Zimmix's Great Escape

Wait, wait, don't go yet!

I know I said I just needed the key but... Well, they caught me once, they could do it again, right? I'm just one goblin, and there's hundreds of trolls around here!

You've already put enough of a dent in their numbers to get this key, so it should be easy enough to stand guard while we mosey on out of here, huh?
