Walls

Cobblestone Walls are blocks added in Update 0.8.0. They are similar to Fences except they are made with Cobblestone.

Types
There are two types of walls-
 * Cobblestone
 * Mossy Cobblestone

Uses
Mobs and the player cannot jump over a wall, making them a useful safety item around Lava, dangerous falls, etc. It can also be used to keep away hostile mobs.

A wall can still be climbed if necessary by placing a block temporarily in front of the wall, or putting a Carpet above it.

Crafting

 * 6 Cobblestone/Mossy Cobblestone => 6 Cobblestone/Mossy Cobblestone Wall
