The light doesn't pierce the heavy overhanging trees in this near pitch black area of the swamp.  The water is extremely murky and there are occasional fins poking up from the water belonging to some kind of creature.  The air is thick and heavy and insects constantly buzz about.
Darkest part of the swamp, Swamp

insects
I am a insect that eats other insects. I have a simple mind. I do not know how to jump because my parents never taught me.
Hello creature, what creature are you? I am a creature that scurries about with no one noticing. I spend most of my time in the darkest corners of the castle. Sounds scary. Will you eat me? I am a creature not a monster. I do spin my webs to annoy humans sometimes but I am a gentle beast. Are you a spider? I am friendless in this damp and dark swamp. Will you be my friend? Aww... Of course I will. You are the first one who wants to be my friend. You are so kind. I wish I could have a hug. Don't hug me, you're an electric eel. No, I am not. The eel is over there. Can I confide in you now that we are friends? Yes. I am sorry, it's too dark in here. I can't see you clearly. Flies are my favorite snack, I only care about myself, and I have no friends. Furthermore I think you will make a rather tasty meal.
