Fern is the only one in class to enter a poetry contest, which is to be judged by famous poet Jack Prelutsky. The others think poetry is uncool, and start making fun of her. Fern bets them if they cannot write and submit their own poems, they must join the poetry club for a year. In doing so, Fern's friends find writing poetry fun. When their favorite series of books is banned from the library by a parental organization who believe scary books are bad for children, Arthur and his friends get together a petition to get them back — all except Muffy that is, as it turns out her parents are the founders of the parental group. Everyone gets a surprise when the books' author arrives to defend her books, and she happens to be Muffy's father's former teacher.
