The Doubtful Dromedary was traveling with his friend, the Comfortable Camel, when they got lost in a sandstorm and ended up in Oz near the Deadly Desert. There, they met Dorothy Gale, the Cowardly Lion and Sir Hokus of Pokes, who were on a journey to find the Scarecrow. Not caring where they went, the two animals joined Dorothy's party and accompanied them to the Silver Islands, and then back to Oz. (The Royal Book of Oz)
