She is a very strict teacher who doesn't tolerate anything and writes an "F" on people's foreheads with a red magic marker (black in Wakko's case) whenever someone doesn't follow the school rules or do something incorrect. In her first appearance, she is hired by Mr. Plotz to discipline and educate Yakko, Wakko and Dot. However, the Warners were able to deal with her. In the end, the Warners, disguised as Miss Flamiel, had her sealed in a crate and got Ralph, who thought the Warners were inside the crate, to lock her inside the water tower. Despite all that, Ms. Flamiel continued to be the Warners' teacher as shown in other cartoons, only this time she seems to be less strict and the Warners being more cooperative.
