Fergus here. Achaius has volunteered to be a research assistant in this project. I know some modular furs can have more than one head. Before we explored "when do you still control this body part?". If you have multiple heads, that's still an interesting question when everything is still attached.
Which heads control what body parts? A hive mind probably has the simplest answer to that. Also I hope Achaius recovers well. That kick definitely broke a few ribs. He's still eager to do more field work soon though! ------------------------------- This text is kind of hard to read. So hopefully this helps. Panel 1: Hydras are good subjects for exploring the mechanics of multiheaded furs. We can discover the different ways their heads share their bodies. Do not try this at home with your hydra. Panel 2: Multi-heads almost always share complete sensation of the entire body. But the rules for control may vary. It's possible this hydra is very uncoordinated. Panel 3: Unfortunately for our researcher, this hydra is a hivemind. Each head shares thoughts and control seamlessly. Evasion is unlikely. ---------------------------- It took me longer than you would expect to get this done. Hopefully it explains these ideas well.
