Skeeter is a female athletic Muppet who originated from the animated series Muppet Babies as Scooter's tomboyish twin sister. Unlike the other babies, Skeeter was created specifically for Muppet Babies as an addition for the show's female figure Miss Piggy. With Miss Piggy being the only major female character in The Muppet Show cast, Skeeter was introduced to balance Piggy's ultra-feminine role.
Like many female Muppets, Skeeter was performed by male actors. Howie Mandel voiced the character for the first two seasons of Muppet Babies, after which Frank Welker took over the role. In the reboot, she is voiced by Cree Summer, making it the first time she was ever voiced by a female.
Skeeter is energetic, gutsy, and spirited but, at times, can be a bit of a show-off. Skeeter and her brother Scooter would occasionally show signs of sibling rivalry in the nursery, with Skeeter often calling her brother a "nerd." While Skeeter often expressed interest in being an athlete or gymnast, her brother was more interested in computers and books.
Despite her tomboyishnesss, she had a rivalry with Miss Piggy, where they would often fight for the feminine roles.
After Muppet Babies, Skeeter made few appearances in Muppet-related media. In MuppetZine issue 3 (1993), Muppet Babies storyboard director Scott Shaw wrote:
- "As for the adult Skeeter, Henson Associates art director Michael Frith once explained that she's now a famous explorer, never seen again after an expedition to the jungles of the Amazon!"
When asked in 2009, "Whatever happened to Skeeter?", Muppet writer Jim Lewis said:
- "Ahh, Skeeter. I wasn't there for the creation of the "Muppet Babies" animated series, but I suspect she was added to the show so there'd be another (dare I say, more balanced than Baby Piggy) female character on a show aimed at kids. We threw around various bizarre scenarios about what happened to Skeeter after "Muppet Babies," but none of these were ever confirmed. Frankly, I suggest contacting the Federal Witness Protection Program for more info. Let us know what you find out." 
Skeeter appears in The Muppet Show Comic Book during the "Family Reunion" story arc, written by Roger Langridge and illustrated by Amy Mebberson. Initially, the dialogue throughout the four-part story avoids using her name. Langridge cites that an arrangement was made between Boom! Studios and Disney, and the character is referred to as "Scooter's sister" in the story. (She finally signs a letter at the end of the story, as "Skeeter.") Much like her role on Muppet Babies, she has a complicated relationship with Miss Piggy; in one moment she appears to extend an olive branch, but in the same beat, plants an immature sign on Piggy's back. During her time at the Muppet Theater, she affectionately refers to Scooter as a nerd, manipulates Andy and Randy Pig as pawns in a practical joke on Piggy, takes a misplaced interest in Robin's well-being, and poses as Fozzie's girlfriend. As the story comes to a close, Skeeter heads back to college to finish her degree in archaeology, while also revealing that she is Agent X, an assistant for world-famous detective Wormwood Soames.
In a recent interview with ToughPigs.com, Langridge mentioned that he was talking about having Skeeter return for one of the story arcs.
In 2011, Amy Mebberson stated that she is "determined to re-establish Skeeter as [a member of the Muppet] canon if it kills me."
