When Halloween came around I was playing with the Halloween Pumpkinhead mobs...here's what I came up with that one day. Sadly I never managed to spawn any glowing eyed spider jockeys are any cave spider jockeys.



After that made me remember the April Fools Day update 22w13oneBlockAtATime...

So far I've got barrelheads and pumpkinheads of all the villagers:




I put two villagers in each bin just in case I accidently killed one I had a backup. I started working on the humanoid hostile mobs, but they despawned quickly so far or took off their pumpkins or barrels as soon as I got back around to them.

The ones I've been able to get so far:
* Zombie Villager
* Zombie
* Zombie Piglin
* Stray
* Husk
* Drowned
* Skeleton
* Wither Skeleton
* Enderman (shocked this one worked)
* Evoker

I can't remember what else worked... I'm still testing the other mobs. I haven't been able to try the skeleton jockeys for the obvious reasons.

Edit:

Okay, there's a LOT more than I thought... just found out pigs work too. Chickens, bats and axolotls no... unless I'm doing it wrong.
