The Three Little Pigs are the noted house-builders of fairy tale fame, who have frequently appeared on Sesame Street opposite their nemesis the Big Bad Wolf, most notably in Sesame Street News Flash segments. They are not to be confused with the Five Little Piggies, the quintet of toe counting fame who live elsewhere in the forest; like their fellow porkers, however, the Three Little Pigs have on occasion said "wee wee wee" all the way home.
In a 2007 episode, Abby Cadabby calls the three little pigs on her "cell wand," at which point they reveal their names to be Iggy, Wiggy, and Melvin. Subsequent appearances often included a female pig as part of the previously all-male trio.
The pigs have been performed by various puppeteers, including David Rudman, Kevin Clash, Frank Oz, Joey Mazzarino, Martin P. Robinson, Eric Jacobson, Jerry Nelson, Richard Hunt, Stephanie D'Abruzzo, Matt Vogel, and Noel MacNeal.
In 2008, the Three Pigs began making various background appearances on Plaza Sésamo.
