With fists clenched, Harry promises to show her one of the real purple people. But his best friend, Doug, thinks Harry is heading for big trouble. A colorful funny adventure featuring Horrible Harry and the other students in Room 2B.

There, a big, hairy guy with a bulky bag full of heavy things guards them all day. What does he do to them, and what’s in his bag? Horrible Harry’s curiosity is growing. He is determined to see what happens in the Suspension Room - even if it means going there himself. But going to the Suspension Room means Harry has to get into trouble first. How much is he willing to risk?Filled with equal measures of suspense and fun, Horrible Harry and the Dungeon will soon have you laughing out loud. 

The Christmas Suprise (1993)

It's Christmastime, but Miss Mackle has fallen off her reading rocking chair and ended up in the hospital. No one feels much like celebrating. Horrible Harry also knows he needs to write an appology letter to a classmate, and to somehow makeup for some of the things he has done. Maybe Harry can think of a way to cheer up Miss Mackle and put the holiday spirit back in Room 2B. Is Harry really so horrible?

How much trouble could a second-grader cause? Plenty, if it's Horrible Harry. Whether he's making Song Lee scream by showing her his pet snake, or playing a dead fish in the Thanksgiving play, Horrible Harry's just not happy unless he's stirring up trouble. But when one of Harry's classmates tries to get even with him by pasting canary stickers on his chair, lunch box, and library book, a showdown can't be far off. Will Harry be able to reclaim his throne as the most horrible second grader, or will Sidney's stickers humble Horrible Harry?
