This is why when hunting, it pays to have a Cold Steel Trailmaster knife on your belt in case you have to engage savage critters in hand-to-hand combat. Then you could have easily lopped off his head and cleaned it out, dyed the skull with red ochre, and mounted the skull on your quiver. With the right chants done over it, it would be a powerful hunting charm to protect you against other critters. I can't tell you the chants to be said over the skull since you have to compose those yourself while burning a mixture of dried pine needles, oak leaves, and Port Orford Cedar shaft shavings. But if you don't use Port Orford Cedar, you can use the shaft shavings of your last batch of arrows. If you threw away those shavings, you will need to make another set and save those shavings and, from then on, never throw shaft shavings into the trash or the medicine will be rendered ineffective. From then on, shafts shavings must be used in this smudging mixture or left upon the ground outside beneath an evergreen tree under a full moon that causes coyotes to howl. Anyway, you have to burn this mixture in a stone bowl or an ivory white seashell. You pass your bow several times over the smoke and the bow then tells you the chants. Trust me, this works. But you can't ever share the chants or they lose their power. It's ok for your arrows to hear the chants and the bow already knows them since he/she told them to you.
The skulls of larger critters can be done the same way, except a deer skull is too heavy to hang on your quiver and the antlers snag on tree limbs going through brush. That skull you must hang on your wall and place arrows on the antlers. Any arrow that passed through game must be put there as well as "Robin Hooded" arrows (both the arrow struck and the arrow that did the striking.) If anyone asks what that means and why the skull is there, they must be told that it costs 100 shafts to find out and that if so much as one shaft cannot be made into an arrow, they cannot be told. For this skull, you have to make another chant for it and this chant must include mention of arrows that strike rock-hard tree stumps yet do not break. And, again, it must be painted in red ochre. While you are painting the skull, you cannot listen to any music that discusses fire in any way whatsoever.
If you do all of these things, you will find your hunting and shooting to be much better. You will not be troubled by rogue animals or human beings trying to picnic under your treestand.
