I don't know how much work this stuff would take and excuse me if I sound like an idiot. Could you precache an ant lion and get it to spawn with a physical constraint on a player. It would be like having an ant lion on a leash. This could be for admins only. Or players could buy it. Same goes for zombies and maby even viscous npc's wouldn't alex on a rope be something we all dream of... <--- did I say that?
