Rollercoaster

Phineas and Ferb construct a roller coaster from their backyard out to the whole city for themselves and the neighborhood kids. Perry the Platypus attempts to thwart Dr. Doofenshmirtz's evil plan to halt the Earth's rotation. This is also the first episode of the series.

Episode Summary
Phineas and Ferb are sitting under a tree, wondering what to do. Phineas realizes that they will be back in school shortly and they will have to say what they did over their summer vacation. He feels that their time off should be exciting, like a rollercoaster. Remembering the lame coaster they rode at the State Fair, Phineas realizes that's what they should do today: build a rollercoaster.

As their mom, Linda, heads off to do some shopping, Candace runs to her car to confirm that she's been put in charge. Mom doesn't think it's necessary that anyone be in charge, but Candace does. "What if a satellite falls out of orbit and crashes into the house?" It's not likely to happen, so her mom gives her approval and Candace rushes over to tell the boys, "Mom says I'm in charge! ...Conditionally!"

That doesn't bother Phineas. He and Ferb have set up drafting tables and have started working on their "homework". Candace doesn't understand why they would be doing homework during their summer vacation. She heads into the house after admonishing them that they are being watched, and reminds the boys that she's in charge, conditionally.

Candace only gets to take one look out the window before the phone rings. It's Stacy, wanting to go to the mall with her. She can't go because she has to watch her brothers. Candace makes sure that Stacy will see if Jeremy is there.

While Candace been talking on the phone, the boys and Perry have been transporting various building materials into the back yard: lumber, steel I-beams, a jackhammer and plumbing supplies. The lion's roar breaks her concentration and she yells at the boys, "Will you hold it down, I am trying to use the phone!". Going back to talk to Stacy, she gets her first hint that something is wrong. Stacy tells Candace that she can see something being built in the back yard from her house.

Candace runs out to the back yard, then stops in her tracks. She looks up and sees a patchwork of pipes and track. Whatever it is, she doesn't like it. She storms off to tell mom, proclaiming that the boys are going down. She repeats it several times and spells it out for emphasis. "We're going to need a blowtorch and some more peanut butter" is Phineas' assessment.

As Candace rides off on her bike, Isabella walks into the yard with hearts in her eyes. "Whatcha doin'?" she asks. Phineas tells Isabella that they are building a roller coaster. Isabella then says hi to Ferb, but Ferb only waves his sledgehammer in response. As a man of action, he's busy laying track. He strikes a rivet with the sledgehammer, causing it to bounce and hit him on the nose. Ferb just blinks, apparently unhurt. Isabella had stopped by to invite Phineas to go swimming with her, but he wants to work on the coaster, so she heads off. Phineas then notices that Perry is missing.

Perry is walking nearby alongside the house. He stops and checks to make sure no one can see him. Jumping up onto his rear legs, Perry's demeanor changes. He is no longer a platypus that "doesn't do much". He puts on brown and black fedora, becoming "Agent P". A remote control opens a hidden door in the siding. Agent P steps in and rides the tube elevator down to his lair.

Major Monogram informs him that Dr. Doofenshmirtz has bought "80% of the country's tin foil". Agent P must find out why and stop him. Before Agent P leaves, Major Monogram reminds him to maintain his cover as a "mindless domestic animal". Giving the Major a quick salute, he flies off in his platypus-shaped hover-jet. He exits to the surface through a tunnel. Shortly thereafter, he flies by the boys and pulls his hat down over his face to avoid being recognized.

The boys are taking a break from construction to discuss the next part of the coaster. There will be solid-fuel booster rockets and snakes being released during a corkscrew around the Interstate highway. Phineas heads off to get the snakes while Ferb resumes welding.

Meanwhile, Candace has been trying to get her mom to come home from the grocery store and see what Phineas and Ferb are doing. Linda mentions that she recalls Candace doing the same thing previously, claiming that the boys were training "monkeys to juggle bicycles," but when she came home, "there was a stunning lack of monkeys". Candace persists, telling her about the roller coaster. Linda thinks Phineas is a little young to be a roller coaster engineer.

At that moment, a foreman at a car factory is asking Phineas the same question. After Phineas confirms it, the foreman approves their building permit despite it being filled out in crayon. He offers to give them whatever help they need, so Phineas takes him up on the offer and borrows one of the robotic assembly arms. In short order, the robot arm is mounted to the coaster cars and is laying out track for them.

Nearby, Agent P swings in through a window at Doofenshmirtz Evil Incorporated. Dr. Doofenshmirtz greets him with: "Ah, Perry the Platypus! What an unexpected surprise. And by unexpected, I mean completely expected!" After trapping Agent P, the doctor informs Agent P of his plan to move the Eastern Seaboard (now covered in tin foil) to the West by using a "Magnetism Magnifier", which will stop the rotation of the Earth. While Doofenshmirtz is talking, Agent P tries getting free of the robot arms holding him, but then notices a screw on the ground at his feet. Looking around him, he formulates a plan....

Back at the Super Food Stuff Mart, Candace continues her attempts to convince her mom to come home. She sees the poster that Ferb has just put up, but when she gets her mom over to there, two boys have taken the poster to see if they can get in for a discount. Candace screams when she sees that the poster is gone. Mom informs her she'll be over in the dairy section if Candace wants to "come yell at some cheese or anything".

