Harry loves gym class-except for climbing rope. He's just too afraid of heights. But then a special valentine that Song Lee made for Harry goes missing. Now Harry must climb the rope in order to prove who took the valentine. But will he be able to overcome his fear? Or will Harry's Valentine's Day end horribly?

Horrible Harry has always loved insects, especially digging in the dirt for them. And, recently, he's discovered a new favorite: earwigs! But when he tries to tell his friends about these critters, only Song Lee listens. So when Miss Mackle assigns groups in Room 3B to act out different fairy tales, Harry sees an opportunity to teach the class about his favorite bug. Will they think his play is hilarious...or horrible?

"Best friends Harry and Doug must find their teacher's missing diamond in time for the class talent show."--

Doug discovers that though being Harry's best friend in Miss Mackle's second grade class isn't always easy, as Harry likes to do horrible things, it is often a lot of fun.

Third grade isn't looking too good for Herbie Jones. Not only is he stuck being in Apples, the lowest reading group in class, but he has to get a birthday present for annoying Annabelle and be good for the entire field trip to the museum! How is Herbie ever going to make it through the year?

Horrible Harry says goodbye in the 30th anniversary finale of a beloved series! The last day of third grade is approaching fast, but a farewell to Room 3B isn't the only goodbye Doug has to say this year. Song Lee and Mary are busy preparing an end-of-year present for their favorite teacher, Mrs. Flaubert, but their excitement can't distract Doug from Harry's suspicious silence. When Harry finally admits that his family is moving to a whole other town, Doug can't believe his ears. How will he survive fourth grade without his best friend?! But Harry has a more pressing question: who's that moving in to the empty house across the street from him? And what could these new neighbors mean for their friendship?
