Cinderella

Cinderella was a fairy tale.

A Lapino, a species that fed on emotion, crashed on a planet. When the TARDIS landed on the planet, it was going to kill Vicki or Steven Taylor to generate enough emotion to power a rescue message. The First Doctor convinced it that there were other options, so they put on a dramatic presentation of Cinderella to more positive emotions on which to feed. (PROSE: Planet of the Bunnoids)
