On the first day of school, a young boy expects only the worst when he discovers that his new teacher is the "monstrous" Mrs. Green.

There is a new bus driver driving the school bus today. His name is T. Rex Fenderbender. Could the "T" stand for "Tyrannosaurus?"

With everyone excited about baseball tryouts, Hubie hopes that practice and a new mitten nicknamed Grabber will help him make the team.

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....

Hippo and his jungle friends worry about Friday the 13th, start a band, and enjoy a magic show.

There's a new gym teacher transferring over from the junior high, and Hubie is worried. The junior high students say he's big, mean, and blows his whistle a lot. Will Hubie really have to run a lap around the world to pass Mr. Green's class? Will he be able to lift Mr. Green's pickup truck and climb up a rope while it's on fire?
