The third part of the series is an adaptation of the third Oz book, "Ozma of Oz" (1907). It starts with Uncle Henry, Aunt Em, Dorothy and Toto sleeping peacefully in their Kansas beds, but as Dorothy's Magic Shoes start glowing, causing the Shoes to transport Dorothy back to Oz, leaving Toto & her Magic Shoes in Kansas. She arrives in the Land of Ev, where a trio of Wheelers rudely wakes her up and accuses her of being a witch. Dorothy escapes the Wheelers, and finds a little mechanical robot called Tik-Tok which she winds up. She learns that Tik-Tok was on a secret mission, given to him by Princess Langwidere, to free the prince of Ev, but he got himself into trouble with the Wheelers. Then, rather than he protecting Dorothy, Dorothy defends Tik-Tok from the Wheelers and accompanied by him goes off to meet Princess Langwidere.
