Author Jeff Lenburg mentioned an aspect of the series wherein Dorothy has to learn to believe in herself.[4]
In the series, Dorothy uses the ruby slippers to return to Oz. She learns that the winged monkeys have already resurrected the Wicked Witch of the West, who has conquered the Emerald City. The Wizard is trapped with a spell involving a never-ending wind, and Dorothy has to rescue him.
Despite using the slippers to return to Oz, in the episodes, Dorothy isn't entirely sure how the slippers work. Glinda often tells Dorothy to only use the slippers as a last resort. In one episode, Dorothy clicks her heels 4 times, as if each click is more powerful than the last. Aside from the pilot, generally when the slippers are used, they don't always help in the best way.
