Jungles are lush, tropical forests in usually warmer parts of the world, but there are some exceptions. Many are very large, whilst others are very small. Most are found in the tropics, whilst others are found far to the north. Whilst always found in the tropics, they are not always hot (tropical rainforests, a form of jungle, always are). In-game, there are a number of jungles, though none so far seem lush enough to be counted as true tropical rainforests.
