Black wolf: amygdala White wolf: prefrontal cortex The black wolf is always hiding in the shadows, and only strikes if there is danger around. The white wolf is always trying to figure out stuff (Putting prey animals' skeletons back together, finding food, etc.) Now both wolves are friends, but the black wolf will sometimes pounce on his friend the white wolf, while he's trying to do something. This can be bad, but you can breathe to calm both down.
