Eldorado is a dragon who sneezes and lights up like a light bulb when there are strong smells, dust, or nose-tickling feathers. But his friends have stopped inviting him to go places because he ruins their fun by glowing. This makes Eldorado sad. So, he tries to avoid all the things that make him sneeze and glow-even the things he likes! But one day, Eldorado discovers that his gift for lighting up is quite a good thing after all.
