As Phineas, Ferb, Isabella, Buford, and Baljeet headed over to their new friends' house, Phineas has one question he had has to say. "Hey, where's Perry?" he asked.
The next scene takes place with Perry's secret lair that looks exactly like the one he had in Denville, with him sitting in his chair, looking at the screen where Major Monogram's head appears. "Good Morning Agent P, I hope you don't mind that we made an exact copy of the lair. We wanted to make more custom to your new surrounding, but you know, budget. Anyway, we just received intel that Dr. Doofenshmirtz has just purchased a large number of building materials such as lumber, concrete, and painting supplies. Either he making homes voluntary or he building something that is related to evil. It's up to you to find out what he's up to and put an end to it." he finishes saying to Perry. Perry saluted to him and headed out to stop Doofenshmirtz.
The gang made their way across the street and stood right in front of the home of the Dalmatian Family. "Before I open the door, I need to warn you all that my pups can be a little 'friendly' when new people arrived at our home," Delilah warns the children. "If they're anything like you, Dylan, Dolly, and Mr. Dalmatian, I sure that we can get along just fine, Mrs. Dalmatian," Phineas said with a smile. Delilah smiled at him not just because of his friendly personality to her and her family, but his formality in using 'Mr.' and 'Mrs.' instead of using their first names shows how she can respect and trust him. After their little conversation, Delilah places her paw on the scanner, which allows the door to unlock and open for them, which in seconds revealed a huge amount of puppy dalmatians standing right in the door, jumping up and down while chanting 'new neighbors'. "That's a lot of dogs," Baljeet said.
"Now that we're all here, let us introduce you to our family," Delilah said. "As you all aware my name is Delilah and I work as a nurse at a near hospital. My husband Doug works as a fire dog. Dylan here wants to be the first dog on Mars," Delilah continues to introduce the family. "That cool, maybe we can take you there this summer," Phineas said the Dylan. "The way you said that sounds like you already been there," Dylan said with a little chuckle. "We have," Phineas said as Ferb took out two pictures with one of them show them riding on a custom-built rover vehicle while the other shows them being chased by a giant martian, which cause Dylan's mouth the gape wide open for not only meeting people who have been to Mars but that there were actual Martians, which cause Dolly to laugh at her brother's expression. "Dolly here loves to skateboard," Delilah said, "Cool, maybe we could go skating together," Phineas said to Dolly. "I would like that," Dolly said to him as she usually doesn't get along with humans well, but something about these kids seems to put her nerves at ease. "Next we have Dawkins help us around the house by inventing many gadgets, including the door scanner," Dawkins walks closer to the kids. "May I ask you how can you communicate with us," Dawkins asks. "We made universal translator earbuds," Phineas said pointed to his ear. "Fascinating," Dawkins said with stars in his eyes. "Da Vinci here is quite the artist," Delilah said as Da Vinci introduces a new painting that was splash, smear, and had a couple of paw prints on them. "Contemporary Abstract Painting?" Ferb said, which was replied with a thumbs up by Da Vinci. "D.J. is the musician of the family," D.J. played his keyboard instead of talking, which leads to Ferb taking out his keytar and play in response. "Here you can see Deepak meditating on the couch," Delilah said as Deepak was meditating with his eyes closed and humming. Baljeet walks up next to him and waves his arm in front of his face for a response, but there was none. "So focus, so deep into his mind, so peaceful, it like I'm looking at a canine version of me," Baljeet said. That was when the Dimitri trio came out of nowhere and start barking at Deepak, which causes him to leap out of the couch and fall face-first on the floor, which cause the Dimitri trio to laugh at him, which also made Buford smile at their antics. "I like the way these pups think," Buford said. "I see you already met the Dimitri trio," Delilah said as the trio was still laughing at Deepak. "Speaking of trios," that's when Destiny, Dallas, and Deja Vu leap out in front of the kids doing some poses. "These are…" Delilah begins to speak "The Triple D!" Isabella ended. "Do you know them, Isabella?" Phineas asked. "Pinky's a huge fan of them," Isabelle said taking out a photo with Pinky wearing a Triple D hat, shirt and surrounded by Triple D's brand merchandise. "Can I get an autograph for PInky?" Isabella said bending down so that she can show the picture to Triple D. "Anything…" Destiny begins to speak as she places her paw to make an autograph paw print of the photo. "..for a…" Dallas said next as she places her paw after Destiny. "...fan overseas," Deja Vu finishes the sentence with her being the last one to place her paw on the photo, which shows