Treasure chests are recurring objects in The Legend of Zelda series, appearing in every title since A Link to the Past. Found in both the Overworld and in Dungeons, each Treasure Chest contains an item that will aid Link on his quest. Smaller Chests usually contain common items and collectibles such as Small Keys, Bombs, Arrows, and various amounts of Rupees. Larger Chests contain rarer, more important items, such as equipment, Big Keys, Pieces of Heart, and large sums of Rupees. Some Chests are locked or otherwise guarded; some will only appear after the completion of a Puzzle in the same room.
