Something has been bothering me. Almost everybody has that annoying zombie signature. Just saying. Also, Is it possible to create a Big chao? I just wanna know this so I can make one and abuse it... For reasons.

Alright. I tried some of these, But most of the time, My game would freeze. Do any of you know why?
Another thing! I have the Xbox 360 Sonic Adventure 2 Battle version. Alright then. I hope for a reply.
