Okay, you guys. So I was chain fishing just now in the cave part of Victory Road, and I got up to a chain of about 20. Then, stupidly, I reeled in to soon. I was kinda discouraged, and kinda wanted to fish somewhere else.
So I surfed back to shire, started biking up to the pokecenter, and BAM. Shiny Gurrdurr.
Is this a complete coincidence? Or can you use chain fishing to catch pokemon on land?
