Flying Battery Zone

This zone takes place on Eggman's gigantic metal blimp. The blimp is powered by rotating drills and machines that send out worm like bridges. Not too much to say about this place. The mini-boss is a machine that looks like on of the animal capsules. It has two huge ball-and-chain arms. Stand on the switch on top of its head and for it to rear back and swing. Get off the machine and go out on the side with the attacking arm. The second act is basically the same thing but with better music. There's an area where you need to survive by dodging a beam for a set amount of time until it magically blows itself up. After that, you need to race to the top of the blimp without getting crushed by the moving floor. The boss isn't all that hard. Avoid it until it starts to swing over and over. After that it should be pretty easy. When you defeat it, release the animals and watch the scene with Sonic or Knuckles escaping into Sandopolis Zone.
