Chaos Emerald Chaos

Description

From the previous incident, the President becomes aware of Sonic's existence and views Robotnik's scientific power as a threat. Afterwards, an agent (Mr. Stewart) is sent into Chris' school to pose as a teacher. It is then reported that a mysterious stone that causes a machine to malfunction has been discovered. Robotnik and Sonic's group arrive at the scene and get in a struggle, knowing that the stone is a (green) Chaos Emerald. Soon after, Chris obtains the Chaos Emerald, but ends up falling from a high place, with Sonic rescuing him in the nick of time.
