I have got some animals, let's say mooshrooms, situated at more than 20000 blocks away from my home base. I would like to safely transport them to my home base (20000 blocks away), with some efficient way. What are some good ways to move animals for such a large distance?
Nether transport: Ghast fireball attacks and occasionally falling into lava
Plain overworld transport: Mobs at night causes distraction; The mooshrooms also ignores me and my wheat on hand sometimes
Also I am playing on a server so using commands is not a valid solution.
