Mario: So, Luigi, what do you wanna do today?
(Luigi shrugs.)
Mario: What about Sonic? What does he want to do?
(Sonic chatters)
Mario: Well, a' he's a Hedgehog. They don't do much. I, a' for one, am starting to get a' bored, and boredom is something up with which I will not put! The first thing they're gonna ask us when we get back to school is "what did we do over the summer?". I mean a' no school for three months. Our life should be a rollercoaster! And I mean a' good rollercoaster. Not like that one we rode at the state fair...
(Flashback on a rollercoaster at the state fair. It goes over one tiny hill then ends.)
Fair Worker: Please exit to the left.
(End flashback.)
Mario: Man, a' that was lame. Why, if I built a rollercoaster, I would... (Gets idea; angelic chorus plays) That's it! I know what we're gonna do today!
Palutena: Mario, Luigi. I'm gonna pick up a few things. You boys stay out of trouble, okay?
Mario: Okay, Mom. (At Luigi) We're gonna build a rollercoaster!

(Palutena gets into the car; Samus comes over.)

Samus: I'm in charge, right? You did tell them I'm in charge?
Palutena: Relax, Samus, nobody has to be in charge.
Samus: But what if there's an emergency?
Palutena: Like what?
Samus: What if a... What if a satellite falls out of orbit and crashes into the house? (smiles)
Palutena: If that happens, you're in charge.
Samus: Yes!

Samus: (she enters into the backyard) Mom says I'm in charge, conditionally.
(Mario and Luigi are working on something.)
Mario: (not listening) Whatever.
Samus: Wait a minute, what are you doing?
Mario: Homework.
Samus: It's summer.
Mario: That's a' cool, you wait till the last minute then.
Samus: Well, I'm watching you. (Goes through the door) And I'm in charge—conditionally!

(Samus walks into the house and the phone rings, which she answers.)
Samus: Hello? Oh, hi, Lucina! No, I can't get to the mall right now. Mom just went to the store, she left me in charge, well, you know, conditionally.
(Mario and Luigi walk past with lots of wooden planks.)
Samus: And if you go, can you see if Captain Falcon is there? No, no, he's the cute one that works at Mr. Slushy Burger.
(Mario and Luigi walk past again, with steel beams.)
Samus: Yeah a', he totally smiled at me the last time I was there. I just about died. No, I told you I can't, I'm watching my brother and stepbrother.
(Mario and Luigi walk past with sinks and toilets.)
Samus: Yeah, and they never get into trouble, 'cause Mom never catches them. One of these days though, I'm going to see that she catches them red handed.
(Mario and Luigi walk past again, with a flamingo and a lion that roars loudly.)
Samus: Will you hold it down, I am trying to use the phone! (at Lucina) Mom left me in charge, so there will be no shenanigans today. What are they doing right now? Why do you ask? What do you mean you can see it from your house? See what?!

(Samus runs out to the backyard, she stares in shock upon seeing the rollercoaster, along with horror music.)
Samus: Mario, what is this?!
Mario: Do you like it?
Samus: (gets angry) Ooh, I'm gonna tell Mom, and when she sees what you're doing, you are going down! (runs off) Down! Down! Down! D-O-W-N, down!
(Mario and Luigi look blankly while she walks away.)
Mario: We're a' gonna need a blowtorch and some more peanut butter.

(Samus takes her bicycle and rides away only run into Peach.)
Peach: Hey Samus, is Mario... home?
Samus (ignoring Peach): Down, down, I say!

