The boy lay awake for a while thinking over the day's adventures, but presently he fell sound asleep also, and so weary was he that nothing disturbed his slumber until he awakened next morning with a ray of sunshine in his eyes, which had crept into the room through the open window by King Rinkitink's bed.
Resolving to begin the search for his parents without any unnecessary delay, Inga at once got out of bed and began to dress himself, while Rinkitink, in the other bed, was still sleeping peacefully.

But when the boy had put on both his stockings and began looking for his shoes, he could find but one of them.

The left shoe, that containing the Pink Pearl, was missing.
Filled with anxiety at this discovery, Inga searched through the entire room, looking underneath the beds and divans and chairs and behind the draperies and in the corners and every other possible place a shoe might be.

He tried the door, and found it still bolted; so, with growing uneasiness, the boy was forced to admit that the precious shoe was not in the room.
With a throbbing heart he aroused his companion.
"King Rinkitink," said he, "do you know what has become of my left shoe ?" "Your shoe!" exclaimed the King, giving a wide yawn and rubbing his eyes to get the sleep out of them.

"Have you lost a shoe ?" "Yes," said Inga.
