A devolved form of the pokemon magikarp. It does nothing other than sit there and be demoralizing and smells funny. You cannot kill or get rid of it. It doesn't matter if you catch it or not. It forces its way into your pokeball and throws the other pokemon out.
HOLY **** THAT POTATO KARP JUST KICKED OUT MY PSYDUCK!!!!!
