The stage is notable for its incredible width, which makes getting from one side of the stage to the other quite a long and arduous trek for all but the fastest combatants or those without an otherwise high-speed method of travel on the other hand, the stage's camera doesn't have quite as much work to do when scrolling vertically as is does when scrolling horizontally, though there's still plenty of head room for characters with Super Jumps to use them without needing to worry about going offscreen.

Eggman mostly follows the camera's horizontal movements in his Water Eggman, but briefly disappears below the stage floor when the Water Eggman's tank of Mega Mack empties its contents onto his head, only to re-emerge some time later with a refilled tank and Dr. Sonic and Tails make respective background appearances running eastwards atop the raised platform and being transported westwards via a high-speed warp tube, while Dr. MabsKMK's Chemical Plant Zone uses sprites taken from Sonic the Hedgehog 2, though the ChemicalPlant2 and ChemicalPlant4 definition files recolour the background buildings to match their appearance in the Sonic - The Lost Land 2 ROM hack, while also adding a fog effect that partially obscures the lower parts of certain background objects.
