Here is Rinkitink in Oz by L. Frank Baum, Book 10 of L. Frank Baum's immortal OZ series.
Meet Rinkitink--a kindhearted king who's as fat and jolly as old Saint Nick himself! When the jovial monarch sails for a visit to the island kingdom of Pingaree, he and his talking goat, Bilbil, are welcomed with open arms. Before long, Rinkitink's lighthearted ways and merry songs endear him to the king and queen of Pingaree, as well as to their son, Prince Inga.
But when the peaceful isle is invaded by fierce warriors, everyone from the rulers to the smallest child is taken off in chains. Only Prince Inga, Rinkitink, and Bilbil escape the conquerors. And so the three friends set out--aided by the magical Pearls of Pingaree--to rescue the prince's people.
Their perilous quest takes them across the vast Nonestic Ocean to the terrible islands of Regos and Coregos to the dark underground domains of the Nome King. Victories are followed by setbacks, which are in turn followed by strokes of good fortune. Just when it seems our friends have met their match in the clever Nome King, Dorothy and the Wizard of Oz arrive to lend a hand.
