When I first got my Xbox Castle Clashers was the shit and me and my friends would play a ton! I kept my crazy username the Xbox gave me for a while then decided that I would use the free username change to make a clan for me and my friends. CCU stands for Castle Clashers United and I'm Cobra, because Cobras are badass! after I changed my username, I told my friends about the clan I started, but they didn't want to spend 15$ to join my clan. so I ended up being stuck in a clan that was just me, and I don't want to spend money to change it 😂
