Continued from the Marble ruins zone...
on the quest for the emerald lost beneath the marble zone, Sonic does what he does best in avoiding traps, pits, spikes, lava, etc. meanwhile, the destruction of the Neo Flying battery does not go unnoticed...one of Dr. Robotnik's metallic henchmen quickly gets word (and footage) of his flying battery, sonic, tails, and the missing chaos emerald. Wasting no time, Robotnik quickly assembles a team of previously beaten Sonic 3 and S&k mid-bosses to confront sonic at the Marble ruins zone. In the ruins, Sonic presses on in his search until he spots an eerie yellow glow in which, in his superspeed fashion, races towards the glow. Alas the emerald is isolated in a large open cavern.... as sonic hastily goes to retrieve the emerald, a rumble from above shakes the ground below furiously. A hole is created from the top and the 12 mid-boss baddies descend and surround sonic separating him and the emerald....
