The Jungle is the fourth stage from Alex Kidd in Shinobi World.
The first area begins on a waterfall which the player must climb up. Midway through the climb is a secret passage which the player can reach using the Fireball technique. Once at the top the player reaches a swamp, with some tough platforming due to the enemies positioning.
The second area is inside of a cave filled with lava. The player not only has to deal with enemies but also fireballs and lava drops which can easily knock the player into a lava pit.
