The Farting Dragon

Frank is a friendly dragon, but he has a problem. Wherever Frank goes and whatever Frank is doing, he farts. Frank does not fart little tiny farts; he farts big, stinky dragon size farts. Because of his farting, his friends are reluctant to play with him, but they do find it funny when he farts. Frank's friend Oliver has a similar problem, only instead of farting, he sneezes fire. When Oliver gets a cold, he coughed out fire, setting the whole forest on fire. What Frank can do to save the forest ?
