Chapter 1: Road Trip

Author's Notes: Here's another crossover for y'all, This time with Super Mario and Phineas and Ferb. (Based off of Super Phinio Bros by Christopher Mantynen). Please Follow, Fav, and Review, too.

Disclaimer: I own nothing of Super Mario and Phineas and Ferb.

There are One-hundred-and-Five days of Summer Vacation,

And School comes along to end it,

So the annual problem for our generation is finding a good way to spend it.

Life May Be...

Building a rocket sled on top of launch sled, sliding down a speedjump tower.

Building a sandwich the size of Goliath or giving a Goomba a shower.

Building a roller coaster, Creating Nanobots, or Locating Koopastien's brain (It's over Here)

Finding a Dodo Bird, Painting a continent, or driving your sister insane (PHINEAS!)

As you can see, there's a whole lotta stuff to do before School starts this fall (c'mon, Perry!)

So stick with us 'cuz Phineas and Ferb are gonna do it a-all!

So stick with us 'cuz Phineas and Ferb are gonna do it all.

Mom! Phineas and Ferb are making a Super Mario crossover!

It was a good day for a road trip. This is exactly what the Koopas are doing today in their 10-wheeled SUV-based minivan (With a bowser motif, of course).

"Why do I always have to sit in the middle when dad keeps the sunroof closed?" griped Larry, the second-youngest koopa with a light-blue mohawk.

"It'll be ok, Larry. He'll open it after dusk." Wendy, the only female on this trip, said with a bright smile on her lips.

"According to my watch, Sunrise was just an hour ago at 6:31 AM." Iggy, the smartest koopa of the group with pineapple-ish hair, informed the other koopas, to Larry's dismay.

"Oh, come on! 14 more hours 'til Sunset?" complained Larry.

"There's not much of a point in opening the sunroof if there's nothing to see up there. At night, there are stars which are part of constellations ." Ludwig, the eldest child with awesome superpowers and former heir to the throne, responded. "Besides, the Sun can hurt your eyes and eventually blind you if you keep looking at it, even through solar filters. Bad idea, Larry."

"Can you shut up? I'm trying to play WarioWare Gold and I keep failing this mike microgame because you keep yapping nonstop," complained Lemmy, the smallest, fun-loving koopa in terms of size.

"Lemmy! What are you doing? You're supposed to look at the beautiful sights around us, Ok?" Morton, the strongest (but most dim-witted) koopa, notified Lemmy about the beautiful scenery around them.

"Shhh! I'm trying to complete this microgame, but everyone is talking so loud that they trigger the mike on my device which makes me fail the microgame."

"Part of that may be the minivan itself." Ludwig reminded Lemmy about the noise.

"I can't wait to reach Danville. I heard that there are 2 boys named 'Phineas' and 'Ferb' that made lots of stuff, from a huge rollercoaster the size of the entire city to a rocket that can reach interstellar space without discarding anything. Too bad the entire thing is discarded when their mom comes home even though their sister Candice tries to bust them." Roy, the koopa with a pink head and a bill blaster that can be carried in one hand, commented with something off-topic.

At the same time, they went into a tunnel, and on the other side, they saw the high-rise skyscrapers of Downtown Danville in the distance. The most obvious building was Doofinshmirtz Evil Incorporated.

"Do you really think we're gonna meet them?" Bowser Jr, current heir to the throne, retorted.

"Ok, kids. we're at the Danville city limits. Get prepared to get out of the vehicle soon." Bowser, king of the koopa kingdom and father of 8 children, announced to the koopas.

"Are we gonna meet Phineas and Ferb? I heard they're popular with the local children." asked Larry.

"If we have time, we might. There are other things to see in Danville first." Bowser responded.

"Anyone else want to see them?" Larry asked. All of them but Ludwig raised their hands to show proof. "Good. I think I contacted the show's director, too."

"Ok, if you have permission from their director, then Yes."

Several minutes later...

"We should be expecting our guests any minute now. Funny how a warp pipe hasn't appeared yet." Phineas, a very optomistic and creative boy, said while a strange-looking automobile was backing into their driveway.

"Whatcha doin'?" Isabella, super cute all the way to the core, said at the same time that strange automobile started parking. "One question. What is that scary-looking car that just drove in here?"

"I dunno, I think it looks cool." Buford, the local bully, commented on that scary-looking automobile in the driveway.

"Buford! You never know, it could be a nasty surprise." Balajeet, super smart and school-loving, commented while the door opened and a koopa was revealed. "Or not."

"Looks like we made it" Larry said while getting out of their automobile.

"Oh, looks like they arrived on time. I was wondering why there was no warp pipe. Guess we'll start greeting each other soon." Phineas said while Ferb, the engineer of the group, stood next to him.

"Hello, there. my name is Larry, the youngest of the Koopalings. Nice to meet ya'"

"MORTON LIKE PHINEAS AND FERB."

"What'cha doin'?"

"Hey, that's my line!" Isabella yelled at Wendy.

"Oh, sorry. Didn't know it bothers you when someone else says your line." Wendy

"Nice to meet y'all. Wondering what you have in mind today," asked Iggy

"Hey, Phineas. Wonder what we're gonna do today. Better be something good." Lemmy chimed in.

"What's up, guys?" greeted Roy.

"Honesty not sure," reposted Phineas.

"Ok, kids. I'll be back in 7 hours, Ok? Be safe, too."

"Anyways, where's Perry?"

To be Continued...
