Ms. Frizzle

The curious Home Room teacher for 6th grade students. Not much is known about Ms. Frizzle, her appearances are often short and her face is always obscured. What she wants from the students is a mystery.

Personality
A true scientist, Ms. Frizzle is a mystery to both students and audience. She walks the line between scarily whimsical and cold and calculating. Her goals are unknown but she does at least seem to want her students to learn. Ms. Frizzle is attracted to students who stand out in her class. Those that catch her attention go on to be favorites and get stuck in an seemingly unending loop for as long as she wants. No one knows how long the loop has been going on or if anyone has made it out. So it is safe to assume that she hasn't reached satisfactory conditions to end it entirely.

She appears to have a petty streak. Carlos mentions that she has trapped Ralphie specifically in the loop with no memories or idea of what's going on based on an incident that happened years ago. While no one knows the specifics, she takes malicious joy in killing and torturing Ralphie. He is often used for the worst and most painful examples during the field trip. Other students who irritate her, try to leave, or interfere with her experiment are given "detention".

Physical Description
Ms. Frizzle is a tall woman who's face and legs are always obscured by the top of the screen. The only parts of her that are visible to the audience are her torso and arms. Her feelings are mostly conveyed by hand movements and the tone of her voice to make up for the lack of facial expressions. Presumably she has red/ginger hair like she had in the original show but it has never been seen on screen. So far she is depicted as wearing her space dress when she makes her appearances.

Stephen
Ms. Frizzle has paid special attention to Stephen. His curiosity and tendency to get into situations has definitely caught her eye. It is unsure if her attention is all positive or not as Stephen has definitely come close to meeting the same fate as Troy and other misbehaving students. She seems to have high expectations of him, why? We may never know.

The Lizard
Ms. Frizzle's lizard is just as mysterious as she is. It is unknown whether or not if it's an extension of her or a separate entity that works with her; however, the are on the same side. The lizard works as Ms. Frizzle's spy and reports back to her when a student is acting out of line.
