Sonic The Hedgehog is on a Power Ring-hunting expedition in the Marble Zone, gathering up their energy to strengthen himself against Robotnik. With his speed and athleticism, Sonic has little difficulty in retrieving rings from their difficult and dangerous positions above the Zone's firespouts and lava-flows. Like all good children's television, there's a valuable, worthy and improving moral lesson to round off the fun. After being smacked, crushed and scorched, Robotnik comes to realise that cartoons rot your brain.
