Instructions
Pay Willy Builder 16,500 chocolate coins to build a Mine on your property once you are level 26 or higher. Build the Mine close to town or a Helper House to increase productivity.
Go to Arfur's Inn and hire at least one Diggerling to work in the Mine. Diggerlings can be hired for 2,420 chocolate coins each. Give the Diggerlings chocolate coins to improve their morale and make them dig more quickly.
Wait for a Diggerling to find a Dragonache egg. There is only one Dragonache egg to be found in your garden. Take the Dragonache egg and place it in water.
Go to Miss Petula's Paper Pets and purchase a Cluckles for 1,100 chocolate coins. Press "A" to direct the Cluckles to the Dragonache egg to hatch it. If hatched in water the egg will become a Blue Dragonache.
