Poem girl
From Tardis Wiki, the free Doctor Who reference
"A horse and a man, above, below. One has a plan, but both must go. Mile after mile, above, beneath. One has a smile, and one has teeth. Though the man above might say hello, expect no love from the beast below..." - The Poem Girl's poem
The Poem girl was a girl on a screen who recited a poem about the Beast on a vator in the Starship UK When Timmy tried to use a vator to get to London and was sent down to the Beast. Whether or not the girl was alive at the time is unknown. (DW: The Beast Below)
