Dirt Path

Grass paths are a decorative block in the Pocket Edition, which are also in the computer edition.

Obtaining
Grass paths can only be gathered in the inventory using commands. When mined (even with a Silk Touch tool), they drop dirt.

From grass
Grass paths can be created by any type of shovel on the side or top of a grass block that has air above it. The shovel will lose 1 durability.

Natural generation
In the Pocket Edition, grass paths are naturally generated in villages, where they are used as pathways.

Usage
Grass paths are primarily used for decoration. They are a similar color to grass blocks placed in a desert or savanna biome, however a notable difference is they are only $15/16^{th}$ of a block high.
