Treasure Chest can be found on a Island, which is in the Ocean Biome. They are not buried or hidden. To open it, players have to repeatedly hit it until it is destroyed, after which you get a random item inside it. It has health like a mob, not a structure, so weapons are the most effective for opening it.
A treasure chest does not spawn on a island that already has a treasure chest, and there can only be a maximum of 2 treasure chests on a server. When a treasure chest is destroyed, another one spawns on a random island, after a short delay. There is only one spawn location for each island, and they can be blocked by a structure, to prevent spawns.
