No it's not out yet.
Supposedly we're supposed to be getting the Griffin pet pretty soon and when it comes out we should be able to pick its color. Should.
Here is a pic of the Griffin creation options from the JP/CH? server. Supposedly the top first option is the mane color, the middle the body color, and the bottom the feet color. If someone could clear that up for me for sure that would be awesome.
So what color griffin do you want?
Personally I want red for the body and white or grey for mane and feet. Red griffin FTW.
