One time a knook became tired of his beautiful life and longed for something new to do. The knooks have more wonderful powers than any other immortal folk—except, perhaps, the fairies and ryls. So one would suppose that a knook who might gain anything he desired by a simple wish could not be otherwise than happy and contented. But such was not the case with Popopo, the knook we are speaking of. He had lived thousands of years, and had enjoyed all the wonders he could think of. Yet life had become as tedious to him now as it might be to one who was unable to gratify a single wish.
