Skeletal/Zombie Horse

The skeletal and zombie horses are hostile horses coming on the Alpha update 1.6. They cannot be ridden by the player, for they are hostile. The skeletal horse can only be ridden by a skeleton. The zombie horse can only be ridden by a zombie. They may be hostile, but have no way of attacking yet. They have yet to be added as well. They share the same spawn egg as the Donkey or Horse.

Skeletal Appearance
The skeleton horse is the first animal with holes in its body. It looks like a horse, only with the features of a wither, wither jockey, spider jockey, skeleton, and wither skeleton.

Zombie Appearance
If the zombie horse spawns in a snow biome, it will have white spots in between its greenish skin. If it spawns in any other area, it will be completely green.
