Minor Monogram

That's my boy!

With Fall around the corner, Phineas and Ferb decide to invent "S'Fall," a colorful world full of giant leaf piles and gourds. Meanwhile, over at Evil Inc., Dr. Doofenshmirtz is mentoring Rodrigo, a budding student of evil. Unfortunately, Rodrigo truly is evil, and when he captures Dr. Doofenshmirtz and Agent P., it’s up to Major Monogram's son, Monty, to save the day.

Episode Summary
Phineas says that summer seems to be going very fast, and Isabella states that fall starts shortly. Baljeet cheers because of school arriving, but realizes quickly that the others were commenting negatively. Phineas thinks that fall has good qualities and knows what they are going to do today. Phineas remembers when they made S'Winter, so they start making S'Fall and then asked where Perry is.

In Perry's lair, Major Monogram tells Carl that he was the son he never had. Carl happily questions him and Monogram says that it's because Carl is nothing like the son he's already had. Then Monty Monogram enters to screen and salutes Agent P, who had already met off-screen. Monogram proudly says his son has graduated from the High School Without a Cool Acronym, and Monty waits to fight evil like his father, although Monogram explains him that he always wanted to be an acrobat. Carl says he'd be willing to be an acrobat to impress Monogram. As they walk off screen, Monogram tells Agent P to go stop Doofenshmirtz.

At Doofenshmirtz Evil, Inc., Vanessa finishes a fight with her boyfriend Johnny over the phone, and sees her father with Rodrigo, a student at evil science school whom Doof is mentoring in the art of evil. Immediately after being introduced to Vanessa, Rodrigo begins flirting with her, to which Vanessa responds positively to. Doof, noticing something wrong with his daughter, asks what's wrong with her. After Vanessa explains her break-up, Doof remarks that she usually goes for the bad boy types. Vanessa responds by saying that Doof is evil himself, though Doof explains that there is good evil and bad evil. Rodrigo cheers Vanessa up by making a face at Doof while she is hugging him.

Back at Phineas and Ferb's backyard, Baljeet wonders how they're supposed to get the leaves down. Buford hands him one handle of a two-man saw, and tells Baljeet to cut down the tree in the yard. Isabella stops them from doing it, because the tree had been the starting point of all their adventures that summer. Phineas takes the opportunity to showcase their newest invention, a rapid leaf production accelerator. The accelerator is a device that ages the leaves on a sapling tree so that they change color and fall off, making way for new leaves, all in a few second. Ferb lets the machine go wild, filling the yard with leaves within minutes. Meanwhile, Candace is talking to Stacy on the phone, when she sees the leaves pressing up to the sliding door. Thinking that Phineas and Ferb had covered the door in leaves to prevent her from seeing what they were building, she tears the door open, only to see that the leaves are forming a wall against the door. She digs her way into the giant leaf pile, which we see is many times the size of the house.

Doofenshmirtz is giving a lecture to Rodrigo on the value of a villain's back-story, breaking off and throwing his pointing rod in the process. Vanessa asks to have the roof of the building put down, to which Doof obliges. While Vanessa rains compliments on her father, Doof interrupts to say that she will not be getting a tattoo, which was what Vanessa was working up to. As soon as the roof is retracted, Agent P para-glides in, only to be trapped inside a boot that Doof says he modeled off of Vanessa's "vampire pilgrim scuba-diver" fashion. Rodrigo protests that Agent P would easily escape from the trap, though Doof protests that the trap only needs to hold Agent P until the end of his monologue. Willing to prove himself, Rodrigo volunteers to demonstrate his own trap-making abilities. While he constructs a new trap for Agent P, Rodrigo reveals he plans on getting rid of both Agent P, and Doctor Doofenshmirtz.

In a balloon rising over the leaf pile, Phineas explains that the sweet spot for jumping in the pile is right at the top, and Buford passes out his hand-made gourd helmets, which he says captures the person's essence. The kids then jump into the leaf pile, which actually seems to be hollow on the inside, and has a giant slide. Candace digs out to the other side, and wonders what the boys are doing today, convinced that they're hiding their project inside the leaf pile.

With Agent P's new trap constructed, Doof asks how he feels, and seems to respond to Agent P's miming and chatters. Rodrigo asks if Doof can actually understand Agent P, but Doof says he just pretends Perry's talking about movies. Vanessa asks if Doof made a left boot-trap, and he responds that a left boot-trap would be silly, as Agent P presses an emergency alert button on his watch. At O.W.C.A. Headquarters, Monty sees the emergency alert, but his father and Carl are too busy doing acrobatics to notice, so Monty takes matters into his own hands, and runs over to Doofenshmirtz Evil, Inc.

Doofenshmirtz unveils his new plan, to use two gigantic propellers to lift the Tri-State Area into the air, and hold it ransom until he is made leader (after running some errands). After the propellers are activated, Rodrigo reveals his true colors and uses a special hidden trap inside Agent P's to bind Doof's legs. Vanessa attempts to help, but discovers her right boot-trap is secured to the floor. Rodrigo explains that his plan is to use Doof's propellers to tear the Tri-State Area apart. When Doof asks what Rodrigo plans to rule when the Tri-State Area is destroyed, Rodrigo announces his intention to rule the world. Doof responds by saying that ruling the world is almost as crazy as making a left boot-trap. When Vanessa reminds her father that making matching boots is normal, Rodrigo asks Vanessa to rule the world at his side, to which she refuses. Unperturbed, Rodrigo proceeds with his plan to destroy the Tri-State Area, only to be tackled to the ground by a jet pack-wearing Monty. Monty then uses Doof's pointing rod and some spare rope to make a trapeze over the propeller control tower, easily knocking Rodrigo around. Agent P uses his communication watch to show Major Monogram how his son uses acrobatics to fight evil, and Vanessa frees Agent P from the trap.

Phineas, Ferb, Isabella, Baljeet, and Buford are sitting in the leaf pile, eating candy apples, when Candace slides down towards them screaming. As she passes Buford, he gives her a gourd helmet. Candace announces that she's busted them for sure this time, but realizes that sitting down eating candy apples isn't something she can bust them for, and Phineas offers her one.

Doof frees himself from his own trap and proceeds to carry out his own plan, carrying the Tri-State Area up, but Agent P swiftly thwarts him, and the Tri-State Area slams down to the ground, causing the kids' leaf pile to spread out among the neighborhood, though the leaves can still be seen. When Candace goes inside to get Linda to look outside, one of the propellers falls over, fanning the leaves away. When Linda gets outside, she notices that the kids already have their own snacks, and says that her work there is done. Ferb asks everyone if they're ready for "sprummer".

Monty finishes tying up Rodrigo, and tells Agent P that he can take it from there, as Agent P finishes restraining Doofenshmirtz. Rodrigo tells Vanessa that he thought she liked "bad boys", but Vanessa says that she wants to try a good guy, as she stares at Monty flying away on his jet pack. Agent P walks up and notices her looking at Monty, and is shocked.
