Top Ten Sonic the Hedgehog 3 and Sonic & Knuckles Zones

Always have been my favorite zone in the entire game, especially the second act. It is the only zone where you fight against three bosses (Two minus Big Arm, as in S3&K).

It is also the most interesting zone in the game, as it is the final zone of Sonic 3, where it later transits into Sonic & Knuckles and into Mushroom Hill (Mushroom Valley) after Death Egg crashes.
