Mabel: [Mabel wake Dipper from his bed]Get up, Dipper! It's time!

Dipper: [barely waking up] Time for what?

Mabel: The big shin-dig! Remember?

Dipper: No, besides, I don't really think my shins should be involved. They're a bit flabby today. [wiggles his foot]

Mabel: That's shin dig, bro bro. We're spending the day at the beach in the honor of our siblings ship.

Dipper: The beach! Just you and me!? [Mabel took off her nightshirt showing her red bathing suits; Dipper rips off his clothes he forgot he didn't wear his swim trunks just his underwear.] Can you turn around Mabel. (Mabel turn around and not to see Dipper underwear.) You can turn around now. (Mabel turn around and see Dipper in his white t shirt and his red swim trunks. So am I ready for the beach, Mabel?

Mabel: Sure. A little sunscreen and I'm sure you'll be fine! [Meanwhile the bus coming by. Dipper and Mabel shove a huge bag of stuff onto it] I'm spending the whole day at the beach with my favorite brother. [shoves her bag onto a seat with someone sitting in the seat. Dipper and Mabel both cram themselves on the same seat along with the guy]

Guy on bus: You're hurting me!

Mabel: [taps the guy in front of him on the shoulder] Guess what?

Person in front of him: [sigh] What?

Mabel: I'm going to the beach with my favorite brother ! [taps the bus driver's shoulder] Ooohhhh buuusss drrrivvver!

Bus driver: What?

Mabel: Okay, out of everybody on this bus, guess which one is my favorite brother?

Bus driver: I don't care.

Mabel: You know what this situation calls for. this guy he number 1 ! [Mabel takes out a keyboard guitar, and Dipper takes out his tuba] A few verses of the best sibling tune! [Dipper and Mabel start playing and singing] Ohhhh best si- [the bus stops and Dipper and Mabel are kicked off it] Hey! Wait! This is not our stop! Oh, how are we going to get to the beach now, Dipper? We don't even know where we are.

Dipper: I knew it! We've been abandoned! I knew our singing got kick us out.

Mabel: Doomed! [Mabel starts sobbing] Oh, you're right, Dipper! No one is ever going to find us out here!

Volleyball player: [hits Mabel in the head with a volleyball] A little help, bro?

Mabel: Look, Dipper! We made it! Hey best bro? Check this out! [turns around and her bag appear to be sagging. Reaches in her bag and takes out a Frisbee] It's a small plastic disc that you throw!

Dipper: Small plastic disc did you mean a frisbee.

Mabel: Perfect! Now run along, Dipper, and I'll [winks] toss it to you!

Dipper: [runs]

Mabel: Ready?! [throws Frisbee. Dipper is running . He steps on two people and kicks sand in a guy's sandwich]

Nate: Ha ha ha! That's why they call it a sandwich! [Dipper kicks sand in his mouth while trying to catch the Frisbee. He almost runs into a pane of glass being carried by two workers. He crashes through an ice cream cart, and then into a lifeguard tower]

Dipper: [Underneath rubble of the lifeguard tower, Frisbee lands in his hand] I caught it! [Pants] Wasn't that cool, Mabel?

Lifeguard: [pops out from underneath the tower rubble] I can assure you, that was not cool! Just look at what you've done! Your buffoonery has destroyed the lifeguard tower! Why don't you find something to do that's less obnoxious?

Dipper: Like what?

Lifeguard: I don't know, go play in the sand or something!

Dipper: Well, I don't know. Playing with the sand sounds pretty boring.

Mabel: Nonsense, Mabel. There are plenty of fun things to do in the sand. We can draw, or practice our cursive writing, or...

Dipper: Boring, Mabel, boring!

Mabel: I know, we can make sand castles!

Dipper: That sounds [elbows Mabel] un-boring!"

Mabel: No one's ever been annoyed by a sand castle. [Laughs. Mabel constructing a sand castle. Mabel talks to the man he has drawn in a window of his castle] Nothing quite like the joy of sand castling, eh, Dipper? [To Dipper] How ya doing over there?

Dipper: [patting sand] Everything's dandy in Dipper's Kingdom.

Mabel: Oh, a structure like that can't protect a queen and her subjects. Here, let me help you. First, you should start all over. [begins rubbing down Dipper's sand mound]

Dipper: Whoa! What are you doing!? You destroyed my castle!

Mabel: I'm just trying to help, bro bro!

Dipper: Well, I don't need any help.

Dipper's architect: Here are those architectural plans you requested.

Dipper: Why thank you. Here's a little something for you. [hands architect sand money which promptly disintegrates in his hands]

Mabel: Well, I suppose I should just tend to the affairs of my own realm. [to the little man in his sand castle] And I'll start by making a queen to rule by your side.

Dipper: [throws a ball of sand at Mabel's castle, destroying it] Now, we're even!

Mabel: All right, Dipper, have it your way. [Draws a line in the sand separating the two of them] "You keep to your territory and I'll keep to mine. [mumbles to herself and quickly builds an even larger and better castle]

Dipper: ['looks at his plans] Now, this'll show Mabel that she's not the only one who can build a castle! Let's see Mabel destroy this castle! [builds a castle with spikes on top and a skull and crossbones symbol on the door]

Mabel: [After seeing Dipper's new castle] I better build a wall just in case King Pinky gets any funny ideas. [starts building a wall, but then notices that Dipper's castle is over the borderline] Oh, sir, you built onto my side.

Dipper: So?

