The Nome King was a little awkward, but when he was firmly astride the saddle he called in a loud voice: "Giddap!" When Bilbil paid no attention to the command and refused to stir, Kaliko kicked his heels viciously against the goat's body, and then Bilbil made a sudden start.

He ran swiftly across the great cavern, until he had almost reached the opposite wall, when he stopped so abruptly that King Kaliko sailed over his head and bumped against the jeweled wall.

He bumped so hard that the points of his crown were all mashed out of shape and his head was driven far into the diamond-studded band of the crown, so that it covered one eye and a part of his nose.

Perhaps this saved Kaliko's head from being cracked against the rock wall, but it was hard on the crown.
Bilbil was highly pleased at the success of his feat and Rinkitink laughed merrily at the Nome King's comical appearance; but Kaliko was muttering and growling as he picked himself up and struggled to pull the battered crown from his head, and it was evident that he was not in the least amused.

Indeed, Inga could see that the King was very angry, and the boy knew that the incident was likely to turn Kaliko against the entire party.
The Nome King sent Klik for another crown and ordered his workmen to repair the one that was damaged.
