In the Homelands, the first of the pig brothers constructed a home for himself made out of straw. One day, the Big Bad Wolf came and knocked on the first little pig's door and said, "Little pig, little pig, let me come in." And the little pig answered, "No, no, I won't let you come in, not by the hair on my chinny chin chin." "Well," said the wolf, "then I'll huff and I'll puff and I'll blow your house in." So he huffed and he puffed and he blew the house down. Some sources cite that the wolf ate the pig, but this was not truly the case. The first pig survived and was taken to the Farm along with his cousins.
The three pigs grew discontent with being remanded to the Farm, so they conspired to stage a revolt. Colin's cousins sent him on a mission to Fabletown, working under the guise of a malcontent "pig in the city". His mission was to seek out others sympathetic to the animals' cause and recruit them. Having long ago made amends with the Big Bad Wolf (now known as Bigby Wolf), he took up residence inside of Bigby's studio apartment at the Woodlands.  Bigby didn't relish the idea of Colin leaving the Farm, but he was heavily involved with a murder investigation and couldn't be bothered to bring him back. Colin was one of the few non-human Fables who were in attendance at the 2002 Remembrance Day festival at the Woodland Building. While many of the guests danced away in the ballroom, Colin sneaked into the kitchen to get a bite to eat.  Soon after, Snow White discovered his presence and arranged to personally bring him back to the Farm. Along with her sister Rose Red, Snow White drove Colin back and reunited him with his cousins. It was at this time that Snow White first learned about a secret conspiracy between the three pigs and many other occupants of the Farm.
That evening, Colin was beheaded and his head was affixed to a fence post in the middle of the road as a warning to others. 
- Immortality: As a Fable, Colin is immortal and ceased to age beyond a certain point in his physical development.
- In the original telling of the Three Little Pigs, the pigs were brothers. In Fables continuity, they are actually cousins.
