Phineas and Ferb head to the Tri-State Area's annual sci-fi and fantasy convention to meet their hero, special effects guru Clive Addison. Their plan gets sidetracked when they're swept into a duel between the fantasy fans and the sci-fi geeks. Meanwhile, Candace tries to keep secret that she's a fan of Ducky Momo, another convention staple. Across the convention hall, Dr. Doofenshmirtz has taken television executive Jeff McGarland hostage so he can pitch him a show he's developed, "Doof 'n' Puss."
Tropes:
- Acquired Error at the Printer: The rare Ducky Momo collector's plate reads "I hate people!", as a result of accidentally printing the wrong saying.
- Actor Allusion: Doofenshmirtz (played by series co-creator Dan Povenmire) attempts to pitch his show to Jeff McGarland (played by Seth MacFarlane). Dan Povenmire himself used to work with MacFarlane on Family Guy.
- All for Nothing: Candace finally buys a rare piece of Ducky Momo merchandise, a commemorative plate with the wrong saying printed ("I hate people"), but once she sees the monster her brothers created, she breaks it. But at least she got some acceptance from Jeremy when she outs herself as a closeted Momo fan to him.
- Argument of Contradictions: Finkies! Speckies! Finkies! Speckies! Finkies! Speckies!
- Battle Theme Music: "Our Movie's Better Than Yours".
- Blatant Lies: Candace tells her mother that she is going to Stacy's and the big bag she is carrying has smaller bags. (Supposedly, it's actually her Ducky Momo costume.) She also tells Jeremy she's hanging with Stacy and tells Stacy she's hanging with Jeremy.
- Borrowed Catchphrase: After rejecting the suggestion of "giving the platypus a girlfriend", Doof borrows Candace's catchphrase, "My artistic integrity and I are out! PEACE!"
- The Cameo: The Talking Zebra appears briefly in the simulation sequence at the beginning, holding a picture of Candace emulating the Barack Obama "HOPE" mural.Talking Kevin: I voted for you, Kevin.
- Catchphrase Interruptus: When Phineas and Ferb arrive at the convention, Phineas begins to say, "Hey!", but then we cut to a sepia-toned drawing of Perry and we hear...Doofenshmirtz: "Where's Perry" is written on this wanted poster, hanging on a tree. And we see this little hand reach up and tear the poster down and the music kicks in and all, "Chicka, chicka, chow, chicka, chow, chow, chicka, chicka, chicka, chicka, chow," and the opening credits start, like on one of those cool 80's TV shows with a voice over. You know...
- Celebratory Body Tossing: After Candace (dressed as Ducky Momo) "defeats" the monster, all the convention goers toss her into the air, celebrating how "Ducky Momo" saved them from the monster. Subverted when Candace reveals herself to be the one wearing the Ducky Momo suit, causing the nerds to put her back down and laugh at her for liking such a childish property.
- Closet Geek: Candace is revealed to be one for a young children's cartoon show titled "Ducky Momo"; she attends the annual convention looking for rare Ducky Momo merchandise wearing a full Ducky Momo costume, so that no one would recognize her.
- Description Cut: Baljeet, a Speckie, asks Phineas if he has even met the Finkies leader.Buford: I'm sure you're wondering why I, Buford, have taken a leadership role in such a geek-centered enterprise. Well, take a look around! This place is crawlin' with nerds! I'm like a kid in a candy store! Plus, I relate to the character of Odoff Underhump and his complex emotional inner journey.
- Dramatically Missing the Point:
- When Phineas and Ferb are about to greet Clive Addison and show their special effect demo, they are interrupted by Irving and Albert, who inadvertently distract them long enough for Clive to head off, causing Phineas to sigh in disappointment. Irving takes this to mean that Phineas (who is dressed as a "Space Adventures" captain) is upset that Ferb (dressed as an Elf from "Stumbleberry Finkbat") is picking fantasy over sci-fi.
- Clive reveals to Phineas and Ferb that he became a special-effect producer for "Space Adventures" and "Stumbleberry Finkbat" to bring people together. Instead, the respective fans of both films have a strong Fandom Rivalry.
- Enemy Mine: Invoked by Phineas, Ferb, and Clive by creating a giant monster with special effects to make both sides work together.
- Even Nerds Have Standards: Even before the two fandoms called a peace, they both share a disdain for the children's show Ducky Momo, much to Candace's shame.
- Executive Meddling: In-Universe. The producer Doofenshmirtz pitched his show to agreed (after being held hostage) to greenlight his idea, but asks that the platypus should get a girlfriend. Doofenshmirtz is furious at the idea and walks away, saying he refuses to be a Sell-Out. The show was made anyway, and Doof lampshades at the end that they were probably right. It was also a production in-joke, as "give the platypus a girlfriend" was an actual suggestion given by Disney when Phineas and Ferb was first pitched.
- Expository Theme Tune: The theme for Doof 'n' Puss is presented in the style of action shows from the 1980s, such as The A-Team. See Wunza Plot.
-
Fandom Nod: Candace being a closeted fan of Ducky Momo can be seen as an acknowledgement of the adults who enjoy Phineas and Ferb. - Fandom Rivalry: In-Universe between the fans of "Space Adventures" and "Stumbleberry Finkbat." This is against the wishes of their producer Clive.

After they've been found out, Perry hops out of the box, his two halves actually separated but himself still alive.
- Show Within a Show:
- The film franchises, sci-fi oriented "Space Adventures" and fantasy oriented "Stumbleberry Finkbat", are a source of conflict between the two fandoms.
- There's also "Ducky Momo", a child-aimed program that Candace enjoys.
- A variant is the show pitch Doofenshmirtz created to rally his own fandom, "Doof 'n' Puss".

- Stylistic Suck: Doof 'n' Puss may look cool with its sepia-toned picture and well-performed fight sequences, but it still doesn't cover the fact that the concept and writing is über-ridiculous.

Together with the aid of R.I.C.K, their super-crimefighting-high tech-talking rickshaw, they'll bring hope, justice, and varying degrees of aquaticness to a Tri-State Area in peril!
- You and What Army?: Buford asks this after Baljeet's Bait-and-Switch peace accord turns out to be a declaration of war, but Baljeet says that doesn't make sense.
