Shrub of Webs

The Shrub of Webs is a plant from the Witchery mod. These are trapped shrubs, and look identical to normal Dead Bushes. When an entity walks over this plant, it will explode into a mesh of Cobwebs around them. The Shrub of Webs can only be harvested by breaking the block it is on top of, which can only be dirt, grass, or sand. Though, due to an item ID problem within the mod it will drop a Rose of Webs, rather than a Shrub of Webs.
