Coolest Coaster Ever

The Coolest Coaster Ever was the name Phineas and Ferb gave to their roller coaster in the first episode. Like the name suggests, it was a huge roller coaster that went around the whole city. After Perry the Platypus accidentally lifts the coaster in the air, it goes off coarse and into places like:
 * Mount Rushmore


 * Paris


 * A Mr. Slushy Burger


 * Outer space, by a satellite

It was rode on by the neighborhood kids, and at the end, it crashed into the tree in the backyard, setting it on fire. ("Rollercoaster")
