- Actor Allusion:
- Art Shift: Bunsen marks a notable change in Butch Hartman's art style, which is usually more angular in nature. This show is also Hartman's first cartoon to be animated in Adobe Flash, whereas his previous shows were animated traditionally.
- Celebrity Voice Actor: We have Jeremy Rowley and Ben Giroux as Bunsen and Mikey.
- Crossdressing Voices:
- This was going to be the case with Mikey, as mentioned under What Could Have Been, but he ended up being voiced by the male Ben Giroux.
- It is however played straight with a young goth boy, who's voiced by Jennifer Hale.
- Dawson Casting: Once again, we have teen and preteen characters voiced by adults
- Dueling Shows: With Disney Junior's Vampirina, another show about a supernatural somebody trying to fit into human society.
- Screwed by the Network: When the show premiered in late February to March, it had less reruns, can only be seen on Saturdays where new episodes would only air on that day, until on June 2017, most of the reruns had moved to Nicktoons, while the former channel will only exclusively air new episodes only on Saturday and later moved reruns to 4AM.
- Nickelodeon only aired the show for TEN months, the show is moving to Nicktoons in December 2017.
- There have multiple occasions the show has had episodes pulled on Nickelodeon including the Christmas special and many premieres over the summer.
- Also another final insult came when it revealed that Butch Hartman explained that the show was meant to last for only one season, while seen as hes leaving Nickelodeon after spending 20 years working with them.
- The finale had aired in between 10PM and at 4:30 AM with no promotion or any indication for anyone to know the time to see the episode. It was almost as if Nick was trying to bury the show completely after Hartman had left the network completely.
- What Could Have Been:
- Butch Hartman originally conceived the premise for a picture book, until a higher-up at Nickelodeon suggested pitching it as a cartoon.
- In early artwork and footage for the series, Mikey had a different shirt, blue eyes, and was played by Maile Flanagan, the voice of Naruto Uzumaki (yes, that Naruto Uzumaki).
