Puck

We ran after the shaggy black thing, and Ripley (or, if you prefer, Shucky) leapt onto its back and grabbed its neck, twisting it around. It was then that we saw a short little face with pointed ears, wrinkles, and an oversized nose.

"Let go of me!" He shouted in a squeaky voice, and Ripley did. The figure he had grabbed popped up. He was a midget with knobby knees. The shaggy blackness that we had seen was a coat that had probably come from some kind of spitz dog, like a Swedish Lapphund.

"What are you?" I asked. I had never seen anything like him.

"Allow me to introduce myself. I am Puck, part sprite and part hobgoblin. How may I assist you?"
