How to Light your Dragon

A little boy has a problem with his dragon: he's no longer able to breathe fire. What to do? How on earth do you rekindle a despondent dragon's flame? The little boy tries shaking him by his tail, and jumping on his belly, and tickling his legs... No joy. How about goading him somehow? - make him angry, fuel his jealousy... Still no luck. Maybe sticking false flames on the side of his face would work - but, no, that makes it all worse. Much, much worse. Now the dragon's downright depressed. Oh no! He decides that he'll just have to tell him that he loves him just the way he is, even though he can't breathe fire, and that he will always be his dragon - and plants a big fat kiss on his cheek. What do you think happens next?
