The jungle is an interesting idea thematically, but it is somewhat underwhelming, as it is hard to find and most of the dinosaurs are weak.

I think it would be a good idea to make the jungle more likely to be found, if not guaranteed by talking to some kind of NPC to get it to appear. I also think if it is going to be a higher level area, the dinosaurs should also be more threatening.

I am also open to any ideas that others may have.
