Isabella and the Temple of Sap

While Phineas and Ferb get the bubble ready, Isabella and the Fireside Girls head out to the "Old Abandoned Old Abandoned Amusement Park" where the maracanut tree is and try to get the sap from it. Meanwhile, Isabella's pet dog, Pinky tries to stop his nemesis, Professor Poofenplotz, from stealing hairspray.

Episode Summary
The episode starts inside Isabella's bedroom where she wakes up and gets ready. She tells her chihuahua, Pinky, to try talking in the 3rd person but Pinky just barks. Isabella then goes to the Fireside Girls club house, which is a shed in the middle of the woods to meet up with the rest of the Fireside Girls. The Fireside Girls are discussing their patches when Isabella enters and says they should go an see what Phineas and Ferb are doing. Milly and Ginger complain they already have enough "Help Thy Neighbor" patches from them but then they all realize that Isabella just wants to see Phineas. Ginger moans that they always see what Phineas and Ferb are doing, never Baljeet. But Milly and Holly remind her that they did that before and the patch was not worth earning.

Pinky waits for the lift to arrive to go to his/her headquarters to receive news about Professor Poofenplotz. Poofenplotz is apparently looking for 'Stiff Beauty' hairspray for herself, which has been discontinued. Pinky goes to Poofenplotz's place and gets caught in a trap. Poofenplotz explains what she is doing and why and says that she is going to the Old Abandoned Old Abandoned Theme Park to look for the supply of 'Stiff Beauty' hairspray used by clowns who used to work there.

Isabella and the Fireside Girls arrive at the park with Isabella saying "Whatcha doin'?". Phineas says that he is not really sure what he has been doing "with always getting wrapped up in these silly projects I don't care about-- it's you I care about, Isabella!" and grabs Isabella's hand saying they should run off together. Phineas turns into a centaur and Isabella climbs onto his back and they ride off into the sky with a rainbow trail. Isabella snaps back from her fantasy, accidentally agreeing to what Phineas says and then panics and asks Gretchen what he asked her to do. Gretchen explains that he wanted the sap from the rare Maracanut tree. The Fireside Girls decide to climb the mountain where the trees are supposed to be but they only find a man playing a didgeridoo. Isabella asks where all of the trees are and the man moves out of the way and shows all of the trees had been cut down for a hairspray. He then hands Isabella a key and tells her to go to the Old Abandoned Old Abandoned Theme Park. The man disappears but then Gretchen spots him. He tells them he was just going.

All of the Fireside Girls arrive at the 'Old Abandoned Old Abandoned Theme Park' and they search for the tree. They then realize it is on the top of a high rollercoaster but the tunnels that surround it are too weak to climb. Isabella claims that Fireside Girls never give up and they all sing a song about Fireside Girls. Isabella remembers the key she was given and presses a button. A mini-camper with flowers unlocks on top of the rollercoaster before it enters the tunnels. All the Fireside Girls climb into it and ride the rollercoaster down. It flies off the edge up near the Maracanut tree. Isabella realizes before it is too late that someone needs to get out and grab that tree so all of the girls tie their sashes together and Isabella climbs out of the car. She grabs the tree and tumbles into the back of the car. The tree is about the size of a bonzai tree ("Oh, my goodness, what a cute little tree!"). The car lands on the road and continues racing forwards whilst Holly and Katie get the sap out of the tree.

Poofenplotz climbs into a giant robot shaped like her head and picks up Pinky. The robot walks outside and dumps Pinky into the trash can. Pinky tries to escape when Candace comes along in her car and knocks down all of the trash cans, letting Pinky escape. Pinky grabs a jet pack and flies over to where Poofenplotz is. He lands inside the robot and Poofenplotz presses a button which makes a newspaper hit him. Pinky throws the newspaper at Poofenplotz and shoots an arrow towards a building with a string attached. This stops the robot moving until the car Isabella and the Fireside Girls are in snaps the string.

They are successful and the car crashes into the park. The girls run over the where the others are and they give them the sap. Phineas thanks Isabella by turning into a horse and he and Isabella ride off into the sky again. Isabella snaps out of her daydream and asks Gretchen again what he said. Gretchen replies by saying he said thanks.

