The Coolest Coaster Ever is the name Phineas and Ferb gave to their roller coaster they constructed for an early Big Idea. Like the name suggests, it is a huge roller coaster that goes around the whole city. Agent P lifts the coaster in the air with a helicopter as part of trying to complete his mission, and after it is set down again, the coaster goes off course to places like Mount Rushmore, Paris, a Mr. Slushy Burger and outer space, by a satellite.
In trying to decide what to do and realizing that he won't put up with boredom, Phineas tells Ferb that they need to be ready to tell what they did during their summer vacation when school starts up again. He reasons, "I mean, no school for three months. Our lives should be a roller coaster. And I mean a good one, not like the one we rode at the State Fair."
That coaster was lame, and Phineas begins thinking out loud that if he built a roller coaster, it would be better and that gives him an inspiration. Thus the Coolest Coaster Ever is born. ("Rollercoaster", Speed Demons)
Design and construction
Phineas and Ferb set drafting tables and blueprints for their "homework". Almost immediately, the boys are ready to begin and haul various construction materials into the back yard, including lumber, steel I-beams, a jackhammer, plumbing supplies, a plastic flamingo and a lion in a cage. (The placement of the lion and its role in the coaster's construction has not been revealed, as if probably for just comic relief.)
Phineas and Ferb start the construction at the backyard. Phineas decides they need a blowtorch and some more peanut butter. A query by Isabella as whether building the coaster would be impossible doesn't phase them, and Phineas passes up an opportunity to go swimming so that the coaster can be completed.
During construction, they boys pause to discuss the features of the coaster. Solid fuel rockets will ignite at the grocery store parking lot and snakes will be released during the corkscrew around the Interstate highway. Shortly thereafter, as the coaster construction passes through a car factory, Phineas gets permission to use one of the assembly robots, and it is quickly adapted as an automatic track layer thus giving them an advantage. The track passes in front of the Doofenshmirtz Evil Incorporated building, and would later make several loops around it. ("Rollercoaster", Speed Demons)
Advertising and unveiling
The use of the automatic track layer speeds up construction. Ferb then proceeds to put up fliers, one of which was at the grocery store discussed previously by Phineas. Three kids take the flier to ensure they would get a discount on the admission fee, much to Candace's annoyance of not being able to bust her brothers.
Phineas and Ferb put up an entrance to a huge circus tent in their back yard in which to unveil the coaster. There is a limited number of riders and Phineas starts to present the coaster by removing the curtain that hides it. Everyone is awestruck and wants to ride it. ("Rollercoaster", Speed Demons)
Riding the coaster
During the ascent of the first straight lift hill, Phineas provides a demonstration of how to operate the seat belts, but drops the demonstration unit. At the top of the lift hill, he double-checks to make sure everyone signed the liability waivers.
From there, the coaster starts the wild ride with a 3-mile drop straight down. The riders experience loops, barrel rolls, sharp turns, rubber snakes being dropped on them while doing a corkscrew aroung the Interstate Highway, being immersed in mud, getting squeaky clean after a trip through the car wash, and the "Aaah-aaah-aaah-aaah" section. ("Rollercoaster", Speed Demons). In Rollercoaster: The Musical!, there are new additions to the Track, such as going upside-down through a Subway, a segment with a Dog sleeping in the middle of the Track (which wakes up and quickly jumps off), new hills, helix around a building and an area with various Loops.
Going off course
While they are riding the coaster, Agent P needed to get rid of one of Dr. Doofenshmirtz's inventions, so he fires a grappling hook at a passing helicopter. The magnet at the end of the grappling hook latches onto the coaster and the helicopter flies away with it. Seeing the strain the weight is putting on the helicopter, Agent P cuts the cable. The coaster drops back down to the ground, and the wildest sections of the coaster begin, with Perry as an addition passenger.
The coaster runs off the broken end of the track, up the back of a truck like a ramp, then gets flung into the air by a construction crane. A passing airliner jet catches the cars on its tail, and afterward the coaster makes its way from the Statue of Liberty in New York, to Canada (in "Rollercoaster: The Musical!" which Phineas comments about the moose), to Mount Rushmore, over to a Mr. Slushy Burger, across the Atlantic Ocean to the Eiffel Tower in Paris, and finally up into outer space. After a few moments that allow Phineas to comment on the satellite passing by (the satellite didn't appear in "Rollercoaster: The Musical!", instead Meap appeared in his spaceship), the coaster falls back into the Earth's atmosphere. ("Rollercoaster", Speed Demons)
At the end of the ride, the coaster lands in the tree in the boys' back yard. The kids climb out of it and are eager to ride it again, but Phineas says, "Sorry, only one ride per customer." The discussion then turns to what they will do tomorrow, but Phineas and Ferb don't know yet. Later, he says "So what should we do tomorrow? There's a world of possibilities. Maybe we should make a list!"
At this point, it is not known what became of the coaster as it was not shown being dismantled or disposed of. It was mentioned several different times later in the summer. ("Rollercoaster", Speed Demons)
Later, it was revealed that Perry copied data from it and his computer replicated it to use in the fight against 2nd Dimension Doofenshmirtz. (Phineas and Ferb the Movie: Across the 2nd Dimension)
The fate of the coaster's tracks get revealed in Milo Murphy's Law where at least part of the track ends up falling into the backyard of Melissa, crushing her science project and scarring her for the rest of her life.
In an alternate reality, a future Candace manages to bust her brothers midway during the coaster, specifically in the section at the grocery store. Due to this, Linda is scared their children are riding such a dangerous ride and calls the police and firemen. The pilot of the helicopter knowing of the incident flies away, and Perry couldn't fire the grappling hook, so the track isn't moved. The kids are brought down from the coaster by several firemen and Phineas and Ferb gets busted. ("Phineas and Ferb's Quantum Boogaloo")

- The Coaster was first seen by Stacy. ("Rollercoaster", Speed Demons)
- The tree in the back yard that was damaged is artificial, and was repaired shortly afterward. It is used as both as an entrance to Agent P's lair and an exit for his hover jet. ("Ready for the Bettys", "The Fast and the Phineas") It would be later used as "The Nest" for the superhero, The Beak.
- The Coaster is an important plot point for three different episodes, more than any of the other Big Ideas. The episodes are "Rollercoaster", "Phineas and Ferb's Quantum Boogaloo", and "Rollercoaster: The Musical!"
- The Coaster is also the only Big Idea to appear at least once every season.
