Probably because I'd love to have a Maraquan Chomby :3 And Maraquan paintbrushes are crazy expensive...so yeah :3 Can you paint things "Lutari"? Cause there is a Lutari paint brush? :/
No lutari pets yet. And like someone above said, if you want a maraquan pet, you'd be better off trading a pirate draik custom for a maraquan pet than buying a maraquan paint brush yourself.
Unless you want one of your current pets to turn a certain color
