Moss Stone (previously known as Mossy Cobblestone) is a block that was first introduced in Survival Test and remains in all later versions of the game. It looks like Cobblestone, but with moss growing on it. Like Cobblestone, on the upper left, there is an 'L' that points to the north and east. Their only use is for construction - often used in combination with normal Cobblestone for decoration purposes, such as to make buildings look older or to make Nether portals more eerie. As of 12w22a Moss Stone can be found naturally in Dungeons or in Jungle temples.
