The white one spoke briefly to Lyra, and pointed a hoof at the back tray on the cart.  Their voices were similarly pitched, so he assumed it was also a she.  Lyra nodded, and turned her head.  Dale drew a deep breath as the tray was enveloped in a golden glow and floated up off the cart.  He watched it slowly glide towards her face.  When it was near her left eye, she began walking towards the seat she’d previously occupied, the tray obediently hovering along beside her like a miniature flying saucer.
