Inga frees the enslaved people of Pingaree, who sail back home. Again possessing the pearls, he overpowers Cor who escapes and flees to Regos. Inga sees her and, recognizing her shoes, trades shoes with her. Zella, wearing the shoes but unaware of the power they convey, travels to the palace on Coregos to sell honey to Queen Cor. Queen Cor arrives on Regos and captures the now powerless Inga and Rinkitink, and brings them back to Coregos. The shoes are found by a poor charcoal burner, who takes them home to give to his daughter Zella. Inga and Rinkitink sleep in the palace, but the next morning both shoes along with the pink and blue pearls they contain are accidentally lost. The wicked King Gos of Regos and his army are easily defeated by the strength and invulnerability of Inga, and they flee to the neighboring island of Coregos, ruled by the equally wicked Queen Cor. Keeping the pearls secret from Rinkitink, he hides them in his shoes, and the three sail to Regos. Inga resolves to free his people with the aid of the magic pearls. All the people are carried into slavery, except Inga and Rinkitink who escape along with Bilbil.

One day invaders from Regos and Coregos arrive again, and seize King Kitticut before he can reach his magic pearls. Rinkitink usually rides Bilbil, a surly talking goat. The jovial fat King Rinkitink of Gilgad arrives in Pingaree on royal holiday, and remains as Kitticut's guest for several weeks. The blue pearl gives its bearer superhuman strength, the pink pearl protects him from any harm, and the white pearl speaks words of wisdom. Kitticut tells Inga that years earlier, when armies from the neighboring islands of Regos and Coregos attempted to invade and conquer Pingaree, they were repelled by Kitticut himself with the aid of three magic pearls. Prince Inga is the son of King Kitticut and Queen Garee, who rule the island kingdom of Pingaree.

The book was dedicated to the author's newborn grandson Robert Alison Baum, the first child of the author's second son Robert Stanton Baum. It is notable that most of the action takes place outside of Oz, and no character from Oz appears in the book until its climax this is due to Baum's having originally written most of the book as a fantasy novel unrelated to his Oz books over ten years earlier, in 1905. It was published on June 20, 1916, with full-color and black-and-white illustrations by artist John R. is the tenth book in the Land of Oz series written by L.
