Blackened, Bumpy and Thoroughly Unpleasant Zone

The Blackened, Bumpy, and Thoroughly Unpleasant Zone is the final fate of the Brown Hill ZoneHill Zone as shown in Sonic the Hedgehog in the Fourth Dimension. This zone is the consequence of Dr. Robotnik altering history.

Description
The zone is now populated by clones of Sonic's animal friends, such as Lightfoot Clone Type B. Sonic and Tails have to lie to this clone that they too were "a special batch" of clones. Notable sights in this zone include hillocks, valleys, new buildings, and a great cliff. The cliff was so slippery that Sonic's shoes could not find a solid grasp on the mountain no matter how hard they tried. Sonic saw no sign of Eric the Echidna in this zone.

Down a long and straight tunnel, past rusting Robotnik machinery, lay Robotnik's own secret laboratory. Inside is an upgraded Egg-o-Matic.
