Phineas and Ferb

Jerk De Soleil

Phineas and Ferb are excited to go to the traveling acrobatic cirque show. But when it gets canceled, they decide to put on their own show for the entire neighborhood instead. They enlist all the kids -- even Buford -- to take part. Candace tries to stop them as... more usual, but her allergic reaction to parsnips turns her into a deep-voiced blues-singer with a bag on her head, and she ends up becoming the hit of the circus. Meanwhile Dr. D tries to use the Voice-inator to make everyone's voices higher so his seems lower, on "Phineas and Ferb."
