Mud bricks are dark-brown bricks only obtainable after traversing the way to the jungle.
The mud brick is made from the vastly abundant mud found in the jungle. If doing any form of building or terraforming in the jungle, these bricks serve as a good use of the new material.
Currently no structure spawns with this block or its variants.
These bricks are made with 4 jungle mud using a vanilla crafting table or your personal 2x2 grid, and are then craftable into slabs, stairs, and walls.
