Jungle Zone

Jungle Zone is the third zone of the Sonic the Hedgehog for the Game Gear and Master System. As with all other stages in the game, Jungle Zone consists of two platforming Acts followed by a shorter third Act which contains the Zone's boss (and not a single ring).

Description
Jungle Zone is an area of South Island; a huge, thick rainforest, with treacherous waterways, snaking vines, and giant trees. Indeed, Act 2 is a vertical level where Sonic has to climb a massive waterfall, jumping on rocky outcroppings and floating wooden boughs.

Boss
This time, Robotnik attempts to take Sonic down by dropping rolling bombs on a sweeping vine trellis. Keep out of the explosives' way, and attack Robotnik when he lowers his pod down to deploy a new ball.

Sonic Jump games
Although not possibly same zone where Sonic visits first time, Jungle Zone is a recurring zone in Sonic Jump, Sonic Jump 2 and 2012 remake mobile phone games. In the 2012 version of the game the Zone seems to resemble an old Japanese/Chinese Temple. The badniks are Spikes and Bubbles. The boss is the same as the other two zones but shoots missiles before Eggman attacks he then blast up like the other two bosses giving you a chance to attack him.

Sonic the Comic
The Jungle Zone appears in the "Face from the Past" storyline of Sonic the Comic, in issues #51 and #52. It was in this Zone that Metamorphia attempted to infiltrate the Freedom Fighters by posing as Sonic's long-lost brother Tonic. The ruse was quickly discovered and Metamorphia defeated.

Adventures of Sonic the Hedgehog
The jungle appeared in the episode "Zoobotnik" where Sonic pass by it and slip on a banana and find a caveman, Sonic tells him where Tails is and he point at a ship that belong to Katella.
