Whatever these things are, they seem to lower the catch rate of a Pokemon by quite a bit. I tried looking it up, but I found nothing on either. Can anyone explain these?

Nobody knows what mystery terrain is. That's why it's called mystery terrain. Thick grass is explained here. https://www.dragonflycave.com/mechanics/gen-v-capturing It's also on Bulbapedia, but there it's called dark grass. https://bulbapedia.bulbagarden.net/wiki/Tall_grass
Huh. So being in double grass lower your chance of catching the Pokemon? I didn't know that. But how did someone know what the mystery terrain was in order to call it that and know that it lowers the catch rate?
