Why? Because I said so.

Considerations to be made, however, is whether Dirt Nifty blocks can be allowed to grow Grass, becoming Grass Nifty blocks. Behaviour of Dirt will be replicated as such:

• Grass may grow on it
• Grass Nifty blocks will become Dirt Nifty blocks when mined normally.
• Plants will not be able to be planted on these blocks, mostly due to small hitboxes making it an oddity, and how plants can be placed.
• If allowed, should Dirt Nifty Slabs not become Grass Nifty Slabs if it is the lower Half Slab (Config TBD)?
• Can Sheep eat Grass Nifty blocks (knowing Mojang, probably not)?
• No, I am likely not to consider adding Mycelium, Podzol, or Coarse Dirt Nifty Blocks. I will make Grass-growing behaviour a Config option, however.
