This is my ideal episode for Gravity Falls, A Gravity Falls/Phineas and Ferb Crossover!

(scene shows Dipper and Mabel in their room, Mabel just laying on the bed while Dipper is reading the book)

Mabel: I'm bored. I wish something exciting with danger and mayhem happens!

Dipper: (looks at a word in the book) Hmm, I wonder what this word means.

Mabel: What do you mean?

Dipper: Ztrimhsnefood.

(as he says this word, a portal opens up)

Mabel: Whoa! I wonder where this leads!

Dipper: Better let me go in first. (he puts down the book and enters portal)

(Dipper is shown in the backyard of Phineas and Ferb)

Mabel: Cool. (looks in window door) Hey look, we're more-ly animated.

Dipper: I wonder where we are? (he leans into the tree and presses a button and slips into the tree)

Mabel: Dipper! (follows Dipper)

(meanwhile, Phineas and Ferb wake up and walk into the backyard when they see the portal)

Phineas: Whoa, a portal. Cool!

Isabella: Hey Phineas. Watcha doin'?

Phineas: We've discovered a portal!

Isabella: Wow! We should go in!

(they go into the portal and are in Mabel's and Dipper's room)

Isabella: Whoa, where are we?

Phineas: (picks up the book) I'm not sure, but look at this book. (looks through book) Wow, look at all this! Ferb, I know what we're gonna do today! We're gonna have an adventure!

(theme plays (the theme is similar to Jimmy Timmy Power Hour; the way that 2 theme songs play at the same time))

(Mabel and Dipper enter Perry's lair)

Dipper: Where are we?

Mabel: Cool, a jet pack!

Major Monogram: (appears on the screen) Morning, Agen-Great googly moogly! Carl, who are these kids?

Carl: (off screen) They must be Agent P's owner's friends.

Dipper: Um, what's the mission?

Major Monogram: Um, I guess I'll just give you the briefing. Doofenshmirtz has been seen in town and going through a strange portal. You need to go to Doofenshmirtz Evil Incorparated and find out what he's been up to.

Dipper: Thanks. Come on, Mabel. (they get on the hover car)


Phineas: Wow, check this out guys. Gnomes, manotaurs, and ghosts! I wonder what we should do first. (they head downstairs when they see Wendy and Soos)

Soos: Hey, where's Mabel and Dipper?

Isabella: Hi.

Phineas: Who's Mabel and Dipper?

Wendy: They are 2 kids that live here.

Phineas: They must have made that portal that lead to our backyard. But how did they do that?


Doofenshmirtz Evil Incorperated!

Dipper: Well, this is the place. (enters room and is heard screaming)

Mabel: Dipper! (enters room and sees Dipper in a trap)

Doofenshmirtz: Ah-oh, sorry about that. I wasn't trying to trap you, I was gonna trap someone else. But, now that you're here, I guess I should tell my latest invention! Behold, the Mute-inator!

Mabel: The what-inator?

Doof: The Mute-inator. It makes everyone that it zaps speechless.

Dipper: (gets free of trap) Who are you again?

Doof: I'm Heinz Doofenshmirtz.

Dipper: Doofenshmirtz? That name sounds familier. I won-(sees that the book isn't in backpack) Hey, where's the book?

Mabel: I think you left it in the room.

Dipper: Oh, darn it!

(at the Flynn-Fletcher house)

Linda: Candace, I'm gonna go to the grocery store to get some things. Until I come back, you're in charge.

Candace: Ok, mom. (goes outside to the backyard) Mom sa-Hey, where are they? (sees portal) Ugh! Phineas! Ferb! Come out now! Ugh, if you don't come out, then I'll take you out on my own! (enters portal)

Dipper: I guess we'll head back.

Doof: Ok, nice seeing you!

(as they are about to leave, Perry enters the room)

Mabel: I think that's Agent P.

Dipper: Uh, let's just go.

Doof: "when they leave" Ah, Perry the platypus! Who were they? Oh, I don't know. Well, I was gonna fire up a new invention called the Mute-inator, but then I decided, since I haven't really shot it yet, why don't I fire up the Forget-about-it-inator!

Phineas: I can't wait when we have a real adventure in this book! (sees Candace) Oh, hey Candace!

Candace: What are you guys up too and where are we?

Phineas: Well, according to Soos and Wendy, we are in Gravity Falls.

Candace: Who are they?

Phineas: Two people we just met.

Candace: Whatever, I'm taking you 2 to home now.

Phineas: Ok. (he leaves the book on the counter near Soos)

Dipper: Well, here we are again.

Mabel: I think I remember that word now! It's Ztrimhsnefood. (when she says this, the portal closes) Whoops.

Doof: (it shows Perry stuck in glue and sand paper) Ah ha! Now you are stuck! At last, I am finally gonna fire it up! (fires the inator)

Dipper: Don't worry Mabel, It's... (him and Mabel get hit by inator) ...what was I talking about?

Mabel: I don't know.

Dipper: Uh, Mabel. I think we lost the password back to Gravity Falls! Now we're stuck here!

Mabel: "gasps"

Candace: I know the portal was around here somewhere!

Isabella: Maybe it dissappeared!

Phineas: If it dissappeared, that means we're stuck here!

Isabella & Candace: "gasps"
