The Jungle Zone boss is a vehicle that appears in the Sega Master System and Sega Game Gear version of Sonic the Hedgehog. It was a modified Egg Mobile created by Dr. Robotnik that the doctor used to battle Sonic the Hedgehog.



The Jungle Zone boss is mostly a regular Egg Mobile. Oval in shape, it possesses its usual windshield, blue seat and wings on its sides. It also has yellow armor on top of the gray rockets on its rear and ventilation holes in the shape of stripes on its front. It also has the usual Egg Mobile's grey upper-half, black underside, yellow circle on its front, and trademarked yellow and black hazard stripes on the sides. The main difference is that it is equipped with a gray cannon on its underside.

Powers and abilities

The vehicle possesses the power of flight and can drop bombs using its cannon.

Boss guide

In Jungle Zone Act 3, after having climbed on top of the vines, the player will arrive in an empty area on top of a U-shaped vine platform. Robotnik will then arrive in the center of the boss arena in his vehicle, initiating the boss battle.

During the boss battle, Robotnik will drop rolling bombs on the vine Sonic stands on. These bombs will roll back and forth on the vine a fee times before exploding. To avoid taking damage, the player has to jump over the bombs while they roll around. When Robotnik eventually lowers himself down at the side of the screen to drop a new bomb before regaining his altitude. He will then hover over to the opposite side of the vine platform and start the whole process over again. Despite hovering above the arena though, Robotnik and his vehicle is not outside the range of the player's Spin Jump at any point, and can thus be attacked at pretty much any time.

When Sonic rebounds after hitting Robotnik's vehicle, the player risks putting themselves in danger, as it can be hard to avoid landing in the path (or on top of) one of the rolling bombs. The player must also pay attention to the bottomless pits positioned at the edges of the vine platform, as one can easily lose a life even after the Jungle Zone boss has been defeated by misjudging the jump off to the right and failing to reach the metal cage's platform.

Once Robotnik has taken eight hits, he will be defeated and flee in his exploding Egg Mobile, allowing the player to open the metal cage and complete the Zone in doing so.
