Christmas Island is a hidden island in the Arc region of the Wushanko Isles. Travelling to the island requires finding a message in a bottle in the Spirit Realm of Aminishi. The bottle is located on the beach below where the Aminishi moai rested. Investigating the bottle rewards a treasure map.
The message in a bottle to locate this island is currently visible. (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.
While carrying the map in the inventory, players can talk to Quartermaster Gully and will be asked if they agree to travel to the uncharted isle.
On the island, players can talk to Manti Claws, brother of Shanty Claws, to receive one taijitu. There is also a procedurally-generated amount of bamboo trees and tortles on the island. An ornate tortle may also rarely spawn amongst the regular tortles.
- Christmas Island shares its name with an island in the Indian Ocean.
