Mrs. Bommley

Mrs. Boomley is Billy Forrester's new teacher in the film. She is portrayed by Andrea Martin.

When Mr. Burdock introduces Billy to the class, kids don't say hello to Billy when prompted and Mrs. Boomley asks them to say "Hello," which they do. When Billy writes his name on the board, the chalk breaks and the kids laugh, but Mrs. Boomley lowers her glasses to tell them to be quiet. She thanks Mr. Burdock and when he leaves, she tells Billy that the class is studying Ancient Egypt and when she pulls the map down, it goes back up and the kids laugh. She then shows Billy to his desk behind Erika, tells him next time to put his backpack in the cubby and welcomes him to his new school.

When the class is busy doing math, she notices gummy worms everywhere and hanging from Techno-Mouth and Plug and lowers her glasses at what is going on, and Billy continues his work.

In the classroom, Billy, Donny, Techno-Mouth and Twitch do research on worms and find a drawing that shows the "sphincter." One calls it a worm's butt and they repeat the word many times just as Mrs. Boomley steps into the room. The boys hide the website and get back to work on Ancient Egyptians.
