Antlion Guardian ragdoll that is glowing and green and stuff?

I’ve been wanting to do something with an Antlion Guardian for a while. However I’m not sure how to get a ragdoll. I’ve looked around a lot of folders and didn’t find one and then I didn’t see any bodygroups/skins within the normal ragdoll and I tried using the coloring tool and it looked wrong and then i tried to kill the NPC but it just turned back into a brown Guard on death. So, anybody know how to do this? i don’t mind installing an addon if someone point me to one that works but I couldnt find one that worked thank you
