Chao Container Guide
As you are aware, in Sonic Adventure 2, there are three Chao Containers per stage. In this guide we will detail where to find these containers in each stage!
The first container that you open, regardless of which one it actually is, will always contain the key to Chao World. The second container that you open will contain four random animals from that stage. In the third (and final) container will be the “special” animal from that stage.
This guide was created by Mooncow, and was originally a project started by Fusion which you can see on his website here!
If you want to read more about the Chao Container itself, we have a page for this on the Chao Wiki!
