Meanwhile, under the Flynn-Fletcher house...
"Good morning Agent P." Major Monogram said. "Doofenshmirtz has recently bought an enormous bunch of tools and supplies from various stores in Danville. We currently do not know what he is doing but it can't be good. We need you to find out what he is doing and stop him." Perry gave Major Monogram a salute before running to his scooter and driving off to the Doofenshmirtz Evil Incorporated building to stop his nemesis.
"Phineas! Have you seen my screwdriver?" "Yeah, here it is." "We need to fasten this bit, Ferb, can you handle it?" Ferb gave Donnie a thumbs up sign before going up to fasten a part of the portal. "Isabella! Can you screw that portal part tightly?" "Okie dokie!" Isabella agreed and ran off with a screwdriver. Despite the turtles being busy helping Donnie and the inventive children, they can't help marvel at the children's ability to invent and build. "Seriously guys, I have to say, you are doing an awesome job! Almost as good as Donnie!" "Thanks! You guys are doing great too!" Phineas yelled out loud as the loud machinery makes up most of the noise in the backyard. "I never knew there could be more Donnies in other dimensions!" Raph commented at the children's skills. Donnie grinned from ear to ear before referring to the blueprint of the T-Porter.
"Perry the Platypus, how completely unexpected! And by unexpected, I mean EXPECTED!" Doofenshmirtz said as he saw his teal nemesis. "And you have just fallen into my trap!" He pushed a button and a basket trap popped out from nowhere, trapping Perry. "You are also just in time to see my latest invention...The PORTALINATOR!" He took off a piece of cloth, revealing his invention. "You see, I have the idea that since I could not take control of the Tri-State Area, I can try to take control of other dimensions and build my own army. I can then use my newfound army to take control of the entire TRI-STATE AREA!" A streak of lightning suddenly flashed in the sky. "What's with the clouds and lightning?" Doofenshmirtz wondered.
"Anyway, let's see if the invention is working!" Doofenshmirtz immediately turned on the device and it sprung to life, right before their very eyes. "YES, it worked!" Doofenshmirtz cheered. Before he could savour on the taste of victory, a portal opened and some pink exoskeletons appeared.
"Kraang, where is the location which is known as this place?" "Kraang does not comprehend." The Kraang robots which swarmed in through the portal asked one another. "Hey, who are you guys? Why do you keep calling yourselves the Kraang all the time? You sound like a broken record!" Doofenshmirtz impatiently questioned. "We are the Kraang, and we will take over the planet which is known as the Earth. We will take over the Earth, by order of Kraang Prime." "Actually, I am trying to take over the Tri-State Area too!" Doofenshmirtz eagerly answered. "What is the name which is known as your name?"
"My name? Oh I am Dr Heinz Doofenshmirtz. This is my nemesis Perry the Platypus." "This is the animal which is known as a platypus which is also known as your enemy?" Doofenshmirtz answered, "Uh, yes?" The Kraang immediately blasted at the basket trap. It missed Perry, but it blew a hole in the basket trap. Perry immediately took the opportunity to escape. "Something called the Kraang is invading Danville together with Doofenshmirtz?" Perry wondered. "Not good, must report to Major Monogram via the widescreen monitor right away."
As Mikey was helping, he accidentally found a hatch below some grass. "Hey dudes, dudettes, check this hatch out!" Everyone immediately gathered to where Mikey is pointing. "Weird, I have never seen a hatch or trapdoor outside the backyard before." "Should we go explore it?" "I think we should. Come on!" Leo slided in first, followed by the others. "Woah...This is so, AWESOME!" Mikey shouted excitedly when he saw the cool settings in Perry's lair.
"Cool technology here! Did you do this Ferb?" Phineas asked his brother. "No." Ferb answered calmly. Donnie was amazed by the lair. "This place has tons of high-tech stuff that I can use!" Donnie said. "Are you sure you guys did not build this?" "No, no we didn't." Phineas answered. Just then, a teal platypus was making his way into the lair, preparing to report the matter to MM, when he suddenly saw the entire group there, in his lair. He looked at them with a mixture of amazement and bewilderment while they saw him, looking very shocked and surprised. "Perry?" Phineas said.
