Story: "Sonic The Hedgehog 3 takes place on the mysterious Floating Island which holds many special powers. The source of these powers are Chaos Emeralds. In Sonic The Hedgehog 2, Sonic and Tails thought that they had destroyed the Death Egg, which was Dr. Robotnik’s heavily armored ship. Instead, Dr. Robtonik managed to crash land on the Floating Island. After learning that the island is able to float in the sky by harnessing the power of the emeralds, the Doc decides to steal the emeralds so he can repair his Death Egg ship.

To obtain the emeralds, Dr. Robotnik tricks Knuckles, the guardian of the Floating Island’s Chaos Emeralds/ He also tells Knuckles that Sonic and Tails are the ones trying to steal the emeralds.

Between battling the new types of Badniks and trying to out smart Knuckles, Sonic and Tails have their work cut out for them once they arrive on the Floating Island and search for Dr. Robotnik.

You’ll soon discover that Sonic The Hedgehog 3 is packed with Zones which are three times larger than those found in Sonic The Hedgehog 2. Each Zone is made up of two Acts, and each Act contains dozens of challenges and obstacles for Sonic and Tails to over-come.

Meet Knuckles The Echidna

Age: 15 Years Old
Species: Echidna
Favorite Foods: Fruit (Especially Grapes)
Special Abilities: Discovering Hidden Passageways and Using His Knuckles to Dig.

Knuckles was born and raised on The Floating Island and he knows all of its secrets. He’s strong, athletic and clever. Because Knuckles knows every hidden passageway on the island, it’s easy for him to block Sonic’s path, create extra obstacles, set traps and steal Sonic’s Gold Rings.

Long ago, an ancient civilization lived on The Floating Island. Before this civilization mysteriously disappeared, it left behind many secrets and mystical powers. Being the only living descendant of this lost civilization, Knuckles has become the guardian of the Chaos Emeralds, which are the source pf the island’s special floating power.

Dr. Robotnik’s Death Egg has lost its ability to fly after crash landing on the island. Having learned that The Chaos Emeralds can make his ship fly again, the Doc decides to steal the emeralds. But first, he must make Knuckles believe Sonic and Tails are his enemies, and that they’re the ones trying to steal the emeralds. Once Knuckles believes Robotnik’s lies, he’ll so whatever it takes stop Sonic and Tails."
