Possible Dirt

''This doesn't exist in Minecraft; it's just fiction. It can appear in Mods though.''

Possible Dirt or Possible Grass Block is a block that was introduced in the Possible World. one borrowed from the dirt block for the bottom, and an edited dirt texture with grass on the top edge on all of the sides. When covered by snow the side texture is white. On natural maps, grass appears on topmost blocks of dirt with no fluids or opaque solid blocks above them.

In mining, grass blocks behave just like dirt and Grass Block - they drop dirt resources and are best dug with a shovel; however, they make a different sound when harvested and take slightly longer to dig up, they also look slightly different from underneath. This can be used to tell when the player is about to break the surface when tunneling upwards.
