Horrible Harry and his classmates all love Halloween. Everyone wears a costume to school-even Miss Mackle. Every Halloween Harry shocks his classmates with his scary costume. In kindergarten he was a bloody Count Dracula, in first grade he was the Loch Ness Monster, and in second grade he was a slithering snake. So everyone in Room 3B can't wait to see what Harry is going to be this year-and they're in for a really big surprise!
