Rollercoaster: The Musical!

In this musical, Phineas and Ferb revisit the day they built their gigantic rollercoaster. Using a combination of music, song and dance, Phineas and Ferb build a rollercoaster in their backyard, Candace tries to bust them by getting their mom to return from the grocery store early, and Dr. Doofenshmirtz attempts to pull the Eastern Seaboard to the west using tinfoil and a giant magnet.
