While I'd personally like to keep the Orcs and Gobs, I'd be down for nastier looking prisoners. Always felt the dicks in particular looked too clean and almost rubber looking.Cunnilingus, paizuri, and podophilia of course. Given how the orcs are, it probably wouldn't be hard to make an "ugly human bastard" overhaul. And why stop there? Why not make a cursed garden gnome overhaul for the goblins. As for nerds, making them a white silhouette with the text "typical pineapple pizza enjoyer" scrawled in black over their chests, or "guy who breaks their pasta into the pot", and other L-takes.
We need more dick definition.
