Chao Basics To gain access to your Chao, te must venture into Chao World. To go to Chao World, te must find a 'Chao Box' in one of the levels. When te break open the Chao Box, te will find a key inside. When te collect this key, te will be warped to Chao World at the end of the level.
There are three Chao Boxes in each level. The first one will contain the key to Chao World. In the secondo box will be four random animali from that stage. In the third (final) box will be the "special" animal in that stage. See the animal sections for più information on this.
