Minecraft wiki entry for Advancement_guide, associated text: Horses and donkeys are found in plains and savannas, llamas are found in savanna and mountain biomes, and mules are obtained from breeding a horse and a donkey. Horses and llamas are tamed differently than other tameable mobs. To tame a horse or a llama, keep using them with nothing in your hand. The first few times, they may buck you off, but eventually, they will let you stay on and hearts will appear. This means that you have tamed them successfully. For more information on taming horses, donkeys, mules, and llamas, see the pages "Horse#Taming", "Donkey#Taming", "Mule#Taming", and "Llama#Taming".
