This is the third level for "Sonic and Blaze". There are three acts. Well actually the "Boss" isn't considered an act because your just there to beat "Eggman" until he flies away to the next place. So in "Act 1" you have different ways to go. Depending which way you choose will lead you into those locked rooms where you have to beat many of the "Egg Magicians". "Act 2" is the same basically. Now for "Blaze" her soundtrack is different for this zone. It has a remixed version of "Sonic's" song.
