Go treasure hunting with a friend in Rockhopper's ship, the Migrator, when the pirate docks in Club Penguin. Go to the Captain's Quarters, located below deck, and click on a pile of buried treasure.
Work with a friend, taking turns clicking rows and columns, and uncover treasure such as coins, rubies, and even a few rare emeralds. The more you work together, the more coins you will earn. When you finish, the earnings are shared equally between you and your friend.
