Kabumpo in Oz [Wizard of Oz #16]

During Prince Pompadore of Pumperdink's birthday celebration a magic scroll is found inside his birthday cake. It warns him that if he doesn't wed a "proper princess" within seven days, his entire kingdom will disappear. The prince, along with the old, wise elephant Kabumpo, the Elegant Elephant, set off on an adventure to the Emerald City to wed Ozma, princess of Oz.
