Easter Sunday, the grand opening of the New Old Abandoned Amusement Park & another mission as well...
Perry, realizing today is the day to thwart Doof in another sinister plan, gets up & pushes a small red button on Phineas's bed, making the entire bed flip clockwise to a tube, sending his semi-aquatic body to his lair underground. Fedora is placed on his head as he receives the Major on the screen.
"Good morning, Agent P. Hope you enjoyed your vacation. You deserved it. Getting back to business, throughout your vacation, we were unable to get any information about Doof's new -inator. We montiored him the entire time until now. As he said, he's on his way to the beach...but all he's brought with him is beach things. Something very fishy is going on here. You know what to do. Good luck, Agent P." With a salute, Perry's chair springs him into the air, and his aircraft catches him as he blasts away to the beach.
Two familiar people reappear at the New Old Abandoned Amusement Park...with one Phineas & one Isabella awaiting their arrival.
"Hi, guys," Alyssa said.
"Hey, guys. We need to talk." Phineas said.
"Sure. Ok." Alex agreed.
"Where did you say you guys came from?"
"Danville, of course." Alex answered truthfully.
"We have thrown some of the biggest events that ever hit this town, but we don't remember you guys being in even ONE event until now..."
"We wanted to, but our parents wouldn't let us," Alyssa answered.
"There's something you guys are not telling us..." Isabella said, sensing it.
"..." Isabella walks to Alyssa, who has her head down in shame.
"Tell us." Isabella said, touching Alyssa shoulder. Then Isabella gets the same feeling as before. "...We're close...aren't we?"
"..." Alyssa says nothing. Isabella holds both of her shoulders now.
"I can feel it...it's like I've known you all your life," she continued. "Alyssa, look at me." Alyssa hesitates but looks up at Isabella. "You...you're my..." Alyssa starts to cry.
"...Mom!" She shouted, holding Isabella.
"Aww...it's ok, Alyssa." Isabella said consoling her daughter. "Was that so hard?" She pulls away and then looks at Alex. "That makes you my son, right?"
"Yes." Alex answered.
"So who is ur father, guys?" Isabella asked, wanting to be sure it is who she believes it is. Silence for a few minutes.
Meanwhile, at the beach...
***Doofenshmirtz on his vacation!***
Agent P lands next to his nemesis.
"Ah, Perry the Platypus...wait, why are you here? It's Spring Break! I don't do anything evil on Spring Break...oh, let me guess, Major Monogram, right?" Perry looks...disappointed?
"I'm sorry, Perry the Platypus, but I'm not doing anything evil today...Major Monogram must've been mistaken." Perry presses a button on his watch, emitting a hallographic picture of the Major.
"Agent P, it would appear that Doofenshmirtz indeed has no evil intention today. We're not perfect, Agent P. We apologize for the inconvenience."
"Well, since you're here, Perry the Platypus, why not take a load off?" Doof asked. Perry thinks for a second, then puts on his shades. "There we go."
"...It's-" Just as Alyssa was about to answer, Candace & Jeremy arrives at the Park.
"You guys are so...wow," She said marvelling at the sight before her.
"Admission is free, guys," Phineas said happily. Go on in. Just know that because we are using solar panels to power up all the rides, the Park will close 10 minutes before the sun sets, so that'll be at 6:37 exactly, ok?"
"We got it." Jeremy answered grabbing his girlfriend's hand. "Ready?"
"Yep."
"Now, you were saying, Alyssa?" Isabella said, getting back on subject.
"It's-" Again, Alyssa is interrupted...this time by two figures appearing behind them. It's...
"Oh...my...gosh!" Isabella nor Phineas could believe their eyes.
"Dad!" Alex said.
"Uncle!" Alyssa said, both seeing them appear behind them.
"Well, lookie here." One of them said. "Wow, I was so short..." Phineas walks up to the figure.
"You're me...from the future?"
"Yep." He answered. "And you already know who this is..."
"Ferb! Wow..."
"We just came to relive this moment...and to take them back home."
"Aww," The siblings said.
"Your mother misses you guys very much," Adult Ferb spoke.
"Yea. He's still not much of a talker..." Adult Phineas said.
"That's our Ferb. By the way, he seems to be having fun with Vanessa." They watch Ferb & Vanessa on the rollercoaster. Alex looks at his Ferb & gives him a thumb up. Ferb returns the gesture.
"All right, guys. It's time to go."
"Bye guys," Alex said, hugging them both.
"Bye." Alyssa starts to cry again. Isabella holds her again. "Mom..."
"Shh...it's ok...go on now. Your mother misses you." Isabella said, beginning to cry herself. Alyssa goes to Phineas and hugs him.
"There there." He said.
"Bye...dad." Phineas pulls away, shocked to hear that word. She goes to her family & they all vanish. Phineas looks at Isabella.
"Phineas...are you ok?" Isabella said to him, slightly blushing at how his eyes are staring at her. Phineas breaks out of the trance.
"Yeah. Let's go have some fun!" He grabs her hand, making her blush more. Then the two ran into the Park.
The End
