Invincible Amy

This only works in multiplayer. The first step is to die. Then, before you are re-spawned, Hold the B-button. If you continue to hold it, you will become invincible and kill any other player you touch.

This trick only works as long as you hold the B button down. If you release it, you will lose this glitch and have to die again to regain it.

Secrets

Chao Traits

To raise a chao that is more skilled in either running, swimming, flying, or strength, you must feed the chao a certain type of chaos drive while a chao is still a child. For a fast running chao, feed it more green chaos drives than any other color of chaos drive. For a fast swimming chao, feed it more yellow chaos drives than any other color of chaos drive. For a fast flying chao, feed it more purple chaos drives than any other color of chaos drive. And for a stronger chao, feed it more red chaos drives than any other color of drive. But remember! Your chao must be a child! You can tell if you've done it right, if your chao starts to grow odd extentions on the back of its head.

Chaos Chao

To get a Chaos Chao you must first have your chao reincarnate twice. Then in its third life while its a child give it one of every 21 kinds of animals. Only one of the same animal and dont give it drives then have the alignment to what you want it to be. For a Hero Chaos Chao make its alignment hero for Nuetral Chaos Chao make its alignment Nuetral. For a Dark Chaos Chao make its alignment dark. Then wait for you chao to evolve and a Chaos chao will come out of the Caccoon
