Where do the dragons get the helium? The only helium that exists on earth is there because it comes from radioactive decay, so it would have to seek out uranium and thorium. Even if it was perfectly fine with that radiation, uranium is a heavy metal poison besides being radioactive, so good luck with that. If you actually make it do that, find a way to help that evolve the bloodlust for gold and jewels.
