Trivia

 * In Kingdom Hearts II, Atlantica is the only world without a single treasure chest.
 * Kingdom Hearts coded and Kingdom Hearts Re:coded are the only games in the whole series not to have a treasure chest feature due to the inclusion of the Bug Blocks.
 * In Kingdom Hearts Chain of Memories and Kingdom Hearts Re:Chain of Memories, treasure chests are only available using either Calm Bounty, Guarded Trove, False Bounty, or Room of Rewards cards.
 * There are no large treasure chests on Kingdom Hearts Chain of Memories, the large ones were later added in the remake for the Room of Rewards.
 * Also, there are only 13 large treasure chests on Kingdom Hearts Re:Chain of Memories since only one Room of Rewards are available in every floor.
