The main plot line of the story arc has the Muppets reunited with Scooter's sister, Skeeter, making a rare appearance in adult form. Although Skeeter is present in all four issues, each issue has focus on a different Muppet relative (Skeeter in part 1, Andy and Randy Pig in part 2, Robin the Frog in part 3, and Ma Bear in part 4). With the exception of Robin (whose own story ends with an appearance by an unknown Muppet relative), each relative was not a major character on The Muppet Show (Ma Bear appeared in two episodes of the series).
