Tails and other Mobius citizens are lured into Robotnik’s robotic games of chance, and when they lose they’re sent to slave labor camps. Sonic rescues Tails and the others by beating the house in games of chance at Robotnik’s Casino, and outsmarting the robots in a climactic chase.
Sonic the Hedgehog, the most fearless hero on Planet Mobius, uses his supersonic speed and teenage irreverence to thwart the comedically despicable Dr. Robotnik. Sonic’s idolizing little buddy, Tails, tags along on every fast-action, gag-driven adventure.
