both appear in a The Magic School Bus episode, "Going Batty," and her mother appears again in another The Magic School Bus episode, "Out of This World." She has a little sister named Evan, who is blonde like her and their mother. Her parents also appear in a flashback in another The Magic School Bus episode, "The Tales Glaciers Tell," where they are revealed to be wonderful story tellers, and they appear in present at the presentation at the end.
