Hi, I want that you can help me. I started the hallow quest, and I'm stucked here in ghoul swamp. I was looking for the 10 blue pokeballs, and I only found 9, only 2 spirits, and I need the third to complete this step, and can go to next area. I was searching all the area, and I can't find anything here, lot of times. So, please, I need that you can help to resolve this. I'll be waiting for your answer.
