Sections: 1.Hero A1.Sonic B1.Tails C1.Knuckles 2.Dark A2.Shadow B2.Dr. Eggman C2.Rouge 1.HERO: A1.Sonic: Level 1: City Escape: To find the lost chao in City Escape, you must have Sonic's Mystic Melody. Go to the part where you fall from all of the buildings. When you reach the bottom, turn left and go back. You should see a ruin. Use Mystic Melody, and a spring will appear. Jump on it, and you'll go up a bunch of pulleys. at the top, the lost chao will be sitting down. B1.Tails: Level 3: Prison Lane: You need Hover and Mystic Melody for Tails to find the lost chao in this stage. Go to the part where there are 2 wooden containers and a flying guy. You should see an elevator to your right. Go on it. If you look to your left, you should see a big platform with a ruin. Hover to it. Once you get there, use Mystic Melody. The chao is found high up in jailbars. I forget if you use a pulley, a spring, or both after you use Mystic Melody. C1.Knuckles: Level 2: Wild Canyon: You need Mystic Melody, Dig, iron container breaker. When you start the level, climb all the way to the top of the starting point room until you see an area shaped like a circle. Run around until you see 4 iron containers. Break them. Dig into the painting you see. There should be a ruin. Use Mystic Melody on it, and a portal should open up. There is another ruin, and if you use Mystic Melody, a swirling thingy will appear. Jump into it. There it is. The lost chao. Level 6: Pumpkin Hill: All you need is Mystic Melody. Go to the top of pumpkin mountain. A ruin is at the top. Use Mystic Melody, and platforms will appear. Jump on them. At the end of them, a few normal platforms are there. At the end of those platforms, is the lost chao. Level 14: Meteor Herd: To find the lost chao in this level, all you need is Mystic Melody. Go to the very top of the building with lights (not the place where Knuckles and rouge fight). A platform connected to the building is where the ruin is. Use Mystic Melody, and a blue swirly thing will appear. Jump into it, and you'll drop down in an area made of metal. Soon, you'll see the lost chao. 2.DARK A2.Shadow: I do not have Mystic Melody for Shadow. B2.Dr. Eggman: Level 1: Iron Gate: You need Hover, Mystic Melody, and Iron Container Breaker. Go to area 3. Look to your left, and there should be an iron container on a small platform. Break it. Hover to it, and jump on the spring that appears. Up there, on the platform the spring took you to, start hovering off the platform to your left. You'll see a platform with a ruin. I think you can get it from there. Level 3: Sand Ocean: You need hover and Mystic Melody. Go on the spinning thing. Jump on the place opposing where you go to beat the level. Defeat the enemy, and you can access the ruin. The ruin will take you to the lost chao. Find the rest out yourself. C2.Rouge: Level 2: Dry Lagoon: You'll need dig, iron container breaker, and Mystic Melody. Do everything the way you would for Knuckles' Wild Canyon level. Level 5: Egg Quarters: In order to find the lost chao in Egg Quarters, you must have dig and Mystic Melody. *NOTE: dig power is found in this level! Go to the room shaped like a circle with the moving spike balls. Jump on the big platform which the balls are connected to. A ruin is there, so use Mystic Melody. A blue swirly will appear. Get in it, and I think you might have to dig into a painting. You'll end up in a room with one of those big black things that crushes you. Quickly, run down under it and the lost chao is down there. Level 12: Mad Space: All you need to find the lost chao in this level is Mystic Melody. Somewhere you'll see a platform with one of those tentacle guys. Defeat it, and behind it is a ruin. If you use Mystic Melody, a swirly will appear. Jump into it, and you'll end up in a metal room. You'll find the lost chao soon. That's all I know on finding the lost chao. BYE!!!!!!!!!!
