Skeeter died tragically between the events of Muppet Babies and The Muppet Show.
Nanny is Angelina Jolie.The Muppet Babies are all the kids she's adopted. She retired from acting and moved to the suburbs.
Disney is currently plotting to buy every single franchise/company that owns the copyright to all stock footage used in this show so they can make a fortune form the fans who have been pining for a dvd release for years.They're off to a great start; they've already got the biggest one — Star Wars — down.
Skeeter is alive and well.Ozzy Osborne had one daughter who chose not to be on the famous "Osburnes" reality show, wanting to maintain her privacy. When the Muppets grew up, Skeeter made the same decision. She decided she was done with the spotlight, and went on to go to college, get a regular job, marry and have a family. Even her more famous brother Scooter is rather low-profile compared to the other famous Muppets; he's never had a lead role in a movie, was never more than a side-character, and works as a back-stage techie. It's no surprise his sister would choose to leave show-biz altogether. He probably still calls Skeeter every week and sees her on holidays.
Gonzo's story in "Fozzie's Family Tree" were inspired by real, but vague, memories."Muppets from Space" confirmed Gonzo's alien origins. This makes sense, considering that baby Gonzo was already claiming alien heritage. Where it gets confusing is that the adult Gonzo seemed almost as surprised as everyone else to learn of his heritage. The explanation? Gonzo never "knew" he was an alien...but he fantasied about it. And those fantasies were based off of small, foggy memories from his earliest years. Throughout the Muppet show and the movies, hints of Gonzo's being an alien continued to be dropped, so his "family tree" story was only the first of many nods. Oh, and the "decolonization" of "Muppets from Space?" We saw what happens when the government finds out about an alien on Earth. Obviously Kermit convinced Gonzo to keep mum about his origins, for his own protection.
