Little Fuzzy by H. Beam Piper — Read

Ben Rainsford went back to Beta Continent, and Gerd van Riebeek remained in Mallorysport. The constabulary at Post Fifteen had made steel chopper-diggers for their Fuzzies, and reported a gratifying abatement of the land-prawn nuisance. They also made a set of scaled-down carpenter tools, and their Fuzzies were building themselves a house out of scrap crates and boxes. A pair of Fuzzies showed up at Ben Rainsford's camp, and he adopted them, naming them Flora and Fauna.

Everybody had Fuzzies now, and Pappy Jack only had Baby. He was lying on the floor of the parlor, teaching Baby to tie knots in a piece of string. Gus Brannhard, who spent most of the day in the office in the Central Courts building which had been furnished to him as special prosecutor, was lolling in an armchair in red-and-blue pajamas, smoking a cigar, drinking coffee -- his whisky consumption was down to a couple of drinks a day -- and studying texts on two reading screens at once, making an occasional remark into a stenomemophone. Gerd was at the desk, spoiling notepaper in an effort to work something out by symbolic logic. Suddenly he crumpled a sheet and threw it across the room, cursing. Brannhard looked away from his screens.
