Tidal Tempest

The evil Dr. Robotnik, with a purpose to build his own robotic empire, chains up the Little Planet, a mysterious formation inhabited mostly by plants and where time has no power. Using the power of Time Stones, Dr. Robotnik returns to the past of the Little Planet and takes it over. Soon after, the supersonic hero Sonic the Hedgehog arrives at the Little Planet to stop the villain. He is pursued by Amy Rose, a pink hedgehog and a big Sonic fan. Once on the Little Planet, Amy finds Sonic, but he shows no interest in her until she is kidnapped by Robotnik’s powerful new robot, Metal Sonic. Sonic chases his metal replica while also collecting Time Stones and destroying the robot-producing machines of the past.

The third location that Sonic visits on his journey around the Little Planet is Tidal Tempest, the submerged ruins of an ancient civilization filled with Robotnik’s robots. Using special poles located throughout Little Planet, Sonic travels to Tidal Tempest’s past, where he destroys the machine that produces Robotnik’s robots, thereby saving the location. In the now good future of Tidal Tempest, Sonic encounters Dr. Robotnik in another modification of his Eggmobile – the Egg Bubble, which he immediately faces in battle and wins.

After winning the race against Metal Sonic on Stardust Speedway, Sonic saves Amy from captivity and after defeating Dr. Robotnik, the two leave the mysterious place together and earn the gratitude of the inhabitants of the rescued world.
