As the first one ascended into shallower water, the shape of his body became clearer: round, and, in general, sort of projectile-like. Some part of Ty’s brain wanted to identify him as a fat man. And maybe he was fat, in the same way that an otter or a seal is: a thick layer of subcutaneous fat held in beneath taut, rather thick-looking skin. But in no way did he seem flabby or jiggly. His overall style of movement suggested heavy musculature hidden beneath that smooth jacket of, for lack of a better word, blubber. Basically naked, he did have a kind of web harness strapped around his torso, with a sufficient number of odds and ends attached to it to make it clear that he was a technological being. At first the Pingers had seemed black, but as they came out of the water it became clear that their skin was dark gray, and mottled with patches of lighter gray, shading toward blues and greens. Their bellies were of lighter hue than their backs, and the mottling tended to run up their sides.
