Little Muppet Monsters Jim Henson ' s Little Muppet Monsters was a 1985 Saturday morning TV show which aired only three episodes on CBS , with as many as 15 episodes going unaired . The first season of " Muppet Babies " did very well in the ratings , so CBS decided to expand the series from half an hour to an hour - long block , pairing " Muppet Babies " with " Little Muppet Monsters " to make an hour - long package ( with its own intro ) called " Muppets , Babies and Monsters " . The show was anchored by three young Muppet monsters , Tug , Boo , and Molly , living with Muppet rats , penguins and other characters . " Muppet Show " characters such as Scooter , Kermit , Janice , and Floyd appeared in cameos . The Electric Mayhem were featured in both intros watching the show on television , as they excitedly bounced about on a living room sofa . Miss Piggy also appears in the intro . Muppet segments included " Fozzie ' s Comedy Corner , " with Fozzie discussing issues related to old jokes , illustrated through animation of a baby chicken , and Gonzo presenting a cavalcade of weirdness , using silent film footage . Each episode also featured an original Muppet song . Recurring animated segments included " Pigs in Space , " " Kermit the Frog , Private Eye " ( as introduced by the puppet Kermit , with Fozzie and Miss Piggy ) , " Muppet Sports Shorts " starring Animal , and Muppet Labs with Bunsen and Beaker . Gonzo would also have appeared in animated segments . The show was split at about 50 % animation and 50 % puppetry , with appearances by Kermit , Fozzie , Gonzo and others being shot in London , and the rest in New York . The puppet segments from three unaired episodes were leaked to the internet in 2015 . Storyboard director Scott Shaw discussed the show in MuppetZine issue # 3 ( Winter 1993 ) : A major factor that contributed to the show ' s cancellation was the fact that Marvel Productions had trouble delivering the animation on time . Marvel " blew it , " as series writer and puppeteer Kathryn Mullen remembered in 2013 , and there were no completed shows to fill the extra half hour : " So they [ CBS ] put another " Muppet Babies " on , two episodes back - to - back , the viewership shot up , and they said , ' Forget " Little Muppet Monsters " . ' " As for the unaired episodes , " We never finished them . The puppet wrap - arounds were done , but they never put the animation in . " Even after " Little Muppet Monsters " was cancelled , an instrumental version of its opening theme was used in the " Muppet Babies " end credits from 1985 onward . Merchandise . Henson archivist Karen Falk spoke about the series ' licensing campaign : According to the Henson newsletter , Toy Fair 1986 would have seen the launch of plush by Hasbro , board games and puzzles by Milton Bradley , puzzles by Playskool , costumes by Ben Cooper , stickers by Diamond Toy , balloons by Balloon Concepts , boys and girls sportwear by Allison Mfg . , greeting cards by Hallmark , belts by Lee Belts , pajamas by PCA Apparel , and party supplies and gift wrap by Beach Producers .
