The Scarecrow of Oz

In the 9th book of the the Oz series by L. Frank Baum, Cap'n Bill and Trot journey to Oz and, with the help of the Scarecrow, the former ruler of Oz, overthrow the villainous King Krewl of Jinxland. Cap'n Bill and Trot had previously appeared in two other novels by Baum, The Sea Fairies and Sky Island. Based in part upon the 1914 silent film, His Majesty, the Scarecrow of Oz. This was allegedly L. Frank Baum's personal favourite Oz book.
