Mob conversion is a game mechanic where under specific circumstances certain Minecraft:mobs can convert to mobs of a different type, or to a different variant of the same mob.

Data transfer

Template:Exclusive A mob which converts to another mob retains the following entity data, provided that the new mob utilizes said data:Template:Note

• AbsorptionAmount
• active_effects
• Age
• angry_at
• anger_end_time
• Brain.memories.minecraft:angry_at.ttlTemplate:Needs testing
• Brain.memories.minecraft:angry_at.valueTemplate:Needs testing
• CanBreakDoors
• CanPickUpLoot, except in the cases of zombie villager → villager and villager → witch<ref group="note">Villagers converted from zombie villagers always have this value set to Template:Cd, and witches converted from villagers always have it set to Template:Cd.</ref>
• CustomName
• CustomNameVisible
• data
• drop_chances, except in the cases of zombie villager → villager and villager → witch<ref group="note">In both cases, the tag is removed. This is presumably to prevent players from obtaining the main-hand item of a villager or witch created via conversion, which they would otherwise be able to do by following the steps below:
  

1. Zombify a naturally-spawned villager to obtain a zombie villager which can pick up loot
2. Hand the zombie villager a sword to set its Template:Cd value to Template:Cd
3. Cure the zombie villager
4. Get the villager to hold the desired item in its hand
5. Obtain the villager's held item by either:

 a. Killing it outright

 b. Converting it to a witch (which you can later kill to obtain its held item)

 c. Re-zombifying it and either killing the resulting zombie villager or handing it a sword again</ref>

Mobs which split into several upon death

• drop_chances
• equipment
• fall_distance
• FallFlying
• HurtTime
• leash
• Motion
• OnGround
