Mud Block

Mud Blocks are a very common block type that comprises the majority of the Jungle, Underground Jungle, and Glowing Mushroom biome. Mud Blocks may be covered by Jungle or Mushroom grass on any side, which can only grow and spread on mud, and can be planted with Jungle Grass Seeds and Mushroom Grass Seeds, respectively.
