PONYVILLE 1:00 PM

Everywhere was peaceful in Ponyville. Everyone was having harmony in Ponyville. Everything was perfect.

And the best part is, the camera zooms to a majestic crystallized castle which is called "The Friendship Rainbow Kingdom".

Inside the kingdom, Twilight, Pinkie, Rainbow, Applejack, Fluttershy, Rarity and Spike were enjoying the luxury of the castle. Even Garfield, Odie, Jon, Liz, Nermal and Arlene like this kind of paradise.

Twilight was reading letters, Pinkie was blowing balloons, Rarity was polishing her seat, Fluttershy, Applejack and Rainbow Dash were moving a crate like moving stuff for a new house.

"This is the life.", Garfield sighed peacefully, enjoying a hot tub bath with Odie while eating lasagna and both watching America's Funniest Home Videos on Netflix.

Also, Jon and Liz were having their spa treatment, and Nermal and Arlene do the same thing, with cucumber slices on Jon, Liz and Nermal's eyes, a towel on his head and on his body like Jon's, and Arlene having hair rollers on her head, with a towel too like Liz's.

While this was happening, a mail pony arrives with books and mail, a big package and a small jar-sized package.

"Did somebody order a week's supply of lasagna?", the mail pony asks the cat, who ordered the lasagna to keep him satisfied. "Excuse me, Princess, where do you want all these books from Princess Celestia?"

"The library.", Twilight answered the mail pony's question. "Third door on your left."

"Even this one that's glowin' and vibratin'?", he asks, seeing one of Celestia's book vibrating like a cellphone. "She also sent this jar is for you."

Twilight uses her magic to float down the book and the jar, giving it to her and Garfield, respectively, with Odie holding the supply of lasagna for him.

Garfield opens the jar to reveal a friendly mouse named Squeak, who is a Garfield character.

"Squeak!", Garfield greeted, happy to see him.

"Garfield!", the mouse greeted. "I'm so happy to see you!"

Nonetheless, Twilight is reading the book that was vibrating and the other five girls come close to see, along with the seven Garfield characters.

"What is it, Twilight?", Arlene and Fluttershy asks Twilight and Garfield, with the former removing the cucumber slices from her eyes.

"It looks like a message to Princess Celestia from our friends at Canterlot High.", confirms Twilight.

"Canterlot High...? It is from another universe?", Squeak asks his cat friend.

"Long story short: We went there before. The eight of us.", Garfield rushed, telling the mouse that he, Odie, Jon, Liz, Nermal, Arlene, Twilight and Spike went to the alternate universe in the first film.

"How is that possible?", Rarity wondered.

"I thought it's only through the portal. Until now.", claimed Jon.

"We don't know, but...it sounds like they need my help!", shocked Twilight, realizing she, Garfield, his friends and a new friend Squeak must go back to the alternate universe to help them.

"We gotta do something about this...", Garfield narrowed his eyes.

In the library, Twilight and Garfield both find an old book to find information about the problem they're recently having at CHS.

"The way Sunset Shimmer described them, We think these new girls sound an awful like...the Sirens.", Twilight found out.

"NOT THE SIRENS!", Pinkie yells as Odie howls in fear. "I don't actually know what that is.", she then whispered to Fluttershy.

"Sounds like a chilling Halloween-like story.", shivered Squeak.

"Oh, it is. But it sounds more like a legend.", Garfield says, in a folklore like voice.

Squeak relieves.

"Twilight? May I do the honours of reading the story?", requested Garfield.

Twilight replies, "Yes, you may, Garfield, my cat friend.", as he starts reading with Twilight beside Garfield and the other twelve listening to this story.

"The Sirens were three beautiful but dangerous creatures, who had the power to charm ponies with their music. But to maintain this power, they had to feed on the negativity and distrust of others. The more of this negative energy they consumed, the stronger their voices became, and the farther they could spread their dark magic."

Garfield is interrupted when he heard his dog friend Odie whimper, scared at this story as well as Fluttershy and Squeak. The rest were listening to the story.

"Odie!", the cat said to the dog, who the latter stops whimpering.

"I don't think I like this story very much.", Squeak and Fluttershy both said, nervous and scared about the sirens. The former screamed: "It's creepy!"

"Alright. Let me continue.", Garfield calmed the scared ones down.

"If the Sirens had their way, they would have divided and conquered all of Equestria. But a certain Starswirl the Bearded wasn't having it. Rumour has it, he found a way to banish them to another world. One where he believed that magic power would be lost."

"Wow. No wonder you wore a Starswirl costume during Halloween and read his unfinished spell.", coincides Garfield, talking about Twilight's past adventures after reading the story of how Starswirl banished the Sirens.

"That world must have been the one where our Canterlot High friends live.", supposed Twilight, worried.

"But Starswirl musta sent them there ages ago. How come they're just surfacin' now?", Applejack asks her.

"We don't know. But if our hunch is right, and it is the Sirens who've come to Canterlot High, this spell they've cast is just the beginning.", Garfield foretold, flipping the previous page of the story of the Sirens.

"Our friends need us. We have to get back to them.", Twilight finishes, as she, Garfield and the other six friends of his start to walk away. Rainbow stops them in their path.

"I hate to burst your bubble, Twilight, but the connection between their world and Equestria will still be totally cut off for a super long time.", unveiled Rainbow Dash.

Pinkie, hearing Rainbow say "bubbles", interrupts into the conversation. "Okay. First of all, if there was bubble-blowing going on, why wasn't I told of it? And secondly, if the connection is totally cut off, how was Sunset Shimmer able to get a message to Twilight, Garfield and his friends?"

"Speaking of who, I did promise her to be nice by the time I get back and- ...Wait.", Garfield pauses, as he and Twilight try to find a solution. They both gasp and say to Pinkie Pie: "Pinkie, you're a genius!", before she, Garfield and Odie run to get something.

"Yeah. I get that a lot. Now about those bubbles...!", Pinkie replies, then deals with Rainbow Dash about bubbles.

Odie pushes in the same crate Fluttershy, Rainbow Dash and Applejack were pushing it to, with the five ponies and Garfield characters witnessing.

"What are you up to now?", Jon sarcastically tells Garfield.

"I have got an idea!", the cat shouts, using a crowbar to cause the crate to fall apart to reveal the same mirror the eight used in the first film.

"The mirror!", Liz astonishes, holding Jon romantically.

Twilight comes back with a few additional parts while at the same time, Garfield and Odie both grab a toolbox co-operatingly and both pets and the princess work on an upgrade for the mirror. The eleven are watching this kind of quick construction.

Garfield picks a screwdriver, screws, glue and some other parts, while Odie picks up a hammer, nails, some wires and a few light bulbs and other parts. The three then work on the portal, with Garfield constructing the upgrade by building it with screws to arrange it, Odie hammering some nails to steady the shape of it and adding light bulbs to it, and Twilight adding a electrical wire, a few other parts and blinding the screen with a wooden panel.
