Horrible harry and his classmates all love Halloween. Everyone wears a costume to school-even Miss Mackle!

In kindergarten Harry 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!


頑皮哈利和他的同學都十分期待萬聖節到來，每個人都精心打扮來學校，就連麥蔻老師也穿上了應景服裝！

頑皮哈利還在唸幼稚園的時候，他打扮成吸血鬼德古拉，一年級時扮成尼斯湖水怪，到了二年級則是令人毛骨悚然的蛇，今年他的同學都迫不及待要看看頑皮哈利到底會以怎樣的裝扮登場，結果果然令眾人大吃一驚！
