Rollercoaster: The Musical!

You know, Ferb. One of the best times we ever had was when we build that rollercoaster. We should do it again, but this time as a Musical.

In this musical, Phineas and Ferb revisit the day they built their gigantic rollercoaster. Using a combination of music, songs 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.
