Donkeys are passive mobs that can be ridden. Since Update 1.6, Donkeys can be spawned with a Horse Spawn Egg and are tamable. In Survival, they can be found naturally in the Plains Biome along with their horse counter-parts. They are one of four different possible mounts in the game as of Update 1.6.2, the other three being Horses, Pigs, and Mules.
