the Chaos and Sol Emeralds, an extended ending, featuring an extra boss, will be unlocked. Plot On a stormy night, Sonic and Tails set out in Tails' biplane, the Tornado, after it detects a powerful energy signal. During their flight, the Tornado is struck by lightning and gets sucked into a tornado, knocking Sonic and Tails out. They awaken on a remote island and meet the energetic raccoon Marine, who longs to be a sailor. Sonic sets off to explore the island for shipbuilding materials, as Tails starts to work on Marine's ship. Sonic returns and discovers the smaller, faster waterbike that Tails and Marine have made. While exploring the surrounding islands to test the waterbike, they soon encounter a band of pirates led by the robotic Captain Whisker, who are after an ancient artifact known as the Jeweled Scepter.
