Skeeter is the only one of the main baby characters who was never made in an "adult" puppet form for The Muppets' standard appearances. She is unique to this animated version, and was created because the producers wanted another female character in the show. She was voiced by men (Howie Mandel and Frank Welker), just like most of the adult female puppet characters.
Are you the Great Gurgle?
Great Gurgle: No, I'm Snow White.
Fozzie: Snow White? I thought she was shorter.
After the credits of each episode, Gonzo and Animal would do something that matched that episode's theme and it would end with Animal saying "Go bye bye!"
