Bogie

From Tardis Wiki, the free Doctor Who reference

A bogie was a kind of shape-changing goblin. As fantastical creatures, bogies were brought into existence on Avalon by the nanobot system on the planet, which brought to life the fantasies of 22nd century human colonists. The Avalonian Bestiary listed bogies among the animal life on the planet. (PROSE: The Sorcerer's Apprentice [+]Loading...["The Sorcerer's Apprentice (novel)"])
