    and flew after Eggman.
    But the Egg Carrier attacked us.
    The Tornado was damaged
    and we crash landed...
    I landed in Station Square.
    I think that's when I got seperated
    from Tails. I'm sure he'll be OK
    by himself, but maybe I should go
    and find him anyway.

    Level Story
    I'm Sonic! Sonic the Hedgehog!
    Oh no, it's Amy!
    Why did I have to run into her now?
    Wherever I go, danger seems to follow.
    She doesn't seem to care
    about that, though.
    She follows me anywhere I go.
    So I have to protect her...

    in any trouble again??

    I can't believe I lost Amy...
    Was she captured by the robot
    that was following us?
    I just knew Amy was going to
    cause me trouble like this!
    But I just can't ignore what's happened.
    Amy, where did they take you??
    Where should I start looking for her?

    I'm Sonic! Sonic the Hedgehog!
    I chased after the Egg Carrier
    to rescue Amy.
    I climbed all the way to the top of
    Red Mountain, but the ship was gone.
    Then, I saw an airplane...

    I'm Sonic! Sonic the Hedgehog!
    Tails made a new airplane, the Tornado 2!
    It's really great!
    ...Except that when it transforms
    it has no landing gear... Ahhh!
    Anyway! We finally managed to board
    This ship is really huge.
    It may take a while to find Amy...

    Level Story
    I'm Sonic! Sonic the Hedgehog!
    Eggman was waiting for us.
    He knew that we would come here,
    so he set a trap for us.
    Now I have to cross Sky Deck to get

    when his monster was defeated.
    So I jumped off the deck to grab him,
    but I just missed!
    I woke up to find myself near
    these strange ruins. Then, a mysterious
    light appeared and led me into them...

    Post-Level Story
    I'm Sonic! Sonic the Hedgehog!
    There was this huge mural drawn on a wall

    I'm Sonic! Sonic the Hedgehog!
    I had an unusual dream...
    There was this girl, and
    she was looking at me,
    filled with sadness.
    What did it mean??
    Whoa, take it easy!
    I have no idea!

    Bosses and Character Battles
    Chaos 0 - Boss
    Hit Chaos' head until he's down for the count. Watch out for his spinning and reaching attacks.

    Egg Hornet - Boss
    Story: I'm Sonic! Sonic the Hedgehog!
    I ran across the Emerald Coast
    and found Tails,
    whom I haven't seen for a while.
    He had a great idea about creating
    something using a Chaos Emerald.
    He just loves making machines!
    What?
    He has a workshop in Mystic Ruins?
    OK, I'll go visit it if you want me to.

    The Fight: Avoid the missiles and the eventual charge by the Egg Hornet. When it's momentarily stuck in the ground, hit Eggman. Repeat until the fight is over. There will be more missiles to dodge after each successful hit.

    Knuckles - Character Battle
    Story: I'm Sonic! Sonic the Hedgehog!
    I've found another Chaos Emerald in Icecap.
    Now, I have 2!
    Fantastic!
    Now, where should I go next?

    The Fight: Hit Knuckles 3 times to end this battle. Knuckles will attack more after each hit, including a glide attack after being hit twice.

    Chaos 4 - Boss
    Story: I'm Sonic! Sonic the Hedgehog!
    Knuckles appeared out of
    nowhere and attacked me!
    Why?? Why would he do that?
    That Eggman must have tricked him again!
    Eggman took the 2 Emeralds
    I'd collected, and now Chaos has
    probably transformed again
    using their power!
    OK, show me how strong you
    think you are now! Come on, Chaos!

    The Fight: Attack Chaos 4's head when it's stationary in the water. Repeat until he's down for the count. Avoid the attacks, particularly the energy attacks that span the water.

    E-102 Gamma - Character Battle
    Story: I'm Sonic! Sonic the Hedgehog!
    I finally found Amy!
    But then Eggman called another robot.
    Me, worried? No way!
    'Cause I've never lost to Eggman!
    I'm not sure why Amy wanted me to stop,
    but she must have had her reasons.
    Suddenly, the Egg Carrier began to
    shake! Tails, you and Amy escape before
    the ship crashes!!
    I'll take care of Eggman!

    The Fight: Hit Gamma 3 times and the fight is over. After each hit, Gamma will attack a little more.

    Chaos 6 - Boss
    Story: I'm Sonic! Sonic the Hedgehog!
    Eggman escaped to the bow
    of the Egg Carrier. After
    I transform the ship back to its
    original form, I'll chase him down!
    Nobody can stop me.
    Nobody!!
    Eggman, you won't get away this time!

    The Fight: Destroy Eggman's ice bots and throw them into Chaos 6's mouth to cause it to freeze. Then attack Chaos 6. Repeat until Chaos 6 is down for the count. Watch out for his attempts to suck you into his mouth, his attacks with his tail, and his energy attacks that span the ground.

    Egg Viper - Boss
    Avoid the laser fire (twice) after each of the early hits and don't fall off the platform during the fight. Do this fight quickly, especially after one platform is removed by the Egg Viper and you'll need to ride spinning disks to attack Eggman on the Egg Viper. At the end, it'll do a "suicide dive" in an attempt to kill you (which will cause you to have to do the fight all over again if it's successful). You need to have a few platforms left to survive the "suicide dive"--if you only have one platform left, you're dead.
