There are three islands with Dragon challenges:
Astro Knights island
Climb the chains to the back of the dragon, Dodge the spike ball, and pull the lever to temporarily stop the dragon's flames. Very quickly jump in front and fire the Ice Arrow into its open mouth. You have to repeat this twice more, climbing over the dragon and then shooting into its mouth.
Counterfeit island
Collect the six pieces of the dragon face picture, the last from the museum supply room. In the underground at night, open the dragon face lock by matching the face to the picture.
Red Dragon island
Fly the blue dragon to spray water on the Red Dragon and extinguish the fires it starts.
(see the related questions)
you have to defeat the mechanical dragon.
All you have to do is not get hit trust me you cannot push him off
You jump on the lava rocks, then stop on the 4th one. Jump to the 6th one WITHOUT jumping to the 5th one. Then you defeat the dragon with the ice arrow.

If you have already defeated the dragon then there is nothing you can do, but if you didn't defeat it then see if the person who created poptropica has a e-mail address and email him what happened.
The Leviathan Dragon is able to defeat a Coolfire dragon in the Dragon City.
