At first, digging through the earth with your fists might feel a bit aimless, but you'd be surprised at what you'll find. Gold and Banandium Gems can show up almost anywhere, and there's always a chance you'll stumble upon a Treasure Chest. These can contain anything from piles of gold to helpful supplies like Balloons or Apple Juice, and most importantly, treasure maps that reveal the location of a Fossil on your map.
