Which was not completely inaccurate. The lower part of Robie's body was a metal hemisphere hemmed with sponge rubber and not quite touching the sidewalk. The upper was a metal box with black holes in it. The box could swivel and duck. A chromium-bright hoopskirt with a turret on top. "Reminds me too much of the Little Joe Paratanks," a legless veteran of the Persian War muttered, and rapidly rolled himself away on wheels rather like Robie's. His departure made it easier for some of those who knew about Robie to open a path in the crowd. Robie headed straight for the gap. The crowd whooped. Robie glided very slowly down the path, deftly jogging aside whenever he got too close to ankles in skylon or sockassins. The rubber buffer on his hoopskirt was merely an added safeguard. The boy who had called Robie a turtle jumped in the middle of the path and stood his ground, grinning foxily. Robie stopped two feet short of him. The turret ducked. The crowd got quiet. "Hello, youngster," Robie said in a voice that was smooth as that of a TV star, and was, in fact, a recording of one. The boy stopped smiling. "Hello," he whispered. "How old are you?" Robie asked. "Nine. No, eight." "That's nice," Robie observed. A metal arm shot down from his neck, stopped just short of the boy. The boy jerked back. "For you," Robie said. The boy gingerly took the red polly-lop from the neatly fashioned blunt metal claws, and began to unwrap it. "Nothing to say?" asked Robie. "Uh—thank you."
