Young Mac - In a squeeky voice, "If you were a small stuffed doll that was forced to be wanted by everyone in ponyville cause of a magical spell. I would swoop in and rescue you."
Smarty Pant - "Gee.... aaww thanks kid. That's some imagination you have there."
Little did Smarty pants know that she would later be turned into a small plush doll by an evil gypsy curse (not pinkie or pinkie relative) and sold to a small filly Twilight. Who would later be so desperate to right a letter to her teacher that she would take poor Smarty Pants out of the toy chest just to use her. Thus meeting Mac again all grown up who recognized it was her though the eyes of love (YES THE EYES OF LOVE) and rescues her from certain doom. To later be freed of the curse when Mac kisses the Plushy like some kind of ..... frogy.... plushy... ummm princess. Yah! So she changes back and thus realizes that they were meant to be, they fall in love, have babies.... THE END!
One day shortly after getting her cutie mark, filly Twi was exploring the enormous Canterlot library when she had one of her uncontrollable magic surges. When she came out of it, she was relieved to find everything around her appeared to be unharmed. It seemed that any spells she'd accidentally cast were undone as the surge wore off, just as had happened during her entrance exam. She resumed her reading for a while and forgot all about the incident.
Hours later as the library was closing, she found the most adorable little doll sitting on a nearby chair. Having no recollection of any other recent young visitors, the old, nearly deaf librarian had no idea where the doll could have come from, and the innocent look in Twilight's eyes was enough to convince her that the little purple filly should keep the doll, much to the youngster's delight.
Little Mac always wondered what happened to his first childhood crush, but he never gave up hope of one day seeing her again, even as years passed with no word. Then one day out of the blue, his hopes surged to new heights when Ponyville's latest commotion dropped a perfect likeness of her right at his hooves. It had to be a sign. She's gotta be out there somewhere...
That's right lol but going off what I said it's really funny that Rarity's mom WOULD wear something so out of date because I can imagine Rarity growing up being so embarrassed by how her parents dress, just a fun thought thanks for bringing that up!
