Transformed, Jimmy forces Superman to create a crater in the Antarctic icecap and fill it with heavy materials. Only once Jimmy has reverted to his normal self does Superman discover that as the Cosmic Brain Jimmy had figured that the clustering of the Earth's main land masses around the North Pole would some day lead to the destruction of the planet.
