Located outside of civilization, the jungle is a vast unknown. Many plants never seen, many beasts never discovered.  However, what is known is that one cannot survive alone in this jungle.  There are many poisonous trees and plants and it is impossible to see the sun once in it.  Just an incredible amount of vast, dense and impassable vegetation.

I am a beast hidden in the forest. People often disturb my slumber riding in on horses and shouting. I live deep in the cave and they often come hunting me. I hear them, but they will never find me.
Who comes through my jungle? It is I. Mr. Monster. I seek sustenance, my journey has been a difficult one.  The forests are filled with game. What prey do you seek? Only fruits and vegetables, sir. For I am an herbivore. The occasional carb every now and then. Might you know of some plants that are not poisonous? The flowers of these vines are tasty. I normally eat them with roasted human, but they may be good enough by themselves for you Let me try these flowers...Ugh, disgusting. What do you eat normally in your own land? Well my land is on the outskirts of this jungle and I am familiar with most of its vegetation, such as this grape. I have a large grape orchard on my property, but I was chased away by these little creatures and I seek a new  home. Hm. I'm afraid I don't eat many plants myself. What about all this dense brush here? There's certainly plenty of it if it's good to eat Yes this does look tasty. Thank you Beast, this will provide well for me. And you're sure this isn't poisonous? Wouldn't know to be honest, never eaten it myself ...  Have you ever eaten any of those snakes?
