The message in a bottle to locate this castaway was last visible 1 day ago on 18 March. It will be visible again in 5 days on 24 March. (wrong?) Once a message in a bottle is found and when a player has walked near its spawn location when it was visible it will always be visible, unless the message in the bottle or its treasure map is in the player's bank or inventory.
He is wearing the Cannonball! head override.
