Before the release of the heart of the sea there was an entry found in the buried treasure chest loot table named nautilus_core which was later revealed to be the heart of the sea. Despite the name change the heart of the sea continues to be referred to as the nautilus_core in most game files.^{[Bedrock Edition only]}
