The Journal of Captain Rockhopper is the journal in which Rockhopper used to write his stories to send back to Club Penguin. However, he has now decided to stop writing in it. On April 25, 2008 it was placed in the Book Room's Library, and it can be read at anytime. Each time Rockhopper traveled back to Club Penguin, it was updated. Later on, it featured pictures taken on a camera given to Rockhopper by Aunt Arctic. He now uses a Notice Board in his Captain's Quarters for his notices instead of writing them in his journal. You can now find a key in the back of his journal. It allows you to go inside the Captain's Quarters. This key also doubles as a pin once you get it.
