A Fourth of July special. Phineas is sick, so everyone wants to create a great fireworks display dedicated to Phineas. Doof hates fireworks because they're loud and always blinds him while he sits in his room. He creates a Deplosion-inator to cancel out every explosion by the fireworks, ruining everyone's Fourth of July and giving him a good day of rest. Older Phineas comes to the past to video tape the fireworks and his friends so he can show it to his children in the future. Young and older Phineas chat, but nothing big is revealed about the future. Young Issabella stalks older Phineas and constantly asks him questions. She plans to follow him to the future and see if she marries him. In the end Perry kicks Doof's butt, Phineas sees the fireworks display dedicated to him, [Insert Candace plot ending here], and after the fireworks Older Phineas goes to the Future not knowing about a sneaky Issabella catching a ride with him. Credits will show Issabella reappearing from the future with an extremely bright face, then the museum janitor will kick her out of the museum where she will see Phineas and Ferb as they are making their way to the museum to say good bye to future Phineas. They'll ask her where he is, and she'll say that he already went back to the future and then run off to home. Phineas says that she looked excited. Ferb will then comment on how she was following the future Phineas the whole time. Phineas will comment on how what she did was weird.
