Description
Chao Box has the same qualities of shaping that the containers have, and can only be broken by the Somersault. However, it is painted blue with a Chao face without eyes in every side, the upper side is painted with blue wave lines. In gameplay, the Chao Box does have a special Chao key that can transport the player to the Chao World. There are three container in every stage that are hidden inside wooden crates, behind a secret platform and many more. Once the key is collected, it will get marked on the upper left side of the screen (near the scores), and even losing a life will not make the player lose the key. If the key is not gathered, every Chao Box of the three that the player encounter and breaks, will just give him the key, and not the other special items it has. If the player collects the key from the second container, the third one will give the four animals instead.

Every Chao Box does have his special objects hid inside it. For example, the first one give the Chao key, the second give four animals whether some of them are the same or different. While the third container gives the player the special animal of the playing stage. Here are all of the special animals in the third container, though the "Phoenix" is sometimes encountered even without breaking the container:
