Working on a dragon project in Room 3B leads to a war between two good friends--Harry and Song Lee.

Horrible Harry sets out to discover who Miss Mackle is going to marry, and he takes some risky moves to be the first one to know.

Best-selling children's author Suzy Kline delights listeners of all ages with this fun addition to the acclaimed Horrible Harry series. The kids in Room 3B are in an uproar. That rascal Harry is at it again-and this time, he might have gone too far! It all starts when Harry comes to school with a mini-microscope that everyone wants to try. Harry agrees to put on a show with it at recess, but he wants to look at mushrooms on the other side of the school...

Nearly every kid in Room 3B is trying to get picked for the South School Safety Patrol Squad--especially Harry. Harry wants a star badge just like his grandpa's, so he works extra hard to be the perfect student: hanging up his jacket neatly, organizing the crayons in rainbow order, and--his favorite part--cleaning up sticky noodles off the floor after lunch. But Doug thinks someone is taking the power of Safety Patrol too far, maybe even using it...

Horrible Harry must defend his reputation as a detective by cracking the secret code of Mrs. Funderburke's lunch prizes.

Follows the school activities of second-graders, Harry and Doug, as they participate in a secret mission to celebrate "Charlotte's Web," learn how to make green slime, and put on a skit warning about the dangers of smoking.
