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 curved vine. Robotnik will then arrive at the center of the boss arena on his Egg Mobile, initiating the boss battle. Going to the left edge of the boss arena, he will then slowly descend before dropping a bomb from its cannon and regains his normal altitude. These bombs will roll over the vine from one edge to the other before reaching the center of the vine and explode. Robotnik will then hover towards the right edge of the boss arena and restart the process over and over again, albeit in a opposite direction each time, until he's defeated.

The boss needs to be hit eight time. Even if he's within jump reach all the time, the player must be careful not to bounce back right into the bomb's way after hitting him.

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.
