Horse

A Horse is a Passive Mob that was added in Update 0.15.0. They are tameable Mobs that naturally spawn in Plains and Savannah biomes.

Types
There are 5 types of Horses in Minecraft Pocket Edition.
 * Normal Horses can be tamed and ridden, and can be equipped with Horse Armor by opening their Inventory. The Inventory can be opened by opening the Player's Inventory.
 * Donkeys can be tamed and ridden, but cannot be equipped with Horse Armor. They can be given an Inventory by equipping them with a Chest.
 * Mules can be tamed and ridden, but only spawn when a Horse is bred with a Donkey. They behave similarly to Donkeys and can be equipped with a chest. The difference is that the Mule can share the speed and jumping characteristics of the parent Horse, unlike the Donkey.
 * Skeleton Horses cannot normally be tamed and ridden. They can be put into love mode but they will not breed. They can only be tamed and ridden if they are part of a Skeleton Trap.
 * Zombie Horses cannot be tamed or ridden at all.

Taming
To tame a Horse, the Player must tap on the Horse with an empty hand, or press the button. The Player will then mount the horse, while the Horse will "buck" to throw off the Player. Once the Horse stops bucking and hearts appear, the Horse will be tamed. Feeding a Horse increases the chances of it being tamed faster.

Riding
Once tamed, the Horse must be saddled. Then, the Player will be able to control and ride the Horse wherever and whenever they want to. When killed, Horses will drop the Saddle.

If riding through deep Water, the Player will automatically dismount. The Horse can be lured over the water using Food, or it can be lead using a Lead. The Player must try not to break the lead by swimming too fast for the Horse.

The Player can dismount the Horse by crouching/sneaking.

Horse Armor
Horses can be made to wear Horse Armor, which gives them armor points like the Player. Horse Armor can be found in Chests in Generated Structures like Villages, Dungeons, Desert Temples, etc. Leather Horse Armor is also Craft-able using Leather.

There are 4 types of horse armor in Minecraft Pocket Edition:
 * Version Exclusive: Leather Horse Armor
 * Iron Horse Armor
 * Gold Horse Armor
 * Diamond Horse Armor

Skeleton Traps
Skeleton Horses can spawn as traps which turn into a group of Skeleton Horse Jockeys when struck by Lightning. The trap only activates once the Player gets close enough to the Skeleton Horse. The Skeleton riders also have a Projectile Protection I-III Helmet which they drop when killed. The Skeleton Horse will be tamed once the rider is killed, allowing the Player to ride it, therefore making it the only way to ride a Skeleton Horse.

Trivia
