Sometimes. In some route (With some grasses) after I stopped walking for a while. Sometimes, I hear some Pokemon cries. Example: After 2 minutes I stopped walking in some route I hear some tailow's cry. But, I don't know what it means. please explain it to me!
If you hear the cry of a Pokemon in an area, it basically means you can find that Pokemon in the area you are in. It doesn't mean much more than that.
