Kermit and Miss Piggy occasionally perform musical numbers together. Some of their duets include " I Won't Dance", " Ukulele Lady", " Waiting at the Church", " The First Time It Happens", and " Love Led Us Here". Because Frank Oz was busy with other projects and not on the set very often, Miss Piggy was puppeteered by Kevin Clash in Muppet Treasure Island and Peter Linz in Muppets from Space, with Oz dubbing the voice in later.

In the Kaye Ballard episode of The Muppet Show, it has been proven that Miss Piggy can play a few instruments such as the trumpet and kazoo.In addition to her many real world endorsements and licensing, Miss Piggy has occasionally created her own brands and products, such as Piggy Water in the 2015 series The Muppets (" Going, Going, Gonzo.") On her August 2, 2007 guest appearance on The Late Late Show, Piggy stated that her first name is actually "Miss". This fact was also mentioned in the inside cover for The Kermit and Piggy Story.

The character was referred to as "Piggy Lee" in one Muppet Show episode, episode 106. She also uses that name in the 1977 Muppet Show Annual released in the U.K. Miss Piggy considers herself a dramatic actress and a great singer, but she has other talents, too (besides karate).

Miss Piggy's distinctive personality has been seen in a few other Muppet characters before the famous sow's debut. For instance, this personality and voice can be seen (and heard) in the Sesame Street versions of Little Miss Muffet and Snow White, both performed by Frank Oz. Pointed out by Rowlf in The Muppets: A Celebration of 30 Years and Kermit in A Muppet Family Christmas, no one can make an entrance like Piggy. Miss Piggy starred in two regular Muppet Show sketches -- " Veterinarian's Hospital", as the ravishing Nurse Piggy, and " Pigs in Space", as the enchanting First Mate Piggy.

The correspondence course wasn't Piggy's only training. In an interview with Hitfix, she stated that she learned at Master Chang's Charm School and Karate Dojo; it was also a Chinese restaurant that Kermit used to go to. Eventually in the films, Kermit started returning her affections and (unwittingly) married her in The Muppets Take Manhattan—although subsequent events suggest that it was only their characters in the movie that married and that their relationship is really the same as ever.we would anticipate coming up with new personalities which would have much of the same kind of appeal as a Kermit, Fozzie or Gonzo. We will not create anybody with Miss Piggy's kind of appeal- nobody should try. ” She wants everyone to treat her like a lady, and if they don't, she'll cut them in half." -- Frank Oz in Time Magazine, Dec. 25, 1978. A month before the debut of their 2015 ABC series, The Muppets, Miss Piggy and Kermit formally announced that they were breaking up. Piggy said in a statement that “Dating moi is like flying close too the sun. It was inevitable that Kermit would drop down to the ground while I stayed in the heavens.” while also concluding it was a mutual agreement. Kermit however countered “After careful thought, thoughtful consideration and considerable squabbling, Miss Piggy made the difficult decision to terminate our romantic relationship.” It was specified, however, that they will continue to work together.
