"Maybe you didn't cover everything in the special abilities list," Miss Featherpenny suggested softly.
Andy glared at her again. "All right, Blahrog. Can you think of anything you can do that most other species can't?"
Blahrog looked at the floor and considered. "We can walk a long way without getting tired," he offered.
Andy sighed, and wrote "Endurance?" on his scratch pad. It was scarcely saleable. "Is there anything else? Anything you know how to make? Besides Throatduster."
"We make good shoes," Blahrog said hopefully. "The tourists used to buy lots of them."
"Hum," Andy cogitated. "Here we have something for which a market already exists. If we can expand the market and the production facilities...." He nailed Blahrog with a finger, in conscious imitation of Crumbly. "How many pairs of shoes can Felix II produce in a single season?"
"If the reserves were called in to the Cobbler's Guild, it would be almost half the manpower of the planet...." Blahrog paused, doing mental arithmetic. "Four and a half million pairs, more or less." He sounded as though he were surprised.
"That ought to do it," Andy said gleefully.
"But where will we find that many pairs of feet?" Blahrog asked.
"There are eight million times that many pairs of feet in the Federation," Andy said. "Leave the advertising to Planetary Promotions."
