Llamas spawn in small herds in mountain and Savanna biomes. They come in four different color variations, with two of the variations possible for each biome. They can be tamed like Horses, but cannot be controlled by players when they mount the llama. Once tamed, a Lead can be attached to the llama which allows it to follow a player. Up to ten other nearby llamas will also follow the llama wearing the lead, forming a "caravan".
Llamas can be equipped with Chests which will allow players to store their goods in a mobile container; however, the amount of storage space available is randomized, and it depends on the llama. They can also be equipped with carpets for decoration purposes.
If a Player or mob attacks a llama, the llama will spit on its attacker. Llamas will also automatically attack any untamed wolves that happen to stay too close. The wolf in question will fight back depending on the same data tag that controls the number of slots in a llama chest.
It should be noted that llamas are the only neutral mobs that can deal damage to players when they are in peaceful mode.
A trader llama is a tamed variant of a wild llama, which will appear along-side Wandering Traders after the release of update 1.14. These llamas Spawn in groups of 1 or 2, wearing decorations similar to what the wandering trader wears, and will be leashed to the wandering trader at its outpost. They will attack any nearby Illagers, Zombies (including zombie pigmen, and any other zombie variants), but will not attack Ravagers. If a player attacks their wandering trader owner, they will attack that player once.
