Exclusive to: Shipwrecked.
The Yaarctopus can be found in one of the Coral Reefs that generally spawn in the Shallow Ocean Biome. He is found lying on a Coral Rock wearing an eyepatch, a small pirate hat, an earring on the side of his head, and a wooden pegleg on one of his tentacles. He is immune to any damage and cannot be attacked. He is the Shipwrecked equivalent to the Pig King.
The player may trade any Fishes, Trinkets, and certain Fish Crock Pot recipes with the Yaarctopus in exchange for an Octopus Chest anytime except when he sleeps (which happens in night or after giving an item). Attempting to give any other item than the aforementioned ones, to a woken up Yaarctopus will result in them shaking its head. After handing in one viable Item, the Yaarctopus will fall asleep for the rest of the remaining day and cannot again be traded with until he wakes up.
For each Fish given the chest will always contain one Dubloon in addition to one of Seaweed (38.46%), Seashell (23.08%), Coral (23.08%), Blubber (7.69%) or Shark Fin (7.69%). If it has not already been obtained and Woodlegs is not unlocked, there is also a chance that the chest will contain the Golden Key (10.00%).
( not unlocked)
For each Trinket the chest will only contain a certain number of Dubloons. Trinket values are as follows:
It is often useful to set up an easy supply of fish near the Yaarctopus, to allow for easy supplies of gold to make tools. Several Fish Farms, or a number of planted Mussel Beds with Mussel Sticks can supply a decent amount of fish. (Note: It would take 3 days of continuously trading single fish to earn enough Doubloons to convert into a single gold nugget so this tip is only for those who have nothing better to do.)
- His name is a portmanteau of "yaar" (a pirate's phrase) and "octopus".
- It may happen that a Coral spawns right on top of the Yaarctopus. This does not hinder the player to turn in fish but can affect the spawning of the Octopus Chest.
