Basically if you have the name of any animal in your Gamertag. i.e. mine is "M0NKEY" R4NGER.
I'm sure with most people that you have the animal name in your Gamertag for a reason. Some form of like/love or fascination with the animal. Or just because it was funny to put. Either way as long as you have an animal in your name, your welcome here. :-)
