After 2 full acts and a short 3rd act, this zone's boss is waiting. Like every boss in the game, except for the last, you don't fight Dr. Robotnik, but one of his creations instead. Dr. Robotnik actually rescues Sonic from falling into a pit of lava, wanting instead for Sonic to die at the hands of the Doodlebug Mecha.
