A big stone attached to a stick; not terribly durable, but surprisingly handy. This simple weapon has saved the lives of many warriors. When caught between a rock and a hard place, why not take advantage of the rock?
Goblin children play a game called bonk-bonk-bash, a rather unpleasant little pastime that acts as a form of population control. Each of the goblins takes a rock, attaches it to a stick and then takes it in turns to thwack their friends with it. This is a traditional household game that keeps the costs of feeding the family low.
