Bow mortals before the Horse(man) of Death!

So yea, I have an unkillable horse corpse on my lawn; not the best look for my delightful garden.

It was a pet horse with saddle, tied by a lead to a fencepost, that was attacked. I received the horse under attack alert and, in the interest of expediency, I went straight to bed hoping to burn the bastard zombie munching on my ride. Upon arriving, a Wilden and/or wolves were killing my horse! It died right as I hit the Wilden with a Diamond Axe swing. The horse was felled, but fell short of despawning. I thought to myself, "Thank heavens, they have a mechanism to revive horses!" After what felt like an eternity (like 10 minutes) looking for such a mod, I came up empty-handed. I then thought, "Perhaps I need a fresh perspective," so I restarted the world. To no avail. Frustrated, I took an overnight trip to the nearest coral beach a mere 5000m away. I was greeted upon returning, to my shock and awe, by the deathless demon pictured above.

TLDR: how do I despawn this dead horse?

Salvation at last! Thanks a million!

It picked up the corpse for transport. It's still unkillable when placed back in the world, but a horse corpse heap is much more palatable than a horse corpse garden.

Try catching it with a UtilitiX mob yoinker and see what happens.