The last scene is Poofenplotz tumbling out of the robot into the theme park. She finds the supply of hairspray Ginger found earlier and holds a high, long note of glee, causing half of the mountain the rollercoaster was in falls onto the hairspray. The hairspray saturates Poofenplotz and she is stuck in the position she last was in, slightly glossy. The episode ends with her cursing Pinky the Chihuahua.

Errors

 * When Isabella addresses that the girls never give up before "the Fireside Girls Song" starts, the collar on Ginger's top is the same color of orange as the rest of her top, instead of the reddish-orange it normally is.
 * Isabella is seen with messed-up clothes and hair, but never was seen at an attraction until the van was seen. She may have went to an attraction during an unseen time based on her dialogue ("So let's find that sap! Fireside Girls, report!").
 * The girls have their sashes back after Isabella has the tree, but before that in the next scene, Katie and Milly don't have a sash on.
 * In some scenes, the clouds are moving, in others, they are not.
 * Just before the girls see the van, Adyson is next to Isabella, but when it is seen Ginger is next to Isabella.
 * When Isabella comes back in the van with the tree, she is seen wearing sashes connected to each other. However, in the next scene there are no sashes. In the next scene, Isabella is wearing the sashes again.
 * Isabella addresses the troop as 46321, but Jeff "Swampy" Marsh has said it's 46231 (Swampy Correspondence).
 * It is illegal for a person under the age of 18 to drive without a learner's permit. It is unknown if the police will find out sooner or later.

Continuity

 * This is the second episode that occurs during another episode ("Bubble Boys"), the first being "Unfair Science Fair" and "Unfair Science Fair Redux (Another Story)".
 * In the beginning, Isabella is seen in pajamas, which was also seen in I Scream, You Scream.
 * We first learn of Pinky's secret agent life in "Day of the Living Gelatin". We also see the return of Wanda.
 * Isabella paraphrases the famous "Hey, where's Perry?" at the beginning of the episode, saying "Hey, where's Pinky?".
 * During the scene where Professor Poofenplotz is in the store, Gitchee Gitchee Goo and I'm Lindana and I Wanna Have Fun! can be heard in the background.
 * However, it cuts to Lindana in the middle of Gitchee Gitchee Goo.
 * Isabella imagines Phineas with hearts in his eyes when he 'confesses' to her. In ("Rollercoaster"), she is seen looking at him with hearts in her eyes. Candace also used hearts in her eyes looking at Dennis in No More Bunny Business.
 * The place Prof. Poofenplotz's Me-Mobile is stuck is around the place Dr. Doofenshmirtz parks and goes to the science fair ("Unfair Science Fair").
 * Isabella's fantasy of Phineas turning into a centaur may be a reference to her love of horses and unicorns ("The Magnificent Few", "Hail Doofania").
 * This is the second time they had to use their sashes to get them out of a dangerous situation. The first time was in "One Good Scare Ought to Do It!!" when they rescued Phineas from falling.
 * This is the second episode to not have an Agent P plot (The first being Phineas and Ferb Get Busted).

 * This is the fifth time that Ferb does not speak (The Fast and the Phineas, I, Brobot, Interview With a Platypus and Tip of the Day).
 * Poofenplotz's Me Mobile is much like Heinz Doofenshmirtz monster truck that he drove in It's a Mud, Mud, Mud, Mud World.
 * Candace would later make a cameo appearence in "Brain Drain".

Allusions

 * The title is based upon.
 * When the girls first see the Flower Power van (A 1961-64 Chevrolet Corvair Greenbrier), they use 1970's slang, including "Dy-no-mite!" (often said by Jimmie Walker in the series Good Times) and "Jinkies" (catchphrase of Velma from "Scooby-Doo, where are you?". Also, when the girls carry out their plan to use the van to get the tree, the theme music from the 1975-76 TV series S.W.A.T. can be heard.
 * The mirror above Isabella's bed is in a Star of David frame, a common symbol for Judaism.
 * All the Maracanut Trees being cut down to make hairspray may be an allusion to The Lorax by Dr. Seuss, where trees are cut down for commercial uses.
 * The guru's shades are reminiscent of John Lennon of Beatles fame.
 * Poofenplotz's building looks similar to the Sega Saturn logo.
 * When the Fireside Girls look at the Chevrolet, a riff similar to the intro to Castles Made of Sand by Jimi Hendrix plays.
