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?"
