Skinning

If you possess a varmint skinnin' knife you'll find that many of Loathing's snakes and cows can be skinned.

Snake Skins
Snake skins can be applied to your hat for an additional benefit. Choose wisely though, once applied you cannot remove or change a snake skin benefit from a given hat.

Cow Skins
Removed from their infernal bodies, cow skins can be used by a suitably trained Cow Puncher to craft various leather goods. The quality of the goods depends on the quality of the leather, which in turn depends on the infernality of the cow.
