Every Halloween Harry plays tricks on his classmates and dresses up as something scary or gross or both. He's been Count Dracula, a slimy snake and even the Loch Ness Monster. Everyone in Room 3B is waiting to see what Harry will be this year--and they're all in for a really big surprise! "There's laughs aplenty in the short snappy text--just the thing to turn new readers on to books."--Booklist for Horrible Harry and the Green Slime

The holiday season is here, and the kids in Room 3B are learning about all the different ways people celebrate. In addition to Christmas and Hanukkah, there's Kwanzaa, Three Kings Day, Korean New Year, and more. All the talk about holidays has everyone feeling festive. Everyone, that is, except Harry. He doesn't seem to care about the holidays, the class pet, or even the new student in class. It's clear that something is bugging Harry—but what could it be?

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?

Miss Mackle's class is learning about their ancestors, and everyone just found out that Ida's great-great grandmother sailed on the Titanic-and lived to tell about it.

Harry and his friends are so excited-it's going to be the perfect field trip. All aboard! Room 3B is setting sail! Illustrated by Frank Remkiewicz.
