Moogles I had just taken as a general kind of life in Final Fantasy, and FF9 in particular. However, I was replaying it again, and remembered that there are two moogles found in Terra, who have apparently never been to or heard of Gaia or any moogles there. Are moogles originally from Gaia? Or is it like the land-bridge theory in America (Some crossed to Gaia when they could (the original assimilation attempt) and forgot their heritage). Could moogles be from Terra, and passed over with the other Terrian things like Oielvert and the Iifa Tree?

Or could I just be blowing all of this out of proportion and moogles just are there for final fantasy sake?
