Please help me! Sonic DX chao problem....?

Question

I've had sonic DX for almost 2 years but I haven't played it in a year and a half due to my brothers destroying the disk. I just recently got the same game and was able to play again. Everything was where is was when the disk was destroyed until I got to my chao garden. My favorite and strongest chao after a few minutes of me being in the garden had gone into a white cocoon with a green stem. I thought it was evolving but it was shaking as the cocoon was forming around it. When the cocoon finally disappeared, so did my chao. I looked everywhere for an egg but there was nothing. What happened?? Did my chao die or is it a glitch? It's done this to me twice and I don't know what to do. Can I avoid this from happening to it again??

Answer 1

R U sure it was white? It's supposed to be grey. Anyways, your chao died. Sorry. But to prevent this from happening again, make sure your chao is having a good life so that it reincarnates. The cocoon will be pink.

P.S. I had to ask that question because none of my chao have reincarnate or died yet on SADX. The cocoon is grey in SA2B.
