Overview:Wilhelmina is so sick of everyone liking Dorothy that she decides to unleash the Three Mischievous Imps on Oz. The Imps make it look like Dorothy is pranking everyone and soon the people of Oz are fed up with Dorothy's antics and the Munchkins put Dorothy in a candy prison. Dorothy knows that the Imps are going to wake the Hip-po-gy-raf and she has to stop them. With a little help from Ozma, Dorothy escapes the cage and stops the Hip-po-gy-raf from terrorising the city.
