Chao Container #1
After the first checkpoint, there is a room where you can see the Chao Container on a ledge near the side. Use the lift or the wooden boxes to reach it after defeating the G.U.N robots.
Chao Container #2
In the more open section of the stage, right before the third checkpoint, there is a lift on the right of the path. Jump accross and you will reach the next Chao Container.
Chao Container #3
The final Chao Container is right next to the GOAL ring at the end of the stage! At the part where you use the rocket to blast open the doors, don’t go too fast through or you might launch straight into the ring and end the stage!
