Construction was heard. Hammering. Screwing. Drilling. Wiring. All that stuff. When it faded to normal, Garfield climbs between the mirror symbol and the upgraded mirror to slap in a magnet with a symbol of Garfield's face on it. He then jumps down with Odie as Twilight mathematically observed:

"And the interval between the two points is defined as the square root of the sum of the squares of the seperation between the two points along three spatial dimensions."

"TA-DA!", Garfield cheered with Odie barking as loud as he could, the other five Garfield characters applauding.

"Say what now?", Spike questioned the equation what Twilight said, along with Nermal saying this too.

"Duh! They're gonna take the magic in here and put it in there!", explained Pinkie, telling the main reason of the contraption the three made.

"Exact-ic-ally!", Squeak knew it.

"That'll make the portal open up so that whenever they want to, they can go from here to there!", examined Pinkie Pie, some if the book is placed as the contraption, the eight will once again go back to the alternate universe. She then says "here to there" vice versa and back many times, before Applejack, annoyed with the other twelve and Arlene stops her.

"We get the idea.", rushes Applejack and Arlene.

"Now you do the honours of putting the book into the contraption, Twilight.", Garfield requested.

"Thank you, Garfield. Now to see if it actually works."

Twilight then steadily places the book into the contraption on top and it bursts into a purple star. The two light round lightbulbs at the top blink, and the purple star explodes to connect Ghostbusters-like streams into the swirly lightbulbs, sparkling purple electricity as it goes. The rest of the thirteen are astonished by this.

The purple electricity then surges down the rest of the contraption, lighting up one of the wires and activating a pumping system, which the magic pours down the rollers. Finally, the electricity then flows through the cables and stops at the two antennas for each side. Both sides amalgamate a purple portal and zaps into the mirror itself, connecting to the mirror's symbol and Garfield's symbolic magnet.

A flash of white blasts, and a purple swirly pathway is opened.

"It works! IT WORKS!", Garfield yelled with glory, with he and Twilight smiling at their friends. The rest of the twelve are once again astonished by the finale.

"Now we can go back to help our CHS friends!", Liz and Arlene jinxed, high-fiving.

"Don't suppose we could join you guys this time around?", hopefully asks Applejack.

Twilight answers, "Better not. It could make things pretty confusing if Canterlot High all of a sudden had two of all of you."

"And there might be a hole ripping in the space time continuum if that happens.", warned Garfield allegedly, as the five ponies look at each other and agreed with both the princess and the cat's explanation.

"But I still get to go, right? There isn't another one of me at Canterlot High, and you never know when you might need your trusty assistant.", excused Spike.

Squeak, the new assistant of Garfield, excites by adding, "And me! Can I go too, since you went last time? I like to see what the new world looks like!"

Twilight comes to him and nods "yes".

"Well, since you were with us last time, yes, you can come.", Garfield said to the dragon, with Odie licking his face in agreement. "And as for you, Squeak, since you are a new assistant to us six Garfield characters, Twilight and Spike, you can come as well."

"Yes!", Squeak and Spike reacts, hugging happily to join the seven once again to the adventure.

Garfield, Twilight and Odie then comes across to the five ponies.

"We won't be gone long.", promises Twilight, as she group hugs his five best friends in the whole land, saying goodbye to her and the other eight. Pinkie was the most greeting one to hug Twilight and smile at her.

Garfield and Odie gathers Jon, Liz, Nermal and Arlene with Squeak for the adventure back to CHS.

Twilight then comes back to Spike with the nine in front.

"Ready, guys?", Twilight prepared.

"Ready!", Spike, Garfield, Jon, Liz, Nermal, Arlene, Squeak and the woofing Odie readied, hearts pounding for the return to CHS as they stance like an Olympic runner preparing to run.

"No retreat...NO SURRENDER!", Garfield and Squeak roared, as the eight, one by one, ran towards the swirling purple pathway.

In the portal again, Twilight, Spike and the seven Garfield characters in front, fly like if they were in Neverland. Their POV was like going through a vortex with IMAX rumbling basses due to the intensity and with IMAX colourful images included. It was like a MLP version of Interstellar, but with the Equestria Girls universe.

Garfield and Odie had the urge to howl again due to travelling at a lightyear speed rate.
