Jeanie is a curly redheaded girl who is friends with Emily and Alexander. She wears a green shirt with a sailor's collar around her neck and her skirt is checkered in red and green and has pockets. Her father is a mechanic and she mentions to him that his grandfather is an inventor. Her father has been framed by one of the police guards not recognizing that the robber is pretending to be him. As she gets on the cable car that moves without control, while the mice Emily, Alexander and Ernestine retrieve a bag full of dollar bills, Jeanie tries to wake up the unconscious police officer and tells him that her father is innocent and he believes her just before the cable car crashes near the police station and falls apart.
