- Ass Pull: The reveal that Kibidango is actually Peach's fiancé, Prince Haru.
- Broken Base: The ending. Some people don't mind that Peach was already engaged to Prince Haru, finding it to be a clever (if abrupt) subversion of the common gets the girl in the end trope. Others were absolutely furious since the revelation came out of nowhere, as well as Mario/Peach being near-canon in the gamesnote
- Die for Our Ship: Going by YouTube comments, Prince Haru comes under fire a lot for marrying Peach instead of her marrying Mario.
- Ear Worm: The song that plays over the opening credits.
- Ending Aversion: A lot of people were upset with the ending because Mario Did Not Get the Girl.
- Ensemble Dark Horse: The old lady that appears in the ending, due to her memetic "Aah!" shout and pose.
- Hilarious in Hindsight:
- In Mario's fight with Bowser, at one point, he grabs Bowser by the tail and throws him away. Guess what you have to do in Bowser's boss battles in Super Mario 64. Additionally, one scene in the film also involves Mario entering a sunken ship, just like in Super Mario World.
- This film used the idea that Bowser is in love with Peach years before Paper Mario and Super Paper Mario practically made it canon. What's more, a plot with Bowser kidnapping Peach with the intent to marry her would later be canon in the games (with a ring too big for Peach to properly wear no less), and like in the movie, she doesn't marry Bowser or Mario, though for much different reasons.
- Luigi in this film wears yellow and is obsessed with money, just like the later character Wario.
- Speaking of Wario......Princess Shokora from Wario Land 4 ended up in the exact same situation as Prince Haru: was turned into an animal by the main villain and it took pieces of jewelry to revert her back to normal, Haru's case being the necklaces and Shokora's being her crown, earings, necklace and bracelet. Unfortunately Shokora had the added case of being Dead All Along.
- The Toads in this film are all female, and 18 years later in Mario Kart: Double Dash!!, a female Toad named Toadette actually appears in the series proper.
- Older Than They Think: The anime uses a lot of elements that wouldn't be standardized in the games until the N64 and Gamecube eras. It's hard to tell if this is coincidental or if the anime influenced the games:
- In the games Bowser was a generic villain until the RPGs gave him more of a personality. This anime's portrayal of Bowser as Affably Evil is closer to his post-N64 game portrayal.
- In the games, Bowser having a Villainous Crush on Peach wouldn't be cemented until Paper Mario.
- While not as ditzy as usual, Peach's personality is more in-line with her game portrayal than the generic monarch she was at the time.
- What Do You Mean, It Wasn't Made on Drugs?: What do you expect from an anime based on Super Mario Bros.?
- WTH, Casting Agency?:
- Bowser, a character who we now associate with Scott Burns and Kenny James' badass Guttural Growler voice and an Expy of the Ox King, is here voiced by Akiko Wada, a famous Japanese female rhythm-and-blues singer.
- Peach is voiced by then-popular J-pop singer Mami Yamase. The fact that she's an idol and not an actress is apparent, and not helping is the fact that she makes the seemingly adult princess sound like a petulant, nasally ten year old (although this could be somewhat excused, as when the movie came out in 1985, Yamase was only 16 years old). note
