Here's how the opening of the film and Brian's idea goes in Wrath of the Indominus Rex.
Patchy: Yee-ha! Hey kids! Now, you're probably wondering, "Hmm, what's Patchy doing in a cave?" good question, you little… [grumbles to self. The dinosaur walks over to a wall where there a cave drawings of Sponge and jellyfish] Well, it's because today's Weekenders and friends' Amazing Explorations movie takes place in Jurassic World [cut to the drawing of person with a stick and ponyfish] …back when man struggled for survival [pan over to show a dinosaur eating Tino and Brian running away] and dinosaurs ruled the Earth. [the dinosaur walks back into the middle of the room] Isn't that right, Bronty? But I'm riding YOU now! [pan out to reveal Patchy is wearing the dinosaur like an inner tube, and he struggles to get out of it, but falls over on his side. He screams for aide and two stagehands run over to him. Cut to a "Please Stand By" screen. Soon, Patchy is up] Like I was saying, prehistoric times were the greatest. [cut to black-and-white footage of cavemen] It was a simpler time [cut to a picture of a caveman with a finger up his nose] with simpler pleasures! [cut to Patchy, holding up two robes, identical to each other and the one Patchy is wearing] Your clothes always match! [cut to Patchy with a paintbrush] You can draw on the walls! And nobody yell at ya! [he picks up a giant club] It was much easier to hit a baseball! [he sits down on the couch] Oh yeah, prehistoric times were the best. [he gasps] Hey kids! Are those pterodactyl wings I hear 'a flappin'? I think I know who that is! Please welcome the Potty-dactyl!
[Potty flies in, but has a head visor and jetpack on]
Potty: [squawk] Sorry I'm late.
Patchy: Potty! Why aren't you wearing your costume? [he picks up the pterodactyl costume] I stayed up all night making it!
Potty: [squawk] You're wasting your time, old man. Prehistoric stuff is lame. Everybody knows the future's where it's at.
Patchy: What?! [laughs nervously] That's not true! Don't mind him, folks. Why even Tino Tonitini knows that prehistoric stuff is, what the kids say, [air quotes] cool.
Potty: [squawk] No he doesn't.
Patchy: Yes he does.
Patchy: He most certainly does.
Potty: No he doesn't.
Patchy: Yes he does!
Patchy: [angry] I know for a fact that he does!
[Patchy fumes. Cut to a screen reading…]
[cut to Tino is on a date with Sunset Shimmer]
Sunset Shimmer: Tino! What's wrong?
Tino: I don't know, Sunset, but I've got this strangest feeling that somewhere a pirate and parrot are arguing about me. [close-up on Tino's face] And the parrot is winning. [cut to Patchy and Potty]
Patchy: Does! Uh, look, while we're arguing, why don't you folks go ahead and watch "Wrath of the Indominus Rex"! Roll the cartoon! …does.
[the movie starts in a forest and we see two eggs and they hatched and the 2 dinosaurs inside, purring]
[2 months later]
Peter: Hey Brian, got any idea for today, because I'm bored.
Brian: No, not yet. Think Brian! Think! Think! [has thought up of something] I've got an idea maybe we can go back to Jurassic World and film the whole park and show it to the people to convince them to get it back n business.
Stewie: What?! Are you crazy!? Did you forget?! The Indominus Rex! I-N-D-O-M-I-N-U-S-R-E-X! Indominus Rex!
Meg: Come on Stewie, she's dead now.
Louis: Yeah she got eaten.
Peter: Well, all I know is Brian's idea is the best. So let's go tell the others.
Rainbow Dash: Awesomest Krabby patty ever!
Lor: Hey SpongeBob, what do you call it?
SpongeBob: The Awesomest Krabby Patty in the world.
[Stewie shows up]
Fluttershy: Hello Stewie, what's the news?
Stewie: Okay, we're going back t Jurassic World so we can film it to convince the people
Carver: Wow, that's great news.
Stewie: GREAT NEWS!!!? More like bad news, if you ask me!
Patrick: What do you mean?
Stewie: The Indominus Rex! Remember?
Tish: Yes, but she's dead.
Pinkie Pie: She got eaten by the Mosasaurus.
Applejack: Don't worry about it.
Stewie: Is suppose you're right, maybe I'm getting ahead of myself so, let's go.
Sandy and Rainbow Dash: Awesome!
[At Canterlot High]
Sunset Shimmer: Tino?
Sunset Shimmer: You think that uh... ...we get married until we're grown up
Tino and Sunset Shimmer started to kiss as Brian was watching]
Brian: Hey guys
Tino: Oh! Hey Brian! We didn't see you there.
Human Rarity: So what's the news?
Brian: When Tino and Sunset Shimmer made a cute couple, I just came up with an idea for this summer.
Human Pinkie Pie: Let's hear it.
Brian: We can go back to Jurassic World to film the whole park and try to convince the people to get it back in business.
Tino: Jurassic World? Was that place destroyed by the Indominus Rex, last time we've been there?
Brian: Yes, but she's gone and problem's solved
Sunset Shimmer: He's got a point. But Let's go.
Doraemon: Is everyone ready?
Noby: It'll be so cool!
Sue: I know, right!
Carver: Imagine! If we get it back in, we're going to be rich.
Mr. Krabs: "Rich!?"
Sneech: Yes rich!
Dora the Explorer: How are we going to get there?
Tino: On a boat of course.
Chris G.: We'll make millions of dollars. The video will be a hit!
Matt: Well what are we waiting for?! Let's go to Jurassic World!
Tino: But first, we've got to start packing, because this...
Sunset Shimmer: ...is going to be a bumpy ride.
Tino: Man, you're short of a mind reader, Sunset Shimmer.
Shido: That's right. Let's get started!
