All I can find are these derp looking fish. Are they any good? Is this a bug? I had 200 in my inventory yesterday and I had to throw them away to catch cooler looking Pokémon. Any idea where I can find something better?

Go to a gym. Sit on a skateboard or trolley. Anything with wheels. Grease them up so there is as little friction as possible. Sit indian style, google how to do this if you missed it in school. Then throw something heavy preferably some kind of weighted ball and observe what happens to the wheeled device you are…
