Sonic 3 & Knuckles (with voices!) Episode 11: Hidden Palace and Sky Sanctuary Zones

At long last, Sonic and Tails have made their way into the sacred Hidden Palace, the home of the Super Chaos Emeralds and the power source of Angel Island, the Master Emerald. The island guardian, Knuckles the Echidna, is through playing around with trying to trap our heroes and finally challenges Sonic to an open battle. During the fierce contest, Dr. Robotnik finally makes his move and steals the Master Emerald.

Now understanding of who his true allies are, Knuckles leads Sonic to a secret passage that directly leads high above Angel Island to a place known as the Sky Sanctuary. Anticipating this move, Robotnik has dispatched an army of Egg Robos and the fearsome Mecha Sonic in an attempt to thwart the progress of our heroes. It's an all-out race against time as the Death Egg rises once more...
