(If you all ask why I deleted my Magical Mystery Mirror. Its because I thought I could do a much better job with the crossover plot)

On one boring day in Princess Twilight Sparkles castle of Friendship, she just sat there reading all of her books in her castle library for more than forty-three times (now forty-four) all alone with Spike.

Twilight: "*Moans in boredom* AUGH I'm so BOOOORED I've read all of these books and yet I still can't find anything interesting to around here."

Spike: "*Reads his comic book* Don't worry Twilight I'm pretty sure that the magical map will assign you a friendship problem as usual *flips a page*"

Twilight continues flipping through her books until she came across of what is aperies to be a very dusty cuboid shaped object.

Twilight: "Wait have I always noticed that this was even here? Probably not"

Twilight blows the dust off of the object has hard as she can, only to find-out that it's actually a very old book will a golden six-fingered hand on it with the number 4 printed on the hand.

Twilight: "*Reads the stuff that she sees in the journal out loud* This is so weird… Septiceye Sam, blue Yeti's, Cockroaches that can do the jiggy conga dance, a magical mailbox that can answer every question in the universe, land of the magnetic boulders, teleporting doughnuts…"

Spike: "*Peaks over Twilights shoulder to see what's she looking at* Whatcha reading Twilight?"

Twilight: "Just some weird old dusty book with some of the weirdest stuff I've ever read"

Spike: "Let me see *takes a look at the journal and reads out the stuff that he sees in order" My adventures with Rick Sanchez, how to make crystal tears step by step, what to do if you encounter a talking Flower, guide to cursed animatronic bears. Dude [sighs] what am I seeing here *pulls out a orange gem and munches on it*"

Twilight: "Wait theirs some info on my species. *Reads more* Wow in fact I have no idea that who ever wrote this journal, must have also done some research on Equestria. From magical spells like the ones I study, pony biology to the history of Equestria its self. I didn't even know that he/she had to take on Nightmare Moon with some kind of something he calls a 'Quantum Destabilizer' gun"

Twilight uses her magical horn to flip through the pages of the journal; ignoring the most random things that she and Spike sees until something caught her eye.

Twilight: "Wait what's this? A spell that can create an extra-universal gateway to a place called 'Gravity Falls' Oregon.

Spike: "Gravity Falls?"

Twilight: "*Continues reading* Its says that in order to activate the spell you must read out these safe words while having to charge the portal with a specific source of powerful energy or magic. That's not so difficult I could call over our friends and tell them that I found a very 'interesting' spell to cast and a world where no pony has gone before hoof. Besides my brain felt like it was dead; with no ideas on what to do sense Starlight Glimmer reformed the Changeling Kingdom. And it felt like months"

Spike: "*Looks at the portal section of the journal and found something unpleasant* But Twilight this says in big bold red ink *points to wear it is* 'warning: do not cast this spell or else it could alter the fabric of both worlds"

Twilight: "Spike I accidently swapped our friends cutie marks before. Besides with a spell like this I could be a hay of a lot fun to find out what we're dealing with. If this author is so interested in Equestria then we could see what he/she is hiding"

Spike: "Alrighy then. Just say that the journal didn't warn ya. *Hops onto Twilights back*"

Twilight: "That's the spirit lets go"

Twilight and Spike takes off with the journal in the palm of Spikes hands to invite their friends to foolishly activate the portal. But what they don't realize that behind them is a shadow in the shape of a triangle with limbs stalking their movements.

?: "*Disoriented voice* SOON, VERY SOOOOON!"