(Peach walks into the backyard.)
Peach: (hearts in eyes) Hey, Mario.
Mario: Hey a', Peach.
Peach: What'cha doin'?
Mario: Building a roller coaster.
Peach: In your backyard?
Mario: Some of it.
Peach: Wow. Isn't that kind of impossible?
Mario: Some might say.
Peach: Hey, Luigi.
(Luigi waves with the hammer.)
Peach: Does your stepbrother ever talk?
Mario: Luigi? He's more of a man of action.
(Luigi hits the nail and then his nose.)
Peach: I was gonna go to the pool, you wanna go swimming?
Mario: Kind of in the middle of a' something here.
Peach: Oh, right. Okay, I'll see you later then. (leaves)
Mario: Okay. (at Luigi) Hey, Luigi! You got enough rivets up there?
(Luigi gives a thumbs up showing they have rivets.)
Mario: Hey a', where's Sonic?

(Sonic walks around the corner of the house. He jumps up, puts on a pair of red running shoes and spindashes into a hole in the wall. He goes down tube, into a lair, where he gets an "Incoming Message".)
Snake: Ah. good morning, Agent H. The evil Dr. Eggman is up to his old tricks. For reasons unknown to us, he bought up 80% of the country's tin foil. I want you to get over to his hideout right away. Find out what he's up to and put a stop to it. As always Agent H, it is important that your cover identity as a mindless domestic pet remains intact. Now, get out there. We're all counting on you.
(Agent H jumps into a Hedgehog-themed hoverboard, and flies tough a tunnel. He leaves through a stone as he passes over Mario and Luigi.)
Mario: So a', the way I see it, the fuel rockets kick in at the mall's parking lot, then we release the Snake's during the corkscrew at the interstate. I'm gonna go get the Snake's.
(Luigi puts on his mask and starts using the blowtorch.)

(Samus runs into the store)
Samus: Mom! You gotta come home, right now.
Palutena: Did a satellite crash into the house?
Samus: No, no, no. You gotta see what Mario and Luigi are doing.
Palutena: Seems like we've had this conversation before.
Samus: What do you mean?
Palutena: I seem to recall you telling me that the boys were training monkeys to juggle bicycles, and when I come home, there was a stunning lack of monkeys.
Samus: I still don't know how they cleaned that up so fast.
Palutena: So, what's the emergency this time?
Samus: They're building a roller coaster!
Palutena: Samus, seriously, isn't Mario a little young to be a roller coaster engineer?

(Mario talks to a man in a car factory.)
Factory Manager: Aren't you a little young to be a roller coaster engineer?
Mario: Yes a'. Yes, I am.
Factory Manager: Well, I must say, I'm very impressed, the forms all seems to be in order, although I'd never seen them filled out in crayon before. So, if there's anything I can get you, anything at all, just let me know.
Mario: Do you think we could borrow one of those gadgets?
(A robot arm fixing a car is shown)

(Mario and Luigi is riding the roller coaster that builds by the robot arm.)
Mario: Now, this is the life.

(The camera zooms in on Eggman Evil Incorporated.)
(Agent H swings into the building)
Eggman: Ah, Sonic the Hedgehog, what an unexpected surprise. And by unexpected, I mean: COMPLETELY EXPECTED!
(Eggman presses a button, which activates arms that grabs Agent H.)
Eggman: I, Dr. Ivo Eggman Robotnik, have covered the entire eastern seaboard in tin foil, and when I put my giant magnet, next to my genius, Magnetism Magnifier, I will pull the East, in westerly direction, thereby reversing the rotation of the earth. You may ask yourself, why would he do this? What could he possibly have to gain? Well, let me just answer that question, I haven't really worked on all the bugs yet. I mean, tin foil alone costs a lot.

