From Minor Demons:
Now you can share in the joy of owning a fish without the stinky, slimy mess! PortaFish is the ideal pet for the person on the go who doesn't have time to care for a tank full of real guppies. Part goldfish, part pirahna, PortaFish swims, eats, poops and lots more, and if you're feeling particularly sick, you can even fry him up for dinner. And unlike boring goldfish, you can do all sorts of neat things like feed him human body parts or see what happens when he gets a dose of radioactive waste!
