Two-faced Statue
Statue in Hang Castle: As either Team Sonic, Team Dark, or Team Chaotix, enter the Hang Castle level. Play through the stage until you get to the statue of Eggman. Then, flip the castle upside-down by using the nearby switch. Note: You cannot flip the castle here as Team Chaotix, as the statue will already be flipped over. When you flip the castle over, you will see a different statue. This is a statue of Metal Sonic, the real Boss of the game.
