Phineas and Ferb: Across The 2nd Dimension

Your POV

Oh yeah!

After a bad bad thing that happened to my at Paris, I'm finally back at Danville.

I still can't believe that I met Ladybug and Chat Noir!

They are so cute together. Like they are so powerful.

Ok. Let me just think about the Last Days of Summer at Danville.

So, I think I only have 8 or 9 days left till I could get back to New York and have a new school to enroll at Paris.

I just wanna spend more days with all of them. But, summer is almost over. I can't just turn back the time and reverse all the bad things that happened to me this summer.

Well, all I do was sit still and look pretty today. I wonder what's in store for Phineas and Ferb's inventions.

And I peaked through the window. And I see them having fun with Perry. And they are like playing a Platyball Baseball game.

And Phineas suddenly rejoiced after he got a strike on Platyball Baseball. I'm so happy for him.

And Bufford and Baljeet entered the backyard. Bringing a baseball ball. Yah, that ball is making me confused.

And finally, Isabella entered with her full smile.

I wonder what occasion happened today.

Phineas' POV

It's Perry's 5th Anniversary living with us.

I wouldn't forget the day we got him. We just wanna have fun and play with him everyday.

I just remembered the first day that we got him as a pet.

Flashback..

Phineas' POV

Gonna have a new pet!!

Me and Ferb are so excited!

We go on a pet shop named "OWCA Pet Shop".

When we entered, there were so many pets.

There's dog, there's cat, there's many fishes.

The dog was looking at me and the cat was looking at Ferb. I don't know about Candace. No pet is looking to her.

Until Dad saw a cute, cute blue pet that looks like a beaver.

And this blue pet has his eyes looking at both of us. It is so amazing.

"Hey, Madam! We want to adopt this blue pet here."Dad said

"So you want to adopt the platypus?"she said

"Yes. Yes we do."Dad answered

We finally got the platypus and named him.

But suddenly we changed his name to Perry.

Back To Present..

Phineas' POV

Ah, those days. I wish that I could turn back time.

And we get back to playing the Platyball Baseball.

But suddenly, a invention come out of my mind.

"Ferb, I know what were gonna do today."I told Ferb

We started building the large replica of the platypus and made a Platyball Baseball Game and we are gonna ride the baseball ball.

We started working on the machine and I didn't saw (Y/N) yet. Maybe she is still asleep.

After a few minutes..

We are already done with the machine.

And suddenly (Y/N) arrive.

Your POV

I just arrived at their backyard with their platypus invention.

"So, what's in store for today?"I asked them

"We are gonna play Platyball Baseball Large Version."He replied

So excited for this.

"Wanna join us?"Phineas lend his hand on me

Oh my goodness! Looks like we are sailing together.

I take his hand and we ride the baseball ball and started to fly.

While we are flying..

"Hey where's Perry?"Phineas asked

And we crashed on a tall building. The name of the building is...

*Doofenshmirtz Evil Incorporated*

And we crashed down with happiness.

We stand up and looks like we done a really big mess there.

"Oh no. You destroyed my Inator."The Pharmacist said to us, but he didn't got mad at all

We feel sorry about that.

"I'm so sorry Mr. Pharmacist. But what's with the Inator thingy?"Phineas asked

"How can we help?"I asked

"Maybe you can just fix the machine. But it is really not for kids."He told us

"Well, we can help, Ferb and I is kinda expert on this."Phineas told him

"Aren't you a little young to do some machines like this?"The Pharmacist asked while he is looking at the destroyed machine

And suddenly, Perry appeared.

"Oh, there you are Perry."Phineas said

"Does every platypus named Perry?"Mr. Pharmacist asked

"By the way, call me Doof."he added

"Maybe in a perfect world, Mr. D."Phineas answered

And we started to work on the Inator he's talking about. It is a Inter-Dimension Inator. It opens a portal to another dimension.

And we are done. And we finally activated the machine. After Perry's blocking over the machine.

The portal opened with the unusual couch that is really fancy.

"So this is the other dimension?"I asked

"Maybe?"Doof answered

And the portal suddenly closes. But we do have an extra portal opener.

The place seems so strange as we walk over.

And we see Doof's face on the flag wherever we go.

"Wait?, Am I the ruler of this place?"Doof asked
