Soul Sand (also known as Slow Sand, Mud, Hell Mud or Nethermud) is a brown-grey dirt-type block, only naturally found in The Nether, usually near large bodies of lava in deposits similar to gravel deposits. This material has looks somewhat similar to a Dirt block, but it has some unique features. It slows the movement of any player or mob, and players sink slightly into the block while walking on it. It is only 7/8 the height of a normal block, so the player cannot walk from a block of soul sand to a slab without jumping. Its texture has faces on it similar to tortured souls.
