Episode 1: Flashback
Phineas and Ferb, 6 and 5 years old, are sitting in the living room and are bored. Then Linda, their mum, comes in and says "Kids, we are going to get you a pet!" "Oh, great, a pet!" Phineas says excited. "Then come on" Lawrence says coming "The shop is open already, and its very popular!" The kids are running out, the parents cant follow so fast. Candace comes with them, too. As they are arriving at the pet shop, they looked at every pet. Mum: "This is looking at you, Phineas!" Dad: "And this one is looking at you, Ferb!" Candace: "Why wont anything look at me?" Then Phineas and Ferb are finding the perfect pet. Phineas says: "This looks at both of us at the same time!" "krkrkrkrkr!" Candace don't trust the pet: "How will you even name a platypus?" Then Phineas and Ferb are saying: "Perry!" "krkrkrkrkr" "Well, fine" Candace says.
At home they want to play with Perry exactly now, but: "Hey, where IS Perry?"
Perry is in his new lair. Major Monogram is appearing on the screen: "Good morning, new Agent! You are now Agent P and will get a hat!" And with that Agent P gets a hat. "We decided for Dr. Heinz Doofenshmirtz as your enemy! At the moment he builds an army of robots! Your mission is to stop him!" Agent P salutes and arrives less later. "Ah, my new enemy, Perry the platypus!" Doofenshmirtz, with an eyepatch, says. "Do you see this robots?" "krkrkrkrkr!" "Well, that's the last you will see as a normal platypus!" Then a cyborg maker machine falls down before Perry and sucks him in. "Goodbye, Perry the platypus, hello, Perry the platyborg, general of my army! Muhahahaha!"
In the pet shop, Isabella arrives with her mum. Her mum looked around: "uuuhh! What about that one? Or that one? Or this? Or…?" Isabella is about to choose a Chihuahua, as robots are arriving in the shop saying: "Doofenshmirtz is your new leader! Put your Dooferalls on!" Everyone is in panic, Phineas and Ferb are seeing the chaos from the inside of their house. "What happened?" he asks his brother, but he just shruggs his shoulders. Then a few robots are flying inside their house saying: "Put you Dooferalls on!" "Y-Y-Y-Yes, of course" Phineas says scared. Candace hides and decides to protect her brothers of this robots so she will get as much people as possible together to found a resistance.
Five minutes later the Tri-State Area is full under control by Doofenshmirtz and his general platyborg, Phineas and Ferb are so scared that they are just playing the new game Doofopoly. Candace in the meantime got some people together: Isabella from the pet shop with her fireside girls, renamed firestorm girls, Buford, who likes resisting and is also really good at it, Baljeet, a very smart guy, Jeremy Johnson and other people. "So lets kick some robots to nowhere!" Candace shouts. "Without HQ?" Baljeet asks. "Good thinking" Candace says, but from where do we get this?" Then a door in the wall opens. "What is this?" Isabella asks. All are confused. "I would say, just looking" Buford comes with a very simple idea. They get in the wall elevator and arrive in Perrys lair. "I think we have our HQ" Candace says.
Today they found even Pinkys lair, or what used to be Pinkys lair, and connected it to the today black HQ.
And this is where it starts…
