To get the Crystal Ring For Sonic, first get the light shoes. Then go to the hotel and charge the light dash. Then go up the sstairs. the view should change, shoing a closed door and 2 buttons. push the button closest to you (not sonic) and rings will apear. then get ready to light dash! Push the other button and light dash then run in the door. There will be the Crystal Ring. get it and it will decrease the time needed to charge for the light dash. It will then look like Shado's Ancient Light from Sonic Adventure 2 Battle.
Once you defeat an enemy, an animal will appear. Once you capture the animal, it will appear on the bottom right of the screen. After each level, if you go to one of the Chao Gardens, the animal will be released and you can give it to one of your Chao to play with. Depending on the animal, your Chao will learn special abilities and will take on the appearance of the animal. If you let it play enough with the same type of animal, it will continue to gain levels in that ability. For example, if you keep letting it play with the penguin animals, it will gain experience in swimming and flying. Your Chao can also gain experience by certain fruits which you can buy at the black market.
You can easily access just about any of the highest places otherwise inaccessible to Sonic. All you need is a slope going up or some stairs. Start a spin dash as close to the slope as you can. Pause the game while the spin dash is at full power. Then unpause it and quickly jump when he gets on the slope to really soar in the air! This is all that's needed to reach most inaccessible areas. If done just right, you can actually get on top of the building of the train station with Sonic! This could also be used to take shortcuts in Sonic's stages.
If you want the gray chao instead of the gold chao, go to the site where Sonic faught Chaos for the first time, get that gray stone behind the wall that you would normally use to get the gold egg in the pawn shop.
