There is no treasure to be found here. All you see is filth. Dirty murky water and fumes rising from it burns your eyes. You see animals roaming around. Are they small dogs? No they are rodents, big rats. They glisten with the filth they are covered with. It is dark and difficult to see much else.

a rat chews on a dropped hymnbook
I stick to the edge, nose up and ready for any morsels that may drop my way. Or sometimes they don't, but I often don't know until my jaws are upon it. A hunk of moldy crust, the edge of a dropped hymnbook, it is all fair game.
Ive never known your kind to be friends of the rats! I am friends to all who are opposed to humans  I can get behind that my 8 legged friend! We should work to overthrow them! What could a rat and a spider do??!? They are afraid of both of us  Thats true. We would need allies! The mice would be with us - if you will stop eating them  Ha! Im sure youve had your fair share of that delicacy yourself I eat only flies and bugs. I consider it a courtesy to the humans  Hmm. And what of the snake over there? What do you think he would say to your plan perhaps if we asked him nicely?
