The jail entrance is massive with a huge fence. There are guards on all sides. There are barbs and dangerous things surrounding.

rat
I live near the docks on the edge of the city.  I steal food from cargo boxes that are loaded into ships at night.  Sometimes rats from strange lands come off ships that come to the dock.
What are you doing here, sir? A talking rat, eh?  What'll they think of next!.  I am good friends with the king, and am on the way to see him. Ohh quite important eh? What for? What business is it to you, rat? Just curious, it's boring down here looking for crumbs on my own. And how did a talking rat come to guard the dungeon? Guard? Like I said, I come here only for the bits of food I can scrounge.  well, I have none for you.  I am a bit turned around: which way to the King's chambers? Well that will be up the stairs and then you can see a guard guarding his room. Thanks.  How is it you came to learn how to speak? I just picked it up as I overheard people talking here in this dungeon. You know, we could make a lot of money, you and I, and then you wouldn't have to scrounge for scraps
