The best way to defeat a platypus is to become a platypus!

— Heinz Doofenshmirtz

Change is afoot when Candace accidentally liquefies herself by coming in contact with Phineas and Ferb’s device that turns solids into liquids. Meanwhile, Dr. Doofenshmirtz turns himself into a platypus to defeat Perry in battle, but finds it’s harder than he ever imagined.

Episode Summary

The episode opens with Phineas, Ferb, and their friends getting "Exotic and Unusual Smoothies". Buford then comments that the smoothies are not as "exotic and unusual" as they could be, while Isabella agrees but says Phineas and Ferb could do better.

Perry enters his lair through a lengthy tricycle ride, and then Major Monogram tells him that Carl has stained the Agency's favorite couch. Carl defends himself by saying it was Agent M. Monogram then tells Perry what Doofenshmirtz has been up to. Doofenshmirtz was seen at the library checking out books on Eastern Australia and Hydrostatic Cell Fusion. He sends Perry off to find out why.

In their backyard, Phineas and Ferb present their latest invention, The State-of-the-Matter Transfer Device, which can turn any solid into a liquid, so they can enjoy all sorts of new and unusual flavors. Buford then tries it on a chicken. He then drinks the "liquid poultry", which he says, "tastes like chicken". Phineas then suggests they "need to try something more...". Ferb responds "Fowl", which Phineas says "Yeah! No! Exotic."

Over at Doofenshmirtz Evil Incorporated, Perry is captured. He is then shocked to find out that Doofenshmirtz has turned himself into a platypus. Believing that turning himself into one would make them equally matched, he created the Platyp-inator, to turn himself into a platypus. To further level the playing field, Doofenshmirtz then traps himself in the same type of trap he had Perry in.

Candace then notices the device in the backyard, and goes to warn Linda. Since Linda is busy doing the laundry/stand-up routine, Candace goes to investigate and wait on her. Perry and Doofenshmirtz then begin to fight and the song A Platypus Fight is played.

She accidentally activates the machine and gets turned to juice. A bird rolls over her, of which she does not approve. Phineas and Ferb then come back, apparently having gone to the store. Baljeet then steps on Candace. Phineas thinks that it is cool that Candace got turned into a liquid. She does not agree, but asks them to help her change back.

Meanwhile, Perry and Doofenshmirtz are worn out from even fighting each other, even Perry sees that it's really difficult to defeat Doofenshmirtz in combat since he's now a platypus. Doofenshmirtz then suggests that they take a break by having tea to cool off. After it is over, the Platypus Fight resumes once more.

The first attempt to turn Candace back involves pouring her into a bucket and reversing the settings on the device to turn her back into a solid. She is successfully turned back into a solid, but in the shape of the bucket she was in. They discover that she needs to be back into her original shape to return to her normal self. They use a life-size mold of Candace that Buford has to do the trick. Baljeet then inquires why Buford has a life-size mold of Candace, to which Buford replies that he has life-size mold of all his friends. Isabella says that she's not so sure how she feels about that. They pour Candace into the mold and zap her with the machine. She walks out of the mold, looking like her original self. After coming out, she then goes to try and get them busted.

In the meantime, Doofenshmirtz and Perry are finally worn out of their energies again, as Doofenshmirtz realizes that he can't win or lose as a platypus, so he decides he needs something stronger. What he comes up with is "two platypuses". He then shows Perry his Double-inator. While explaining his advantage, Perry knocks Doofenshmirtz into the Double-inator, which sends out a stray beam. The beam then hits Phineas and Ferb's device, which creates a duplicate of it. They then zap each other and turn into liquids just before Candace can show Linda.

While Doofenshmirtz is distracted, Perry shoves the Platyp-inator into the Double-inator, defeating Doofenshmirtz. After what appears to be an explosion, Doofenshmirtz says that is good to be back to normal. He is then greeted by another Doofenshmirtz (presumably created by the Double-inator's explosion), who agrees with him. Doofenshmirtz then notices his duplicate, and is visually surprised.

Ferb's Line

Phineas: I think we should try something a little more...

Ferb: Foul?

Phineas: Yeah! No, exotic.

What'cha doin'?


I know what we're gonna do today!/Hey, where's Perry?

Isabella: You know? Buford's kind of right. These smoothies are sort of exotic, but I think we can do better. What do you think, Phineas?
Phineas: What do I think? (Ferb tries to talk, but is halted by Phineas) Don't answer that. Guys, I know what we're going to do today! I wonder what kind of smoothie Perry would like.

Oh, there you are, Perry

Candace: I'm sorry, Mom, but you've gotta see this! Feast your eyes on...puddles.

