1. You have to be Tails to do this. Go left of the antique shop untill you reach a wall. Jump over it and you will end up in a grassy area. Keep doing your tail spin attack around that area and eventually an emblem will appear. 2. You can be any character except for E-102 when doing this one ( I preferred Knuckles ). Go to the mystic ruins, then left of the lake you will see a mine cart. Jump into it and it'll take you to a BIG jungle. On the right side of the canopy, you will see a large tree with no leaves. Get to that area and you'll see a house-ish-type-thing. Then jump on the branches untill you reach the top of the log. In it is another emblem!! YAY! 3. Be either tails or Knuckles to do this. Go to the Mystic Ruins and go to tails' workshop on the opposite side of the runway you'll see a cliff, with and emblem sitting on it. Fly over there and get it. Secret Emblems
1. In the casino alley of station square, fly all the way up to the top(with tails) and you should see and emblem. 2. In the Egg Carrier go to the Captains room click the button and go to both of the nearby doors, and there will be an emblem in both. Other Hidden Emblems