(Back at the store)
Samus: But, Mom, I'd tell you, they're building it, and it's huge!
(Luigi puts up a poster, Samus comes over to read it.)
Samus: "Mario and Luigi present the Coolest Coaster Ever now open"? Mom! (runs off)

Olimar: Mario and Luigi got a roller coaster? You think we get a discount if we bring the flier?
Another kid: Maybe we better take it.
(They take it with them just as Samus brings Palutena over.)
Samus: (Gestures toward the empty post, head turned away) There, look, look, look, see? I told you I'm not crazy, I told you!
Palutena: (dryly) And you're not crazy because...?
(Samus turns toward the post where the poster was and screams.)
Palutena: I see your point, Samus. No crazy person would scream at a post like that. I'll be at the dairy section if you wanna come yell at some cheese, or anything. (leaves)

(At the Mario house, where the start of the coaster and a stage is. Luigi lets the kids into a tent and walks onto a stage up to the microphone as if he's about to speak, then steps out of the way as Mario comes up. He grabs the microphone as disco lights shine and rock music plays.)
Mario: Ladies a' and gentlemen, boys and girls, children of all ages! May I present to you a spectacle most of the morning in the making: The Coolest...Coaster...EVER!
(Luigi reveals the coaster. A bird files into it.)
Mario: So, who wants to go first?
(Everyone raises their hands.)

(On the rollercoaster...)
Mario: To fasten, insert the tab into the metal buckle. To release, just pull back on the a'—oops.
(Mario drops the safety belt.)
Mario: Well, you get the picture. Well a', that's about it. Enjoy the ride.
(The car goes over the top, and stops, viewing the long drop.)
Mario: You all a' signed the waivers, right?
(Down it goes; the car goes around the coaster, on the track. Everyone screams.)
(Going through the drop of Snake's)
Mario: Relax a', they're just rubber!
(The car goes into a bucket of mud, then exits. Later, it goes through a car wash, to be cleaned from the mud.)
Mario: Hey, look a', there comes the AH-AH-AH-AH!
(The track is going up and down repeatedly, creating four "AH"s.)

(The car zooms around the Eggman Evil Incorporated building.)
Eggman: ...I really make of my money back, I-I-I want a really spacey real estate, and sell it again.
(Agent H kicks his leg that sends a screw at Eggman, which he ducks for.)
Eggman: Ha! You missed!
(The screw flies to the roof and hitting a line, which throws it back at Eggman's foot.)
Eggman: Aaaoow! Ow, Ow, Ow, Aaooww!
(Eggman jumps around and accidentally releases Agent H, who quickly spindashes into him where he lands on Eggman's foot.) Aaaoow! (During the fight, Eggman activates the Magnetism Magnifier.)
Eggman: Now you are too late! Quake in your boots and watch helplessly, as the unimaginable electromagnetic forces, pull the eastern seaboard, thereby reversing the rotation of the Ea-
(All the tin foil releases from the buildings)
Eggman: Well... that didn't work.
(The tin foil forms into a giant ball, flying through the air)
Eggman: And now, we have a two-ton ball of tin foil traveling 200 miles per hour directly at us! Quickly, we must separate the magnet from the Magnifier before it's too late!

(At the store)
Palutena: Now I know I have that club card in here somewhere. I always have it with me, but my purse is a disaster area, you know how it is.
(Samus goes outside and sees the coaster)
Samus: Oh, oh, oh, oh, oh! Mom? Mom!? (She rushes off.)

(Eggman Evil Incorporated building)
Eggman: It's no use! It's no use! We are doomed!
(Sonic sees a helicopter. He run onto the magnet and fires a grappling hook at it. He quickly wraps some of the rope around the magnet. The helicopter flies off, taking the magnet with it.)
Eggman: You did it! You saved us, Sonic the Hedgehog! (The ball of tin foil crashes through the building brining Eggman with it.) Curse you, Sonic the Hedgehog!
(The magnet pulls a piece of the Magnetism Magnifier onto it, and gets stuck on the coaster, which then follows the helicopter into the sky.)

(Samus pulls Palutena into the parking lot, not noticing the coaster has been removed.)
Samus: Look, look, look, see?
Palutena: (pause) Okay, I give up, what am I supposed to be looking at?
Samus: (turns to see the empty parking lot) No! It's not POSSIBLE!
Palutena: (going back inside) I'm gonna go get the cart.
Samus: IT WAS RIGHT HERE AND IT WAS HUGE! (sees the rollercoaster fly away) MOM!
Palutena: (walks past, taking her cart) Time to go. I've got frozens.
Samus: Okay, so you think that Mario and Luigi are still under that stupid tree in the backyard, right?
Palutena: Well, yes, that would be my guess.
Samus: Fine, then let's go home, now! (She pushes the cart.)

