This is the first episode based on comics and superheroes. A comic appeared in "Nancy Clancy, Pet Psychic!" but it just was a regular object used by Jonathan and it doesn't have any other participation in that episode.
During the song, Rhonda and Wanda are wearing the same dresses they used in "Chez Nancy"; both times happened inside Nancy's Imagination.
The pink bear that falls while Nancy is singing, comes from another Disney Junior show named "Sofia the First", from the episode "Baileywick's Day Off"; it is a gift to all Amber's pink tea party attendants.
It is the first time that Lionel's mom has a mention in the show and the second that Lionel's room appears.
