Edison, watch out cause Orion hinchy has ideas

I have thought of a revolutionary idea: virtual pets that aren't so virtual anymore. However, Before you say "cats and dogs, hello!", think about it this way. We all know matter can be put together and pulled apart, right? Well what if someone created a robot with artificial inteligence that actually made itself different by eating, therfor changing it's appearance by rearranging the molocules of the food it consumes. We would give a kid a smaller, more childish robot, and as the kid grows up, so does the robot!
