Makin a mod where enemies that die in the sun turn to stone instead. It has lots of integrations! Any ideas for additional features?

Random ideas: 
* Ability to move them around
* If they stick around indefinitely, config option to let them disappear after x time, and way in game to destroy one (probably just pickaxe)
* If they would disappear over time, way to make one you like stick around
* Ability to carve faces into them (predefined set probably)
* Dye them different colors
* Different types of stones – biome based? 
* Thrown potion that would apply the same effect to an enemy after it dies without needing the sun

Maybe make them decay into actual blocks? That way they can stay forever in the world? Either slowly make them shed or make the model crack over time and snap, they turn into sand/gravel/cobble or whatever material you have for them

Whats even more fun is if you have structures or villages etc you can make those mounds appear there as if something else was fighting there, you could spawn a village with a half broken golem and 2 mounds, or an ancient structure with dozens of them

After some time they become a half stone half monster amalgamation. Kind of like the stone is a virus that takes them over

When theyre done ‘incubating’ their skin is flaked with stone, and they’ve gained different sounds and movement. Imagine imagining the stages of infection a lot like how last of us does it

Imagine if when the player pillars up the stone monsters kill other monsters and pile the statues up like stairs

Add a hard to craft item that un-petrifies them at night, so you can fight them again or lock them up
