It's Halloween in Peanuts land. Charlie Brown is thrilled that at last he's been invited to a costume party. Snoopy's costume choice consists of the goggles and scarf of a World War I flying ace, who is ever in search of the elusive Red Baron. And Linus makes preparations for the arrival of The Great Pumpkin, whom he believes will rise from the pumpkin patch and deliver presents to all the good little boys and girls. At episode's end, Charlie Brown finds himself with a trick-or-treat bag full of rocks; Snoopy once more fails to bring the Red Baron to heel; and Linus spends the entire night in the pumpkin patch, waiting in vain for the arrival of the Great Pumpkin ("But just wait till next year!") The second of Lee Mendelson and Bill Melendez' animated Peanuts specials, the 30-minute It's the Great Pumpkin, Charlie Brown was first telecast October 27, 1966.
