What is the locked thing on options of sonic colors?

In Sonic Colors, the locked thing in the options menu is the Super Sonic option. This option allows players to transform into Super Sonic, a powerful golden form of Sonic that has increased speed, strength, and abilities. However, in order to unlock the Super Sonic option, players must first collect all of the Chaos Emeralds in the game. Once all of the Chaos Emeralds have been collected, the Super Sonic option will be unlocked and players will be able to transform into Super Sonic at any time by pressing the X button on the Wii Remote.