(Sonic sees that the helicopter is smoking and cuts the rope, which drops the rollercoaster down. He drops down onto the coaster and in the cart, right behind Mario and Luigi.)
Mario: Oh, a' there you are, Sonic.
(Sonic chatters)
Mario: Nice a' shoe necklace, Peach.
(Peach takes off Agent H's running shoes that were around her neck and looks at it, confused.)
(The car goes to the end of the track and flies onto a construction area and flings into the air.)
Mario: Funny, I don't a' remember this in the blueprints.
(An airplane picks up the car by the tail)
Mario: And I'm a' sure this is new.

(Samus sees the airplane from Palutena's car.)
Samus: Hehehehehehehehehehe!
Palutena: I worry about you sometimes, Samus.

(The coaster car drops down and onto the Statue of Liberty, bending and throwing it to the woods. It lands on a pine tree which bends so they end up in front of Mr Slushy Burger.)
Captain Falcon: Welcome to Mr. Slushy Burger, may I take your order?
Mario: Anyone a' want fries?

(Before taking any orders, the tree bends back and throws them to France, Paris)
French Man: Croissant?
Mario: Anyone want a'... (French accent) "quasson"?

(The car gets flung into orbit)
Singing Voice: Aahh-Aahh-Aaahhh
(A satellite flies by)
Mario: You know a', if that thing crashes into earth, Samus is in charge.
(The car suddenly falls down towards earth, towards the Tri-State area. The front of the car begins to burn like a meteor.)
Mario: We should have a' charged more.

(Palutena pulls the car on the driveway and Samus jumps out.)
Palutena: Okay, we're here, are you happy now, Samus?
(Horror music plays; Samus opens the gate to the backyard and doesn't see Mario or Luigi.)
Samus: Yes! (At Palutena) See, Mom? I told you they weren't there!
(Samus opens the gate and gestures toward the tree with her eyes closed, as we hear a sound of leaves rustling. Palutena pokes her head through the gate opening and smiles.)
Palutena: Oh, hi, boys.
(Samus opens her eyes and her mood changes to shock; cut to under the tree to show Mario and Luigi are suddenly here.)
Mario: Hi, Mom.
Palutena: Come on Samus, help me with the groceries. (goes off)
Samus: But, but, but, but, but, but, but... (Continues under)
Palutena: (comes back) Let's go. (pulls her away)

(Kids drop down from the tree.)
Kid: Hey Mario, that was great.
Olimar: Way too cool.
Third kid: That was awesome! Can we do it again?
Mario: Sorry, a' only one ride per customer.
(Peach comes down from the tree.)
Peach: That was great, Mario. So, what are you gonna do tomorrow?
Mario: Don't know yet.
Peach: (pets Sonic) Maybe you could teach Sonic some tricks.
Mario: Well, he is a Hedgehog, they don't do much.
Peach: Cool. See you tomorrow. (goes to the gate) It really was the coolest coaster ever. You guys make a great team.
Mario: Well, a brother is a brother, but I couldn't have asked for a better one than Luigi. You know what I mean?
(Luigi burps rudely)
Mario: Oh-ho-ho, man! I could a' smell the peanut butter!
Peach: Well, that was impressive. See you, guys. (leaves)

Mario: So, what should we do a' tomorrow? There's a world of possibilities. (pause) Maybe we should make a list!
(The coaster car explodes in the tree, a car alarm and a dog barking can be heard.)
Samus: (from inside) Mom!
Palutena: (from inside) Give it a rest, Samus!
(The tin foil ball rolls in the background while Eggman was still crushed.)
