“
Salo had a skin with the texture and color of the skin of an Earthling tangerine. Salo had three light deer-like legs. His feet were of an extraordinarily interesting design, each being an inflatable sphere. By inflating these spheres to the size of German batballs, Salo could walk on water. By reducing them to the size of golf balls, Salo could bound over hard surfaces at high speeds. When he deflated the spheres entirely, his feet became suction cups. Salo could walk up walls. Salo had no arms. Salo had three eyes, and his eyes could perceive not only the so-called visible spectrum, but infrared and ultraviolet and X-rays as well. Salo was punctual—that is, he lived one moment at a time—and he liked to tell Rumfoord that he would rather see the wonderful colors at the far ends of the spectrum than either the past or the future. This was something of a weasel, since Salo had seen, living a moment at a time, far more of the past and far more of the Universe than Rumfoord had. He remembered more of what he had seen, too. Salo’s head was round and hung on gimbals.
