Pinkie knew that the spell had gone horribly wrong, and she wasn't complaining. Twilight wanted to see if there were other universes like the human world or her own, and see if she could travel to them. Fortunately for Twilight, she found a spell to open up dimensional rifts to other universes, but unfortunately for Pinkie Pie, she was the test subject.
Pinkie saw past the fact that Twilight as kinda distracted and made this dimension a new beginning. Sure, she had no way of getting home, but she was in a place with ponies that were her type. It might not even be that hard for her to hook up here!
Pinkie walked around this new Ponyville, and smiled at all the ponies she saw, as well as giving them a wave. She walked into Sugarcube Corner, only to find herself handing upside down. She heard a cackle of laughter come from somewhere inside the confectionary, and the Cake couple came walking out of the kitchen, both of them laughing like school foals who have seen the 'tack-on-the-teachers-chair' trick work for the umpteenth time.
"H-H-hey, Pinkehay, just hanging around?" Mister Cake joked.
"Looks like you've gotten tied up in a sticky situation, but just hang in there!" Missus Cake said.
Pinkie, who was looking at her hindlegs, which were tied up with a brown rope, was now feeling blood rush to her head. ShShe looked at the couple before her.
"Ehehe, yeah. It looks like I've gotten all hung up. Can you untie me now, please?" Pinkie asked.
"Sure, why the fuck not." Mister Cake said. Pinkie liked the fact that this universe was so carefree, nopony even cared if they swore. But, if the camera was rolling, Pinkie wools have told off Mister Cake, saying stuff like, "this is a kids show" and "kids are watching this" but, a since they weren't, Pinkie didn't do so.
Mister Cake walked up to Pinkie and started untying the rope that was around her legs. He took his time, not caring if Pinkie desperately needed to stop the pain in her brain.
"I'll catch you," Missus Cake says, as she lifts up her forelegs under Pinkie.
When Mister Cake finished, Missus Cake quickly withdrew her hooves and Pinkie's head collided with the hard floor.
"Oh Celestia, owwww...." Pinkie said, as she got to her hooves, pain lacing her voice. She was rubbing her head, and scrunching up her face in pain.
"Hah! Psyche!" Missus Cake exclaimed while giving Mister Cake a brohoof. The rest of the shop roared With laughter by this Point, and this just made everyPony go wild. Pinkie Soon joined in, seeing what has just happened as a joke.
''now," Missus Cake started, "GET TO WORK!!!!"
Pinkie nodded, did a salute, and ran behind the counter. She served the ponies that came and went, most stallions joking about her plot. She knew they were joking, though. So she didn't mind. AT ALL.
Before Pinkie knew it, the bakery had to close. It was a good day, a million jokes and a million laughs were had. But the fun had to end eventually. Pinkie just went to bed without a word. Her dreams were filled with vanilla, ice cream, and messages to Hasbro to stop throwing PinkieDash material everywhere.
