I was trying to top off a candy cane, to get the candy, and it was hollower than I had anticipated. Luckily, out of laziness, I'd put an armor stand in a room at the end of a long hallway. There had been lots of trees, so I'd made lots serrated green glass disks, and I'd lined the hallway (around the corner) with ten traps of ten disks each. I had nearly 200 dwarves, so I drafted almost off them into the military, and sent them to the armor stand. Then I unpaused, and went to play a different video game. I had to unpause once more, because ten goblins showed up on the surface, but I didn't redirect my military. When I came back the goblins had (probably) killed all my dogs and cats, and who knows what else, but the excitement was over, and I still had dwarves alive!
I'd only had about 15 spare coffins set up before it happened, so it took a long time to make enough for the rest of the fort. Many bodies were never found, so I had to make slabs too.
Which leads me to my first question! There were clowns in my list of possible slabs, so I engraved slabs for them. The gray banshees were notable in that their slab always ended with what they liked. One gray banshee was at one with geese! I've seen antelope clowns down there, but never a goose clown. Is this just a side effect of the base creature the clown is based on maybe? In theory, the gray banshee used to be an elf, right?
The more disturbing question came up next. I noticed a dwarf struggling along trying to carry a clown corpse somewhere. But not towards the corpse pile. There were no clowns in the corpse pile at all. So I watched that dwarf, becoming more and more worried. And my worries came true when the dwarf ended up at the butchers. When a dwarf butchers something, like say an elephant, it's pretty much just an explosion of parts that happens instantaneously. But it takes a surprisingly long time to butcher a clown. But whyyyyyyyyyy......why do the dwarves butcher them? It looks like they are only butchering skeletons, to make bones, but, again, why? The bones don't go to the refuse or corpse stockpile, so I had to craft them to get rid of them. And why don't clowns count as corpses or refuse?
My barony is missing now. Had I retired the fort instead of trying to fight to the death, is there any chance I could have reborn my baron as a clown?

Presumably I'll get my barony back at some point.
