[ It sounds too much like a riddle game and Harry was never very good at those, but he reasons he might as well give it a go. ]

I've got a riddle, if you like:

A creature came where there sat many wise men in the meeting-place.
He had two ears and one eye, two feet and twelve hundred heads,
a back and a belly, a pair of hands, two shoulders and arms, a neck,
and two sides. Now tell me his name.
