Mobius is still ruled by Doctor Robotnik. Deep in his Scrap Brain Zone, the enormous Terra-Droid is making the Badniks build a terrifying new machine - the Green Eater! The hard work is proving too much for some robots, with one struggling to keep up. In the Emerald Hill Zone, Sonic the Hedgehog is checking up on the latest fashions when when Tails, Joe Sushi and a rabbit show Sonic something. The entire Zone, including their secret hideout is melting! Worse still, a Flicky points out that the grass is dissolving and reveals that the Green Eater plans to bleed the planet dry! "Over my dead body," shouts Sonic as he speeds off, although Tails worries that might be the plan!
