0–2 Bone if the horse is a skeleton horse. 0–2 Rotten Flesh if the horse is an undead horse. 0–2 Leather (except for skeletal horses). Dark pegasus have a dark red coat and wings. Pegasus have a white coat with feathered wings and blue eyes. Unicorns have a white coat with a long horn protruding from their head, and a yellow white mane. However, they are purely aesthetic and do not cause fires or damage to mobs or players. Nightmares have a fiery-red animated coat, with embers particles that fly out of their coat, much like lava. Some fairy horses have wings that resemble butterfly wings. Fairy horses come with many colors and unique wing patterns, which vary depending on what dye was fed to them. Skeleton horses are only bones, although skeletal unicorns still retain their horn, and skeletal pegasus retain their wings. Undead horses or zombie horses, are green-skinned with greyish eyes, and have animated flesh for their coat. Ghost horses are transparent and green, or grey if the ghost horse is a flying ghost horse, with visible eye sockets. Zonkeys are similar to zorses, but have longer ears and make the same sounds as mules and donkeys. Zorses have stripes and long ears, much like zebras, but have more of a greyish coat. Zebras have a distinctive black and white striped coat. Mules have a dark, reddish-brown coat and long, erect ears like that of donkeys. Horses in tiers 2-4 come with 1 of 9 unique coat markings: palomino snowflake, grulla overo/grullo, bay, dappled grey, bay tovero, palomino tovero, grulla/grullo tovero, black leopard, and black tovero.
They can have 1 of 5 base colors: white/light grey, buckskin, blood bay, mahogany/dark bay, and black. Horses do not change once they have been tamed, (unless they have been given an essence) though tamed horses may be differentiated by giving them equipment. Foals are much smaller than adults, and slowly get bigger as they age. Adult horses are approximately 1.4 blocks wide and long, and 1.6 blocks high. Horses come with many unique features and markings. The horse spawn egg will only spawn zebras and three out of four tier 2 horses. Mules, zorses, zonkeys, and horses that can only be obtained with essences or by breeding do not spawn naturally, and can only be spawned naturally by cross-breeding.
Zebras have a 10% chance to spawn in herds. Occasionally, babies will spawn in herds. Horses spawn on grass blocks at light levels of 9 or more with at least 2 block space above, usually in herds of 2–6.
