Gumball and Darwin deal with Sarah G. Latonote , whose creepy, fangirl ways begin to unnerve them.
- Animesque: The illustrations in Sarah's Fan Fic of Gumball and Darwin, which are spoofs of the bad anime-style drawings of typical fan fics.
- Bishie Sparkle: Sarah's drawings of Gumball and Darwin have sparkles and flowers surrounding them.
- Bowdlerise: Cartoon Network's Middle East/North Africa channel cuts out parts of Sarah's stalkerish song.
- By "No", I Mean "Yes":Gumball: Sarah, this whole... thing isn't working out.
Darwin: Yeah, it's not you, it's us.
Gumball: By which we mean it's you.
- The Cat Came Back: Sarah keeps showing up in front of Gumball and Darwin. At one point Gumball throws her away, and she falls on the next Sarah down the line.
- Comically Missing the Point: When Gumball and Darwin riff through Sarah's locker and discover she just wants Gumball and Darwin's friendship:Darwin: Are you thinking what I'm thinking?
Gumball: I know right? I'm definitely taller than you! And if my eyes were that close together, I'd be a cyclops!
- Continuity Cavalcade: Sarah's video includes pictures she took of Darwin and Gumball during events of previous episodes. Some of them are from before she transferred to Elmore Junior High and actually met them, implying she's been stalking them throughout the first two seasons:
- When Darwin was riding by on a broom in "The Colossus" to try and tame Hector, she took a picture.
- While Gumball was unconscious from numerous spider bites in "The Date", she got into his room by pretending to be a nurse.
- She was in the room while they were sleeping and connected to the dream machine in "The Dream".
- She has two pictures from "The Photo": one of the photos Mr. Small tried to take (unlike Mr. Small, Sarah managed to take a good version) and one of Darwin and Gumball after Darwin's "surgery" to Gumball's face.
- In the shot at the end of the song one of the pictures is a closeup on Darwin's face, which is from the deleted (in almost every country except the UK) shock collar scene in "The Skull".
- Contractual Genre Blindness: Darwin and Gumball go along with Sarah's fan fiction, even though it's ridiculous because they want to cheer her up and think it'll be fun.
- Conveniently Empty Building: The Rainbow Factory explodes for unspecified reasons. There's no mention of anyone dying, even though that's where Nicole works, so it can be assumed no one was inside at the time.
- False Reassurance:Gumball: I'm... not sure I'm comfortable with you following us.
Sarah: Don't worry! (whispers) You'll never see me.
- Funny Background Event: As Darwin looks at Sarah's drawings in her locker, Gumball observes one of Sarah's bad drawing of himself and Darwin. Sarah's drawing of Gumball depicts him as very short with close eyes, while Darwin is extremely tall. Gumball then compares their height and his eye placement while Darwin talks.
- Hypocritical Humor: Invoked when Sarah noisily eats ice cream from a cone before complaining out people who are loud when eat, but it's clearly her very bad attempt at launching a plot about Being Yourself.
- Left the Background Music On: Several scenes early on appear to have a Laugh Track which is actually being played by a recorder Sarah is hiding behind her back. She uses it throughout the episode to play sitcom music. Hilariously played with at the end of the episode when, during what is supposed to be a dramatic climax to the "battle" between Gumball and Darwin, Gumball is slowly shoving Darwin into a spinning fannote while Sarah's tape recorder is playing dramatic music. Gumball keeps shoving Darwin in but is shouting for Sarah to intervene, as per her story, but she won't because she can't get the tape player to stop playing the music. This forces Gumball to prolong the scene until he suddenly appears next to Sarah, grabs the recorder, and breaks it by throwing it off the building, causing the music to stop altogether—barring the music that she can sing.
- Medium Awareness: At the episode's end, Sarah begins singing the end credits tune, confusing Gumball.
- Noodle Incident: The episode begins with Gumball and Darwin failing to prevent the Rainbow Factory from exploding. The only details we're given is that it was somehow their fault in the first place.
- No Time to Explain: Gumball keeps citing a lack of time to explain all of his reckless behavior as he's running in the beginning, even though a lot of the stuff he's doing (like running over cars instead of the sidewalk, going through a topiary, or walking back to Sarah to push her) are clearly slowing him down.Gumball: No time to worry about collateral damage!
Darwin: I'm pretty sure that was just damage damage.
- Obsession Song: Sarah makes an incredibly upbeat song about how she's been stalking Darwin and Gumball with a video she sent to them.
- Oh Crap, There Are Fanfics of Us!: Darwin and Gumball finds Sarah's fan fic of them. Gumball is especially peeved that she draws him shorter than Darwin.
- Stalker Shrine: Sarah has one to Gumball and Darwin, including numerous pictures of them cut and pasted (on live action human bodies) to look they're hanging out with her.
- Perverted Sniffing: One shots of Sarah's video has her in Gumball's room, wearing his daytime clothes, putting the shirt he sleeps in over her face, and inhaling. It's accompanied by the line "I dressed in your clothes and breathed in your air."
- Reactive Continuous Scream: When Mr. Small touches Sarah while she's blending into a wall painting.
- Rhetorical Request Blunder: Some of Sarah's creepier behavior may have been a result of hearing Gumball describe her as "the insanely obsessive one" and taking this as an invitation.
- Saying Too Much: Sarah briefly tells Darwin and Gumball "I moved schools to be near you guys." in the cafeteria, although it goes without comment.
- Shirtless Scene: Part of Sarah's story had Gumball ripping off his shirt to reveal a wall of muscle. Real Gumball can't even tear his shirt, instead just taking it off to show he's exactly as scrawny as he looks.
- The Stoner: Implied when Gumball and Darwin asks Mr. Small why is he seeing the mural so idly, to which he responds by being happy that they can see it too.
- Stylistic Self-Parody: Gumball describes the effect of the water supply being contaminated by the Rainbow factory.They say our kids will look even weirder than we do!
- Take That, Audience!: Sarah's behavior is a pretty clear jab at the stereotypical fangirl. She's well-meaning, but she annoys Gumball and Darwin through her interference and even wrote adventures about the three of them, in the style of a stereotypical fanfic.
- Terrible Artist: Sarah's art is very poor. However, over the course of the show her style does improve.
- This Is the Part Where...:Gumball: Why would we want to see inside your locker?
Sarah: Because this is the part of the story where you realize maybe I do all this... because I'm lonely.
Gumball: No, Sarah. This is the part of the story where you realize there is no story. And you leave us alone.
- Wallpaper Camouflage: Sarah hides by blending in with a mural full of yellow circles and brown triangles.
- Wrong Genre Savvy: Sarah seems to think that she, Gumball and Darwin are in a sitcom, or some other kind of story than the correct genre.