Phineas and Ferb unveil the Coolest Coaster Ever to the neighborhood kids. The first lift hill climbs up through the clouds, high enough that a bird flies into the track and falls to the ground.

As they start to go up, Phineas is sing everybody how the seat belts work, but he drops it. The coaster comes to a stop at the top of the lift hill, revealing part of downtown Danville far below them. He asks everybody, "You all signed the waivers, right?" They then shoot down and begin the wild ride. There are loops, hairpin turns, and the promised corkscrew. A load of rubber snakes falls on them just before they plunge into a mud bucket. Fortunately, the next section includes a trip through a car wash and they all emerge squeaky clean. Next is an "A-A-A-A" portion and a few loops around Doofenshmirtz Evil Incorporated.

Inside, Dr. Doofenshmirtz is still rambling on about how much this scheme cost him. Agent P uses his tail to fling the screw at Doofenshmirtz, "missing" him, making it rebound and hit him in the foot. Hopping around, the doctor accidentally releases Agent P from his robotic arms. Agent P then starts to battle him with wrenches and strikes the same foot of Dr. Doofenshmirtz that the screw hit.

During the fight, Dr. Doofenshmirtz runs over to the Magnetism Magnifier and turns it on, telling Agent P he is too late and it cannot be stopped now. But the Eastern seaboard did not move to the west, just the tin foil, causing a two-ton ball of tin foil going, at two hundred miles an hour to head straight for them. They both frantically try to turn it off.

At the store, Candace and her mom are at the checkout when Candace hears the coaster going by. She sees the coaster track out in the parking lot and goes back to get her mom so she can see as well.

Agent P is now helping Doofenshmirtz in trying to move the Magnetism Magnifier, but it will not budge, so he hooks the magnet to a helicopter, causing the magnet to go with it. Dr. Doofenshmirtz is happy about being saved, but is then moved (along with the rest of the tallest part of the building) by the tin foil ball that crashes into it. The magnet attracts the Magnetism Magnifier, which sends a magnetic ray at the track under it, picking up the entire roller coaster.

Candace gets her mother out of the store, but the roller coaster track has already been moved. Since the mom has finished checking out, the two leave, and Candace is now excited because she believes that when they get home, the boys will not be under the tree, therefore proving to her mom that she is right.

Agent P has been riding on top of the magnet and notices that the helicopter has been trailing a plume of smoke from the strain of lifting that much weight. He cuts the cable, making the roller coaster drop to the ground. The kids are still riding this very fast coaster. Agent P jumps onto the coaster with the kids as it passed beneath him. Phineas looks behind him and utters the famous catch phrase, "Oh, there you are, Perry." Instead of seeing Agent P, Phineas sees Perry again, since Agent P put his hat on Isabella a moment before, so he wouldn't be recognized.

The kids reach the broken end of the coaster and ride out into the street, through a construction site and up onto the tail of a passing jumbo jet after a crane swings them up into the air. Candace, in the car below, sees the boys on the airplane flying in the other direction and laughs gleefully. Mom says she worries about her sometimes.

The coaster cars finally come loose from the tail of the jet and they fall onto the Statue of Liberty. It bends and then flings them over to Mount Rushmore, where they do some loops inside Theodore Roosevelt's glasses. They then shoot out on a tree over a Mr. Slushy Burger, then get flung to Paris where they land on a very bendable Eiffel Tower over a croissant stand, finally getting flung all the way into outer space. A satellite passes by the coaster, and Phineas points out that if it falls to Earth, Candace is in charge. At that moment, the coaster plummets to the Earth, picking up speed and catching the nose of the first coaster car on fire from the friction of re-entry. As they get closer to Danville, Phineas says, "We should've charged more."

Candace and Mom now pull into the driveway and Candace runs out of the car, laughing crazily. She looks into the backyard, and does not see Phineas and Ferb and shouts "yes!" She tells her mom she told her, closing her eyes and extending her hand out to point at the yard, as we hear a rustle of leaves. The mom says "Hi" to the boys, sitting under the tree. She walks into the house, Candace gasping "But" over and over again until Mom pulls her into the house.

The kids now fall out of the tree, all saying how much they liked the ride. Isabella falls out of the tree, telling them how great it was and asking them what they're going to do tomorrow. Phineas says he doesn't know, and Isabella suggests teaching Perry some tricks. Phineas says that platypuses don't do much, followed by Ferb saying his first spoken words in the show: "They're the only mammals to lay eggs". Phineas says maybe he'll lay an egg, and Isabella leaves, saying it really was the best coaster ever and the two make a great team. Phineas replies, saying that he couldn't have asked for a better brother than Ferb, who then burps. Phineas comments that he can smell the peanut butter.

Phineas then asks what they should do tomorrow, and suggests making a list. Just then the top of the tree explodes, causing Candace to shout, "Mom!", who responds with, "Give it a rest, Candace!".

Background Information

 * This was the first episode to air, following the premiere of High School Musical 2 on August 17, 2007. It garnered a total of 10.8 million viewers.


