This is a fun little puzzle to solve!
I'm not very good at the garment art and the blood dripping does funny things, but it's good enough for an animated gif when the time comes. Maybe I'll clean that up a little. So to speak. He's more fulla blood than a non-stop communion-wine intake would allow, but more blood means a more satisfying way to conceal how crappy the underlying mechanics really are.
What remains is to section his head into little chunks that fly off in the appropriate directions, give or take a little directionality because we like random effects. There are two eyeballs in there; they start out their lives right by our Poop's eye sockets. There's a nice explosion of blood triggered, and I'll be darned if those particle explosion thingies don't have adjustable gravity attached to them which makes the whole thing a little more disgusting. Yet satisfying. For additional gore I have a few chunks of meaty coyote-skull that'll have to serve as the contents of the Poop's brain. I regret not finding a jackal.
Oh and happy St. Valentine's Day Massacre to you all!
