Are there any special "hidden" Pokemon that the game will pass over unless you find them in a patch of grass? I don't know any examples but just curious. I'm huge on picking up Pokemon in each area and not leaving until I have all of them so this thing is amazing and I hope they keep it. So when I catch all Pokemon in an area it will say "all Pokemon caught" or something like that?
Edit: I literally just got the game and got to the part where there was a pokemon's tail shaking in the tall grass and you have to sneak up on it, do those show up in that app too?
