In a 1979 interview with The New York Times, performer Frank Oz outlined Piggy’s biography: “She grew up in a small town in Iowa, (most likely Keystone, Iowa); her father died when she was young, and her mother wasn’t that nice to her. She had to enter beauty contests to survive, as many single women do. She has a lot of vulnerability which she has to hide, because of her need to be a superstar. ” During development of The Muppet Show, Oz assigned a hook for each Muppet he performed; Miss Piggy’s hook was a “truck driver wanting to be a woman”. Oz has also stated that while Fozzie Bear is a two-dimensional character, and Animal has no dimensions, Miss Piggy is one of the few Muppet characters to be fully realized in three dimensions.
