There is indeed a shovel, which you can buy at just about every store that sells general goods (as in, not weapons or armor [or beer

] ). Once you get that shovel, which only costs about 80-130 GP, you can assign it to the D pad, or just look it up in the item menu each time you want to use it. There isnt too much good stuff to be had by digging, but if you ever wanna get that flammable, furry guy's weapon of choice, you need to dig for it
