Discovery Zone

The Discovery Zone is a 1930's alternate zone that Sonic unwittingly entered after following a body-less leisure suit, and had a brief adventure there before leaving. It was from this event that Sally believed the malfunction of Dr. Robotnik's Ultimate Annihilator had destabilized the dimensional barriers between parallel realities.

Trivia

 * Sonic’s time in the Discovery Zone seems to roughly follow the Humphrey Bogart movie, Casablanca.
 * Some of the robots that Sonic fights in the Discovery Zone are parodies of the robot hosts from Mystery Science Theater 3000, including Crow and Tom Servo. The Robot 5-9 from the television series Lost in Space can also be seen.
