Pop!

what looks like a camp fire, under the stars and clouds with forshadowing shadows (lol) on them.
what looks like an old fashoined popcorn popper with lots of roundish brown things in it, is being cooked in the fire.
in the smoke of the fire, you see the stories being told
the story of the history (real or makebelieve - I will work on this part) of how popcorn came about.
in the end the brown things all pop open to white fluffiness.
Then a baby dragon and his parents/grandparents/family eat popped potatoes they have roasted in their fire.

throughout the story of popcorn, there is a hidden dragon watching, or maybe a dragon symbol or something in each picture, always different, like on a flag, or carved, or in the trees or river. Just something fun to make it forshadowing, that they can go back and look for.

or maybe the history will be legend, and include a dragon inventing it or something.
