Muppet Babies mentioning names of performers, employees, different productions, and other pieces of inside information.
|In "What Do You Want to Be When You Grow Up?," footage of the red carpet crowd in The Muppets Go Hollywood is used as Baby Piggy and Baby Kermit imagine a famous lifestyle. The same footage re-appears in "Eight Flags Over the Nursery" as the babies ride through the Movie Studio section of Babyland.|
|In "Close Encounters of the Frog Kind," a brief shot from The Muppet Movie, of Kermit's legs exiting Bunsen's laboratory, is used during the Western scene between Baby Kermit and Baby Gonzo.|
|In "Once Upon an Egg Timer," when Baby Skeeter as a police officer is chasing after Baby Piggy for taking Baby Rowlf's voice, she calls on the radio for a roadblock on Henson and Frith Street.|

They turn out to be two Skeksis from The Dark Crystal (SkekAyuk and SkekEkt), who flee from them. This shot was originally used in The Dark Crystal, when the two Skeksis scream in horror and run from Kira.|
|"The Incredible Shrinking Weirdo" features a scene where a live-action adult Kermit interacts with an animated Baby Gonzo. A clip from The Muppet Show (Episode 223: John Cleese) was used, with Frank Welker dubbing new lines for Kermit and with Baby Gonzo matted into the scene. This fantasy sequence also featured a shot of the audience that was frequently used on The Muppet Show.|
|At the beginning of "This Little Piggy Went to Hollywood", the babies watch a TV special on Hollywood that showcased still photo of stars including Bert and Ernie, as well as a photo of Jim Henson.|
Later in the episode, a marquee reads "Henson's Biggest Little Pig."

Later, Gonzo and Fozzie are trying to find a missing penguin in the arctic. They decide to put his picture up on their blimp board, but Fozzie includes an image of Big Bird instead.
|"Nice to Have Gnome You" features clips from both Labyrinth and The Witches. Several of the Babies appear as characters from the former, intercut with footage of the actual Creatures, including Gonzo as Hoggle, Animal as Ludo, Scooter as The Worm, and Rowlf and Fozzie as The Four Guards.|

Sweetums and the Swedish Chef eventually became characters on the show. In Season 2, photos of Bean Bunny, Link Hogthrob, Dr. Julius Strangepork, Uncle Deadly, Sam Eagle and Bobo the Bear replaced previous images. In season 3, a picture of Beauregard replaced the picture of Sam.|
|The babies and chicks appear in what resembles the Muppet Show arches in their Muppet Babies: Show and Tell short "The Great Muppet (Short) Musical".|

|"Playground Pirates" includes a scene with a tiki head suspiciously resembling Sam the Eagle. The item reappears sporadically throughout the series, in episodes such as "My Brother Vinny" and "Animal and the Magic Mummy."
|"You Ought to Be in Pictures" features yet another statue of Blue Frackle during a scene parodying Ferris Bueller's Day Off. The statue can again be seen in the same spot in the museum, in the episode "Animal and the Magic Mummy."|
|An adult live-action Dr. Teeth appeared in "Muppet Rock" as the leader of Animal's favorite band. This marks the second time that the live-action character has had a guest spot on the Muppet Babies franchise; he was previously featured on the original Muppet Babies episode "Muppets Not Included." Muppet performer Bill Barretta, who performed Dr. Teeth in the appearance, admits that he doesn't quite understand how it works if the other Muppets are babies but he's an adult.|
|Baby Fozzie appears behind a cardboard cutout of Lew Zealand in "No Laughing Matter". In the same manner, he also gives Miss Nanny a face for the first time since the character's introduction.

|"Wocka by Fozzie" shows a flashback, during which Miss Nanny is seen with a slightly smaller Baby Fozzie, donning an approximation of her classic, striped tights that she wore on the original Muppet Babies series from 1984. For the rest of the episode, she is seen wearing her typically themed tights.|
|"Wocka by Fozzie" also shows a silhouette of Baby Fozzie imagining himself growing up while riding a bicycle (play animation).|
|Further, "Wocka by Fozzie" has Ma Bear appearing in the imagined nighttime sky to both Baby Fozzie and Baby Kermit.|
|Jim from The Country Trio can be seen in the Muppet Theatre audience in "Win a Twin". The character can later be spotted again, as part of a crowd of parade onlookers in "Friend-a-versary."|
|In a visual reference to a scene from The Muppet Movie, a giant Animal appears in Fozzie, Gonzo, and Rizzo's imagination in "Oh Brother."|

Kazagger's painting even has a photo of himself and Gonzo from one of the Good Morning America sketches from 1992. The painting of Rowlf briefly reappears in the episode "The Copy Cub."|
|In "The Copy Cub," Fozzie and Rozzie (as well as two identical copies) appear at the characters' imagined Muppet Theatre to perform a comedy act in front of a backdrop reminiscent of adult Fozzie's comedy act.|
|While technically a Muppet film inside joke, this is the first inside joke to ever involve the Muppet Babies:
In The Muppets Take Manhattan during the song "I'm Gonna Always Love You," Baby Rowlf plays doctor with a plush doll of Big Bird. For the scene, a rubber duckie can be seen sitting on a shelf behind him.
|After first appearing in mobile puppet form in A Muppet Family Christmas, this iteration of Baby Animal made another brief appearance on the Lipton "Be More Tea" commercials, otherwise surrounded by a frog, a pig, and an entire world's population of adult Animals.|
|While technically a Muppet TV series inside joke, the Muppet Babies were yet again referenced in the adult Muppets' world:
Beginning with the Muppets Now episode "Due Date," whilst sharing his computer screen, adult Scooter's desktop image can be glimpsed behind an unorganized slew of files and folders, revealing a (new) baby photo of his younger self.
