Jungle overhaul

[Unsolved_]

A slightly more complex jungle overhaul by adding new animals like monkeys, snakes, birds, etc., making the jungle more dense and based on natural wilderness like the Amazon rainforest, new plants like pitcher plants, palm trees and banana trees, or melons and grapes adds and changes the jungle and the plants and makes them more dangerous/challenging. The jungle would also need new trees and tropical fruits, mechanisms such as epiphytic plant growth, spiders and real ants that even crawl around

To expand tangentially on the point about epiphytes, I think something that is generally missing from the jungles and forests are diverse structures.  Currently forests have a canopy, and thin forest floor. The exception to this seems to be when bushes make up the majority of the forest floor.  Having more diverse species in the canopy and the forest floor can greatly improve the character of a forest. 

Jungles have an additional issue in that jungles, or more to the point, rain forests have not just some of the most diverse and dense concentrations of species of any forest floor or canopy, but due to high levels of sunlight and rain, they can support additional layers. At a minimum a rain forest should have at least one distinct understory [the intermediate layer between the canopy and floor] species.  In practice, they have many understory species, sometimes creating more than one distinct understory layer.  In this layer you find many lichen, epiphytes, soft stemmed plants, and short trees [think holly].  This is not an exclusive feature of the tropics as many so called "temperate rain forests" also have understories.
