Rollercoaster (Phineas and Ferb)

Stepbrothers Phineas (Vincent Martella) and Ferb (Thomas Brodie-Sangster) are sitting lazily under the big tree in their backyard when they decide to construct a large roller coaster. With their mother Linda (Caroline Rhea) at the grocery store, their sister Candace (Ashley Tisdale) wants to catch them in the act and "bust" them.

Candace goes to the store to tell their Mom of the boys' activities, though she is keen on neglecting it. Isabella (Alyson Stoner) asks Candace at the Flynn-Fletcher house if Phineas and Ferb are home, but Candace ignores her. Isabella then goes to Phineas with hearts in her eyes and says her common catchphrase "Whatcha doin'?". She says "Isn't that impossible?" to Phineas and asks him to go swimming with her, but Phineas declines and Isabella leaves. Phineas and Ferb begin working on the coaster. Meanwhile, Perry the Platypus (Dee Bradley Baker) performs his act as a "secret Agent P", being informed by Major Francis Monogram (Jeff "Swampy" Marsh) that Dr. Heinz Doofenshmirtz (Dan Povenmire) has bought 80% of the Tri-State Area's tin foil. Perry darts off to investigate what Dr. Doofenshmirtz is doing.

With their rollercoaster finally finished, Phineas and Ferb unveil it to the neighborhood children in a glamor-filled light show with notable guests being Isabella, Ginger, and Katie. They immediately climb up the lift hill as Phineas shows everyone how to fasten their seatbelts, he then drops it after showing everyone how to release the buckle on the seatbelt, he then sits back down as the ride crests the top of the hill. It then pauses, and Phineas double checks to make sure everyone signed the waivers, then the rollercoaster rockets down the first 3-mile drop and begins the wild ride. There are loops, twists, and turns. After that, the rollercoaster flips through the corkscrew around the interstate, and rubber snakes dump on everyone as they are screaming at the top of their lungs until Phineas says “Relax! They're Just Rubber!”, The rollercoaster then dives into a mud bucket before immersing back out and going through a carwash. The rollercoaster then comes to a complete stop as everyone is now squeaky clean, an attendant rubs the nose of the front car and waves goodbye. The rollercoaster then zooms away, takes a quick trip through the "AH-AH-AH-AH!" section, and turns through several loops around Doofenshmirtz Evil Incorporated.

Doofenshmirtz, meanwhile, reveals that he is using the tin foil to cover the eastern seaboard, then using a magnet to pull it, thereby reversing the Earth's rotation. Perry fights him, but Doofenshmirtz manages to get the magnet activating. However, Doofenshmirtz soon learns that his plan is flawed because the magnet has only taken the tin foil off the eastern seaboard, forming it into a 2-ton giant ball. Seeing that it's heading forward, Doofenshmirtz decides to separate the magnet from his machine to stop it, and Perry is forced to help him out.

Perry attempts to solve the problem by hooking the magnet to a helicopter, causing the magnet to go with it. Doofenshmirtz is happy about being saved, but is then crushed (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 rollercoaster. Agent P, who 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 rollercoaster drop to the ground. The kids are still on the very fast rollercoaster and have just entered the wildest sections of the ride. 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 rollercoaster reaches the broken end of the track 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. The rollercoaster 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. The rollercoaster cars 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 continues to try and bust them, even on the way home. The magnet is stopped, as Phineas and Ferb return home, Candace a second too late. Isabella says that was the best ride ever and she and Phineas talk about Perry and that he may lay an egg. Ferb burps from having peanut butter, which Isabella says was cool, and she leaves at that point. The episode ends with the roller coaster exploding in the boys' backyard tree and tin foil ball is seen rolling in the background setting. Upon the rollercoaster exploding Candace tries to bust the boys again. Mom responds by saying, "Give it a rest, Candace!"

The episode originally aired as a preview after the premiere of High School Musical 2 on August 17, 2007, with a rating of TV-Y7. Disney Channel wanted to start off the series in a special way, though they did not to use "Rollercoaster"; instead, they choose the episode "Flop Starz", and aired it in a worldwide premiere.[12][13]

The events of "Rollercoaster" would be revisited in the season 2 episode "Phineas and Ferb's Quantum Boogaloo", which sees a future adult version of Candace returning to the events of the episode in a time machine to help her present counterpart successfully bust Phineas and Ferb for the rollercoaster. However, this action led to a chain reaction that soon followed, turning the future version of Danville into a dystopian society led by subplot antagonist Dr. Heinz Doofenshmirtz.[17] Later, the same Candace goes back into the past to stop the adult Candace from causing the disaster.

Inspired by the Star Trek: Deep Space Nine episode "Trials and Tribble-ations" (which saw the crew of the newer series interacting with the events of the original series episode "The Trouble with Tribbles"), the use of "Rollercoaster" within the plot was viewed by Marsh as "a great way to interweave a story."[17]

When Candace and her mother leave the supermarket and are walking from the parking lot, the two future Candaces can be seen behind a car. Also, while the roller coaster is flung into space, Meap can be seen in his spaceship. For the finale of the episode, the cast of the show performed "Carpe Diem" and almost every major and minor character from previous episodes of the show made cameos in the performance, including the Goozim from the episode "Got Game?". Kenny Ortega made a special cameo as the choreographer of the performance.

Various phrases from the original episode were made into songs with two songs added in the episode, including:

• "Hey Ferb" (Phineas)
• "You're Going Down" (Candace)
• "What 'Cha Doin'?" (Isabella)
• "Monogram Box Song" (Major Monogram)

• "Aren't You a Little Young?" (Phineas and the Delivery Man)
• "Back in Gimmelshtump" (Dr. Doofenshmirtz)
• "Rollercoaster" (Phineas)

1.^ Original broadcasts and the sneak peek of the episode have the song in the end credits. Other airings, however, include the song at the end of "Lawn Gnome Beach Party of Terror!" instead whilst others have Major Monogram singing: 'My Whole World is a Screen'.
