For the Wither Skeleton, you can make it similar to minecraft's regular skeleton, with splotches of ash and burned pieces of bone on it. You could also cover it in moss and vines. Or, you could make it look like a buried fossil that's just come to life.



For the strider and hoglin, you could make them somewhat prehistoric looking. Like dinosaurs who have been hiding underground. Also, the hoglins' hide should look similar to what the cavemen wear. Ghasts could be uh, I honestly don't know lol. That's gonna have to be on you chief.

I love this idea! The caveman is such a good fit

Maybe the ghasts could be I don't know, floating vine spirits? And the wither skeletons could be well, moss covered skeletons with Scabbards, like from that one Spy Kids movie.

make the hoglins more dinosaur lookin

Wow . . . impressive
