The Sharp Grey Sheep or The Sharp-Horned Grey Sheep is a Scottish fairy tale collected by John Francis Campbell in Popular Tales of the West Highlands, listing his informant as John Dewar, labourer, from Glendaruail, Cowal.
The stepmother was cruel to the princess and sent her to watch the sheep while not sending her enough food to survive.
The henwife's daughter had an eye on the back of her head that was not asleep; she watched through it and told her mother.
The queen therefore brought her stepdaughter home to work about the house and sent her own daughter out to tend the sheep.
The queen got her daughter's foot to fit by cutting off her toes, but a bird pointed out the blood to the prince.
