    Stories & Tasks
    Story #1
    I'm Sonic! Sonic the Hedgehog!
    Well, yaaaaaaawn....
    Eggman seemed to have learned his lesson.
    I suppose it's time for my next journey.
    Suddenly, Tails came to me
    in a huge panic.
    What? Angel Island has fallen
    again?
    What's happened this time?
    Anyway, let's go and find out!
    Task #1
    Find Knuckles and Eggman on Angel Island.

    Story #2
    I'm Sonic! Sonic the Hedgehog!
    When I arrived at Angel Island,
    to my surprise I found both Eggman and
    Knuckles lying unconscious on the ground.
    What did you say?
    Chaos is still alive??
    ...And then all of the sudden
    I found myself in another world.
    Just like before...!
    Event #1
    A visit to the past

    Story #3
    I'm Sonic! Sonic the Hedgehog!
    In that mysterious world...
    I saw a girl...
    and many Chao. And an army of warriors
    marching towards the Emerald,
    Then... It was standing in front of them.
    But... who? Who is that girl?
    Event #2
    The visit continues

    Story #4
    I'm Sonic! Sonic the Hedgehog!
    When I awoke, only Tails was there.
    The last Chaos Emerald is still
    inside the Tornado 2!
    I cannot allow Chaos to absorb
    the last Emerald!
    Tails and I ran back to
    Mystic Ruins to search for the Emerald.
    If the vision I saw is true...
    That must mean Chaos is...!
    Task #2
    Go to the Jungle

    Perfect Chaos - Boss
    Collect rings as you go through the flooded streets--if you ever lose all of them, you'll change back into Sonic and "die." Avoid Perfect Chaos' attacks as they'll slow you down and you need as much speed as you can get. Attack at the bottom and if you have enough speed, you'll end up hitting Perfect Chaos' brain. 6 hits and the battle is over. The first 3 are easier to get than the last 3 in terms of avoiding Perfect Chaos' attacks, which increase after the third hit.
