It was not long, however, until Hun-Came and Vukub-Came, the princes of Xibalba, heard them at play, and decided to lure them to the Underworld as they had lured their fathers. Messengers were despatched to the house of Xmucane, who, filled with alarm, despatched a louse to carry the message to her grandsons. The louse, wishing to ensure greater speed to reach the brothers, consented to be swallowed by a toad, the toad by a serpent, and the serpent by the great bird Voc. The other animals duly liberated one another; but despite his utmost efforts, the toad could not get rid of the louse, who had played him a trick by lodging in his gums, and had not been swallowed at all. The message, however, was duly delivered, and the players returned home to take leave of their grandmother and mother. Before their departure they each planted a cane in the middle of the house, which was to acquaint those they left behind with their welfare, since it would wither if any fatal circumstance befel them. Pursuing the route their fathers had followed, they passed the river of blood and the river Papuhya. But they sent an animal called Xan as avant courier with orders to prick all the Xibalbans with a hair from Hun-Ahpu's leg, thus discovering those of the dwellers in the Underworld who were made of wood--those whom their fathers had unwittingly bowed to as men--and also learning the names of the others by their inquiries and explanations when pricked. Thus they did not salute the mannikins on their arrival at the Xibalban court, nor did they sit upon the red-hot stone. They even passed scatheless through the first ordeal of the House of Gloom. The Xibalbans were furious, and their wrath was by no means allayed when they found themselves beaten at the game of ball to which they had challenged the brothers. Then Hun-Came and Vukub-Came ordered the twins to bring them four bouquets of flowers, asking the guards of the royal gardens to watch most carefully, and committed Hun-Ahpu and Xbalanque to the "House of Lances"--the second ordeal--where the lancers were directed to kill them. The brothers, however, had at their beck and call a swarm of ants, which entered the royal gardens on the first errand, and they succeeded in bribing the lancers. The Xibalbans, white with fury, ordered that the owls, the guardians of the gardens, should have their lips split, and otherwise showed their anger at their third defeat. Then came the third ordeal in the "House of Cold." Here the heroes escaped death by freezing by being warmed with burning pine-cones. In the fourth and fifth ordeals they were equally lucky, for they passed a night each in the "House of Tigers" and the "House of Fire" without injury. But at the sixth ordeal misfortune overtook them in the "House of Bats." Hun-Ahpu's head being cut off by Camazotz, "Ruler of Bats," who suddenly appeared from above.
