The Phineas and Ferb's Super Skate Course of Doom, also known as The Phineas and Ferb's Edge-of-Insanity-Kiss-your-Butt-Goodbye-Gravity's-a-Stone-Cold-Sucker-Nightmare-Rail-Skate-Track-Obstacle-Course-of-Doom was built by Phineas and Ferb so they could have the coolest skateboarding experience ever! When they finished it, as they where about to skate down it, Phineas' skateboard fell and got hit by every obstacle on it, and finished off by exploding. Phineas realized they could get hurt, and tells Ferb they need to take the stairs down. When they reach the bottom, Isabella arrives and asks if she can put them in the newspaper, Phineas tells her they need to tweak it first, and she leaves. They then have the idea to modify themselves, and create the Beak. The Beak later uses his grappling hook to stop, and wraps around it, mostly destroying it, and Phineas later states that the suit makes cleaning fun and easy. It is unknown if they really do this, but he later asks Khaka Peü Peü if he want to help them rebuild their skateboarding course.
