Sonic the Hedgehog astrology
No matter what you find on the internet, none of their "bdays" are official (more like first appearances). So, pick a sign and you'll get a character whom I believe to fit his/her sign, but ucan be the judge of that. Even if u don't like what u get, at least let me know if they fit the sign. However, it takes long for me to include pictures and descriptions, so if you're curious, you have the internet to search, but that's up to you.
