Well, I've been pausing to think about the jungle for a while. Here's some of what I've decided HAS to be in the jungle to make it... er, jungle-ly.
Ok, first on the list are vines, these are needed so that the jungle feels real rather than a pile of duplicate trees scattered around(and overall, more types of plants)
Fog: the jungle needs this to make it seem "thick"(I have some technical ideas concerning this, possible at this moment).
Creatures: it needs some kind of creature to make strange sounds.
All of the rest is up to you(Justin). This is if you want a "jungle" rather than a "forest" or a "tree-garden/orchard-thing".