 * The cars that Phineas and Ferb use for their coaster are the same as what is used at the State Fair, and several of the kids that rode with them at the State Fair rode their new coaster.
 * Phineas's voice is different than it is now, possibly due to Martella experiencing puberty.
 * Creator Dan Povenmire's real voice makes a cameo as the automobile factory manager who notes that Phineas' building permits are filled out in crayon.
 * This is the first episode with a song in the end credits that wasn't featured in the episode.
 * Katie and Ginger make an early cameo in this episode; they appear in a crowd shot during the unveiling of the coaster, but they did not wear their berets and sashes.
 * The employee at the Mr. Slushy Burger stand in the woods is not specifically identified as Jeremy, but does look like him. He could be Jeremy, because, In The Latin American version of the show, that employee speaks with Jeremy's voice
 * This is the first episode to use real live-action images.
 * Stacy was first mentioned in this episode.
 * If you look hard in the Ah-ah-ah-ah! scene, you will see a sign that reads: "Exclamation Finance".
 * A scene related to the show can be seen in the credits, just like in many other Disney cartoons.
 * Ferb only speaks at the end of Rollercoaster.
 * Mt. Rushmore, the Eiffel Tower, and the Statue of Liberty can be seen in this episode, though the Eiffel Tower and Statue of Liberty shouldn't have been able to bend due to them being solid metal.
 * The boys are shown carrying a lion through their backyard, but it isn't seen on the roller coaster, though it is possible it was used off-screen.
 * Nitpicker's Guide: In "Phineas and Ferb's Quantum Boogaloo", Candace states that this date was the first day of the summer, but Mrs. Flynn states that Candace told her about another of the boys' ideas, making it at least the second day. Although it may have happened after the last day of school.
 * The helicopter has Ukrainian flag on it.
 * The Phineas line: "...and boredom is something of up with which I will not put!" is a take off on a quote (often misattributed) from Winston Churchill as a way of preventing a sentence from ending in a preposition.
 * Goof: The boys borrow one of the 'contraptions' at the automotive factory in order to speed up the building process. The rail passes by Doofenshmirtz Evil Incorporated and continues past it. But as the kids are riding the rolllercoaster later on, they ride on spiraling rails that wrap around the outside of the building.
 * Goof: When Ferb goes on the stage before unveiling the rollercoaster, Katie is in two places at once.
 * Goof: Before the unveiling of the rollercoaster, when Katie and Ginger are seen from behind, they have their berets on, but when they're seen from front, they aren't worn.
 * Goof: When Perry was captured by Dr. Doofenshmirtz, there was no nail underneath him, but later there was a nail underneath him, which he uses to attack Doofenshmirtz.
 * Goof: After Dr. Doofenshmirtz gets the nail stuck in his foot, there is no blood, but because the nail pierced the skin, he should have been bleeding.


 * (Possible) Goof: After Perry escaped from Dr. Doofenshmirtz's mechanical arms, Dr. Doofenshmirtz grabs a wrench to fight Perry, who also had a wrench, but we never see Perry pick up the wrench. At this time, the nail that got stuck in Doofenshmirtz's foot disappears.


 * Goof: While Perry was in Doofenshmirtz Evil Inc., a machine breaks a window, we then see the outside of Doofenshmirtz Evil Inc., and there's a hole in the wall, but after we see the outside of the building again, there's no hole in the wall.


 * Goof: Candace drives to the store on her bicycle, but she later drives home with her Mom, and she doesn't take her bicycle.


 * (Possible) Goof: When the roller coaster was flying by the satellite, Phineas knew that if it crashed to Earth, that Candace was in charge, but Candace never told Phineas and Ferb the condition that would allow her to be in charge, so how did Phineas know?


 * Goof: Ferb's platypus line is technically incorrect, being that long and short nosed echidna also lay eggs.

Continuity

 * Permanent Continuity change: Phineas' voice sounds slightly lower from the second episode, onward
 * I'm Lindana and I Wanna Have Fun! can be heard as "elevator music" when Candace and her mom are shopping at the Super Food Stuff Mart.
 * The events of this episode are later revisited in "Phineas and Ferb's Quantum Boogaloo", with the battle between Agent P and Heinz Doofenshmirtz one of main events that alters the future.
 * Perhaps in a short-lived carry-over from the Original Pitch, Phineas is more arrogant and sarcastic in this episode. For example, rather than happily admitting what he and Ferb are building, he dismisses Candace with a quick "whatever" and tells her they are doing "homework".
 * This episode is referenced many times later (probably because it's the first episode).
 * Doofenshmirtz's invention doesn't end with -inator.
 * In I Scream, You Scream, Candace tells Phineas that she is in charge. He becomes confused, and says, "isn't that just if a satellite (crashes into the house)?"

Allusions

 * Wizard of Oz: Candace's theme that plays when she rides her bicycle is very similar to the theme for Miss Elmira Gulch/Wicked Witch of the West in the 1939 movie .
 * The name "Mr. Slushy Burger" is based off "Mr. Slushy" from the "Veggie Tales" episode, "Larry-Boy and the Fib From Outer Space."
