The Octopus Chest (also called Octo Chest) is a special chest structure pulled from the sea by Yaarctopus after trading with him. It has 4 storage slots. After the player takes all the items inside, it will sink into the ocean. For details on contents of the Octopus Chests, see Yaarctopus Exchange Rates.
- The chest will not sink as long as it has any item inside. This can be used to the player's advantage when gathering items, especially Trinkets, with a Trawl Net. Before trawling, a cheap item can be put inside to prevent the chest from sinking. The player should then aim to finish trawling near Yaarctopus, so that any unused trinkets can be easily put in the chest for later trade.
- When spawned with a console it will be empty, as the Yaarctopus is responsible for spawning the items in it.
- Octopus Chest can be moved by Sealnado.
- The Octopus Chest used to have 9 storage slots.