Mabel: [mad] So, you don't do that! [kick off the portion of Dipper's castle that is crossing] There! That restores the integrity of our shared border.

Dipper: You tyrant! You've done it again! I'll show you what for! [Builds a hammer out of sand and charges toward Mabel's castle]

Mabel: But what for what!?

Dipper: [attacks Dipper's castle, completely destroying it] Now, we're even... again!

Mabel: Okay, Dipper, I can accept that. No more destruction from this point forward, okay? Okay, back to square one again. [builds this huge castle and Dipper does the same. Mabel blowing a medieval horn] I hereby propose a non-aggression treaty to end hostilities between our two kingdoms. [Dipper signs Mabel's sand made treaty] Dipper, by signing this historic armistice you have brought peace to our lands. May your kingdom prosper! Well that went well!" [Dipper shoots a sand arrow at Mabel's castle] What are you doing!? What about the treaty!?

Dipper: This treaty isn't worth the sand it's printed on! [Treaty disintegrates]

Mabel: Oh, is that so!?" Well, if you think you can take down this castle, my answer is bring it on! [Dipper laughs and builds an army of knights. Mabel clears her throat] Dipper, I'm trying to be the nice girl here, okay? Let's call this silly business off.

Dipper: No way! You started it.

Mabel: Fine! Have it your way.

Dipper: [laughs menacingly] Whatever. [Mabel is loading a catapult, the catapult shines, and Mabel raises his eyebrows] No no no no no. [Mabel chops the catapult rope. Dipper screams as the sand rocks from Mabel's catapult hurl toward him destroying Dipper's army. Mabel laughs and blows another horn. Mabel's army emerges from his castle and charges toward Dipper. Dipper screams again. Mabel's army starts to ram down the door to Dipper's castle. Dipper panics and builds a cannon. Mabel's army breaks the door] Oh hello! And goodbye. [pulls cannon's string. Mabel's army rushes in his castle away from the cannonball]

Mabel: Come on! [closes the door to his castle] How do you like them apples? [Cannonball goes over the wall and destroys the army]

Dipper: [laughs from atop his castle] You'll never win! Do you hear me!?

Mabel: [now inside a high tech sand castle] Uh huh... mmm hmm. Well put, general! We'll create a surprise military diversion and break through enemy lines. What say you? [Sand constructed general starts to fall apart] Yes! We'll ready ourselves immediately! [builds a tank that then crashes through her own castle and towards Dipper's] How do you like me now?

Dipper: [has a robot already built that punches through his own castle] I like you this much! [picks up Mabel's tank with Mabel screaming inside] Feel me!

Mabel: [screams again. She presses a button in his tank blowing up Dipper's robot. She emerges from her tank and sees Dipper unconscious inside her robot head]Dipper... Dipper! Are you okay!?

Dipper: [quickly recovers, whispering] The question is... will you be!? [presses a button in his robot head. The robot flies into the air with Mabel still hanging on. Mabel looks down and sees how high up she is. She then slips and falls through the sky. Then she pulls a sand parachute and laughs] No fair!

Mabel: [Floating gently down] All is fair in love and war my brother slash enemy, or should I say, my brother-enemy!? [presses a sand button. Falls into her jet waiting in midair. Mabel presses a button in her jet while chasing Dipper's robot head] Now let's have some real fun! [Missiles fly toward Dipper. Dipper screams as he turns his robot away from the missiles]

Beach onlooker: [to the person next to him] What was that!? Come on, we got to get out of here! [More people on the beach scream and run away]

Dipper: [calm now] Oh, yeah? Two can play at this game! [Presses button. Patriot missiles emerge from the ground and fly toward Mabel]

Mabel: [seeing the missiles] Jumping gnome! Whoa! [Turns the plane down, does a loop, and crashes the missiles into Dipper's castle. Mabel laughs. Dipper's robot meets Mabel's in the air]

Dipper: I wasn't going to do this, but you've left me no choice. [Dipper drops an atomic bomb on Mabel's castle]

Griffin: [gasps] Let's beat it, dude! [He and another griffin fly away as the bomb explodes and destroys the sand castle. Dipper laughs menacingly. Dipper is interrupted by a furious Mabel flying her jet directly toward Dipper. Dipper has a worried look on his face. Mabel's jet then crashes into Dipper's robot head, causing an explosion and knocking them both out]

Mabel: [laying on the ground in pain] Ohhhh.

Dipper: [also laying on the ground in pain] Ohhhh. What happened?

Mabel: I'll tell you what happened, Dipper... I got carried away.

Dipper: Me, too...was it worth it?

Mabel: No, no, it wasn't. What started out as a fun dream turned into a horrible, brutal, nightmare. As the winds of time changed the silvery sands of these dunes to a new landscape, so let us hope that our own winds of change will change our spiritual dunes to a landscape of peace. Oh Dipper, let's never forget this lesson awkward sibling hug.

Dipper: Awkward sibling hug Dipper & Mabel: (Hug and pat each other) Pat, pat.

Lifeguard: Let's also not forget who's going to clean this place up. [camera pans around showing the destruction caused]

Dipper and Mabel: Oooh, uhhhh, ahhhh...

Lifeguard: [gives Dipper a dustpan and hands Mabel a broom] Better get started! You've got a lot of work to do.

Dipper: I bet I can clean up faster than you!

Mabel: Oh yeah? I bet you can't!

Dipper: Yes, I can!

Mabel: No, I can!

Dipper: Oh, I can!

Mabel: I can!

Dipper: Hey, look at this!
