The Illustrated Kabumpo in Oz [EPUB ebook] 

Prince Pompadore is celebrating his eighteenth birthday when out of his birthday cake bursts a magic scroll, a magic mirror, and a doorknob. The scroll warns the young prince that if he does not marry a “proper princess” in a week, his entire kingdom will disappear.
With the help of his elephant Kabumpo, Prince Pompadore sets out to Emerald City to find a princess to marry. However, the proper princess that the Prince is searching for may not be who he expects.
