In Sonic Adventure 2 Battle how do you get a silver chao into your chao garden?

You can't purchase a Silver Egg in Sonic Adventure 2 Battle in the Black Market. So you have to get one from the Tiny Chao Garden in Sonic Advance. You need a Game Boy Advance-Nintendo GameCube Link Cable to connect. Buy a Silver Egg in the Game Boy Advance and on the Gamecube, step on the red button on the Chao Transporter. Then select Pick Up. The GBA has to be turned ON. Then select the Silver Egg and then select Pick Up at the bottom. You will now have a Silver Egg into your Chao Garden. A Silver Egg is only 500 rings. Or sonic adventure DX has a free silver chao! Ok with sonic or tails go to the mystic ruins and so to the lake. Over their to your left you will see a weird stone thing. Push it (by walking against it). Then turn to the waterfall their you will see another rock release from it. Then it will float to shore and pick it up and take it to the chao garden! (Make sure you take it to the mystic ruins chao garden) then transport it to the gameboy to Sonic Adventure 2 Battle and done!!
