Darwin ends up in detention with Julius (the Bomb Kid), who decides to make Darwin his new target. However, it backfires when Darwin ruins his life.
Tropes:
- A Day in the Limelight: For Julius.
- Bread, Eggs, Milk, Squick: "Oh yeah, you hang out with the blue one with the big head who I turned inside out."
- Double-Meaning Title: Julius insists Darwin is a "sucker" he can con, but turns out to be the real sucker for Darwin's plan.
- Foreshadowing: When Julius asks how actually paying for a hundred gag pizzas to be delivered to the police (with his credit card!) qualifies as a prank, Darwin replies: "well, it's kind of a prank, just not on them." Julius fails to catch the hint. Afterwards, when Julius tells Darwin he's going to leave a surprise on the pool, Darwin briefly gains a look of apprehension before Julius clarifies he means with soap, which wouldn't have crossed his mind if he didn't actually know what Julius and his activities actually included.
- Ignored Epiphany: After discovering Darwin's ploy, Julius realizes beating and exploiting people eventually comes back to bite him—but since doing so taught him a valuable lesson, he concludes he should keep beating them to learn more lessons. He was joking.
- Karmic Trickster: Julius attempted to exploit Darwin's naivete for his own gains. In truth, Darwin was just playing dumb, and causing all his plans to backfire to punish him for all his deliquency.
- Literal-Minded: Darwin takes Julius's orders too literally, such as cleaning out a person's wallet (i.e. stealing the cash) involving him dusting it off. It's later revealed this was part of Darwin's ploy to purposefully mess with Julius.
- Noodle Incident: Several of Julius' extreme acts of bullying are mentioned, including pulling one guy's limbs off and turning Gumball inside out.
- Whatever he did to Darwin resulted in Darwin having "two weeks of physiotherapy and a permanently whistling nose."
- Obfuscating Stupidity: Darwin knew the entire time that Julius was trying to manipulate him.
- Pet the Dog: Julius and Darwin share a genuine Friendship Moment in the end.
