Java Edition:Zombie Horse
Zombie horses were added in 13w16a (1.6 snapshot) but have never been available in survival Minecraft, except in 3 April Fools' snapshots.
Obtaining
20w14∞ Dimension
Zombie horses spawn naturally in some random biomes in random dimensions in 20w14∞. They spawn as passive mobs, thus they can only spawn on top of grass blocks with adequate light level. Spawning only happens every 20 seconds if there are no more than 10 passive mobs loaded.
One known location is the biome "_generated:1913198024" in dimension "zz" around 381, -411. Another is biome "_generated:773938501" in dimension "q3" around 1357, -1126. These coordinates seem to be consistent throughout seeds.
The spawned horses are always wild and have a 20% chance of being a baby zombie horse. Baby zombie horses are a temporary discontinued feature but can also be put inside a boat to get an oversized mob in a boat after the baby grows up, which will prove it was a baby even after it has grown up.
22w13oneBlockAtATime Spawn Egg
In 22w13oneBlockAtATime, there is a 1/996710 (≈0.0001%) chance that an enderman will spawn holding a zombie horse spawn egg. If that enderman is killed, the spawn egg can be obtained and used to spawn zombie horses.
