Hoglin

Hoglins are breedable hostile mobs and the main source of food in the Nether.

Spawning
These mobs are found in herds of 3-4 / 1–2 in crimson forests and they may respawn over time. 5% spawn as babies.

Drops
$$, adult hoglins drop:
 * 2–4 ( if they die burning). The maximum amount is increased by 1 per level of Looting, for a maximum of 7 with Looting III.
 * 0–2 . The maximum amount is increased by 1 per level of Looting, for a maximum of 5 with Looting III.
 * if killed by a player or tamed wolf.

Baby hoglins will only drop XP.

$$, adult hoglins drop:
 * 1–3 ( if they die burning). The maximum amount is increased by 1 per level of Looting, for a maximum of 6 with Looting III.
 * if killed by a player or tamed wolf.

Behavior
Hoglins avoid warped fungus (including in a flower pot), nether portals and respawn anchors. They naturally sink in water and if underwater will eventually drown. Despite being nether mobs, they aren't immune to fire. Hoglins can be leashed despite the fact they are hostile mobs.

Attacking
Hoglins attack the player on sight. $$, when an adult hoglin attacks, it flings the player into the air. The player will still be flung even if they block the attack with a shield. Baby hoglins also attack, dealing less damage and not flinging the player. Hoglins also do not attack a player standing near a block that repels them, instead prioritizing running away from the block. Hoglins have high knockback resistance. Baby hoglins flee when harmed.

Hoglins are hostile to piglins if they attack first. However, they avoid piglins if outnumbered by them, within 32 blocks. They do not attack other mobs.

Baby hoglins
Hoglins can be bred using crimson fungi, so a baby hoglin spawns, giving 1-7 experience. The growth of a baby hoglin is accelerated a bit every time a crimson fungi is used. They cannot be bred while they are running away from warped fungi.

Baby piglins will "play" with baby hoglins, riding them. If there are more baby piglins than baby hoglins, the baby piglins occasionally jump on other baby piglins already riding a baby hoglin, with a maximum of 3 stacked on a single baby hoglin.

$$, only 10% of baby piglins mount baby hoglins. Also, baby hoglins follow the adult hoglins.

Zoglins
If a hoglin is spawned or moved to the Overworld, it will start shivering and then turn into a zoglin after 300 undefined. If a lead is attached to the hoglin, it will break when the hoglin converts.

During Development
These images were showcased at Minecon Live 2019 or afterwards, but before Hoglins were add in 20w06a.
