Yay, yet another dragon!!! His name is Firework and is colored basically after an American flag because he's based on fireworks. And when I think fireworks, these colors come to mind.
Also if u think of that stupid Firework song while reading this...that's kinda what inspired him. But not the normal one, NO. There's a YouTube called Jontron (I think) who sang it for a fundraiser thing, and his version is WAY better than the normal one. So yeah... Firework dragon...
