Animated scarecrow (Human Nature)

The Family of Blood used animated scarecrows as mindless soldiers through the power of molecular fringe animation in rural 1913 England.

Biology
Made out of sack clothing filled with straw for bulk, which Son of Mine used as inanimate materials to put into humanoid shapes, scarecrows were given simple life; this included rather basic motor and sensory abilities through the process of molecular fringe animation. They also had "eyes" that came with limited vision. Shoes provided their straw-filled legs with a strong base. Feeling no pain, these scarecrows will march without an end when advancing on enemies, but when shot-up badly, they collapsed—falling to the ground. On that note, any scarecrow that so much as loses humanoid form cannot come back to life, even with Son of Mine's simple resurrection command — "Reanimate!"

History
Jeremy Baines of Farringham School for Boys had already stumbled across their ship and had his body taken over by Son of Mine.


 * Son of Mine implied that he had created the walking scarecrows while occupying Jeremy Baines' body.

The Family then used scarecrows to abduct humans to be used as bodies for the incorporeal Father, Mother and Daughter.

The scarecrows were used as an army to attack Farringham School for Boys, where many were shot down. Eventually, they re-animated to do more of the Family's bidding. They were presumably made inanimate again after the Family's defeat. Son of Mine was himself turned into an immobile living scarecrow (of a different kind) by the Tenth Doctor.
