Stone Forest

Based on real life stone forests, Minecraft Stone Forest biomes could be flat-ish areas that can expand into mountains with muted green grass, and instead of a forest of trees, tall stone pillars and boulders are everywhere. Bamboo grows between and around them, with the occasional small bush or rare tree. This could be a great place for any new mobs like mountain goats, or already present llamas to spawn occasionally. This could be a great place to find bamboo, or an interesting place to build a house. Stone Forests could be uncommon, not as easily found as a simple forest or desert, and could even spawn near biomes like jungles or plains if implemented.
