Mrs. Jewls is the teacher on the 30th floor of Wayside. When Mrs. Jewls walked in for the first time on the 30th floor, she thought the children were monkeys, and although for the most part she has gotten over it, occasionally re-using it, especially for Todd.
In the books, not much is revealed about what Mrs. Jewls looks like aside from having a very nice face. The cartoon gives her large eyes with three eyelashes in each eye. She has a somewhat large nose and a large mouth. She also has lots of curly pink hair. She wears a yellow neckband, as well as a green blouse with creme-colored sleeves. On her blouse, there are two pockets towards the bottom. She wears purple pants with even darker purple shoes.
Mrs. Jewls is supposedly a very nice teacher, as she likes to help out students with their troubles, and always ends up teaching them three things every day, though interruptions may lead to her having to send the assignment as homework instead. She unfairly punishes Todd, usually for talking, but has sent him home for other reasons, even when his helping was beneficial to the class. Despite this, Todd still believes she is a very nice teacher.
When rewarding students, she will often hand out either gold star stickers or Tootsie Roll Pops. However, when students are disruptive or behave poorly (though, often most of the students aside from Todd get away with talking), she will have them write their name on the board. If their bad behavior continues, she will write a checkmark next to their name. If they continue to act poorly, she will circle their name and send them home early on the Kindergarten Bus.
