Peter is a man found panning by the water to the west at the Museum Camp on Fossil Island. He will reward players who have completed sets of Fossil Island tasks, as listed on the nearby notice board.
Peter can be spoken with to toggle different types of unidentified fossil drops. These two toggleable settings can be individually set. Players can choose whether or not to receive rare fossils, and whether or not to receive all other types of unidentified fossil. These settings will not affect any other item drop rates, as the fossil drop will not be replaced by any other items.
