Fertile

This biome was suggested by Crazyguy15052. He randomly said in a Skype chat:

"'I thinkkkkkkk that you should make a new biome that is the fertile biome that you can grow any crop anywhere...'"

And so then MCE thought of having the top block be unstompable farmland.

Generations
Nothing special generates here, other than the unstompable farmland. Lakes can generate. No trees, flowers or grass generates.
