Robin smiled uneasily. Without firearms and modern weapons he could still be overpowered if enough of the Moonmen attacked him at once. He would have to think about his approach to the tribe before he got there. They reached the tunnel and made their way once more through its dark recesses to the jungle-bubble where he had encountered Korree. They passed through this without incident. The Glassie led the way to one of several cracks and tunnels at the far end. With Robin following and the monkey Cheeky perched on the huge pack, Korree entered this tunnel. As before, it was dark and narrow and seemed to wind ahead. Several times they stepped around breaks in the floor, or ducked under low passages where the ceiling had dipped. They walked on, Korree's bobbing headlight casting a pale-yellowish glow a few feet ahead. Robin was watching the floor carefully, straining his attention to keep his footing safe. His ears registered the echo of their motions and the changing pitch as the tunnel widened or receded, but he paid less and less attention to this. Suddenly he looked up. And saw not the one glow of Korree's light but a number of smaller ones around them, distant ones, bobbing slightly, one or two yellow, one small white one, and three verging on red. He started and stared but Korree had said nothing. Finally he reached out and tapped the Glassie and whispered, "What are those lights?" Korree said back in a normal tone, "Animals. White light is hunting eater. I watch it." "Here? In this tunnel?" asked Robin, startled. "Not in tunnel," said the Glassie. "In new bubble-place." Robin looked around. Sure enough he had not noticed the echo of their feet in the last few minutes. The floor had changed from rock to sandy dirt and he realized that he had lost some of the enclosed-air feeling. It was indeed a new bubble-cavern--but a lightless one! Now, as he looked carefully, he realized that there were many lights around. There were tiny ones bobbing on the ground that were probably Moonworms. The others were almost certainly those of various animals. He took his flashlight out, suddenly clicked it on, and swung it around. They were in an open area, sandy with sparse clumps of mushroomlike vegetation growing here and there. He caught the scurrying flash of several translucent animal bodies dodging out of sight from the unexpected light of his flash. And when the beam was off, he noticed the headlights returning, augmented in number. "There are many bubble-places without light?" asked Robin. "Many," said Korree. "Glassies not live there, but many animals hunt there."
