If you are talking about the new one you have to get a hard hat or controtion hat and press the dance button in the cave in the mine then find pieces of a treasure and then it will say congratulations you have got a new pin and opened a new cave. Then go to the cave and you will see a sign for a 50 coin diving suit. Then go to the lake cave it is called the Hidden Lake.

You get a jackhammer in the cave mine hidden on your map!
