Sky-Sheep
From Tardis Wiki, the free Doctor Who reference
The Sky-Sheep were visited by the Eleventh Doctor and Amy Pond. They were there when the Space-Wolves arrived with guns and attacked these rainbow-coloured sheep with spindly legs, and the story of their adventure proved thrilling enough to entertain the story-hungry Book Monsters that the Doctor encountered when returning his overdue library books.
