Isn't the "Unused Corridor" in the underground part of Casinopolis accessible by Sonic? I'm pretty sure it's closed off for Tails as it leads almost directly to the end of the stage. I'm also pretty sure that the corridor at the end of Final Egg is used for the cutscene immediately before the Egg Viper battle. MuteKi
