Phineas and Ferb: Split Personality/Brain Drain

Candace switches places with a princess who looks just like her but the ongoing antics of Phineas and Ferb prevent her from enjoying the royal luxuries, even for a day.

Just as Linda returns home to confirm her suspicions, the entire party mysteriously moves to another location and Dr. Doofenshmirtz's go away-inator may be involved. Sophia Bush guest stars as Sara.
