The episode begins with Gumball and Darwin talking about why Principal Brown wants to see them. They decide to scream at him about how they are victims of corrupt society, before finding out that he only wanted them to show Sarah ( Dolly), an lemon custard ice cream cone new student, around the school. While introducing Sarah to several parts of the school, she compliments how "hardcore" Gumball and Darwin are. They briefly get overconfident over her statement, but soon they brush it off, suspecting somebody might overhear that and challenge them.
- Mr. Kreese (Semi-Antagonist until he's crying)
- This is apparently James Lamont's favorite episode.
- This is one of Ben Bocquelet's favorite episodes.
- James Garland Quintel the creator of the Regular Show hate that episode.
- This is Sarah's first major role.
- According to concept art, the humans in this episode were originally going to be animal characters.
- Gumball breaks the fourth wall by mentioning how the episode will end.
- This episode proves that humans do indeed exist in the Gumball universe.
- The human characters are designed like 70s/80s cartoon characters, primarily from shows by Filmation and the G.I Joe cartoon. Their mannerisms, on the other hand, are similar to those prevalent in vintage animes such as Speed Racer, along with the use of limited and choppy looking animation.
- Carlton calls Gumball and Darwin "Neo maxi zoom dweebies", a phrase that was used by John Bender in The Breakfast Club.
- There are multiple references to the movie The Karate Kid.
- The scene where Mr. Kreese orders Carlton to "break" Gumball is a parody of John Kreese instructing Bobby Brown to injure Daniel LaRusso's knee.
- The scene where Mr. Small tries to heal Gumball is a parody of the scene in which Mr. Miyagi tries to heal Daniel's leg before the final match.
- Gumball and Darwin gain respect from the crowd and their opponents after their loss, much like Daniel.
- In the closed captions, Mr. Kreese's name is misspelled Mr. Crease.
- Carlton has freckles for one scene, though this may have been on purpose to make fun of animation errors in cartoons from the 1980s.
- At one point, Jessica McDonald (while voicing Sarah) accidently starts slipping into her British accent.
