The message in a bottle to locate this castaway was last visible 4 days ago on 8 September. It will be visible again in 5 days on 17 September. (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.
On the island, players can talk to Squick. They have a fear of approaching water due to The Harbinger patrolling the seas. They request to be taken back to Nishi. They claim to be a parent when mistaken for a child. Occasionally, Squick will ink leaving squano on the ground below where they were floating, which has the examine of "How messy." Squick will also say Ick! when they leave squano.
