I got to thinking recently. When you get pigs, they find truffles for you by digging, right? If that's so, wouldn't it be great if you could occasionally find truffles by digging in artifact spots or hoeing on your farm? The truffle is always one of the last items I donate to the Community Center and I think it would be great if there was at least one other way to get truffles, albeit rarely for balance. It says on the wiki that the cart lady has a chance to sell truffles, but I have 504 hours of gameplay on record and I have never once seen her sell them!
