A Diggerling is one of the Helpers that can be hired. He works in the Mine to dig up items like Gems. A Diggerling can be hired from Arfur's Inn for 2420 Chocolate Coins. The Diggerling is quintessential to obtaining a Dragonache. You must be at level 26 to purchase a diggerling. Once you buy him with the mine (16,500 coins), you can earn money and earn seeds, but you have to place the mine right. You can also use a Candary in the mine as long as it is wearing a gas mask (can be purchased at paper pets). Mine workings cannot be tinkered into gold.
