The Journal of Captain Rockhopper

The Journal of Captain Rockhopper was a documented version of Rockhopper's adventures while he was exploring the seas. It was placed in the Book Room's Library, where it could be read at any time. Each time Rockhopper returned to the island, the journal was updated with a new entry. Following Aunt Arctic's decision to give him a camera, photos (originally they looked like hand-drawn illustrations) were later added to the journal's pages.

Captain Quarter's Key
The Captain Quarter's Key was located at the back of the book for all players to obtain. It gave the player access to the Captain's Quarters and doubled as a pin for the player to wear.
