Fan-plot: Robotnik is dropped into a nightmare. He's scared of that speedy hedgehog coming after him. So Robotnik builds an army of robots to find the chaos emeralds to transport himself back to the real world. But instead, that evil speed demon goes around destroying his robots, and steal those emeralds to harness for himself. This must have been a human perspective game, rather than a Sonic perspective game!!! Also explains Madonna falling into this unusual world!!! The humans had to team up to run away from those dastardly creatures!!! I kid, I kid.
