Sonic the Hedgehog and Phineas and Ferb: Double Trouble!

Chapter 1: The Beginning

Danville: Phineas' and Ferbs' Backyard

"So Ferb, what do you want to do today?" The young boy with red hair asked his step-brother, who just shrugged.

"Hmm, you know Ferb, ever since our adventure with the super heroes; it's been pretty calm around here." He noted. "I mean, we still build some awesome things, but we need to make someone really awesome!"

The back door opens and a fifteen year old girl walks out.

"Phineas, Ferb!" She called. "What are you guys doing?"

"Just thinking on what we should do today." Phineas replied.

"Yeah, well you better not come up with anything crazy. Better yet, don't come up with anything at all!" After saying that, she went back inside and closed the door.

Phineas sat watching his sister walk away. I wonder why Candace doesn't like us building stuff. He wondered. She has fun on a lot of them. Shaking his head, he continued to think on what to build, when the gate door opened, and a familiar young girl walked in.

"Hi Phineas!" She said cheerily.

"Oh, hi Isabella!" Phineas said, looking toward his friend.

"Whatcha Doin?" She wondered.

"Just trying to figure out what we should do today." Phineas told her. "Hey! Do you have any patches that you need to accomplish?"

The girl began thinking. "Lets' see… well, here's one!" She said. "You'll like this one Phineas. It's a hover patch."

Phineas was a little confused, as what she said didn't exactly tell what it was. "What do you need to do to get that?" He asked.

"To get it, I have to ride a…hover board?" Now she was confused. "But…we don't have any hover boards."

Phineas jumped up when Isabella said that. "I got it!" He said excitingly. "I know what we're going to do today! We're going to build the coolest hover boards ever!"

Isabella was taken back when Phineas said that. "You mean you'll really do that?" She asked.

Phineas nodded. "Of course." He said. "It sounds like a lot of fun, huh Ferb?"

Ferb nodded his agreement.

"Thank you Phineas!" Isabella's voice rang with happiness. "I knew that you would do it!"

"No problem. Hey," Phineas looked around the yard. "Where's Perry?"

Danville: Agent P Secret HQ

Perry the Platypus went out of the elevator and headed for the main screen, where a message was waiting for him.

"Ahh, good morning Agent P!" The man speaking the message said. "I hope you had a pleasant vacation. Now, back to business. Dr. Doofenshmirtz has been seen working with some strange energy signals, and we don't know what it could mean. Make sure he's not planning anything evil. Monogram out!"

Agent P quickly got up and headed for the Dr.'s building.

Danville: Doofenshmirtz Evil Incorporated.

Agent P broke through the wall and landed in front of a man in a lab coat.

"Ahh, Perry the Platypus." The man said. "What an unexpected surprise. And by unexpected I mean completely expected!"

He pushed a button, which activated a trap that caught Agent P.

"So, I bet you're here because of the experiments I've been doing huh?"

"Krrr" Perry replied.

"Well, let me introduce you to my latest inator. He stands up and points to a machine. "This, Perry the Platypus, is my Melt-Inator! With this baby, I will melt every plastic, rubber, and glass thing in the entire Tri-State area! And then," Pointing to another machine. "I will activate my Energy-Inator, which will convert all the energy to fuel, which would be evaporated by my Evaporator-Inator." Points to a third machine. "Now I know that it seems complicated but trust me, I thought this one through. But… should I do the Melt-Inator first or the Energy-Inator? Eh, whatever. I'll do the Energy-Inator first."

He walks to the machine and aims it at the city.

"Now, Perry the Platypus. Prepare to see all the cities energy converted to fuel!" He pushes a button which not only warms up the machine, but disables Perry's trap. "Huh?" He wondered, only to get kicked by Perry.

"Perry the Platypus, how did you escape?" He asked.

Perry threw his fedora at Doof, which knocked him down. While that was happening, Perry destroyed the Inator with one kick.

"Ahh, man. One kick and you destroy my Inator!" Doofenshmirtz said. "That wasn't supposed to happen! Curse you Perry the Platypus!"

Perry activated his jet pack and flew away from the building.

"Ahh, come on. Now I have to build this all over again." He kicks the machine, which shoots an energy beam into the sky. "Whoops! Didn't see that coming!" He exclaimed.

Danville: Phineas' and Ferbs' Backyard

Phineas and Ferb had just finished working.

"Done!" Phineas said proudly.

"They look excellent Phineas!" Exclaimed Isabella.

"Yes, yes they do." Ferb remarked.

The gate door opens and two more kids walk in.

"Hi Phineas! Hi Ferb!" A young Indian boy says.

"Hi Baljeet!" Phineas said, happy to see him.

"Whatcha Doin?" The Dutch boy next to him asked.

"Buford!" Isabella said. "That's my line!"

"Oh yeah." Buford said. Why does she get a secret line?

"We just finished building hover boards. You guys want to ride them with us?" Phineas asked.

"Sure!" Baljeet said. "It sounds pretty fun."

"All right then. Lets' do this!"

Phineas and his friends got on the hover boards and turned them on.

"Whoa!" Buford exclaimed. "This is beyond cool!"

"I know." Phineas said. "Isabella gave us the idea for this one."

Isabella blushed a little when Phineas said that.

"Now, if you want to go faster, you just crouch lower on the board." Phineas started to explain. "You steer it like a skateboard."

"All right then. Lets' go then!" Buford was excited to do this.

"Lets' go gang!"

Phineas and his friends zoomed out of the yard and headed downtown.
