Minecraft wiki entry for Savanna, associated text: The Savanna Plateau is identical to the regular savanna, featuring acacia trees and tall grass, though villages and pillager outpost do not generate here.[1] This biome is found when a savanna generates on top of a plateau or beneath a stony mountain. Horses still spawn on the plateaus and this is the only savanna sub-biome where llamas spawn‌[JE only].
