Here it is, this may be the only place in the world to get Doonkelberries right now.

Phineas Flynn

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.

Episode Summary

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. Afterwards, 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 explain that half the Drusselteinian population want 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 inadevertly 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.
