To get more rare items in the Black Market you need to get more emblems. A great place to get rings is Tail's mission "Route 101" because theres no robots to hit you and make you lose rings. To be able to play as all the characters in the Chao Garden you need to get the Chao key in there mission. (if you want Sonic you need to play a Sonic mission and get the key there) To get the Hero Chao Garden you need to raise a Hero Chao, same with the Dark Garden except with a Dark Chao. To get the forth level of Chao Karate you need to win the other three levels. To help make your Chao happier put the Chao in the Chao Kindergarten, it will learn how to do things like, sing, draw, play instruments, and other things that they can do in there garden!

First get a Chaos Drive or an Animal. Pet your Chao so it doesn't move, then pick up the Animal or Chaos drive, face the Chao and put down what your holding in front of the Chao. It will get the stat increase but the item will still be there!

Some say that Chao have genders, however this is not true. It's also said that there is a blue Chaos Drive that raises all stats, this is incorrect too. Some people think that some how you can unlock a mini movie Called "Chao in Space" but sadly this is not true.

In the Neutral Garden, you can fall out of the garden. To do this, you need to go to the corner of the garden (the flat, stone ledges with bushes on them) and jump into the corner repeatedly until you fall out.

In the Dark Garden, there is a tree with a cage hanging from it (When you just enter, it's to the right). You can jump into it and hang there. This can be done with any character, and you can even use Chao.

A Poly Dynamic Chao is a Chao that takes no set shape (pictures below). The more you pet it, the more it changes colors and changes shape, it also gets smaller. To get this strange Chao, all you need to do is transfer a Chao Egg from Sonic Adventure 1 via VMU and then import it on Sonic Adventure 2. If you don't want a Poly Dynamic Chao, don't worry, it goes back to normal after evolving.
