The Three Little Pigs of fable are three brothers: Colin, Dun, and Posey. They hold a particular grudge against Bigby Wolf, and they are part of the reason that bigby is banished from ever entering the Farm. After they died they needed replacements so three giants were transformed into pigs: Johnny, Lonny and Donny.
Three little pigs left home and each built a house to live in. The two younger brothers were lazy so, one brother made his house of straw and the other made his of sticks. They laughed at their other brother who took a long time to build his house of brick. But when the Big Bad Wolf came he easily blew down the two brothers houses, but they were able to find sanctuary in their other brother's sturdy brick house.
