"The Doonkleberry Imperative" is an episode of Phineas and Ferb.


When Mom is out of Doonkelberries for her famous Doonkelberry pie, the boys set out to find some for her. Meanwhile, Perry and Dr. Doofenshmirtz find themselves across the ocean as Doofenshmirtz returns home to renew his Drusselsteinian driver’s license. Back in Danville, Candace is convinced she has discovered the answer to her busting problem.


Candace is sitting in her room, asking the "Phenomenon" why Phineas and Ferb's inventions always disappear. As she asks for a sign, she bumps her head into the wall behind her, which drops a book about disappearing objects from the above bookshelf. Meanwhile, Phineas and Ferb are sitting in the kitchen when Linda comes in, the boys would like a Doonkelberry pie but she's unable to find Doonkelberries in town, however, and not knowing where they come from, Phineas and Ferb search the Internet to find that Doonkelberries are the biggest export of Drusselstein.

At the front door, a package arrives for Perry from the O.W.C.A., which he opens. In it is a letter with a talking photo of Major Monogram attached. Monogram tells Perry that Dr. Doofenshmirtz is taking a trip to Drusselstein, and Perry must follow him there but giving him as attire. Afterward, the package and letter self-destruct as Perry takes off after his nemesis.

In the backyard, Isabella and Baljeet help Phineas and Ferb build a trebuchet with which they plan to launch themselves to Drusselstein to collect the Doonkleberries themselves.

Meanwhile, Candace searches for a book in the Danville library called Disappearing Objects to help her bust her brothers. The librarian tells her, however, that it has been lent out to Heinz Doofenshmirtz. But Vanessa, who is visiting the library as well, tells Candace that Heinz is her father, and can help her look for the book in his house.

Perry arrives in Drusselstein, where he stops Doofenshmirtz. He informs Perry, however, that he isn't doing anything evil today, but is simply renewing his driver's license at the DMV. He then asks Perry to accompany him, which Perry accepts.

In Danville, Phineas and Ferb are ready to launch in the trebuchet. Baljeet uses a special machine to bring Drusselstein and Danville close together, which allows them to fly across rather than landing in the ocean. But when they finally reach Drusselstein and find a Doonkelberry stand, the seller tells them that they cannot export because the electricity-providing goat-powered machine for Drusselstein called the shaft is stuck, due to a feud between the people. The vendor explains that half the Drusselteinian population wants their goats to walk to the right, and the other half want their goats to walk to the left, keeping the machine stuck from moving. Phineas, Ferb, and Isabella decide that they want to help resolve the conflict, and offer to help.

Doofenshmirtz and Perry enter the DMV and approach the desk. But much to Doofenshmirtz's dismay, the receptionist tells him that he will have to take a driving test in order to be re-certified. Perry comforts Doofenshmirtz and holds his hand as they walk out to the test. Vanessa and Candace go to Doofenshmirtz Evil Incorporated and begin searching for the book. Vanessa explains as they search in the main lair that her dad is an amateur inventor. But while they look, they unknowingly turn on some of Doofenshmirtz's laser rays, which begin to make objects in the room disappear.

Phineas, Ferb, and Isabella try to negotiate with the Left and Right People, but fail, as neither side is willing to change the direction their goats move. However, they get another idea. On a mountain, Doofenshmirtz sits in a car with Perry, about to take his driving test. The leader gives the signal, and a mountain goat butts into the car, getting the unready Doofenshmirtz started on the test. Doofenshmirtz drives erratically all over town while Perry, scared, holds on tightly until they reach the finish line, nearly destroying the car and the populace in the process.

Candace sees a laser ray on Doofenshmirtz's balcony and looks through it, thinking it is a telescope. Seeing Phineas and Ferb's trebuchet in the backyard, Candace calls Linda, who is in the kitchen. Linda turns around, but as she does so, Candace inadvertently hits the fire button on the inator with her elbow, which makes the trebuchet disappear. Candace disappointingly leaves and tells Vanessa, who has finally found the book, that it isn't worth it.

Meanwhile, Phineas and Ferb explain that they can solve the problem of the machine. Ferb use a saw to cut at the shaft in the middle, causing it to technically be going left and right, solving the Drusselstinians' problem. They are rewarded with fresh Doonkelberries, and then take the people's trebuchet back home. The left and right side people argued again about with Phineas or Ferb name first of the day. Doofenshmirtz, having gotten re-certified, sees the Drusselstein trebuchet, and tells Perry he will take that home. Perry flies off, and Doofenshmirtz launches himself in his car towards Danville with the trebuchet. After eating pie, however, Phineas and Ferb see Drusselstein above them and realize they forgot to separate Danville and Drusselstein. Baljeet fixes this using his machine again, causing Doofenshmirtz's car to fall into the ocean.




  • Phineas and Ferb made the goats go in different directions, but when their change of directions is being shown, both sides are going clockwise, yet people still think that they were going different directions.
  • Phineas does not address the problem that after their modification, half of the devices in Druelselstein will now spin in reverse.
  • When Perry throws the letter from Major Monogram away, Monogram's eyes and mustache are red.
  • When Perry is in the car with Heinz, his flower on his rockenhosen is gone. In the next scene, the flower is back.
  • When Doofenshmirtz finishes his driving test he is bald. Right after, his hair comes back.
  • Just before Doofenshmirtz is about to start the driving test, the shot shows that he is on a cliff. The previous shot shows a longer road.
  • When Candace mentions the rocket disappearing, it was actually Linda's fault that made the rocket fly away.
    • She also mentions the stampeding cows disappearing, but the cows did not disappear, as they were gathered back into a corral.
  • When Zengle shows a map of Druselstein, it is shown "sfa oe" instead of "sea of".


  • The disagreements between those who want the goats to move to the left and those who want them to move to the right satirizes the basic opposition of left-right politics. The two sides are depicted with blue signs for the left and red signs for the right, which are colors commonly used to represent the particular sides in the United States: blue for left (Democrats) and red for right (Republicans).
  • The car in which Doofenshmirtz does the driving test, resembles the much-derided and much-mocked Zastava Koral, otherwise known as the Yugo.
  • Due to a line by Doofenshmirtz, it seems that Perry had an accident during his ride with Doofenshmirtz.
