After around 4 months of planning, writing and rewriting, here is the long overdue sequel to Double Trouble! I am sincerely sorry for the wait, but I've been really busy. But here it is now, so no complaints from this guy. Prepare yourself, as an exciting adventure unfolds!

Chapter 1: Let's Visit Mobius!

Danville: Phineas and Ferb's backyard

Phineas and Ferb were under their favorite tree relaxing.

"Hey Ferb," The red headed boy turned to his step-brother. "Remember our adventure with Sonic last summer?"

Ferb, the green-haired boy next to Phineas, nodded.

"That was some adventure." Phineas said, recalling the fight against Metal Sonic and Eggman Nega. "It's been awhile since we've seen them. Maybe…"

His thoughts were interrupted by the sound of the gate door being opened, and a familiar voice. "Hey Phineas!" A 13 year old girl greeted. "Whatcha Doin?"

Phineas turned to the girl in pink at the entrance of the yard. "Oh, hey Isabella!" He greeted his friend. "Ferb and I were just thinking about our adventure with Sonic last year. Remember that?"

"Oh yeah." Isabella quickly nodded. "I still can't believe that nobody believes that. They all still think it was just a hoax or something."

"Yeah," Phineas nodded. After a minute of awkward silence he suddenly jumped up. "That's it!" He exclaimed, startling Ferb and Isabella. "I know what we're going to do today! We're going to make a machine that will allow us to visit Sonic's world!"

Ferb and Isabella thought it was an excellent idea, and the three quickly started work on the machine.

Phineas and Ferb's house: Living Room

Candace and her mom were talking.

"Now remember Candace," Her mom reminded. "No boys over while I am gone. Your dad is in Seattle at an antique convention, and I'll be gone for a week. I don't want any boys over. Is that understood?"

The fifteen year old nodded. "I got it." She said. "The only boy I'd have over anyway would be Jeremy. And with his promotion at his job he's too busy to come over."

"And remember, you're in charge." Her mom said, walking out the door. "Love you!"

"Love you too mom!" Candace said, waving. She then heard the sound of Phineas and Ferb working, and quickly ran out the door. "Wait mom! Ungh!" She exclaimed, watching her mom drive away. "Phineas and Ferb! I'm so getting you!" She stomped to the backyard, where she suddenly stopped in surprise, for in front of her was a strange looking machine with a large platform on top. Working on the machine were Phineas, Ferb, Isabella, Buford, Baljeet, and Irving. "Phineas and Ferb!" Candace demanded. "What is this thing!?"

"Oh hi Candace!" Phineas greeted, slamming in a nail. "We're just putting the finishing touches on our Galactic Transporter."

"Yeah yeah yeah, but what does it do?" Candace said, looking skeptically at it.

Just then a blond haired teen looked at her from behind the machine. "Phineas said it will transport us to a different world!" He said.

"Je…Jeremy!?" Candace almost shouted in her surprise. "What are you doing here!?"

"Helping out." He said, smiling. "Why don't you join us? It's almost done—"

"There!" Phineas said, finishing up. "That should do it."

The team stepped back and looked at the machine.

"Oh Phineas!" Isabella exclaimed. "It looks wonderful!"

"Indeed!" Baljeet agreed. "We all did a great job in making this!"

"And I'm just glad that I got several pictures of us working!" Irving said, looking at his camera.

"Well, next stop Mobius!" Phineas said, starting to walk to the platform

"Hold up!" Candace said, making Phineas turn around in confusion. "You're not going anywhere! Mom left me in charge, and you're not going to get away with building these crazy contraptions!"

"Come on Candace." Isabella said. "Why don't you come with us? It's been a year since we've seen Sonic and his friends."

"Oh, is that what this is all about!?" Candace snapped. "Well in that case we are certainly NOT going! The last thing I need is for you guys to be put into mortal danger by that hedgehog!"

"Uh…that was actually by the metal robot." Phineas reminded her. "The hedgehog helped us out. Remember?"

"Whatever!"

"Come on Candace." Jeremy said, taking her hand. "It'll be fun."

"And if it makes you feel better, we built a remote that controls the machine even through different worlds." Phineas encouraged. "If anything goes wrong we'll be back home in a flash."

"Well…" Candace said, hesitating. "Fine! But if ANYTHING goes wrong you take us right back home!"

"Sure thing Candace." Phineas said, walking toward the platform. "Well, all aboard!"

The others walked onto the platform, where Perry was already laying down.

"Let's do this Ferb!" Phineas signaled to his step-brother, who pushed a button on a remote. A bright light engulfed the gang, and when it cleared there was no sign of them.

To be continued…

Phineas and Ferb are on their way to visit Sonic after one year! But does Sonic still remember them? Has Sonic changed at all? Find out next time in Double Trouble: The Sequel!

A/N: Chapter 1 done! Sooo...here it is ladies and gentlemen! Sorry for the long wait, I was working on a few other things, and then my grandma died, so it was REALLY hectic! But it's settling back down now. So, for the machine and remote: The way the remote works is the same as it does in the Second Dimension movie. If you haven't watched it, you should! And Jeremy is in this! I don't think I added him in the last one, which I felt bad about, but here he is now! If you're enjoying this, or have any questions, please comment (review) and I'll answer you. Thanks for reading!
