The Teacher from the Black Lagoon

In this hilariously engaging tale, a student experiences a vivid nightmare on his first day of school, where his teacher, Mrs. Green, transforms into a monstrous figure complete with a tail and smoke billowing from her nostrils. Upon waking, he's relieved to find that the real Mrs. Green is quite different, leading to a comically exaggerated portrayal of how rumors can shape perceptions of authority figures.