Linda: Yeah, I saw them earlier.
Candace: But Mom, they had a machine that would turn things into smoothie and--
Linda: I didn't see it, Candace.
Candace: And Buford had a mold, of me!
Linda: Buford's got molds of all of us, Candace.
Phineas: Oh, there you are, Perry!

Memorable Quotes

Phineas: I'm just saying that as a non-sequitur, a talking zebra seems a little...

Isabella: Forced?

Phineas: Yeah, forced.
Baljeet: But Buford, your postcard said that she had a pool.

Buford: She has a patio.
Isabella:(Whispering to Phineas and Ferb) Tomorrow, we should work on Buford's penmanship.

Baljeet: Actually, most would consider dragon-fruit to be that exotic, indeed. (Buford mocks Baljeet with his hand) Known for its dazzling flowers, it is the several.. (Sees Buford mocking him) What are you doing? Stop. Stop that. Stop. Stop it. Stop. (Baljeet starts drinking his smoothie, and Buford mocks him as well) Stop that.
Major Monogram: Come in. Sit down, Agent P. We have a serious problem. It seems that someone, and I'm not saying who, someone has spilled on the couch in the lobby.

Carl: Sir, I--
Major Monogram: A very expensive couch when we bought it in 1985.
Carl: Sir, all I did was turn the cushion over, the stain was already...
Major Monogram: If the responsible party is present...
Carl: Sir, it was Agent M. He spilled a latte in 1990.
Major Monogram: Ugh. We were hoping to get him here a couple of years out of that couch...
Carl: Any who?
Major Monogram: Any who, our surveillance operatives have been getting some mixed signals from Doofenshmirtz. He was observed at the Danville Library, checking out books on Eastern Australia and hydrostatic cell fusion. We haven't come up with any ideas about what he's up to.
Carl: Maybe he's trying to recreate Pangaea, sir.

Major Monogram: Like I said, we haven't come up with anything yet.
Dr. Doofenshmirtz: Well, hello Perry the Platypus! Over here. No, here. Look a little more this way. (Poorly imitates Perry's chatter) What do you think? Huh? I've joined you in the genus Ornithorhynchus. That's right, I am a platypus! (Evil laughter) Yeah, hang on. Let me turn off the dramatic lighting. (claps twice)
Phineas: Isabella, you wanna go next?

Isabella: Why yes, how about a romantic dinner for two. (The device hits the romantic dinner food) Wanna sip, Phineas?
Phineas: Oh, no thanks.
Isabella: Oh, okay I understand. You know you want to keep yourself open to other drink options. I get it.
Phineas: Actually, I didn't want to say anything in front of everybody, but it's I don't like zucchini.

Isabella: Oh.
Linda: Oh, laundry. Sometimes, I feel like our first president because I'm washing a ton. (rimshot) Ah, yeah.
Buford: I don't know, I kinda like her like that. She looks like Cand-berry sauce.
Phineas: We gotta get her back into the right shape before we solidify her. And we're gonna need to adjust the contour in... (realizes what Buford meant and laughs) Cand-berry sauce.
Baljeet: Tell me again, why you have a life-size mold of Candace?

Buford: I've got life-size molds of all my friends.

Isabella: I'm not so sure how I feel about that.
Candace: I'm me, glorious me. You did it, you guys are so... (gasp) o... busted!
Dr. Doofenshmirtz: Curse you, Perry the Platypus! Even though I'm also a platypus at this point, and-- (sighs) I hope this wears off soon. The novelty has worn thin.
Candace: I'm sorry, Mom, but you've gotta see this! Feast your eyes on...puddles.

Linda: Yeah, I saw them earlier.
Candace: But Mom, they had a machine that would turn things into smoothie and--
Linda: I didn't see it, Candace.
Candace: And Buford had a mold, of me!

Linda: Buford's got molds of all of us, Candace.
Doofenshmirtz: Well at least I'm back to normal.

Doof Double: Me, too.

Doofenshmirtz: Oh, good for yo—Whaaaaaaaaaaaa?

  • Since Phineas and Ferb's invention was reversed to make Candace solid again, the duplicate should have been made the same way, and therefore, neither of them should have melted. This is unless the device still had the melting ability or that Phineas and Ferb changed it back.
  • At the tea set with Perry and Doofenshmirtz, the chairs are blue and then turn green.
  • When Candace ends her call with Stacy, the bottom half of her socks are missing.
  • Though Isabella is not supposed to have eyebrows, she is shown with eyebrows during the first scene with the smoothies.
  • When they are playing cards Doofenshmirtz is holding only four cards.
  • Linda should've seen the device when she went to the backyard to see the Candace puddles.
  • The device was next to Candace when she gets zapped but when seen from Linda's perspective, the device is gone, and the Candace puddles are near the tree rather than by the door.
  • When the kids are drinking their smoothies the telephone wire above them isn't connected to anything, it's just floating in the air near a pole.
