While the boys create a giant jukebox, Candace meets the princess of Drusselstein who looks just like her and they switch places for a day, but the ongoing antics of her brothers prevent her from enjoying it, even for a while. Meanwhile, Doofenshmirtz plots to ruin Roger's unveiling of the Danville Opera House with his Claw-inator.
Tropes:
- Anachronism Stew: Lawrence gives a dramatic buildup describing the anticipation of selecting a song on a 1950s jukebox and waiting for it to start. That buildup is all undone by a song with Liverpudlian voices singing "I'm a jammie lad / I've got a smashing bird / And my trousers are mobbed and groovy".Lawrence: Hmm... and this leads directly to the 1960s. Oh, well, time to get this beaut to the antique shop. Ta, boys!
- Are You Pondering What I'm Pondering?: Candace tells Princess Baldegunde that she has to do everything for herself, and Baldegunde says that she can't do anything for herself. Both have an "A-ha!" moment, after which Candace says, "Let's go to the laundromat and fill the dryers with cheese!"
- Bait-and-Switch: "Wow, I've been given all this power and how I've chosen to use it is to run through gold coins barefoot. (Beat) I'm a genius!"
- Bread, Eggs, Breaded Eggs: Monogram is not certain what Doof's plan is, only that it involves a princess, an opera house, claw machines, and stuffed animals. He tells Agent P to "do the math", and if you put them together, you get a...Major Monogram: Claw-Princess-Animal, uh, Stuffed-Claw-House—
Carl: Uh... Ooh! Ooh! Ooh! Ooh! Or a...or a, Singing Animal Claw... Clawpera House... Stuffy Stuffness!
Major Monogram: (simultaneously) A Singing Claw... Clawing... Clawing House with a— It's terrifying. - Breaking the Fourth Wall: When it turns out that Princess Baldegunde does look like Candace:Monogram: Oh, wow! What are the odds?
Carl: Well, it is a cartoon sir.
Monogram: What did I tell you about breaking the fourth wall, Carl?
Carl: Sorry, sir. - Continuity Nod: Jeremy's band performs "Do-Nothing Day" from "The Best Lazy Day Ever".
- Department of Redundancy Department: "At 2:00, you have gala ball. At 2:30, you have premiere gala. At 3:00, you have Gala-Gala Oxen Free."
- Funetik Aksent: Princess Baldegunde speaks with an Eastern European accent, which is evident when she refers to Candace's brothers as "Pinnayus and Firb". Ferb and Buford seem to be the only one who notice that "Candace" suddenly gained "an upperclass Drusselsteinian accent".
- Identical Stranger: Princess Baldegunde of Drusselstein, who looks and sounds exactly like Candace but with a Drusselsteinian speech pattern.
- Leaning on the Fourth Wall: Baldegunde's assistant tells her she has eleven minutes until her gala gathering.
- Mad Libs Catchphrase: "Ah, Perry the Platypus. It's ironic that you look like a stuffed animal in one of those claw machine games. And by 'ironic'..." (traps Perry in crane machine) "...I mean, 'totally flat out ronic'."
- Prince and Pauper: Candace pretends to be the princess to get a taste of royalty, and the princess pretends to be her to have fun for a change.
- Screw This, I'm Outta Here:
- Buford, after he sees Princess Baldegunde pretending to be Candace.
- Candace, after Princess Baldegunde calls her and asks about Jeremy.note
Candace: That's enough "Princess" for today, I want my life back! - Title Drop: The phrase "make play" is dropped multiple times by Princess Baldegunde, who thinks that Phineas and Ferb are just messing around in the backyard.
- Twin Switch: What Candace and the princess pull for the episode.
- Violently Protective Girlfriend: When Baldegunde calls Candace to ask the pronunciation of "Cute Blonde Boy with Guitar".Candace: What cute blonde boy?Baldegunde: The one with band. Is it "Jer-EH-mee" or "Germ-EE"?Candace: It's pronounced, "Stay away from him!"
