He had to escape from this shell, or it would kill him. He had to expel himself somehow from this impossibly constricting container. Digging his front claws and most of his legs into the sand, he heaved, twisted, stretched, pushed. He thought of himself as being pregnant with himself, struggling fiercely to deliver himself of himself.

Ah. The carapace suddenly began to split.

The crack was only a small one, high up near his shoulders—shoulders?—but the imprisoned substance of him surged swiftly toward it, widening and lengthening it, and in another moment the hard horny covering was cracked from end to end. Ah. Ah. That felt so good, that release from constraint! Yet McCulloch still had to free himself. Delicately he drew himself backward, withdrawing leg after leg from its covering in a precise, almost fussy way, as though he were pulling his arms from the sleeves of some incredibly ancient and frail garment.

Until he had his huge main claws free, though, he knew he could not extricate himself from the sundered shell. And freeing the claws took extreme care. The front limbs still were shrinking, and the limy joints of the shell seemed to be dissolving and softening, but nevertheless he had to pull each claw through a passage much narrower than itself. It was easy to see how a hasty move might break a limb off altogether.

He centered his attention on the task. It was a little like telling his wrists to make themselves small, so he could slide them out of handcuffs.

—Wrists? Handcuffs? What are those?

McCulloch paid no attention to that baffling inner voice. Easy, easy, there—ah—yes, there, like that! One claw was free. Then the other, slowly, carefully. Done. Both of them retracted. The rest was simple: some shrugging and wiggling, exhausting but not really challenging, and he succeeded in extending the breach in the carapace until he could crawl backward out of it. Then he lay on the sand beside it, weary, drained, naked, soft, terribly vulnerable. He wanted only to return to the sleep out of which he had emerged into this nightmare of shellsplitting.
