  • Continuity Nod: Shego & Vanessa discuss several old plans of both Drakken & Doof's from several episodes to prove which of them has the stupider ideas.
  • Didn't Think This Through: If you put a naked mole rat in straps meant for a human, of course they'll slip out. Doof himself lampshades this when it does.
  • Don't Explain the Joke: After Doofenshmirtz straps Perry to a table in front of a laser, he tells him to "prepare for a slice," before explaining that he means the laser will slice him to pieces.
  • Free-Range Children: Phineas, Ferb, & Isabella pretty much just walk down to Doofenshmirtz Evil Incorporated with no one noticing. Justified in that Candace wasn't really paying attention.
  • Incredibly Lame Pun: Most of the titles of the stories, as well as the respective chapters.
  • Inescapable Net: Averted & Played for Laughs; Phineas & Ferb throw a net on Drakken and he orders Shego to help him, until she points out it's just a net, allowing him to easily escape.
  • Innocent Innuendo: Kim & Ron's actions at the beginning.
  • Insistent Terminology: During the story, Shego grabs Isabella and threatens to "fry the Girl Scout" unless Kim & Ron surrender. Isabella then angrily reminds her captor that she's a Fireside Girl, not a Girl Scout.

  • Loophole Abuse: As Candace notes, Kim told her not to touch anything in the car, she never said she couldn't drive it.
  • Oh, Crap!: Candace realizing that the Sloth, (which she "borrowed") is now driving itself back to her house.

  • Verbal Backspace: As they're escaping from the cage, Isabella tells Phineas that "if we don't get out of this, I just want to say... I love you." Phineas doesn't hear her due to picking the lock, and when he asks what she said, she replies with "I love glue."

  • Brainwashed and Crazy: Perry ends up like this, compliments of the two docs.
  • Curb-Stomp Battle: Kim vs. Perry Perry wins the first time, and nearly beats her the second time until his brainwashing is undone.
  • A Day in the Limelight: Candace appears in this story much more than she did in the original, and is even integral to the plot.
  • Demoted to Extra: Isabella isn't as prominent in this story as she was in the previous one. Although, that's because most of the story takes place in Middleton, and she stayed behind in Danville to watch Perry.
  • Good Angel, Bad Angel: Candace sports these when deciding whether to break into Kim's closet; even her angel suggests she should.
  • I'm Standing Right Here: As Candance badmouths her brothers over the phone, Phineas comments that he can hear everything she's saying.

  • Portmanteau Couple Name: Ron attempts to come up with one for him and Kim, but finds neither "Rim" or "Poppable" to be all that great.
  • "The Reason You Suck" Speech: Kim gives one to Candace after getting fed up with her actions, basically telling her to quit copying her and get her own life.
  • Strange Minds Think Alike: During the story, Kim, Ron & Candace are shown watching Ballroom with the B-List and commenting on it. Moments later, Doof & Drakken are shown doing the same.
  • Suspiciously Specific Denial: Isabella did most certainly not lose Perry and he is definitely in her house and not lost.
  • Talk to the Fist: Perry delivers this to Doof at the end.
  • What Happened to the Mouse?: Shego disappears near the end of the story (although Drakken said she was taking her vacation). The real reason is because the author figured she'd easily defeat Kim and supersuit-enhanced Candace and wanted to give them a fair fight.

  • Running Gag: When Riley sarcastically tells Dick that Kim is a crimefighter/pop star, he keeps making references to said career throughout the story.
  • Shout-Out: After meeting CAR, Ron comments that he's like that talking car on that show and asks him to say "I've got a bad feeling about this Michael."
  • Tempting Fate: A Cutaway Gag shows the developments of one of Henchco's newest weapons a brainwashing helmet with one of the developers telling Jack Hench it works perfectly... although extreme feelings of love from a relative are strong enough to disable its' effects.

  • Call-Back: In the previous story, Kim told Ron she didn't want him eating Bueno Nacho in the car because it was hard to clean out. In this story, she lets him have a chimerito, because, since they're going on vacation, she can relax the rules a little.
    • When Kim finds Drakken on the island, she mentions she's there to get a vacation from her last two adventures, including his "Take Over the World through the Internet" scheme from "Fan-tastic Voyage."
  • Co-Dragons: Myron for Dementor and the Leroys for Hämsterviel
  • Conservation of Ninjutsu: Averted, the Leroy's often attack Stitch en masse.
  • Curb-Stomp Battle: Ace, the only not-evil of Jumba's experiments (and therefore, immune to Hämsterviel's beam) easily defeats a handful of the rogue experiments until Shortstuff manages to backhand him.
    • Also, even with Drakken & Shego's help, the heroes don't fare so well either.
  • Egopolis: Dementor plans to rename the taken over island "Dementoria" until Hämsterviel convinces him to come up with something with both of their names.
  • Enemy Mine: Kim is forced to team with Drakken & Shego, who were taking a vacation on the island, to stop the rogue aliens. Naturally, Kim & Shego aren't too happy about that.

  • Forceful Kiss / "Shut Up" Kiss: Kim gives Ron a combo of both of these near the end after he won't stop babbling.
  • Hoist by Their Own Petard: Pointed out by Jumba, that it's ironic that Hämsterviel & Dementor are defeated by the very experiments they intended to use to conquer the island.
  • I Have to Go Iron My Dog: Ron gets out of eating Pleakley's pancakes by saying "Me and Rufus have...some stuff to do."
  • Insistent Terminology: The Leroys are not Hämsterviel's pets, they are his "henchmen."
  • Lethal Chef: Pleakly, as per usual; when making pancakes for breakfast, he said that he didn't have all the ingredients but he "used some substitutions."
  • Nice Job Breaking It, Hero: If Kim had stayed around to ensure that the authorities picked up Dementor, or even went after him, he wouldn't have escaped and hooked up with Hämsterviel.
  • Noodle Incident: What happened when Ron tried surfing; Word of God is that the author was originally going to write that scene, but then decided it would be funnier if it was left to the reader's imagination.
    • Also, how Ron knows that nacho cheese & puke are hard to clean.
    • Whatever Lilo & Stitch did that Jumba won't allow them to use his inventions anymore. They assumed a heat ray would generate heat and were just trying to warm up.
  • Police Are Useless: Dementor mentions he's no longer in jail because the jail in Pleasant Hills was "run by incompetents"; Wade later learns that the reason he didn't know Dementor was out was because they were so embarrassed he escaped, they lied and said he was still there.
  • Post-Kiss Catatonia: The result of the Forceful Kiss mentioned above.
  • Right Behind Me: While waiting for Kim, Ron tells Lilo that she takes forever to get ready and that you never see pictures of her in the morning "because they are not flattering"; he then learns that Kim heard everything he said from the doorway.

  • Shout-Out: After Kim tells Wade that Dementor was planning to block out the sun, Wade questions "didn't an old guy from a TV show try the same thing?".
    • When Ron is talking about his bad surfing experience, he comments that he got a starfish in his swimsuit and they're not all silly and funny like on TV.
    • "This isn't good, this is super bad! Unlike the movie, which was super good!"

  • Noodle Incident: Whatever happened when Heidi interviewed Principal Slimovitz. It was apparently her worst show ever.
  • Official Couple: Randy & Theresa by the end. Though the writer rarely strays from the canon of the shows, he decided to go for it, since most people ship them anyway.
