Toby the Sapient Pig lived on Earth in the early 20th century. He and his "brother" Alphonse Chardalot were artificially created. Their creator was not from Earth or that time period. The Sixth Doctor and Peri met them in Ostend in 1913. He spent his time on Earth being a stage curiosity touring the theatres of Europe recanting stories. (AUDIO: Year of the Pig)
