== Premise ==
It's almost the opening day of Carnival Island, a huge amusement resort with the latest in high-tech rides and games. As the guardian of the island, Knuckles' job was to make sure nothing went wrong before the grand event. Behind the scenes, however, Dr. Robotnik was cooking up a new dastardly scheme. To fuel his latest diabolical device, Robotnik went to Carnival Island to find the Power Emerald that supplied electricity to the entire island- a tool which would fit into his plan perfectly. When Robotnik manages to capture Sonic and Tails, Knuckles consults in a notorious detective team called The Chaotix, and they set off to save the island from Robotnik's grasp.
