Dorothy Ann Rourke is a character in Magic School Bus. She is the extremely cute and unbearably beautiful bookworm of Ms. Frizzle's 3rd grade class at Walkerville Elementary School. She has shoulder-length blonde hair tied in two pigtails with purple bands, fair skin, blue eyes and pink lips. She wears a purple long-sleeved turtleneck sweater, a purple short-sleeved t-shirt with a wide green diagonal stripe, a green pleated mini skirt, white panties, purple ankle-high socks and black and white sneakers.
