A Mossy Cobblestone Wall is a decorative variant of the Cobblestone Wall, featuring a moss-covered texture that gives a more natural and aged look. It functions identically to other walls, connecting seamlessly with fences, walls, and solid blocks to create enclosures or decorative builds. Mossy Cobblestone Walls can be mined with any pickaxe; otherwise, they drop nothing.

They do not generate naturally and must be crafted using Cobblestone Walls and Vines or through stonecutting. Like other walls, they can be placed under a note block to produce a bass drum sound.
