On the first day of a new school year Mrs. Green's imagination runs wild as she thinks of all the horrible things she's heard about her new class, including that they've sent their previous three teachers into early retirement.

When Mrs. Green announces that a new student from far away is joing their class, her students worry that he may be a giant chicken, a bionic turnip, a body snacker, or even from Mars.

The students in Mrs. Green's class are excited to hear they will be having a substitute teacher, but their plans for partying and having fun all day change when they see who the sub is and what he has planned for the day.

Mean Mrs. Green says that everyone has to invent something for the school science fair. But everyone would rather invent a way to get out of it! Hubie can't decide on what he's going to do. He thinks all the good inventions have been done already. And all of his friends have figured out what they are going to do. He tries to decide between cloning himself or building a laugh machine. After a bad dream about cloning, he decides to build a laugh machine....

The students have heard some pretty scary stories about the school library. Is the librarian really as bad as they say?
