I'm glad they delight and I hope your players enjoy meeting them! 

One of the players in my group makes cheese instead of carousing between sessions, and these little guys have become his nemesis.

Thank you! Firstly, I wanted it to be clear in the naming that this wasn't a cave, castle or tower. Then I figured keeping it simple and ambiguous is the most flexible. As you or I might want to focus on the stash, the bats, the witches, or the cheese goblins to hook players into visiting it there's room to add "of the..." given the curiosity and motivations of the players.
