Episode Summary
One day, Erin is jamming to some country music, when her mom gives Erin a pile of boxes. Erin questions the boxes. Her mom says they're moving to a new town. Erin wonders why. It's because her father couldn't keep up with the house payments. Erin has tears welting up in her eyes. She begins to pack. Once she's done, she texts Haven about her departure. Haven rushes to Phineas and Ferb's house once she hears the news. Phineas couldn't believe what he just heard. He thinks they should throw a party for her. But then, Perry is missing and Phineas thinks Perry would want to join the festivities. Perry is off on an exciting mission. He enters his lair through a basket. Monogram tells Perry that Doof has been all over today, and they aren't sure of his exact location. They need Perry to locate him and bring him back to HQ. Perry rockets off in his jetpack, as usual. Meanwhile, Erin is walking around town, seeing everything for the last time. Suddenly, she sees something odd going on at Phineas and Ferb's house. Meanwhile, Perry is on a mad chase for Doof. He chases him everywhere and anywhere. They end up going all over the world. The party for Erin goes well, and Doof is captured, but he breaks away.
