"Perhaps," said Grg, "we have been found ready to be taught!"

Then Grg twitched as a plllnk bit him, just under the front left double-tentacle. He combed the light fur there, found the plllnk, and shredded it, casting the pieces round-about so that no two of them might combine to form another plllnk.

How wonderful it would be also if the God could tell them how to get rid of the itching, crawling, parasitic plllnk, whose bite, in sufficient numbers, was often fatal!...

They shrank back, fearful that the display might be a disapproving communication—yet they held their ground, knowing they had lived good lives and deserved no condemnation on any score they could imagine.

The God lowered, on its belching tongue of flame—the flame that seemed a tiny part, a sliver, of the Universal Eye that Watched.
