If you come across a dead cannibal or happen to take down one of these enemies yourself, you can then dismember their limbs and make use of them in several ways. Either to make effigies to scare off other cannibals or to cook and eat to stay alive, effectively giving the cannibals the ol' Uno reverse. To dismember, you just need a blunt force or sharp melee weapon, and you simply hack at the limb you want to cut off until it pops off. Or, if you don't fancy that idea, you can take the whole body and burn it in the fire, allowing the player to acquire bones and teeth, which are beneficial resources in their own right; the choice is yours.
