I was a professional chocobo digger in XI heehee. Even raised a green chocobo especially for it, and 5 mules to process everything I received.

Gathering is my favorite hobby in any game, but I especially liked chocobo digging. IX's debut version of it was also my favorite mini game in the series thus far.
I've read a few times that Yoshi stated that he has no current plans for this. That makes me a sad moogle.
I really hope its on the agenda for version 2.0 along with chocobo rearing.

The only iffy thing that I get stuck on is, what exactly would chocobos procure that isn't already available with the other gathering classes? The only thing that isn't covered currently is leather mats...which would be just...creepy.
