Walter was a different dragon. He didn't have a pair of wings like all the other dragons at his school. Instead, he'd been born with a single umbrella-shaped wing on his back.
This had caused Walter plenty of hurt feelings. The other dragons always made fun of him. One hot summer day, Walter's bullies approached him. They were going to burn his umbrella-shaped wing right off!
Then, the clouds joined and darkened, and rain began to fall in torrents. Walter's bullies screamed in pain, as water was a dragon's greatest weakness.
Walter's umbrella-shaped wing shielded him from the downpour, and he laughed as his bullies met their watery demise.
