This was originally going to be added in the Minecraft biome vote 2018 except the taiga biome won the vote. But I think the ostrich deserves justice and should be added to Minecraft! Ostriches could be such good mobs to be added to the savanna biome because that biome is so empty! They could be ridden on and you could tame them with maybe some new bug mobs but I do not want to force any of my ideas if this petition gets enough recognition for the ostrich to be added to Minecraft.
