Hi so i'm hoping some one can shed some light on why this has happened, but when I came back from searching for the end portal, I see these two llamas near my house and I have no clue why this is happened(I have the screenshots). Can some one help?
Those look like 1.14 trader llamas, which spawn with a wandering trader villager. He probably wandered off or died somehow. I didn't know 1)that leads could be attached to leaf blocks and 2)that mobs could leash other mobs (and then tether them to a block!), but perhaps they still can't and you're on a server where a friend found the llamas and thought to gift them to you.
