Phineas and Ferb's Dinosaur Adventure – Chapter 1: A Grand Idea

A/N: Hello everyone! If you like dinosaurs and the Phineas and Ferb show, then you probably will enjoy this story. It isn't going to be as long as my other fanfiction that I recently finished, but it should still be pretty cool. In this story, expect most of the main characters from the show and a load of cool dinosaurs! I hope you guys all like this first chapter. Please enjoy!

PS. Before we get started, I must say: please be nice when posting reviews; that is, no profanities or other uses of foul language and just don't be mean. Though I'll take constructive criticism if it is presented to me nicely.

Disclaimer: I don't own anything related to Phineas and Ferb.

"And this leads us to the most terrifying dinosaur of all," the narrator on television said, "Tyrannosaurus rex."

Phineas Flynn and Ferb Fletcher were in the living room sitting on the couch watching a documentary on dinosaurs. It was a beautiful day outside – the sky was blue and cloudless and the temperature was nice – but after yesterday's event, the two step-brothers were taking it easy today.

The Tyrannosaurus on screen opened its jaws and emitted a loud bellow. Phineas snapped his fingers. "Hey, I remember that guy!" Phineas said. "Seems like just yesterday we fixed that time machine in the museum. Glad we didn't get eaten by that T. rex. Hey, Ferb?"

Ferb nodded his head. As usual, Ferb wasn't saying much. He normally liked to stick to his seldom-speaking-words-of-wisdom; in other words, he didn't speak often, but when he did, it was often profound. Today was no different.

As the T. rex rampaged around on screen, Phineas noticed their pet platypus, Perry, walk over to them before hopping on the couch to sit down.

"Oh hey, Perry," Phineas said, patting Perry on the head.

Perry chattered.

The narrator on television continued, "Tyrannosaurus rex was one of the largest carnivores ever to walk the earth, and the largest ever in North America. It grew some 13 meters from nose to tail, stood 20 feet tall and weighed five to seven tons in weight. It was a monstrous animal." The T. rex on screen walked to the edge of a forest where it saw a herd of duck-billed dinosaurs – or hadrosaurs – grazing. Seeing this, the dinosaur slowly stalked its next meal. "Based on studies of T. rex's thermoregulation, it appears that they had to eat–"

"You know, Ferb," Phineas began, "I just noticed something. T. rex sure gets a lot of attention, and it is a cool dinosaur and all, but there are so many other cool ones out there too that few people ever get a chance to learn about. I mean, look at this."

Phineas changed the channel and a T. rex appeared, roaring at the top of its lungs; next channel – a T. rex was rushing out of a jungle before snagging a helpless ornithomimid, or ostrich-like dinosaur, in its jaws and shaking it around like a rag doll; next channel – a scene of T. rex on its back, lunging King Kong into the air with his legs; next channel – a black-and-white movie showed a T. rex attacking a large Triceratops; next channel – a T. rex was rampaging off a cargo ship and charging into San Diego; next channel – the screen portrayed a Tyrannosaurus dancing around in the streets of New York City during the Thanksgiving Day Parade . . . the list went on and on!

"Wouldn't it be cool if some of these television shows and movies showed off some dinosaurs other than T. rex . . ." Phineas paused, "or better yet, it might be better if we saw the dinosaurs in the flesh . . ." Inside his head, Phineas was contemplating his next plan . . . his next grand idea. "Hey, Ferb! I know what we're gonna to do today!" Ferb looked away from the TV and toward his stepbrother. "We can travel back in time again and explore the world of dinosaurs! Kind of like the first time we went back in time, but this time we'll go to a different Mesozoic habitat. AND we can document the animals and plant species we find, perhaps in some sort of photo journal. That's one thing we didn't do last time – we went back in time and didn't even take pictures or video footage. This time we can do that! What do you say, Ferb?"

Ferb gave his brother a thumbs up.

"Great, then let's get a move on! Let's go over to the Danville Museum of Natural History and check out the time machine. Hopefully it's still working since we last used it. That sound cool, Perry?"

"Grrr," Perry chattered.

With that, the two boys left the couch and headed out of the living room, followed by Perry. They passed Lawrence, their father on the way out.

"Hello, boys," Lawrence said. "Are you guys using the TV?"

"Not anymore," Phineas said. "We're going outside. Catch you later, Dad."

Lawrence shrugged. "Alright then." He sat on the couch and began flipping through channels until he found a channel with the same program Phineas and Ferb were watching about T. rex. "A goody, the dinosaur special I was watching last week is back on!" he said.

Phineas whistled a tune to himself as he rummaged through some boxes in the garage. Ferb was piling tools in his toolbox neatly. Once packed up, he grabbed his backpack and slung it over his bag. Phineas looked at his stepbrother and did the same with his bag. He put a safari hat on top of his head. "Here's your hat, Ferb," he said. Ferb took the hat from Phineas and placed it on his head. "This time we're a little more prepared."

Their Mom, Linda, came into the garage. "Oh don't you two look cute," she said.

