Hero or Dark Chao
To make a Chao a Hero, simply use a Hero character and keep pressing B or X to pet them. If done long enough, it will go white and be a Hero. To make it Dark, just use a Dark character and do the same thing.
Dark Garden for Chao
Raise a Dark Chao with one of the three Dark characters. Continually feed and train the Dark Chao and it should evolve (creates a tear-shaped "cocoon"). Once it evolves, descending stairs should appear at the main Chao lobby leading to the Dark Garden.
Hero Garden for Chao

Good and evil Chao races
Get a good Chao and a bad Chao to unlock the good and evil Chao races.
Pumpkin head for Chao
Find one of the Skeleton Dogs; the easiest place to do so is the Pumpkin Hill stage with Knuckles, and combine it with your Chao. With either Knuckles or Rouge, start digging around in the Chao Garden. Eventually a pumpkin will appear. If you give it to the Chao mixed with the Skeleton Dog it will put it on its head. If you want to take it off, either throw or hit your Chao.
Wake a sleeping Chao
To wake a sleeping Chao, stand next to it and whistle. You do not have to anger them by picking them up during a nap.
Go to a Chao Garden and get a coconut. Then with a sleeping Chao, pick up the coconut and put it by the its head. The coconut will act as a pillow.
Get the Gold, Silver and Black Chaos from Sonic Adventure
Load Sonic Adventure, then go to the Chao Garden where the Chao you want in Sonic Adventure 2 is located. Put it into Chao Adventure. Load Sonic Adventure 2 and go to a Chao Garden. Go to the transporter. On the VMU with Chao Adventure, there should be an egg. It is the egg for your Chao from Sonic Adventure. When it hatches, it will be back to its first form. The only thing transferred is the name, but the Gold Chao will be gold, the Silver Chao will be silver, and the Black Chao will be black. Note: If you pet or try to influence the Chao you imported, it will lose it original colors.
Full pause screen
Pause the game and press Y + X.
Place the game disc in a PC compatible CD-ROM drive to find several rendered images from the game.
Run on foot in City Escape stage
At the start of the City Escape stage, instead of landing on the ground with the board, scrape the roads on the board. When on foot run full speed at a wall and get knocked down. Pause the game if you fall after hitting the wall. Choose to restart the stage to run on foot and not on the board.
Quickly complete Security Hall stage
In the Security Hall stage you play as Rouge The Bat and are given 5 minutes to complete it. This can be quite difficult. If you have enough lives you can do this trick. If you cannot seem to find the Emeralds, intentionally die. You will keep the existing Emeralds that you have collected. You will begin at the start of the level and the Emeralds will move to different places. This is the fastest method for completing the stage if you are having trouble.
Big The Cat appearances
In Knuckles' Pumpkin Hill stage, go to the one of the train gates. You can see Big The Cat hiding behind the gate, waving to you. In the City Escape stage, Big The Cat appears after the last corner in the G.U.N. truck vs. Sonic scene. Look for him at the right of the screen, running downhill on the sidewalk away from the truck. In the Tails stage where you are running from the police and you first get your hover ability, Big The Cat can be seen again. There is a part in the level where you need to knock a column over in order to use it as a step to reach a higher level, from which you hover over to a platform with a police barricade and two robots. If you miss the platform and fall in the hole, you will see Big the Cat sitting on the girders underneath the platform. You can also see him in the battle against Sonic while playing as Shadow.
In Rouge's Inside the Pyramid stage, one of the robots you blow up is E-102.
