Celebrate Halloween with Arthur and friends, perfect for fans of the hit television show and new readers alike.

With all of his classmates in costumes, Arthur can't tell who's who at the school Halloween party, and he nearly faints when Buster passes around snack bowls of "eyeballs" and "brains!" But when Arthur's little sister wanders off into the scariest house on the street while trick-or-treating, he's got to find the courage to go in and save her. Will Arthur and D.W. make it out alive on the most frightful night of the year?
