The I teams (except Aggie) were strolling along the street, chatting about keeping the agent secret. Suddenly, they saw Perry and Pelry in agent mode, who were lift a tree by the bottom of its trunk and enter their lair. They all know that Perry and Pelry are having a mission with their nemesis, Doofenshmirtz and Doofai. So they decided spy on them using invisibility to past through halls of the agents' lair and no one will notice them that they're watching. When the teams pass through the ground secretly enter Perry and Pelry and become invisible, they start to spy and listen to what the agents' next assignment.
Major Monogram and Major Monogrey appear in Perry's screen. "Good morning Agent P and GuardianAgent P" Monogram greeted them. "It seems like Doofensmirtz and Doofai were spying on restaurants all morning". "It must be they planning something on restaurant food" Monogrey said continuously. Then Monogram tells Perry and Pelry to go to the DEI and find out what the Doofs are up to. But Perry and Pelry glance at each out and get the feeling that there's something or someone's missing. Perry was about to say something but it was interrupt by Monogram "Don't worry Agent P. Agent AG will come too. Of course, she takes a break a month ago, but she'll be back. I think she'll be arriving late because of her travel" Monogram finished as he sniffs. He already misses Agent AG although, she only have been gone for a month. Monogrey pats his ward to make him feel better and says to the two agents' "Just go and stop the Doofs" as he continues patting Monogram. When Perry wears his jet pack and blast off out of his lair, while Pelry followed him. While their gone, It's the I teams chance to become visible again since no one is around. Some of the members wonder who is Agent AG"
"Agent AG?" Turbo asks.
"W-w-w-who is A-a-agent AG?" Piglet said nervously
"Agent AG is a she?" Yan questioned
"Is she a human or an animal?" Maltor also questioned.
"Sounds like Agent AG is more popular than Perry or Pelry. Did you see the look of Monogram's face?" Miley said sarcastically.
"It's quite so. AG is kind of familiar to me" Jack thought so.
"Me too" Jet said.
"Me three" Discord thought about it too.
"And me" Twilight also thought that too while raising her hoof.
"It doesn't matter!" Olive interrupts them loudly. "We need to follow Perry and Pelry before we lost them and we're gonna miss a plan and a fight scene"
All of her fellow members starred at her know that there's something she didn't mentioned. "And find out who is Agent AG at the same time" Olive continuously said. The I teams shrugged and ready to go. They plan first to follow them secretly (Perry and Pelry don't want their friends to join them on their mission because the agency planted hundreds of hidden cameras in Doofenshmirtz Evil Incorporated). The winged-members of the teams start to flap their wings while Izzy, Tinkerbell and Periwinkle use their pixie dust to make their flightless members fly. When they start following Perry and Pelry, Pelry suddenly felt a sudden disturbance in the force that somebody is following them (which Pelry was already trained from the Jedi order by Obi-wan Kenobi). The I teams quickly use their invisibility power to become invisible. Pelry then immediately ignores it and proceed following Perry. The I teams sigh in relief, become visible again and continuously follow Perry and Pelry and tries to figure out who is Agent AG that Monogram mentioned. When Cosmo and Cos sniff some bacon strips, they swiftly flew down. Then Rico smells a basket of fish, He swiftly flew down also, with Renda, Reco and Rida following him. And Fred spots a plate of fries from a fast-food restaurant; he also flew down in happiness. Skipper scoffs and tells his fellow members "there's no time for snack!" But he saw all of his fellow members, including his wife and kids, were starving, especially himself. "Alright. Let's go take a break for a while." Skipper said frustatedly and all of the members cheered in a whispery sound. The I teams fly down slowly to go eat.
Agent P and GuardianAgent P finally arrives at DEI and immediately get trapped in a giant sandwich. Doofenshmirtz and Doofai explain to their nemeses about their new scheme. "Earlier this morning, we saw people of Danville walking to many restaurants. We wonder why they have to order food. There's so many frozen at the grocery. Now we know why, because they have their own favorite dishes which they don't know how to make them for themselves. Then it gives me an idea, if we build an inator that can take the dish from a restaurant and teleport it to here, it can make a copy of this dish and the people who love this will go to our building. Then all of the restaurants in Danville will close, we can build our own restaurant, and the people will go to ours, Heinz Doofenshmirtz and Heinza Doofai's very own restaurant." narrated Doofenshmirtz. "In order to do that, we created this," Doofai throws a blanket that covers the inator "Behold! The Steal-and-copy-the-food-inator! It can steal any food from a restaurant and copy exactly like it. When our restaurant is very popular, and the both of us are popular, we will become the mayor of the ENTIRE TRI-STATE AREA!" Doofenshmirtz continuously explain. As Doofenshmirtz and Doofai push the Steal-and-copy-the-food-inator out of the room to the balcony, Perry and Pelry realize that they are trap in an edible giant sandwich. So they eat the sandwich to free themselves.
