Sonic Unleashed hidden stages

This could be in-game secrets, but there were entire stages hidden within some of the original night stages of Sonic Unleashed. They can only be accessed through glitches or using your Unleashed guage to do the flying werehog trick. I foung this to be interesting because some of these hidden spots make a reference to previous games (such as the one in Adabat making a reference to section 2 of Lost World in Sonic Adventure). A few of these hidden stages even have goal rings! Some of these were made into DLC's, but it shows that they were planning more for Sonic Unleashed.
