Garfield's Adventure of My Little Pony Equestria Girls
As the opening credits ends, the camera pans down from the title back to the Crystal Empire.
It was night time. Peaceful, but there were night guards securing the area.
Inside of one of the Crystal Empire hallways, there was also a guard securing the castle. We zoom in to a pair of double-doors, and we see a flash of light come through the keyholes.
A creak for one of the doors open, revealing a mysterious stranger. The stranger, wearing a black cloak and hood then sneaks past the guard, who doesn't notice the stranger. We cut to Garfield and Twilight's bedroom, where the stranger opens the door with her magic.
"Lasagna...Naps...Diets...", Garfield snores, sleeping while the stranger opens the door.
It then sneaks past the sleeping Spike and restrained Nermal, and stops near the drawer with Twilight's crown. It uses her magic to levitate the crown, but it accidentally makes the lamp about to fall. Before the lamp was about to hit the ground to wake the others up, but it only makes Garfield snore: "...Pooky...", pulling out his symbolic teddy bear to snuggle with.
Putting the crown with the translucent jewel in it's pocket, the stranger switches it with a fake crown with an opaque jewel.
Walking out the room, she accidentally trips on Spike's tail/Nermal's feet, thus waking the two up.
Nermal tears apart the straitjacket and spits out the Hannibal-like mask out of his face, yelling: "INTRUDER! INTRUDER!"
Garfield, Twilight and the rest wake up, while the former asked: "Is it morning already?"
Suddenly, they see the intruder and Twilight's crown in it's pocket via a twinkle with the jewel sticking out. Twilight was the first to notice and alerts: "My crown! SHE'S GOT MY CROWN!"
The intruder then makes a run for it while Twilight, Garfield and the rest chase her.
"STOP! THIEF! SHE'S STOLEN MY CROWN!", Twilight screamed, chasing her with Garfield, who still has Pooky in his hands. Odie, Jon, Liz and the others are behind the two.
Twilight during the pursuit, teleports while Garfield ran at lightning speed to catch up with Twilight, with the cat holding out Pooky insulting: "STOP! I HAVE A TEDDY BEAR AND I'M NOT AFRAID TO USE IT!"
The intruder then teleports like Twilight as well, putting the cloak and hood on Twilight and Garfield's sight.
She turns back to reveal a yellow pony, with a red and yellow mane, a horn like Twilight and Rarity's, and a cutie mark with the symbol of a sun, still with the sack holding the crown.
Garfield and Twilight growling with anger, they then continue to chase the pony with the rest. The two formers, almost reaching the pony, then lunges at her, ending up in a room with artifacts.
The crown launches out of the sack, hitting the wall, the glass case for one of the artifacts, the floor, and shockingly...the mirror. Instead of breaking it, the crown is sent to a mysterious place inside the mirror. The 12 gasp, except for the intruder, who smiles evilly.
"What did you do to my crown?!", Twilight interrogated.
"ANSWER!", Jon shouted at the top of his lungs, joining Twilight.
"Sorry it had to be this way...", the intruder bragged, before teleporting near the mirror, finishing: "..."tabby cat and princess"!"
The intruder then jumps into the mirror, leaving everyone gasping.
"What the?! It is 4:30 in the morning and we woke up for this?!", Liz hollered.
"I don't know what just happened. She must've come from another world.", Garfield thought.
"And who was that?", Fluttershy asked, traumatized of what has happened.
"Bark, bark, woof, yip, bark, woof, yip, yip!", Odie explains, but can only make dog sounds.
"What did he say?"
"He says, "We'll need to find out in the morning."", answers Garfield. "We need to find that crown before it falls into the wrong hands."
