Mrs. Green

Intro Mrs. Green is a character in the children's book "The Teacher from the Black Lagoon" by Mike Thaler. In Hubie's nightmare, she appears as a monstrous creature who exhibits bizarre and frightening behavior in the classroom. However, in reality, the real Mrs. Green is described as a perfectly nice teacher with human features and no monstrous qualities. It is unclear if she is related to Mr. Green, the gym teacher mentioned in the story.
