"That's not bad," Pid said.
Ger tried a few practice steps, copying the bumpy walk of the Man.
"But I'm afraid it won't work," Pid said.
"It's perfectly logical," Ger pointed out.
"I know. Therefore the other expeditions must have tried it. And none of them came back."
There was no arguing that. Ger flowed back into the shape of a log. "What, then?" he asked.
"Let me think," Pid said.
Another creature lurched past, on four legs instead of two. Pid recognized it as a Dog, a pet of Man. He watched it carefully.
The Dog ambled to the gate, head down, in no particular hurry. It walked through, unchallenged, and lay down in the grass.
"H'm," Pid said.
