Are you talking about to get the hidden room in the under ground mine? Well, you'd have to go to the puffle rescue game, be a member, and click the level with the black puffle. You pass the level, i belive, you get the key immediatly. Im not a member so im not sure how you get the key dead on, but i know that much. I'm Wowhoa or Wayss on CP. Hope i meet you some time!
