The blue dragons are my absolute favorites! It took me a while to get one. I've got one mostly grown now.

I still need a female 2 headed also. Then I can breed 2 headeds. Woo!

And then I just need... LOL.

Plus there will eventually be MORE kinds of dragons. I get the idea that the plan is to consistently add more. I saw this post on the Dragon Cave forums by the person that runs the game:
"I was on a streak of once a week before. But then came the replacement project, and I stopped releasing new dragons. I need to get back on some kind of "system" of releasing new dragons, but I'm busy. I thought I'd have less to do once AP tests were done, but I guess not."

I'd love to see some new & different dragons soon!
