The Three little Dragons

There once lived three creatures, the only ones in existence. The almighty dragons. Three disappeared and three miniscule ones arose. As they aged a tiny bit older they constructed a three houses on their own. one was built out of glass, another out of bricks and the last out of metal, unusually. Suddenly, the animals in the forest beside them went insane. First they wrecked the glass house. Then they smashed the brick house. The dragons fled to the metal house in hope the animals would not break into smithereens. They did not. Instead the stormed into the lush forest.
