Primitive tribe called Scrubs that spends days collecting every trash they come across. When they are ready, they ambush a caravan and sell everything to them. Then they take off with pay, leaving merchants only with tin cans, empty bottles and paperweights. They dump everything they earned on huge piles in their caves, mostly never touching it again. In battles instead of using stimpaks or drugs they just chew 10 cans of spam and return to fight.
