[Opening note: The Rick and Morty theme starts, but it’s glitched with the Gravity Falls accordion and Owl House spooky flute.]

VISUAL MONTAGE

1. Rick’s Portal Gun opens a swirling vortex — but instead of green, it’s covered in glowing glyphs and Bill Cipher’s eye symbol.

Rick and Morty dive in.

Ford pops out with blueprints.

Eda stumbles through with Owlbert.

2. Quick chaotic cuts (classic R&M style):

Mabel rides a levitating Waddles while firing glitter cannons.

Dipper frantically scribbles in a new “Journal 4” as Hooty crashes into him.

King strikes dramatic poses on top of random cryptids.

Stan chases after flying dollar bills.

3. Villain flashes:

Bill Cipher grins, glitching into Belos’ masked face, then back.

A gnome army sprouts demon wings.

The Bat-Elk abomination roars.

4. Hero shots:

Rick and Ford tinkering with a glowing portal core.

Eda mid-owl-beast transformation.

Morty screaming, running from both.

The kids + King + Hooty tumbling into the chaos.

TITLE REVEAL

The words “RICK & MORTY & GRAVITY HOUSE FALLS” slam onto screen in neon slime letters…
…but then it glitches violently:

“Rick & Morty” text oozes green portal goo.

“Gravity Falls” letters crumble into pine needles and question marks.

“Owl House” glyphs glow and burst into feathers.

All three logos fuse into one horrifying mashup… then collapse into static.

FINAL GAG (like Rick & Morty intros always have):

[INT. MYSTERY SHACK – LIVING ROOM]
Rick, Morty, Ford, Eda, Dipper, Mabel, King, and Hooty all cram onto the couch.

MORTY: Uhh, guys, are we, like… one big show now?
EDA: (groans) Great. Just what I needed. More children.
MABEL: (cheerfully) Family bonding time! Sweater montage!!
HOOTY: (loud) I’M THE MAIN CHARACTER! HOOOOOT!
RICK: (sighs, pulls flask) Kill me.
