Dragons are creatures that have the ability to breathe fire, water, or lava. Depending on the type. The Dragon is fireproof everywhere but the inside of it. The only fireproof part there is inside the body is the fire hole. The peer of its body that gives it the ability to breathe fire, water, and lava. The hole that lets out the fire, water, and lava is tiny. The hole of the fire hole is about as big as the human eye. But let's out a lot of fire. If you were to be swallowed by a dragon the only chance of you surviving is to plug the two fire holes. This will make the dragon, explode. Literally. But you will survive most likely with a couple injuries.
