Grass is a block in the game CastleMiner. it is unlocked by getting the trial or full game. You can't use grass as a block in CastleMiner Z because it'll automatically turn into dirt upon picking it up or by mining it. In CastleMiner Z, enemies can tunnel through it. Upon mining Grass, players cannot replace it. In CastleMiner Z, Grass is the main surface block until about 800 distance, where the surface becomes sand thus leading to the Desert Biome.
- When the player creates a new world, the Spawn point (North Tower) is in the Grass biome.
