Well, as mostly of you may already know, because this is a pretty famous and old game, enemies level with you, so the exp is adapted to your level, also de munny.

At deep jungle, you'll find some girly heartless apes that will give you an unlimited amount of munny each time you fall walking over the bananas they threw, so you can make thousands of munny in a pretty short time.

Leveling here is just pretty easy too, where you find the dark fruit, you can get unlimited spawns and this will boost your leveling!
