Check it out cautiously.

Who knows if this is the right cave or not! You place your hand on your sword and creep up to the mouth of the cave.
Once you are able to peek inside you notice just what you have come looking for. Inside the cave you can see one goblin girl crafting a pot out of clay while the other appears to be smoking weed out of a clay pipe. The goblin girls are chatting happily and seem oblivious to your presence.