three pink paw prints. As Triple D finishes with their paw prints, the ground begins to shake, and before anyone can say what was going on, a hole appears on the floor and what came out was a pup cover in mud and had a unibrow. "The one who just made a hole in the floor is Diesel," Delilah said with an annoyed look on her face. "Maybe he likes to help us dig to the center of the earth," Phineas suggested. "I can dig it," Diesel said followed by him going back into the hole. Before Delilah can introduce the next pup, a blur zoom around the house, and when it came to a halt, the children can a pup who was in a doggy wheelchair. "This is Degado," Delilah introduce him to the kid. "Nice set of wheels. Maybe we can race someday," Phineas said to Delgado. "That sounds awesome," Delgado said as he zoomed out of the room. "Over there we have Dante," Delilah pointed to him, which surprised the gang at they had never seen a full black fur, white and purple-spotted dalmatian before. "Have you ever face terror before?" Dante asks the gang. "We made a haunted house'" Phineas said. "That acceptable," that was all Dante had to say to them. "Next up are Dizzy and Dee Dee," Delilah said as two young pups run over to them as their tail wags rapidly. "It'll be fun if you'll come to play with us," Dizzy said. "Yeah! Every day!" Dee Dee added. "Oh! You two are the cutest things!" Isabella said as she kneels to give the two puppies a hug, which they appreciated. "And lastly you already know Dorothy," Delilah said as the youngest pup was on Doug's head chewing on a toy bone while giggling.
"Wow! So many pups with many different personalities. I bet every day is an adventure to you guys," Phineas said. "It would be even better if we can go on vacation," Dolly sadly said. "You mean you guys don't have anywhere fun to go?" Phineas asks them, which causes most of the dalmatians to have sad, puppy faces, lowering their heads, and whimpers a little bit. "That so sad'" Isabella said feeling their sympathy. "Well what can we do, it's not like we can have a vacation in our backyard," Doug said. That's when Phineas has his idea. "Ferb, are you thinking what I'm thinking?" Ferb took out a blueprint and show it to Phineas. "Once again you read my mind," Phineas said.
The next scene takes place in London where an exactly, looking building of Doofenshmirtz Evil Incorporated can be seen, except that thing building had the words "London Branch" written underneath it. Perry enters the building by kicking the window and land into the lair, but unfortunately for him, a platypus-size brick house landed on top of him, trapping him. "Ah, Perry the Platypus, how do you like the lair? I know you're thinking about why it looks exactly the same as Danville. It's kinda like using the bathroom: it doesn't feel right unless it's your own. And that is what I build the this!" Doofenshmirtz reveals a large ray gun. "The Decorator-Inator! Before I left the country, I legally purchased my very own cabin which gives me ownership rights. If I use my Inator on Buckingham Palace and transform it into my cabin, it will be rightfully mine, to which it will automatically make me ruler of all of England! And best of all I didn't need to pay a cent to make this bad boy, because thanks to last summer's pharmacist trend, I was able to sell the rights to a black and white hair billionaire woman. I think her name was Estella or something like that. Anyway, in a few minutes after my Inator is fully charged, all of England will be mine!" Doofenshmirtz said with an evil laugh.
Back to Phineas and Ferb's group, Phineas was talking to a delivery guy. "Alright, that ten tons of concrete, wood, brick, steel, metal, timber, cement, concrete masonry, and clay. Say, aren't you a little young to construct a five-star summer home?" the delivery guy said to Phineas. "Yes, yes I am," Phineas said to the delivery man. The delivery look at Phineas for a second before saying "Well as long as you have your permits," he said as he left. "Is everybody ready?" Phineas said to his friends who he receives multiple agreements and happy barking as they were wearing construction hats. "Then let's get to work!" he said.
The next scene takes place in the new home of Flynn-Fletcher's new summer home as Candance was sitting in the chair with her cellphone place next to her as she was having a conversation with Stacey. "And I was like "You better listen to me or else!" and they were silent in shock and I said "That's what I thought," and then..." before she could continue to talk, she heard large construction sounds coming from across the street. "I have to call you back Stacy," Candace said with an annoyed look on her face. "My busting instincts tell me that Phineas and Ferb are behind these noises," Candace said as she walks outside and headed across the street.
Meanwhile at 103 Dalmatian Street, Clarissa was taking a nap while her human was out. All of the sudden, a loud noise woke her up, which cause her to growl. "There only one ruffian family to make that much noise," she said as she headed out to find out what the dalmatian family is up to.
