History
The Freedom Fighters meet to discuss Dr. Robotnik's latest activity, and notice that he has been quiet lately. Just then, a loud "BOOM" sounds from the distance. Sonic goes to investigate the sound, and finds out that a giant smoke-belching machine, the Wall-Upper 3000, is slamming metal wall sections into the ground.

Robotnik explains that he plans to build a wall around the entire Great Forest and put a dome over it to keep out sunlight and fresh air.

After escaping an attack from Robotnik's robots, Sally proposes that they use a giant magnet Rotor made to magnetize the metal wall Robotnik was erecting. Robotnik's metal Swatbots would stick to the wall. Sonic also has Bunnie paint fake scenery on a canvas to lure the Wall-Upper 3000 to where they want it to go.

Sonic, Antoine Depardieu, and Sally pull a wagon full of Rings to Robotnik and his machine. Sonic tricks Robotnik into getting close to the wagon and whistles, signaling Rotor to come up out of the wagon with his giant magnet. The magnet pulls toward the wall and magnetizes it. Robotnik, because of his robotic arm, and all his Badniks are drawn to the wall. Sonic whistles again, and Tails appears with Bunnie's fake scenery. He holds it in front of the Wall-Upper 3000's eyes, and lures the machine over a cliff to its doom.
