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 empties the chest from items, 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.
- Trading additional trinkets with Yaarctopus will not cause any already existing Octopus Chests to sink, allowing multiple chests to be spawned. This further benefits the player by allowing virtually unlimited free storage near Yaarctopus.
