The Casino Night Zone is a massive casino area in the middle of the Badlands, located in an area dubbed Renobotnik by its owner. It was used by Dr. Ivo Robotnik to test his new Orbinaut Badnik by having it subdue Sonic the Hedgehog. Sonic later escaped and destroyed Renobotnik in Casino Night. Two years afterward, Mammoth Mogul obtained management over the casino and renamed it the Casino Night Club after his escape from the New Mobotropolis prison. He then employed Dr. Robotnik's old badnik robots from the Robo Hobo Jungle to act as the staff and perform various jobs, such as waiting on the customers', handing drinks around, and preparing the food.