"Hi, Mom!" Phineas said. Then he noticed his mother had freshly baked bread on a plate in her hands. "What are you doing today?"

"I'll be going to over to Vivian's later for cards," Linda said, "right after the pie I was baking is finished rising. What are you two up to today?"

"We're going to go back in time and check out some dinosaurs!" Phineas exclaimed.

"Such active imaginations," Linda said to herself. "Alright then, just make sure you don't bring mud into the house. I just cleaned the floor."

"No problem, Mom." Linda went back inside and Phineas said, "Wait a minute, we need the blueprints for the time machine."

He quickly went into a drawer filled with old blueprints for different inventions. "Let's see . . . the roller coaster, we should do that again Ferb . . . the rainbow-inator . . ."

"Hi, Phineas!" Isabella Garcia-Shapiro said as she rounded the corner. "Whatcha doin'?"

"Oh hi, Isabella," Phineas answered. "We're going to the Danville Museum to go back in time to see some dinosaurs again."

"Didn't we already do that?"

"Sure, but this time it's different. We're going to be like real scientists: we're going to make a bunch of scientific observations, take pictures to fill up our photo journal and . . . well, we're going to be looking at some dinosaurs other than T. rex. I mean, we don't want to–"

Isabella giggled. "– get the time machine broken again?"

Phineas grinned. "That wasn't what I was going to say, but sure. Hate to have that happen again. So you comin'?"

"You bet I am! I'll go get the other Fireside Girls and we'll see you at the museum."

"Alright, Phineas. Should I notify Baljeet, Baljeet and Buford?"

"Sure."

Phineas, Ferb (who was holding Perry), Buford, Baljeet, Irving, Isabella and the Fireside Girls: Adyson, Ginger, Gretchen, Holly, Katie and Milly walked up the steps leading into the Danville Museum of Natural History.

"Well gang, here we are," Phineas said.

Buford asked, "Why do all these big museums have the same name? The 'Museum of Natural History'."

"It is a status symbol, Buford. It lets people know the significance of the museum they are about to enter."

"Whatever."

Phineas glanced at all the different wings of the museum and almost went into the fossil department until he remembered that the time machine was actually in the section called Gadgets Through the Ages. "This way guys."

"So where are we going, again?" Buford asked.

"Buford," Isabella hissed. "Do you remember anything I told you earlier?"

"Sure, something about going back in time or something."

Isabella sighed. "You need to listen a little better, Buford. We're going to study some dinosaurs."

"Then shouldn't we be going to the fossil exhibit–?"

"Real dinosaurs, Burford. Keep up."

"OK, that sounds more exciting."

"Fossils are exciting too you know, Buford," Baljeet said.

Just then, a guard approached the group. "Hello, kids," he said, "where you off to?"

"We're just heading over to Gadgets Through the Ages," Phineas answered. "We're going to use the time machine."

"Sorry, but that section of the museum is closed today. We're remodeling."

"Remodeling?" Irving said. "Why would you need to remodel? They're gadgets through the ages, they're not supposed to be updated."

"He is right," Baljeet agreed. "They are supposed to represent mankind's progression in how we've used certain–"

"Oh no," the guard said, "not that kind of remodeling. Just basic paint and stuff. It's going to be more . . . gadgety-themed."

"OK," Phineas said. "But you won't be removing any of the exhibits, right?"

"Nah. The Gadgets Through the Ages just isn't suitable for guests yet."

Just then, a loud crash was heard from the Gadgets Through the Ages part of the museum. "I'm OK!" someone cried.

"Anyway," the guard said, "is there anything I can help you guys with?"

"No, that's it," Phineas said. "Thanks anyway."

Not having any reason to stay in the museum, Phineas and the gang went back outside.

Phineas sighed. "Well that's a bummer."

"You know, we could just build a time machine," Milly offered.

"Hey! I know what else we're gonna to do today! We can still go back in time! Do we have any blueprints to make a time machine with the pieces we have at home?" Ferb shook his head. "Drat."

Isabella said, "Don't worry, Phineas. We have a section on how to construct a time portal in our Fireside Girl handbooks."

"Do you guys have everything in your handbooks?" Buford asked sarcastically.

"Alright everyone, let's head back to my house!" Phineas said.

A/N: How do you guys like this first chapter? I hope it lived up to all of your expectations. I can't wait to publish more chapters to this story! When I was trying to conceive an idea for a Phineas and Ferb fanfiction, I couldn't help but notice how many times Phineas and Ferb and the gang have time-traveled: twice in the entire show so far! They've gone to outer space quite a few times, but out of all the hundreds of episodes, they've only gone back in time twice, and only one of those times was backwards in time. I also noticed a lack of dinosaur-related Phineas and Ferb fanfictions on this website (if it wasn't already obvious, I'm a dinosaur-nut! Lol!). These two factors led me to write this story. Anyway, until chapter two is up, please make sure to follow, favorite and review on this story! R&r!
