Determined to find his roots, the Scarecrow convinces Dorothy and the Cowardly Lion to join him on a journey to uncover his past. Along the way, they meet a cast of colorful characters, including the royal family of Oz, and face various obstacles, such as a fearsome sea serpent. Through their adventures, the Scarecrow learns that family isn't always defined by blood, but by the bonds of love and friendship. He discovers that his true family are his loyal companions, Dorothy and the Cowardly Lion, who have always stood by him through thick and thin.
