Sock Pig

Sock Pig was a toy pig. It was made from a leftover sock with cross-stitches for eyes and a button nose with a stitched-on smile. Sock Pig belonged to Ralph, made for him by his girlfriend. He returned it to her when they parted. Sock Pig was animated into a living state by the Anima. Even after the Fifth Doctor closed off the Anima, Sock Pig lived on. (ST: Sock Pig)
