The Big Break

Phineas and Ferb build another rollercoaster for unknown reasons, and Doofenshmirtz builds his "speed-it-up" inator to speed up the lines in restraunts, stores, etc. so he can order stuff faster, but Perry makes him mis-shoot and it hits the rollercoaster, and they end up falling off in the backyard. Everyone ends up okay except for Phineas, who breaks his arm.

Episode Summary
Phineas and Ferb are sitting under the tree in their backyard, when Phineas tells him to bring back memories, they should build a rollercoaster AGAIN. Isabella comes in and asks what they are doing, and Phineas tells her about building a rollercoaster to bring back memories. Isabella is suspicious, as it's the third time.

Perry puts on his fedora and goes to the back of the tree, and goes into his lair through the tree. He goes to his chair, and Major Monogram tells him that Dr. D is building a "speed-it-up" inator, then Perry leaves and goes to his rocket-car and transports to Doofenshmirtz Evil Inc.

Phineas and Ferb are almost done with their mini-rollercoaster. Phineas tells them it's a mini rollercoaster that goes five laps or more. They get finished with it and go on it. They set it to five laps. They say they love it and it's amazing and want to do it for another 3 minutes. Then, Phineas sets it to 50 laps.

Perry arrives in Dr. D's lab, and then Dr. D is done. Perry fights him, and the machine explodes, leaving one shoot alright shot and aimed at the rollercoaster. It then hits the rollercoaster, and they all fall off the rollercoaster. The rollercoaster ends its final lap. Everyone gets up. Isabella asks if everyone's ok, and everyone except Phineas say yes. Phineas lays on the floor in pain. Isabella and Ferb check on him, and they use a quick x-ray and see Phineas broke his arm. The rollercoaster, apparently, blows up along with its track when Perry uses a jetpack to come back and bumps into the trash can which hits the rollercoaster's self-distruct button. They then take him to the hospital.

Clamshot is working on this.
