After the curtain call on the last day of summer Perry walked up to Phineas, Ferb, Isabella, Buford, Baljeet, Candace, The Fireside Girls, Jeremy, and Stacey and took them down to his lair and put up images of the 2nd Dimension adventure. They all said except Perry, they remember after seeing the pictures. They all remembered about the trip to the 2nd Dimension. Phineas, Ferb, and Perry we're in Phineas and Ferb's room, Phineas was asking Perry if they can go on missions with Perry. Perry asked Major Monogram. Major Monogram said yes. Phineas, Ferb, and Perry did a group hug. So they planned their mission. So the plan was Phineas and Ferb go to school in the morning and after they go to school then they will go on the mission with Perry and then build something with Perry for the first time. So all three of them went to sleep. After Phineas and Ferb's first day of school they went up to their bedroom and told Perry they we're ready for their mission. So they all three went to Rodney's and all three of them got trapped. Perry got all three of them out of the trap. And all three of them fought Rodney. Then after when all three of them defeated Rodney. Phineas, Ferb, and Perry went home and started thinking about what to build. Phineas said guys I know what we're gonna do today. We're gonna make an iPad for Perry and Pinky. and we're also gonna make a water slide so Phineas, Ferb, and Perry started making a water slide and the iPads. After they were finish. Isabella, Buford, and Baljeet walked in, Isabella said, what'cha doin? Phineas told her, we just finished making an iPad for Perry and Pinky so we can understand what there saying. Phineas gave the iPad to Perry. Isabella ran over to her house and got Pinky and ran back over to Phineas and Ferb's house and gave Pinky the iPad and explained about how he was gonna use it. Perry and Pinky both texted hi. The kids all cheered because iPads worked. So they all went on the water slide. Isabella, Phineas, and Ferb were especially excited about the animal translators worked because now they get to text to their pets about all there secret agent missions they went on. They all went in the tube to go on the water slide. Candace came out and climbed up and the ladder to talk to Phineas. You already made a water slide. Phineas said, I know we wanted to do one again but bigger. Candace was about to go down the ladder. Then she slipped and went in the tube. They all went down the water slide. They all were having fun except Candace. Candace was screaming. Once they got down the water slide Candace said, I'm telling mom. They all went up the ladder except Candace and went on the water slide 5 more times.
