Wall

Cobblestone wall is a block designed for decorative purposes such as gardens and are an alternative to fences. There are 2 types: cobblestone walls and mossy cobblestone walls. They work very similarly to fences, as they are 1.5 blocks tall (1 block in 1.4.3) to mobs. Cobblestone walls are more efficient at fencing off mobs than a two-block high cobblestone wall, costing only half as many blocks, and being more space-efficient as well. The drawback, however, is that a skeleton might shoot over the wall or a creeper could explode if a player is standing near the wall.

Bugs

 * Using pick block on mossy cobblestone wall will give the player normal cobblestone wall.
 * Cobblestone walls don't join up with fences.

Trivia

 * Interestingly, mossy cobblestone walls name is based on the old name for moss stone and not the new one.
 * When a fence gate is placed between 2 cobblestone walls (of either type) it will stoop down slightly to match the height of the cobblestone wall.
 * If the fence gate is only placed next to only 1 (mossy) cobblestone wall, or vice versa, it will not lower.
 * When you stack 2 walls on top of each other, you will get a small crack through which you can shoot arrows.
 * Although the cobblestone wall only raises at corners and ends, it will raise to support a solid or non-solid block placed above it.
 * Cobblestone walls function the same way as fences, yet are placed in the building blocks tab of the Creative inventory instead of the decoration tab.
 * Mob heads are the same size in width as the posts on a cobblestone fence.
