Chapter Ten: Law Of Luck

It was a great day at Danvile when Phineas, Ferb, Isabella, Bufford, Baljeet and Y/N are working on a new invention today.

They are looking for blueprints and looking for something that can help them to make something big today.

And suddenly, a mysterious group of people appeared at the backyard o Phineas and Ferb.

"Uhm. Mr. Evil. We need to stop you. We need to save something. Ciao!" A man with a white mustache and a guy that wears a green suit

And a man that is tall who wears a track suit.

The two disappears and the guy was left alone at the backyard.

Phineas saw the guy alone and try to approach him.

"Hi. What's your name?" Phineas asked him

"Hi. I'm Milo. Milo Murphy." Milo lend his hand and they both shake hands

Milo wears a beige shirt and pink sweater vest with some brown-greyish stripes on it.

And suddenly an empty box falls into Baljeet.

"Seriously?" Baljeet said

As Phineas walks with Milo inside the backyard, the blueprints starts to fly away from the backyard. Y/N tries to chase the blueprints but it just flew away.

And suddenly, two people stop by at the backyard of Phineas and Ferb and looks like they are looking for someone.

"Milo, there you are!" A girl that wears a white quarter length sleeve jacket and a black shirt underneath it.

They both enter the backyard.

"We've been looking on Danville everywhere for you." A guy said that is tall and wears a yellow t-shirt

"Sorry, guys. The guy with white mustache and Mr. Tracksuit left me here." Milo said

Y/N suddenly remembers something about Milo.

"Milo Murphy? Right?" Y/N asked

"Yes. Yes I am." Milo answered

Y/N hugs Milo tight. And Milo is clueless why Y/N is hugging him.

"I'm Y/N. Your childhood friend." Y/N said to Milo

Milo thinks about the name "Y/N".

"Wow. It's you, Y/N!" Milo hugs Y/N

And Y/N explains everything that happened when Milo and her first met.

"So that explains everything." Phineas said

"By the way, this is my friends. Zack and Melissa." Milo said

And suddenly, a bird just landed on Zack's head and the bird begin pecking Zack's hair.

"Ouch!"

"Murphy's Law, isn't it?" Melissa said

"Well. It is pretty strong. And you can't avoid it so yeah. You still need to be happy because the more sad you are, more mishaps will happen." Milo told to everyone in the backyard

"Murphy's Law? What is it?" Isabella asked

They all sit down in the grass and Milo explains everything about Murphy's Law.

"So that's what Murphy's Law." Phineas said

"So. We didn't know that it is actually Quad-State Area. I only know Tri-State Area." Baljeet said

"Y/N? How well you know Milo?" Isabella asked

Y/N explains everything happened to him and Milo during their childhood.  Y/N experienced many mishaps with Milo during her childhood. Because of Milo's Hereditary Muprhy's Law.

Candace walks into the backyard.

"Hey! Who are these guys? And why does this girl have the same hair color as me?" Candace asked and points out Melissa

Melissa stands up and approach Candace.

They both look at each other. And see their similarities.

"Hey!" They both said

And suddenly, a ball drops into Candace's head.

"Ouch!" Candace said

Meanwhile, at the building of Doofenshmirtz.  The guy with white mustache and the guy that wears a tracksuit teleports to the building of Doofensmirtz.

"Cavendish, what are we doing here?" The guy named Dakota asked

They are hiding near the door.

"This guy has a device that will destroy every pistachios in the world. So we need to stop him." Cavendish said

Cavendish and Dakota teleports through the Pistachio-Gone-Inator.

They try to dismantle the device but Dakota accidentally pressed the self-destruct button.

"Really Dakota?" Cavendish said

"What?, I didn't know he puts self-destruct button in his inventions." Dakota said

"Must've been the fault of that kid." Cavendish said

Meanwhile, Candace with Melissa, Milo and Zack goes to the building of Doofenshmirtz to visit Candace's friend Vanessa.

As Candace opens the door, the device exploded.

After the explosion, the smoke clears and Vanessa goes out of her room. While Candace face is full of ashes from that explosion.

"That's my dad's room, Candace." Vanessa said

"Oh. Yeah. I totally forgot." Candace wipes the ashes in her face

"I thought I could borrow some CD's from you." Candace said

Vanessa brings out the CD's in her room and gave it to Candace.

"Well. Thanks for the complete series of Strangers Strangers. It's a horror movie right?" Candace asked

"I don't know. But it's a great movie." Vanessa said

Candace, Milo, Melissa and Zack goes back to the backyard. And all of the people there suddenly disappear.

"Where are they?" Candace asked

They all look at all the sides of the house and they have been found nowhere.

"Where did they go?"
