Erin watched carefully as a pony trotted into view, smiling gently as she trotted along. Now that she could take a closer look, she noticed that the pony looked only superficially like a pony from Earth. This one's head was rounder, with larger eyes and a higher forehead. Also, horses and ponies on Earth didn't smile, in her experience. Nor did they have what looked like a tattoo of a four-leaf clover on their rumps.
