The Spring Hill Zone is a Zone on Mobius, most likely lying on South Island. In the story Time Racer, Doctor Robotnik challenged Sonic the Hedgehog to run half way around Mobius in five seconds flat, something he achieves. Spring Hill is one of the Zones Sonic had to run through. Since it neighbours the Marble Zone and is close to the Emerald Hill Zone (or possibly intended to be the Green Hill Zone, it is possible that the Spring Hill Zone should have been the Spring Yard Zone.
