"It doesn't eat meat." I said. "It's a herbivore. It's like a big cow." Denna looked at me and started to laugh. Not hysterical laughter, but the helpless laughter of someone who's just heard something so funny they can't help but bubble over with it. She put her hands over her mouth and shook with it, the only sound was a low huffing that escaped through her fingers. There was another flash of blue fire from below. Denna froze midlaugh, then took her hands away from her mouth. She looked at me, her eyes wide, and spoke softly with a slight quaver in her voice, "Mooooo."
