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.
Just like in the original Muppet Babies Nanny's face is never seen.
Tony winner Elise Goldsberry, who played Angelica in Hamilton, sings the Muppet Babies theme song.
