Maybe they could engineer the pigs to have different tastes. Normal ones with normal coloring would still have that yummy "pig classic" taste we all love. New ones could taste like beef, fish, chicken, chocolate, strawberry etc, all easily identifiable by snout color coding.

Wasn't the jellyfish engineering to see if they'd glow int the dark?

I could see herds of these being trained, just as rescue dogs are today, to help in emergencies. They could stand in formation to divert highway traffic, could run out on the sides of runways when the lights go out etc.

They could even make fashionable pets, suitable for walking in dark areas like Central Park, where their unearthly glow would not only light the place but would scare the bejabbers out of any would-be attackers.

And just wait until the raver crowd finds out about them! They could invent new dance moves, waving their pigs in trippy designs.
