I was just playing my survival and a wandering trader appeared, I had no emeralds so I decided to kill him and take his llamas, but the llamas started to attack me, I putted them in a fence and ran away, so one llama attacked to the other llama and the llama that was being attacked died, but the other llama was spiting the ground, here is the reppresentation of what happened: https://youtu.be/-M7YlNd5ShA?t=120
