Undead Mobs Are Immune to Freezing, Breaking Zombie Piglin Farms

Due to MCPE-236034, Zombie Piglins have a 0.75% chance to spawn as a special incorrect variant that is best handled by Powder Snow. However, because undead mobs are immune to the freezing status effect, this immunity prevents Powder Snow from working as the optimal way to handle this variant, breaking Zombie Piglin farms.

Steps to Reproduce:

1. Obtain or summon the special incorrect Zombie Piglin variant from MCPE-236034. /summon zombie_pigman ~ ~ ~ ~ ~ spawn_baby_jockey

2. Attempt to handle it using Powder Snow.

3. Observe whether the freezing status effect is applied to the Zombie Piglin.

Observed Results:

The Zombie Piglin is immune to the freezing status effect because it is an undead mob, so Powder Snow does not handle the special variant as expected. This breaks the best handling method in Zombie Piglin farms.

Expected Results:

The special incorrect Zombie Piglin variant should be affected by Powder Snow's freezing effect so it can be handled properly in Zombie Piglin farms, or the immunity interaction should be adjusted so this farm design remains functional.

Note1:

In Bedrock Edition, Zombie Piglins have a 0.75% chance to spawn as a special incorrect variant with several different behaviors:

• It is affected by Poison and takes damage over time.

• It is affected by Regeneration and regenerates health over time.

• It is not considered undead by other mobs:

  • It can damage the Wither, and the Wither will retaliate.

  • Nearby Armadillos do not roll up.

  • It is not actively attacked by Iron Golems, Snow Golems, Zoglins, or "Johnny" Vindicators; the aforementioned mobs (except Snow Golems) will still retaliate if damaged by it.

  • It is not rammed by Goats.

  • It does not cause nearby Pufferfish to inflate, and it does not take damage from Pufferfish.

  • It does not cause nearby Wandering Traders, Piglins, or Rabbits to flee.

  • It cannot ride Boats or Minecarts.

  • Smite does not deal extra damage to it, but the unique particle effect still appears.

Note2:

Players typically use Minecarts to gather Zombie Piglins together, and then use Powder Snow to freeze the incorrect jockey variant, which cannot move while riding the Minecart.
