A dragon is an evil devious monster that can kill easily with its sharp yellow teeth.
The dragons feet sink into the human bones and swords. The cave echo sounds like kids screaming. His eyes are as big as dinner plates. His wings are covered in holes. His mouth is dribbling with red blood. He has spikes on his back. The edge of the dragons wings scrape against the walls of the cave as he stomps towards the exit of the dark cave. He knows what tunnel to take because the one that goes to the exit has daylight.
Dragons are an animal you would never want to meet.
