It's unknown how they took the fort apart afterwards. |The idea of a fort was bought up Linda in the Original Pitch. It also looked like Big Ben from "Elementary My Dear Stacy" with the water slide. This was the first project that Candace made the boys do to compete with Thaddeus and Thor. |- |"De Plane! De Plane!" |[[File:Paper Pelican.jpg|center|180px]] |They built a huge airplane made of paper mache called the Paper Pelican. |It landed in water and dissolved. |Later on, When the Paper Pelican descended into the lake, it began to dissolve in the water because it is after all made of paper mache.

The Linda robot controlled by Garbog disappeared after he flied off. |In the end, Ferb was not an alien, and there were logical explanations for all of her proof. For example, Candace thought she saw Ferb's head floating in liquid in a jar, but the jar only contained the liquid and Ferb was standing behind it; and when Candace thought she saw Ferb's head ripped off, but she had mistaken him for a cord in a tent. |- |"Ain't No Kiddie Ride" |[[File:Ain't No Kiddie Ride.jpg|center|180px]] |Phineas and Ferb tricked out kiddie rides at a store. |The rides were taken away and replaced with brand new identical ones. |Candace ended up flying around town uncontrollably, and the boys and their friends had to save her.
