Suicide hill
In the mystic ruins chao garden there is a random hill that droops downwards if you feed your chao anouth birds it will try to fly and jump off XD
Golden Chao egg
After you beat Chaos 0 as Sonic, go back to that area and go by the left palm tree. And you should see a rock shaped like an egg(but this is not it). Pick it up go out of that area. While walking along you should see a shop with a gold egg in it(this is it). Make sure you are stiil holding that rock. Go into the shop and replace the gold egg for this one. NOW YOU HAVE GOT IT!!!
Now all you have to do is take to the chao garden in the Hotel. Then hatch your golden chao.
NOTE: THIS CHAO DOES NOT HAVE ANY SPEACIAL ABILITIES, IT IS LIKE IT IS LIKE THE OTHER CHAOS.
Where are you?--Blueworld
With Tails, go to the sewers behind twinkle park and get the shoe upgrade if you haven't already got it, then stand in the road and face the newstand building corner. Fly to the corner. When you are still flying and touching the corner, drop down without holding any buttons. If done correctly, you will go through the floor and end up in a blueworld behind station square. Just as you fall through the floor, fly and do a sort-of sharp left turn to land on a little platform behind the train station entrance. Look around and you can see cars going back and forwards. But when you do this cheat, don't fly too high in the blueworld, otherwise you will be inside the train station entrance tube, and you wont get out so you'll have to do this cheat again. Notes: You do not need the burger man statue for this cheat at all. You can only do this cheat with Tails.
