Jeff's face stung as he slowly slid to the floor, unable to stop himself.
A strange voice sounded from the computer speakers. "No life threatening situation identified, invalid key sequence entered, starting Automated Recovery; Cronivac Helper." A short pause later a human sounding voice began talking, "Ahh, hello there! My name is Arch, but you can call me Archie. People get themselves into all sorts of predicaments and often a desperate last second bash on the keyboard is all that stands between them and complete destruction of their life and dignity. Let's take a look at the last command and see if we can't make things better, shall we?"
Jeff was barely hanging onto his humanity and there was nothing else for him to do in this corner of the room. Although the transformation was paused for now, the effort he exerted and his new body were making him really hungry. The lettuce pile was calling him back, and acting on instinct he slimed his way back to his food pile and began feeding happily.
Archie came back, "Ahh, you see, you changed someone you are related to and reality. Part of the reality change was to change your Father to be attracted to a slug woman, which made him a slug man. He was 75% slug and you through the miracle of genetics are a whopping 95% slug mentally... or would have been." The chroivac flashed a brilliant light as Jeff munched away.
Awareness came back into Jeff's eyes, as a beep signaled it had finished. Archie inquired, "Jefferey, do you wish for me to remove all effects of your previous commands? Saying yes will undo any effects to you and other people, and only you will be aware of what happened. Reality will revert as though you had not activated the Chronivac."
"Yes!" Jeff cried, mortified and disgusted by his own body.
Another flash and Jeff was back to normal, as well as his room, house, family, and world. Jeff examined himself joyfully.
