Miss Nanny's socks match the theme of the episode.
Around the Nursey are pictures and posters of other Muppets; Mahna Mahna and the Snowths, Pepe, the Swedish Chef, Lew Zealand, Sweetums, Dr. Teeth and The Electric Mayham, Scooter and Skeeter, plus others. Many of them in their "baby" form.
Skeeter was never made into a real-life Muppet. She only appears in the original Muppet Babies (1984) series.
On October 23, 2020, it was reported original Muppet Babies (1984) writer Jeffrey Scott is suing The Walt Disney Company for using ideas that originated in the 1984 series without permission or credit. Scott also stated that he presented ideas and concepts to Disney in 2016 that were used without his permission.
Just like in the original Muppet Babies Nanny's face is never seen.
