Jeff pondered for a bit. Since he couldn't decide what to become, he'd let the computer do it for him. He still didn't want things to be completely random, he didn't relish spending time as an insect or even a short-lived single celled organism. The only way he could see to do that was to limit to a single general type of animal, so he chose mammal. He left everything else random.
It wasn't until he hit "Execute" that he suddenly remembered that he'd forgotten to hit the time limit!
He reached out to try and cancel the command when his room vanished around him. He was suddenly standing, naked, in the middle of a field of cows.
"Oh shit," he muttered.
The transformation didn't take long from there. He looked down in time to see a small udder take the place of his penis, then his body lurched forward and he fell to his hands, which were already useless lumps. He tried to cry out, but all that came out was a high pitched bellow. He... She suddenly realized that she wasn't a cow, but a young calf. She wasn't newborn, but was very young. She instinctively walked to a nearby cow, and feeling a hunger, took one of her teats in her mouth and started to suckle.
As she drank, she wondered what was in store for her. How long was random for the Chornovac? The shortest time she remembered seeing was minutes, but the longest was years! She hadn't had a chance to see what to expect!
