- Adaptation Displacement: Did you know that Mumfie was originally a series of books created by Katherine Tozer in the 1930's?
- Big-Lipped Alligator Moment: In-universe example in the episode "A Royal Mis-Understanding", when the Queen of Night is visited by people who want to marry her because Mumfie thought that losing your heart meant that you needed to love another person, but it turned out that the Queen actually lost her heart shaped locket. The narrator even lampshades that the Queen was unaware that she would be visited by people who wanted to marry her.
- Bizarro Episode: The majority of "Mumfie's Lost Button". First, Scarecrow tells Mumfie that he is scaring cows, then Mumfie loses his button, all of Mumfie's other jackets are missing, no buttons wind up matching the one missing on Mumfie's coat, nearly the entire cast (excluding a few characters) show up to offer Mumfie buttons with pictures relating to their hobbies that do not match the missing button, and Mumfie's jackets hanging on the clothesline being the wrong color as well as one jacket near his bed. Thankfully, this was All Just a Dream.
- Ensemble Dark Horse: Most fans seem to love Scarecrow more than any other character.
- Hilarious in Hindsight: The Queen of Night and The Queen of Light are sisters who are separated from each other. Do their descriptions, outfits and swapped hair colors remind you of two sisters from a popular Disney film?
- In "Cabin Fever", the narrator says "The coat fit Scarecrow like a glove, which made him wonder what a glove should fit like".
- Ho Yay: In "The Guest", Scarecrow blushes after hearing Mumfie play music off of his tissue box guitar he made.
- Memetic Mutation: Thanks to this show, many people now call people who worry "what-iffers". This may be thanks to Scarecrow being the most-liked character.
- Speaking of Scarecrow, the song he and Pinkey sang in the forest in Mumfie's Quest is also a meme.
- "Gotta Dance, Gotta Whistle, Gotta Sing" is also very popular.
- Periphery Demographic: Teenagers and adults watch this show too, as it's very well-written for a children's show, as well as the sexual jokes regarding Scarecrow.
- Viewer Gender Confusion: Mumfie is male but his pink clothes and unisex design confuse people.
- What Do You Mean, It's for Kids?: Let's see, we have a scarecrow who makes Freudian comments when he is asked to come somewhere, a scary villain who traps residents of an island, and plots and jokes that would go over the heads of toddler audiences.