Meanwhile, the I teams were already finish eating their food and decided to catch up watching Perry and Pelry fighting their nemeses and find out who is Agent AG. The I teams fly upward and reach the edge of the balcony of the building. The I teams were in-time to secretly watch the fight. But they got the feeling that something's missing. When Perry was about to attack Doofenshmirtz, Doof pushes Perry and accidentally slams into the fire button on the inator. The inator was about to fire until suddenly, a small explosion seen at Doofenshmirtz's door and throws a brown fedora with a small pink bow on the middle to the fire button to turn the inator off. The I teams expect that it was a mysterious Agent AG. The smoke from the explosion fades away and the hat was caught by the fingers of… could it be? "Hello Doofenshmirtz and Doofai. Long time no see. And sorry I'm late." Agent AG said as it turns out to be Aggie (which her first-two letters of her name and her full name, Agatha Galido, are the meaning of AG) putting her hat on her head and ready for a combat fight. I teams were shocked in surprise saying "Aggie is Agent AG!"
"Oh my gosh! Our leader is a secret agent from OWCA. My mind is officially blown" Lola said as she was thrilled to see her real friend/leader in an agent mode. "Aw, come on, we knew it all along" Jet interrupts her sarcastically. Then Red pushes Lola and Jet aside to look in a better view to see his girlfriend and said to his friends "I really want to marry her right now". "You know Aggie is still very young to get married" corrected Blossom. "So what?!" Red said angrily as he leaned to blossom showing his angry face. The I teams stop the conversation and watch Aggie's new agent moves in awe from outside.
Aggie does her triple back flip and land safely on the ground, pushing Doofenshmirtz out from the inator. "Amazing" Private said as he was amazed of Aggie's movies.
When Doofai grabs her wing, Aggie uses her other wing to remove Doofai from her wing. "Incredible" Fluttershy whispered as she was amazed of her wings can bend like a plastic, unlike other insects with wing like her (ex. dragonfly, bee, her fairy sisters).
Then Aggie jumps on top of Doofenshmirtz to cover his eyes with her shoes. Doofai was trying to help his ward but he got trap ny Pelry and her pink untied ribbon. When Aggie almost loses her balance to cover Doofenshmirtz's eyes, Perry quickly pushes a computer chair. When it comes closer to Doofenshmirtz, Aggie quickly jumps off so that she will not fall too, then Doofenshmirtz fell down.
"Impossible!' Skipper said surprisingly. "Aggie never used those moves when we have training or a battle. She didn't even use her powers."
"Or the Force too." Luke continuously said.
"Too late Perry the Platypus, Pelry the GuardianPlatypus and Agatha Galido" shouted Doofenshmirtz as he crippled to the Steal-and-copy-the-food-inator and he pushes the on button to fire "we're going to steal the food from the restaurants randomly!" When Pelry was distracted by this scene, Doofai punches her to free himself from Pelry's trap. When the inator was about to fire, the I teams hide their heads so that they will not get hit by the inator. As the inator fires randomly, the food that hit appears behind Doofenshmirtz and Doofai. Doofai takes a piece of Cremeschnitte and tosses it his nemeses. Pelry protects Perry, Aggie and herself by bringing out her two knives and slice them into pieces. Then Doofenshmirtz tosses Accasciato. Perry quickly opens a drawer and gets out a cheese grater. He leaps forward and grates the cheese to block the hit. Then both Doofensmirtz and Doofai throw a bowl of mash potato. Aggie doesn't know what to do to protect Perry and Pelry from being hit by mash potato. So Aggie took a spoon and jumps to catch the bowl and eat the mash potato. While Doofenshmirtz and Doofai were distracted by complementing that they forgot Aggie loves mash potato, Perry and Pelry kicks the Doofs down and Aggie gets a rope of sausages and ties them tightly so that they will not escape. Before they go, Perry pushes the self-destruct button. To his, Pelry and Aggie's surprise nothing happens. He ponders for a moment and tries pressing again repeatedly. "Ha! Gotcha!" Doofensmirtz interrupted. "See, I began to think, 'If only I had a nickel for every time you pushed my inator's self-destruct button', and then it hit us. You guys wouldn't have nickels either because you don't have any pockets! Wait, wait, wait, what are you-?!" Perry takes off his fedora revealing a nickel on his head. "Oh, I forgot about your hat." Pelry takes out a nickel from her pocket "And she has pockets on her dress. I forgot about that. Doofai said frustratingly. Then Aggie takes out her own wallet and grab a nickel "And Agatha Galido has her own wallet?" questioned Doofensmirtz. Perry, Pelry and Aggie put their nickels in the slot and Perry push the self-destruct button. "Quickly hide!"Baby Brags warned his friends. As the I teams hide under the balcony, Perry uses his glider to glide out off the building while Pelry and Aggie fly out. As the inator explodes, Doofenshmirtz and Doofai realize that they can free themselves by eating the sausages. "Let's get out of here." Timmy whispered. Cosmo and Wanda raise their wands to poof them back to their HQ.
There are some parts of the chapter that I made it up. There are some others I on are just based on some episodes like "Mommy, can you hear me?" in Phineas and Ferb; when Perry and Doofenshmirtz were having a food fight and "Daring Don't" from My Little Pony Friends is Magic; where the mane 6 learns the author of Daring Do books, A.K. Yearling was actually Daring Do.
