 Which words best describe the mob of creatures?
They were something more—and something less—they were, in short, humanity's hopes for survival! The blobs were a peculiarity of this planet about which nobody knew anything. They looked like overgrown fireballs, but seemed to have an almost sentient curiosity about anything moving on the ground. The two he'd drawn, Kaufman and Pinelli, seemed to be totally devoid of any sense of caution. The blobs hadn't seemed dangerous, and the local animals were apparently all herbivorous and harmless. They were ugly enough, looking like insects in spite of their internal skeletons, with anywhere from four to twelve legs each on their segmented bodies. There were three of the blobs dancing about over the grazing animals now, as they often seemed to do. Earth had ordered him to detour here, after leaving his load of deep-sleep stored colonists on Official World 71, to check on any sign of Hennessy. Now the three were streaking at fantastic speed to a spot near the ship, to hover excitedly above something that moved there. Under the dancing blobs, a horde of things was heading for the cadets. Shaggy heads, brute bodies vaguely man-like! One seemed to be almost eight feet tall, leading the others directly toward the spacesuited cadets. There was a momentary halt, and then the leader lifted one arm, as if motioning the others forward. One, at the front, was stuttering into life, and Gwayne dashed for it as the exit port slid back. Seen from here, the things looked horrible in a travesty of manhood. The creatures dived downward into lower ground, beginning to disappear into the mists. Then it cleared to show the mob of creatures doubling back on their own trail to confuse the pursuers. They'd have to get to the group with the cadets in a hurry or the horde would all vanish in the uneven ground, hidden by the fog. A blob dropped down, almost touching Gwayne. Gwayne jolted forward against the windshield, just as he made out the form of the eight-foot leader. The thing was standing directly ahead of him, a cadet on each shoulder. Another jeep had drawn up, and men were examining the cadets. The two were loaded onto a jeep while men helped Barker and Gwayne stow the bound monster on another before heading back. "I want that thing to live—and you're detailed to save it and revive it. I want to know what happened to Hennessy and why that ship was buried against detection.
