Chao Gardens

The Chao Gardens are the area where your Chao live.

Accessing the Gardens (Sonic Adventure 2 or SA2: Battle)
There are two ways to access the Chao Gardens.

The first way is by going through a stage and finding a Chao Box and breaking it open. If your Sonic or Shadow, you can somersault into it to break it open. If your Knuckles or Rouge you can punch or kick to break it open. If your Tails or Eggman, you can shoot the box with the Missile Attack.

Breaking the box will release a Key. Grabbing the Key and beating the stage will bring you to the Chao Lobby. From that point on, there will be an entrance in front of you that leads to the Garden. Just walk right through and then you can access it. In every Chao Garden, there will be a system with a button on it for transferring Chao.

Neutral Garden
This is the first garden you start out with. It can hold 8 Chao total, and there are 2 Eggs there. There are trees with Chao Fruit/Nuts to feed your chao. There is a pool of water, and a waterfall. Behind the waterfall is the entrance to the Chao Stadium.

Hero Garden
The Hero Garden is the Chao Garden opened when you raise and evolve a Chao into a Hero Chao. There will be a couple of trees there that have Chao Fruit/Nuts growing on them. There is a pool of water, and a fountain in the water too.

Dark Garden
The Dark Garden is the final/next (Depending on the first Chao you evolve)Chao Garden opened when you raise and evolve a Chao into a Dark Chao. There will be a couple of trees there that have Chao Fruit/Nuts growing on them. There is a pool of so called "blood", it's surrounded by a sky of darkness and an evil looking mountain, and the garden has multiple graves in it.
