Mrs Creecher teaches class 3C at Bash Street School. She knows every single school rule off by heart, and enforces every single one of them.
Dennis, Rubi, Pieface, JJ, Walter and Bertie are all students in her class. She can be a very strict teacher, and isn't afraid of sending naughty students to see the Headmaster. However, when she gets replaced with the Edubot 4000, her students do start to miss her.
She thinks that her thick glasses help her see every little thing that goes on in class. In reality, her eyesight is really really blurry, meaning that her students can get up to loads of mischief. This means she'll read things incorrectly, or even call students by the wrong names!
At Bash Street School, she works alongside Olive the Dinner Lady, Ralph the Caretaker, and the other teachers at school. Her yellow kilt and sporran go hand in hand with her Scottish accent. She might live somewhere in Beanotown, but her students think she just goes to sleep underneath her desk at the end of the day - we may never know!
