When Eggman trapped Sonic and his friends within his virtual game world at his base, he hid out in the South Pole for the time being, in order to ensure he didn't get blown to the moon with them. There, while waiting for his trap to go through, worked on tweaking Emerl's functions and capabilities.

Some time later, a meteorite was spotted by Chuck Thorndyke, who assessed that it had a Chaos Emerald inside and that it would land in the South Pole. As part of a competition, Sonic and his friends raced to see who would get the meteorite back to the Thorndyke Mansion. As such, they made a stop at the South Pole in order to retrieve the rock before racing back home.
