Bighorn Tortoises

In the seventh episode Brennan describes the Bighorn Tortoises as dusty indigo tortoises with curling rams' horns, built to fade into camouflage SOE7·00:32:53. He says they are fast and that the crew must jump to catch them SOE7·00:32:53. When hunted they skitter out of the trash and under a building SOE7·00:33:24.

The Bighorn Tortoises are small, fast, camouflaged tortoises that the crew catch in a sack on Baustin, and Plug calls them "varmints" that are bad news if they get in your cereal SOE7·00:32:53 SOE7·00:58:01. In the bag they multiply, and Riva says there are already three times the number SOE7·01:30:33.

They get aboard the ship: during the Brigade Tiger chase, Brennan describes little Bighorn tortoises jumping off the canyon wall into it SOE9·01:36:13. In the next episode the crew speak of a population of them breeding in the ship, and the reactor vibrations keep them out of that area SOE10·00:01:57 SOE10·00:48:58. Later Aurora Nebbins is shown crunching on one happily SOE14·01:52:29.
