I'm going to have to say the bird-type animal.
theres more then 1.what bird do u mean?parrot?peacok?condor?bat?phonix?what?
well if u have an action replay 4 gamecube then your wish is granted.this code makes the first chao ever born into a phonix chao.
note:if u dont want your first chao to change then start another file on another memory card and make the chao there then move it to your regular file with the move function.
Hey thank you and if you go to GSCentral.com you can make your chao anything incluing the Dark and Hero chaos.
