Cold and dark, the moist cool walls enclose all who proceed. With just torches to light the way the large opening gets smaller and smaller.
Cave, Cave

I hide in the gaps behind the walls of the castle.  I come out at night to steal food from the castle's kitchen.  When I come out to steal food from the castle's kitchen I have to avoid cats.  The castle cats will try to kill me if they see me come out to steal food.
Don't look now, but there seems to be one heading this way. Oh great. Even in the recluse of the caves, I still have to worry about getting squashed? I know, right? We should do something!  What exactly is your plan here, my furry little rodent friend? Hmmm... it's dark in here, yes? What if we found a way to knock down the torch, he won't see, right? I bet the creepy crawlies that live deeper in the cave would appreciate the dark! Ehhhh, I don't know which is worse. The big scaly things that live farther in the cave, or that pesky human. Maybe if we wait, they'll take each other out? I... gah,,, you;re right. I am just... so tired of hiding from these vile things. I know I know. It's always the little guy that gets pushed around. It's not fair just because we don't have wings or magic or any of that cool stuff! All these low level warriors using us for practice. Beating us up for minor rewards from villagers. It's an outrage! Maybe....what if we banded together with the others out in the fields and swarmed the village all at once?! Ooooh! Interesting! A strength in numbers thing? I like it! If we get enough of us little guys, I bet we could cover so much more that way! Now. How do we get the others on board?
